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.

62-----------------
63
Thomas Hellerce049a02006-07-14 17:51:14 +000064- Patch #1521817: Index range checking on ctypes arrays containing
65 exactly one element enabled again. This allows iterating over these
66 arrays, without the need to check the array size before.
67
Thomas Heller6e1ad2e2006-07-13 17:05:13 +000068- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +000069 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +000070 /dev/null in certain cases; this is now fixed.
71
Thomas Heller47d7a062006-07-12 08:43:47 +000072- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
73 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +000074
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +000075- Because of a misspelled preprocessor symbol, ctypes was always
76 compiled without thread support; this is now fixed.

Georg Brandlad29e632006-06-21 17:45:17 +000082
83Core and builtins
84-----------------
85
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +000086- Bug #1441486: The literal representation of -(sys.maxint - 1)
87 again evaluates to a int object, not a long.
88
Neil Schemenauer0e07b602006-07-09 16:16:34 +000089- Bug #1501934: The scope of global variables that are locally assigned
90 using augmented assignment is now correctly determined.
91
Martin v. Löwisd5cfa542006-07-03 13:47:40 +000092- Bug #927248: Recursive method-wrapper objects can now safely
93 be released.
94
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +000095- Bug #1417699: Reject locale-specific decimal point in float()
96 and atof().
97
Hye-Shik Change6a1cb92006-06-23 21:16:18 +000098- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
99 omit a default "error" argument for NULL pointer. This allows
100 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000101
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000102- Bug #1519018: 'as' is now validated properly in import statements.
103
Neal Norwitz28746ab2006-07-09 22:14:42 +0000104- On 64 bit systems, int literals that use less than 64 bits are
105 now ints rather than longs.
106
Neal Norwitzed657552006-07-10 00:04:44 +0000107- Bug #1512814, Fix incorrect lineno's when code at module scope
108 started after line 256.
109
Tim Peters32a83612006-07-10 21:08:24 +0000110- New function ``sys._current_frames()`` returns a dict mapping thread
111 id to topmost thread stack frame. This is for expert use, and is
112 especially useful for debugging application deadlocks. The functionality
113 was previously available in Fazal Majid's ``threadframe`` extension
114 module, but it wasn't possible to do this in a wholly threadsafe way from
115 an extension.
116
Georg Brandlad29e632006-06-21 17:45:17 +0000117Library
118-------
119
Martin v. Löwis06c68b82006-07-10 22:11:28 +0000120- Patch #1519566: Update turtle demo, make begin_fill idempotent.
121
Tim Peters32a83612006-07-10 21:08:24 +0000122- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000123 environment variable to be set in order to the SDK environment
124 for finding the compiler, include files, etc.
125
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000126- Bug #1515998: Properly generate logical ids for files in bdist_msi.
127
Nick Coghlan2d792252006-07-06 13:47:18 +0000128- warnings.py now ignores ImportWarning by default
129
Thomas Woutersadd19112006-07-05 11:03:49 +0000130- string.Template() now correctly handles tuple-values. Previously,
131 multi-value tuples would raise an exception and single-value tuples would
132 be treated as the value they contain, instead.
133
Martin v. Löwisede77f52006-07-03 13:01:35 +0000134- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
135 even if some data are received.
136
Martin v. Löwis45482392006-07-03 12:28:58 +0000137- Bug #1267547: Put proper recursive setup.py call into the
138 spec file generated by bdist_rpm.
139
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000140- Bug #1514693: Update turtle's heading when switching between
141 degrees and radians.
142
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000143- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000144 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000145
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000146- Bug #1514703: Only setup canvas window in turtle when the canvas
147 is created.
148
Martin v. Löwis7596e832006-07-01 15:33:37 +0000149- Bug #1513223: .close() of a _socketobj now releases the underlying
150 socket again, which then gets closed as it becomes unreferenced.
151
Fred Drake10497c82006-06-29 02:57:48 +0000152- Bug #1504333: Make sgmllib support angle brackets in quoted
153 attribute values.
154
155- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
156 sgmllib ('[' and ']' were not accepted).
157
Georg Brandl1be63af2006-06-28 20:23:25 +0000158- Fix a bug in the turtle module's end_fill function.
159
Brett Cannon53ab5b72006-06-22 16:49:14 +0000160- Bug #1510580: The 'warnings' module improperly required that a Warning
161 category be either a types.ClassType and a subclass of Warning. The proper
162 check is just that it is a subclass with Warning as the documentation states.
163
Georg Brandlad29e632006-06-21 17:45:17 +0000164- The compiler module now correctly compiles the new try-except-finally
165 statement (bug #1509132).
166
Neal Norwitz60373cd2006-06-22 06:30:50 +0000167- The wsgiref package is now installed properly on Unix.
168
Vinay Sajip28e57612006-07-01 10:45:20 +0000169- A bug was fixed in logging.config.fileConfig() which caused a crash on
170 shutdown when fileConfig() was called multiple times.
171
Gerhard Häring762fbd32006-07-02 17:48:30 +0000172- The sqlite3 module did cut off data from the SQLite database at the first
173 null character before sending it to a custom converter. This has been fixed
174 now.
175
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000176Extension Modules
177-----------------
178
Tim Peters112aad32006-07-19 00:03:19 +0000179- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
180 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
181 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000182
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000183- Assigning None to pointer type fields in ctypes structures possible
184 overwrote the wrong fields, this is fixed now.
185
186- Fixed a segfault in _ctypes when ctypes.wintypes were imported
187 on non-Windows platforms.
188
189- Bug #1518190: The ctypes.c_void_p constructor now accepts any
190 integer or long, without range checking.
191
192- Patch #1517790: It is now possible to use custom objects in the ctypes
193 foreign function argtypes sequence as long as they provide a from_param
194 method, no longer is it required that the object is a ctypes type.
195
196- The '_ctypes' extension module now works when Python is configured
197 with the --without-threads option.
198
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000199- Bug #1513646: os.access on Windows now correctly determines write
200 access, again.
201
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000202- Bug #1512695: cPickle.loads could crash if it was interrupted with
203 a KeyboardInterrupt.
204
Neal Norwitza12aa882006-07-06 06:45:08 +0000205- Bug #1296433: parsing XML with a non-default encoding and
206 a CharacterDataHandler could crash the interpreter in pyexpat.
207
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000208- Patch #1516912: improve Modules support for OpenVMS.

Neal Norwitz3b6b8012006-06-27 04:12:58 +0000210Build
211-----
212
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000213- Automate Windows build process for the Win64 SSL module.
214
Tim Peters32a83612006-07-10 21:08:24 +0000215- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000216 Previously, the slight difference could cause compilation errors of the
217 'zlib' module on systems with more than one version of zlib.
218
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000219- The MSI compileall step was fixed to also support a TARGETDIR
220 with spaces in it.
221
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000222- Bug #1517388: sqlite3.dll is now installed on Windows independent
223 of Tcl/Tk.
224
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000225- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000226 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +0000227
Neal Norwitzb15ac312006-06-29 04:10:08 +0000228Tests
229-----
230
231- Call os.waitpid() at the end of tests that spawn child processes in order
232 to minimize resources (zombies).
233
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000234Documentation
235-------------
236
Nick Coghlan2d792252006-07-06 13:47:18 +0000237- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
238 documentation for the warnings module.
239
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000240- Patch #1509163: MS Toolkit Compiler no longer available.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000248
249Core and builtins
250-----------------
251
Georg Brandla56b9152006-06-19 06:35:54 +0000252- Patch #1507676: Error messages returned by invalid abstract object operations
253 (such as iterating over an integer) have been improved and now include the
254 type of the offending object to help with debugging.
255
Brett Cannonea3912b2006-06-13 21:46:41 +0000256- Bug #992017: A classic class that defined a __coerce__() method that returned
257 its arguments swapped would infinitely recurse and segfault the interpreter.
258
Neal Norwitz909eb122006-06-12 02:13:21 +0000259- Fix the socket tests so they can be run concurrently.
260
Neal Norwitzb9845e72006-06-12 02:11:18 +0000261- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000262 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000263
Brett Cannon22565aa2006-06-09 22:31:23 +0000264- Bug #532646: object.__call__() will continue looking for the __call__
265 attribute on objects until one without one is found. This leads to recursion
266 when you take a class and set its __call__ attribute to an instance of the
267 class. Originally fixed for classic classes, but this fix is for new-style.
268 Removes the infinite_rec_3 crasher.
269
Georg Brandl24250812006-06-09 18:45:48 +0000270- The string and unicode methods startswith() and endswith() now accept
271 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
272
Brett Cannonde3b0522006-06-08 17:00:45 +0000273- Buffer objects, at the C level, never used the char buffer
274 implementation even when the char buffer for the wrapped object was
275 explicitly requested (originally returned the read or write buffer).
276 Now a TypeError is raised if the char buffer is not present but is
277 requested.
278
Georg Brandlddbaa662006-06-04 21:56:52 +0000279- Patch #1346214: Statements like "if 0: suite" are now again optimized
280 away like they were in Python 2.4.
281
Georg Brandlb7c8f542006-05-27 12:30:25 +0000282- Builtin exceptions are now full-blown new-style classes instead of
283 instances pretending to be classes, which speeds up exception handling
284 by about 80% in comparison to 2.5a2.
285
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000286- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
287 Unicode 4.1.
288
Georg Brandlf4ef1162006-05-26 18:03:31 +0000289- Patch #921466: sys.path_importer_cache is now used to cache valid and
290 invalid file paths for the built-in import machinery which leads to
291 fewer open calls on startup.
292
Tim Peters696cf432006-05-24 21:10:40 +0000293- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
294 of-2 bases. The largest speedup is for inputs with about 1000 decimal
295 digits. Conversion from non-power-of-2 bases remains quadratic-time in
296 the number of input digits (it was and remains linear-time for bases
297 2, 4, 8, 16 and 32).
298
Tim Petersb713ec22006-05-23 18:45:30 +0000299- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
300 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
301 an integer close to ``sys.maxint``. This was repaired by patch
302 #1335972, which also gives a nice speedup.
303
Richard Jonescebbefc2006-05-23 18:28:17 +0000304- Patch #1337051: reduced size of frame objects.
305
306- PyErr_NewException now accepts a tuple of base classes as its
307 "base" parameter.
308
Richard Jones7c88dcc2006-05-23 10:37:38 +0000309- Patch #876206: function call speedup by retaining allocated frame
310 objects.
311
Georg Brandl7b90e162006-05-18 07:01:27 +0000312- Bug #1462152: file() now checks more thoroughly for invalid mode
313 strings and removes a possible "U" before passing the mode to the
314 C library function.
315
Neal Norwitz1004a532006-05-15 07:17:23 +0000316- Patch #1488312, Fix memory alignment problem on SPARC in unicode
317
Neal Norwitz373f0a72006-05-15 07:04:36 +0000318- Bug #1487966: Fix SystemError with conditional expression in assignment
319
Martin v. Löwis879768d2006-05-11 13:28:43 +0000320- WindowsError now has two error code attributes: errno, which carries
321 the error values from errno.h, and winerror, which carries the error
322 values from winerror.h. Previous versions put the winerror.h values
323 (from GetLastError()) into the errno attribute.
324
Martin v. Löwis77736712006-05-04 05:51:03 +0000325- Patch #1475845: Raise IndentationError for unexpected indent.
326
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000327- Patch #1479181: split open() and file() from being aliases for each other.
328
Tim Peters44bd9862006-06-01 13:49:23 +0000329- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
330 methods were always silently ignored by dictionaries when comparing keys.
331 They are now passed through (except when using the C API function
332 ``PyDict_GetItem()``, whose semantics did not change).
333
334- Bug #1456209: In some obscure cases it was possible for a class with a
335 custom ``__eq__()`` method to confuse dict internals when class instances
336 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
337 No, you don't have any code that did this ;-)

340-----------------
341
Trent Mick960a3f82006-06-28 20:30:41 +0000342- Bug #1295808: expat symbols should be namespaced in pyexpat
343
344- Patch #1462338: Upgrade pyexpat to expat 2.0.0
345
Brett Cannon6ee7d012006-06-08 16:23:04 +0000346- Change binascii.hexlify to accept a read-only buffer instead of only a char
347 buffer and actually follow its documentation.
348
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000349- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
350
Nick Coghlanc649ec52006-05-29 12:43:05 +0000351- Patch #1478788 (modified version): The functional extension module has
352 been renamed to _functools and a functools Python wrapper module added.
353 This provides a home for additional function related utilities that are
354 not specifically about functional programming. See PEP 309.
355
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000356- Patch #1493701: performance enhancements for struct module.
357
Georg Brandl378d5922006-05-17 14:26:50 +0000358- Patch #1490224: time.altzone is now set correctly on Cygwin.
359
Georg Brandl8d3342b2006-05-16 07:38:27 +0000360- Patch #1435422: zlib's compress and decompress objects now have a
361 copy() method.
362
Andrew MacIntyre92913322006-06-13 15:04:24 +0000363- Patch #1454481: thread stack size is now tunable at runtime for thread
364 enabled builds on Windows and systems with Posix threads support.
365
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000366- On Win32, os.listdir now supports arbitrarily-long Unicode path names
367 (up to the system limit of 32K characters).
368
369- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
370 As a result, these functions now raise WindowsError instead of OSError.
371
Tim Peters7a822da2006-05-25 21:50:17 +0000372- ``time.clock()`` on Win64 should use the high-performance Windows
373 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
374 Windows platforms).
375
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000376- Calling Tk_Init twice is refused if the first call failed as that
377 may deadlock.
378
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000379- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
380 accept it without potentially using an uninitialized pointer.
381
382- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
383 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
384 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000385
Gregory P. Smith372b5832006-06-05 18:48:21 +0000386- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000387 [pybsddb project SF patch number 1466734]
388
Gregory P. Smith372b5832006-06-05 18:48:21 +0000389- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
390 parameter is supplied. [SF pybsddb bug #1477863]
391
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000392- bsddb: the __len__ method of a DB object has been fixed to return correct
393 results. It could previously incorrectly return 0 in some cases.
394 Fixes SF bug 1493322 (pybsddb bug 1184012).
395
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000396- bsddb: the bsddb.dbtables Modify method now raises the proper error and
397 aborts the db transaction safely when a modifier callback fails.
398 Fixes SF python patch/bug #1408584.
399
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000400- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000401 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000402 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
403 database calls that would previously deadlock. [SF python bug #775414]
404
Vinay Sajip28e57612006-07-01 10:45:20 +0000405- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000406
Walter Dörwald4994d952006-06-19 08:07:50 +0000407- Patch #1506645: add Python wrappers for the curses functions
408 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000409

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000413- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
414 functions.
415
Martin v. Löwis3798da02006-06-17 18:44:27 +0000416- Patch #812986: Update turtle output even if not tracing.
417
Vinay Sajip28e57612006-07-01 10:45:20 +0000418- Patch #1494750: Destroy master after deleting children in

420
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000421- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
422
Martin v. Löwis337487e2006-06-17 09:15:14 +0000423- Patch #763580: Add name and value arguments to Tkinter variable
424 classes.
425
Georg Brandl83cc0d02006-06-14 08:50:03 +0000426- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
427 mime.types file for determining MIME types.
428
Georg Brandl2605ca82006-06-14 06:08:31 +0000429- Bug #1339007: Shelf objects now don't raise an exception in their
430 __del__ method when initialization failed.
431
Martin v. Löwisd8251432006-06-14 05:21:04 +0000432- Patch #1455898: The MBCS codec now supports the incremental mode for
433 double-byte encodings.
434
Tim Peters43898b42006-06-14 04:09:25 +0000435- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
436 guarantee that adjacent triples in the return list always describe
437 non-adjacent blocks. Previously, a pair of matching blocks could end
438 up being described by multiple adjacent triples that formed a partition
439 of the matching pair.
440
Greg Ward0e0c9f42006-06-11 16:24:11 +0000441- Bug #1498146: fix optparse to handle Unicode strings in option help,
442 description, and epilog.
443
Greg Wardd1c797e2006-06-11 14:42:41 +0000444- Bug #1366250: minor optparse documentation error.
445
Greg Ward7f547402006-06-11 00:40:49 +0000446- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
447 clarify docs.
448
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000449- The wsgiref package has been added to the standard library.
450
Nick Coghlan676725d2006-06-08 13:54:49 +0000451- The functions update_wrapper() and wraps() have been added to the functools
452 module. These make it easier to copy relevant metadata from the original
453 function when writing wrapper functions.
454
Tim Petersd6a9eef2006-06-05 01:48:21 +0000455- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
456 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000457
Martin v. Löwis3f767792006-06-04 19:36:28 +0000458- Patch #1359618: Speed up charmap encoder by using a trie structure
459 for lookup.
460
Tim Petersd609b1a2006-06-02 23:22:51 +0000461- The functions in the ``pprint`` module now sort dictionaries by key
462 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
463 if and only if its display required more than one line, although that
464 wasn't documented. The new behavior increases predictability; e.g.,
465 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
466
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000467- Patch #1497027: try HTTP digest auth before basic auth in urllib2
468 (thanks for J. J. Lee).
469
Georg Brandl2b330372006-05-28 20:23:12 +0000470- Patch #1496206: improve urllib2 handling of passwords with respect to
471 default HTTP and HTTPS ports.
472
George Yoshidaf3c65de2006-05-28 16:39:09 +0000473- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
474
Bob Ippolito7298f272006-05-23 18:43:47 +0000475- Patch #1281707: speed up gzip.readline.
476
Georg Brandlb89316f2006-05-17 15:51:16 +0000477- Patch #1180296: Two new functions were added to the locale module:
478 format_string() to get the effect of "format % items" but locale-aware,
479 and currency() to format a monetary number with currency sign.
480
Georg Brandle3a25832006-05-17 14:56:04 +0000481- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
482 and several features added, such as speed and geometry control.
483
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000484- Patch #1488881: add support for external file objects in bz2 compressed
485 tarfiles.
486
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000487- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
488 stdout arguments, making it possible to redirect input and output
489 for remote debugging.
490
491- Patch #1484695: Update the tarfile module to version 0.8. This fixes
492 a couple of issues, notably handling of long file names using the
493 GNU LONGNAME extension.
494
495- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
496 new flag when ``name`` is already the name of an option flag.
497
498- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
499 package.
500
501- Patch #1472854: make the rlcompleter.Completer class usable on non-
502 UNIX platforms.
503
504- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
505
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000506- Bug #1472827: correctly escape newlines and tabs in attribute values in

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000537What's New in Python 2.5 alpha 2?
538=================================
539
540*Release date: 27-APR-2006*
541
542Core and builtins
543-----------------
544
Thomas Heller1b046642006-04-18 18:51:06 +0000545- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
546 by converting these apis from macros into exported functions again:
547
548 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
549 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
550 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
551 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
552 PyRun_String Py_CompileString
553
Martin v. Löwis45294a92006-04-18 06:24:08 +0000554- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
555
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000556- All uses of PyStructSequence_InitType have been changed to initialize
557 the type objects only once, even if the interpreter is initialized
558 multiple times.
559
Neal Norwitz61546162006-04-14 05:20:28 +0000560- Bug #1454485, array.array('u') could crash the interpreter. This was
561 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
562 to unicode when it didn't make sense. 'u#' now requires a unicode string.
563
564- Py_UNICODE is unsigned. It was always documented as unsigned, but
565 due to a bug had a signed value in previous versions.
566
Tim Peters3a5e8b12006-04-11 01:44:07 +0000567- Patch #837242: ``id()`` of any Python object always gives a positive
568 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
569 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000570 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000571 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000572
Tim Peters3a5e8b12006-04-11 01:44:07 +0000573 def __hash__(self):
574 return id(self) # WRONG
575
576 because a hash result must be a (short) Python int but it was always
577 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000578 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000579 was always usable as a hash value before this patch. That's no longer
580 necessarily so.
581
582- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000583 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000584 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000585 #1454844)
586
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000587- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
588 involving generators that have paused outside of any ``try`` or ``with``
589 blocks. (In 2.5a1, a paused generator that was part of a reference
590 cycle could not be garbage collected, regardless of whether it was
591 paused in a ``try`` or ``with`` block.)

600 fails with an error condition.
601
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000602- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
603
604- Bug #1117761: bsddb.*open() no longer raises an exception when using
605 the cachesize parameter.
606
607- Bug #1149413: bsddb.*open() no longer raises an exception when using
608 a temporary db (file=None) with the 'n' flag to truncate on open.
609
610- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
611 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000612
Armin Rigoa9017c32006-04-19 11:50:27 +0000613- Patch #1062014: AF_UNIX sockets under Linux have a special
614 abstract namespace that is now fully supported.

617-------
618
Peter Astrand7d1d4362006-07-14 14:04:45 +0000619- Bug #1223937: subprocess.CalledProcessError reports the exit status
620 of the process using the returncode attribute, instead of
621 abusing errno.
622
Tim Peters711bf302006-04-25 03:31:36 +0000623- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
624 a doctest to be skipped (the code is not run, and the expected output
625 or exception is ignored).
626
Nick Coghlanda2268f2006-04-24 04:37:15 +0000627- Fixed contextlib.nested to cope with exceptions being raised and
628 caught inside exit handlers.
629
Greg Wardab05edc2006-04-23 03:47:58 +0000630- Updated optparse module to Optik 1.5.1 (allow numeric constants in
631 hex, octal, or binary; add ``append_const`` action; keep going if
632 gettext cannot be imported; added ``OptionParser.destroy()`` method;
633 added ``epilog`` for better help generation).
634
Tim Peters21fbd572006-04-21 21:18:10 +0000635- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
636 called from a thread spawned as a side effect of importing a module.
637
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000638- The pydoc module now supports documenting packages contained in
639 .zip or .egg files.
640
641- The pkgutil module now has several new utility functions, such
642 as ``walk_packages()`` to support working with packages that are either
643 in the filesystem or zip files.
644
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000645- The mailbox module can now modify and delete messages from
646 mailboxes, in addition to simply reading them. Thanks to Gregory
647 K. Johnson for writing the code, and to the 2005 Google Summer of
648 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000649
Tim Petersc7605f22006-04-17 21:12:33 +0000650- The ``__del__`` method of class ``local`` in module ``_threading_local``
651 returned before accomplishing any of its intended cleanup.
652

Anthony Baxtere29002c2006-04-12 12:07:31 +0000659- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
660 Windows. Bug #1469163.
661
Phillip J. Eby47032112006-04-11 01:07:43 +0000662- The warnings, linecache, inspect, traceback, site, and doctest modules
663 were updated to work correctly with modules imported from zipfiles or
664 via other PEP 302 __loader__ objects.
665
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000666- Patch #1467770: Reduce usage of subprocess._active to processes which
667 the application hasn't waited on.
668
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000669- Patch #1462222: Fix Tix.Grid.
670
Neal Norwitza31bf182006-04-09 03:35:43 +0000671- Fix exception when doing glob.glob('anything*/')
672
Skip Montanaro262fb922006-04-21 02:31:07 +0000673- The pstats.Stats class accepts an optional stream keyword argument to
674 direct output to an alternate file-like object.
675
Anthony Baxter51bcb682006-04-05 14:51:42 +0000676Build
677-----
678
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000679- The Makefile now has a reindent target, which runs reindent.py on
680 the library.
681
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000682- Patch #1470875: Building Python with MS Free Compiler
683
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000684- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000685
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000686- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
687 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000688 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000689 CXX from --with-cxx-main, see description in README.
690
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000691- Patch #1429775: Link extension modules with the shared libpython.
692
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000693- Fixed a libffi build problem on MIPS systems.
694
Tim Peters8931ff12006-05-13 23:28:20 +0000695- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
696 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
697 and "%zu" for unsigned integers of type ``size_t``.
698
Anthony Baxter51bcb682006-04-05 14:51:42 +0000699Tests
700-----
701
Nick Coghlanda2268f2006-04-24 04:37:15 +0000702- test_contextlib now checks contextlib.nested can cope with exceptions
703 being raised and caught inside exit handlers.
704
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000705- test_cmd_line now checks operation of the -m and -c command switches
706
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000707- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
708 it separately and by hand. It also wasn't cleaning up its changes to
709 the current Decimal context.
710
Thomas Woutersabd08882006-04-26 15:53:30 +0000711- regrtest.py now has a -M option to run tests that test the new limits of
712 containers, on 64-bit architectures. Running these tests is only sensible
713 on 64-bit machines with more than two gigabytes of memory. The argument
714 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000722Documentation
723-------------
724
Tim Petersb06d28c2006-05-12 01:57:59 +0000725- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
726
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000727- PEP 343: Added Context Types section to the library reference
728 and attempted to bring other PEP 343 related documentation into
729 line with the implementation and/or python-dev discussions.
730
Tim Peters8dc73d22006-04-24 02:03:16 +0000731- Bug #1337990: clarified that ``doctest`` does not support examples
732 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000735What's New in Python 2.5 alpha 1?
736=================================
737
Anthony Baxterebed3f62006-04-03 15:03:44 +0000738*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000739
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000740Core and builtins
741-----------------
742
Nick Coghlan43832302006-04-23 17:04:07 +0000743- PEP 338: -m command line switch now delegates to runpy.run_module
744 allowing it to support modules in packages and zipfiles
745
Martin v. Löwisc661b882006-04-20 04:54:23 +0000746- On Windows, .DLL is not an accepted file name extension for
747 extension modules anymore; extensions are only found if they
748 end in .PYD.
749
Martin v. Löwisea62d252006-04-03 10:56:49 +0000750- Bug #1421664: sys.stderr.encoding is now set to the same value as
751 sys.stdout.encoding.
752
Neal Norwitz92e212f2006-04-03 04:48:37 +0000753- __import__ accepts keyword arguments.
754
Georg Brandlccadf842006-03-31 18:54:53 +0000755- Patch #1460496: round() now accepts keyword arguments.
756
Anthony Baxter262c00a2006-03-30 10:53:17 +0000757- Fixed bug #1459029 - unicode reprs were double-escaped.
758
Hye-Shik Changd478f342006-03-23 12:32:36 +0000759- Patch #1396919: The system scope threads are reenabled on FreeBSD
760 5.4 and later versions.
761
Neal Norwitze98ccf62006-03-23 05:39:47 +0000762- Bug #1115379: Compiling a Unicode string with an encoding declaration
763 now gives a SyntaxError.
764
Georg Brandlabd1ff82006-03-18 07:59:59 +0000765- Previously, Python code had no easy way to access the contents of a
766 cell object. Now, a ``cell_contents`` attribute has been added
767 (closes patch #1170323).
768
Tim Peterscf79aac2006-03-16 01:14:46 +0000769- Patch #1123430: Python's small-object allocator now returns an arena to
770 the system ``free()`` when all memory within an arena becomes unused
771 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
772 freed. Some applications will see a drop in virtual memory size now,
773 especially long-running applications that, from time to time, temporarily
774 use a large number of small objects. Note that when Python returns an
775 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000776 platform C library will in turn return that memory to the operating system.
777 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000778 appears to be effective at least on Microsoft C and gcc-based systems.
779 Thanks to Evan Jones for hard work and patience.
780
Georg Brandl533ff6f2006-03-08 18:09:27 +0000781- Patch #1434038: property() now uses the getter's docstring if there is
782 no "doc" argument given. This makes it possible to legitimately use
783 property() as a decorator to produce a read-only property.
784
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000785- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
786 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
787 of requiring an int or long in slicing and a few other contexts, enabling
788 other objects (e.g. Numeric Python's integers) to be used as slice indices.
789
Neal Norwitz995acdf2006-03-07 05:01:00 +0000790- Fixed various bugs reported by Coverity's Prevent tool.
791
Brett Cannonbf364092006-03-01 04:25:17 +0000792- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
793 new exception base class, BaseException, which has a new message attribute.
794 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
795 Raising a string exception now raises a DeprecationWarning.
796
Thomas Woutersfb609f42006-02-28 16:37:25 +0000797- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
798 explicitly relative, using 'from .module import name' to mean 'from the same
799 package as this module is in. Imports without dots still default to the
800 old relative-then-absolute, unless 'from __future__ import
801 absolute_import' is used.
802
Brett Cannona7446e32006-02-27 23:39:10 +0000803- Properly check if 'warnings' raises an exception (usually when a filter set
804 to "error" is triggered) when raising a warning for raising string
805 exceptions.
806
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000807- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000808 The name was removed from Include/code.h.
809
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000810- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000811
Guido van Rossum1968ad32006-02-25 22:38:04 +0000812- Patch 1433928:
813 - The copy module now "copies" function objects (as atomic objects).
814 - dict.__getitem__ now looks for a __missing__ hook before raising
815 KeyError.
816
Tim Peters84ef21c2006-02-28 20:39:06 +0000817- PEP 343: with statement implemented. Needs ``from __future__ import
818 with_statement``. Use of 'with' as a variable will generate a warning.
819 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000820 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000821 The following objects have __context__ methods:
822 - The built-in file type.
823 - The thread.LockType type.
824 - The following types defined by the threading module:
825 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
826 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000827
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000828- Fix the encodings package codec search function to only search
829 inside its own package. Fixes problem reported in patch #1433198.
830
831 Note: Codec packages should implement and register their own
832 codec search function. PEP 100 has the details.
833
Tim Peters9ea89d22006-06-04 03:26:02 +0000834- PEP 353: Using ``Py_ssize_t`` as the index type.
835
836- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
837 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
838 now allow Python to make use of memory blocks exceeding 2**32 bytes for
839 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
840 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000841
Neal Norwitzfc76d632006-01-10 06:03:13 +0000842- Patch #1400181, fix unicode string formatting to not use the locale.
843 This is how string objects work. u'%f' could use , instead of .
844 for the decimal point. Now both strings and unicode always use periods.
845
Neal Norwitz671b9e32006-01-09 07:07:12 +0000846- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
847 configure would break checking curses.h.
848
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000849- Bug #959576: The pwd module is now builtin. This allows Python to be
850 built on UNIX platforms without $HOME set.
851
Neal Norwitzc10978f2005-12-19 06:07:16 +0000852- Bug #1072182, fix some potential problems if characters are signed.
853
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000854- Bug #889500, fix line number on SyntaxWarning for global declarations.
855
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000856- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
857
Neal Norwitze7214a12005-12-18 05:03:17 +0000858- Support for converting hex strings to floats no longer works.
859 This was not portable. float('0x3') now raises a ValueError.
860
Barry Warsaw2a38a862005-12-18 01:27:35 +0000861- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000862 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000863 is now displayed in interactive prompt banner.
864
Georg Brandlfa166682005-12-17 21:45:17 +0000865- Implementation of PEP 341 - Unification of try/except and try/finally.
866 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000867 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000868
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000869- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
870 now encodes backslash correctly.
871
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000872- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
873
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000874- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000875 and long longs.
876
Neal Norwitz67715f02005-11-09 06:59:35 +0000877- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000878 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000879 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000880
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000881- Replaced most Unicode charmap codecs with new ones using the
882 new Unicode translate string feature in the builtin charmap
883 codec; the codecs were created from the mapping tables available
884 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
885 encodings now include a mapping for the Apple logo)
886
Tim Peterse3547fd2005-12-16 23:13:57 +0000887- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000888
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000889- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000890
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000891- A new AST parser implementation was completed. The abstract
892 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000893 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000894
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000895- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000896 The following code now raises a SyntaxError: foo(a = i for i in range(10))
897
Neal Norwitz708e51a2005-10-03 04:48:15 +0000898- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
899
Neal Norwitz11bd1192005-10-03 00:54:56 +0000900- SF Bug #887946: fix segfault when redirecting stdin from a directory.
901 Provide a warning when a directory is passed on the command line.
902
Neal Norwitz40d37812005-10-02 01:48:49 +0000903- Fix segfault with invalid coding.
904
905- SF bug #772896: unknown encoding results in MemoryError.
906
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000907- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000908 supported a __len__() method which evaluated to False when the iterator
909 was empty.
910
Guido van Rossum630db602005-09-20 18:49:54 +0000911- On 64-bit platforms, when __len__() returns a value that cannot be
912 represented as a C int, raise OverflowError.
913
Skip Montanarof8948ca2005-09-19 03:54:46 +0000914- test__locale is skipped on OS X < 10.4 (only partial locale support is

Georg Brandl80bbf3f2005-09-14 19:38:29 +0000917- SF bug #893549: parsing keyword arguments was broken with a few format
918 codes.
919
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000920- Changes donated by Elemental Security to make it work on AIX 5.3
921 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
922 bug #105470: test_pwd fails on 64bit system (Opteron).
923
Guido van Rossum539c6622005-09-14 17:49:54 +0000924- Changes donated by Elemental Security to make it work on HP-UX 11 on
925 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
926
Georg Brandl4550b8d2005-08-26 06:43:52 +0000927- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000928 (fixes bug #1119418).
929
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000930- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
931
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000932- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
933 exceptions that cause a function to exit.
934
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000935- The implementation of set() and frozenset() was revised to use its
936 own internal data structure. Memory consumption is reduced by 1/3
937 and there are modest speed-ups as well. The API is unchanged.
938
Tim Petersde7990b2005-07-17 23:45:23 +0000939- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
940
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000941- SF bug #1229429: PyObject_CallMethod failed to decrement some
942 reference counts in some error exit cases.
943
Tim Petersecc6e6a2005-07-10 22:30:55 +0000944- SF bug #1185883: Python's small-object memory allocator took over
945 a block managed by the platform C library whenever a realloc specified
946 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000947 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000948 portable way to copy data from the C-managed block into Python's
949 small-object space without risking a memory fault. Python's small-object
950 realloc now leaves such blocks under the control of the platform C
951 realloc.
952
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000953- SF bug #1232517: An overflow error was not detected properly when
954 attempting to convert a large float to an int in os.utime().
955
Raymond Hettinger3296e692005-06-29 23:29:56 +0000956- SF bug #1224347: hex longs now print with lowercase letters just
957 like their int counterparts.
958
Michael W. Hudson188d4362005-06-20 16:52:57 +0000959- SF bug #1163563: the original fix for bug #1010677 ("thread Module
960 Breaks PyGILState_Ensure()") broke badly in the case of multiple
961 interpreter states; back out that fix and do a better job (see
962 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
963 for a longer write-up of the problem).
964
Michael W. Hudsondf888462005-06-03 14:41:55 +0000965- SF patch #1180995: marshal now uses a binary format by default when
966 serializing floats.
967
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000968- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
969 the routines that promise to produce IEEE 754 binary representations
970 of floats now simply copy bytes around.
971
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000972- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
973 278.
974
Brett Cannonc3647ac2005-04-26 03:45:26 +0000975- patch #1109424: int, long, float, complex, and unicode now check for the
976 proper magic slot for type conversions when subclassed. Previously the
977 magic slot was ignored during conversion. Semantics now match the way
978 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000979 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000980 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000981 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000982
Barry Warsawc8d907c2005-04-19 23:43:40 +0000983- Descriptors defined in C with a PyGetSetDef structure, where the setter is
984 NULL, now raise an AttributeError when attempting to set or delete the
985 attribute. Previously a TypeError was raised, but this was inconsistent
986 with the equivalent pure-Python implementation.
987
Michael W. Hudson774479c2005-04-18 08:46:17 +0000988- It is now safe to call PyGILState_Release() before
989 PyEval_InitThreads() (note that if there is reason to believe there
990 are multiple threads around you still must call PyEval_InitThreads()
991 before using the Python API; this fix is for extension modules that
992 have no way of knowing if Python is multi-threaded yet).
993
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000994- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
995 disabled caused a crash.
996
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000997- Bug #1165306: instancemethod_new allowed the creation of a method
998 with im_class == im_self == NULL, which caused a crash when called.
999
Tim Petersecc6e6a2005-07-10 22:30:55 +00001000- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001001 fixes the crash seen in bug #1165761
1002
Raymond Hettinger96229b12005-03-11 06:49:40 +00001003- Added two new builtins, any() and all().
1004
Brett Cannon409d8f22005-03-05 06:47:57 +00001005- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001006 (e.g., ``class C(): pass`` is no longer a syntax error).
1007 Patch #1176012 added support to the 'parser' module and 'compiler' package
1008 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001009
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001010- Patch #1115086: Support PY_LONGLONG in structmember.
1011
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001012- Bug #1155938: new style classes did not check that __init__() was
1013 returning None.
1014
Tim Petersecc6e6a2005-07-10 22:30:55 +00001015- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001016 ('\') with a specific error message.
1017
Martin v. Löwisff232d72005-03-03 09:24:38 +00001018- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1019
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001020- Bug #1124295: the __name__ attribute of file objects was
1021 inadvertently made inaccessible in restricted mode.
1022
Tim Petersecc6e6a2005-07-10 22:30:55 +00001023- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001024 an ferror() call.
1025
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001026- min() and max() now support key= arguments with the same meaning as in
1027 list.sort().
1028
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001029- The peephole optimizer now performs simple constant folding in expressions:
1030 (2+3) --> (5).
1031
Raymond Hettingera422c342005-01-11 03:03:27 +00001032- set and frozenset objects can now be marshalled. SF #1098985.
1033
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001034- Bug #1077106: Poor argument checking could cause memory corruption
1035 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001036
Jeremy Hyltonab630502005-02-04 18:44:06 +00001037- The parser did not complain about future statements in illegal
1038 positions. It once again reports a syntax error if a future
1039 statement occurs after anything other than a doc string.
1040
Neil Schemenauercf52c072005-08-12 17:34:58 +00001041- Change the %s format specifier for str objects so that it returns a
1042 unicode instance if the argument is not an instance of basestring and
1043 calling __str__ on the argument returns a unicode instance.
1044
Tim Petersf4e69282006-02-27 17:15:31 +00001045- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1046 current thread state when the auto-GIL-state machinery knows about
1047 it (since the thread state is being deleted, continuing to remember it
1048 can't help, but can hurt if another thread happens to get created with
1049 the same thread id).

1076
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001077- The unicodedata module was updated to the 4.1 version of the Unicode
1078 database. The 3.2 version is still available as unicodedata.db_3_2_0
1079 for applications that require this specific version (such as IDNA).
1080
Neal Norwitzb62c4332006-03-04 18:35:47 +00001081- The timing module is no longer built by default. It was deprecated
1082 in PEP 4 in Python 2.0 or earlier.
1083
Guido van Rossum1968ad32006-02-25 22:38:04 +00001084- Patch 1433928: Added a new type, defaultdict, to the collections module.
1085 This uses the new __missing__ hook behavior added to dict (see above).
1086
Georg Brandldbd83392006-02-20 09:42:33 +00001087- Bug #854823: socketmodule now builds on Sun platforms even when

1097 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1098 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1099
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001100- Patch #1422385: The nis module now supports access to domains other
1101 than the system default domain.
1102
Martin v. Löwis14694662006-02-03 12:54:16 +00001103- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1104 are reported, the limit on path name lengths is removed, and stat reports
1105 WindowsError now (instead of OSError).
1106
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001107- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

1182 the request code argument, which results in more C-like behaviour
1183 for large or negative values.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001241- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1242 been renamed to have only a single underscore prefix. This was done to
1243 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001244
Nick Coghlan43832302006-04-23 17:04:07 +00001245- PEP 338: new module runpy defines a run_module function to support
1246 executing modules which provide access to source code or a code object
1247 via the PEP 302 import mechanisms.
1248
Anthony Baxter93f5b932006-04-03 08:05:07 +00001249- The email module's parsedate_tz function now sets the daylight savings

1257 in attribute values.
1258
Anthony Baxterc51ee692006-04-01 00:57:31 +00001259- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001260 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001261 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001262 module will not be built.
1263
Tim Petersc17976e2006-04-01 00:26:53 +00001264- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1265 aren't officially supported here, and trying to use them will probably
1266 raise an exception some day. But dicts have been allowed, and "mostly
1267 worked", so support for them won't go away without warning.
1268
Georg Brandl338ef7d2006-03-31 18:42:16 +00001269- Bug #1445068: getpass.getpass() can now be given an explicit stream
1270 argument to specify where to write the prompt.
1271

1281 to make it easier to monitor when daemon threads have completed
1282 processing all enqueued tasks. Patch #1455676.
1283

1287
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001288- email 4.0 package now integrated. This is largely the same as the email 3.0
1289 package that was included in Python 2.3, except that PEP 8 module names are
1290 now used (e.g. mail.message instead of email.Message). The MIME classes
1291 have been moved to a subpackage (e.g. email.mime.text instead of
1292 email.MIMEText). The old names are still supported for now. Several
1293 deprecated Message methods have been removed and lots of bugs have been
1294 fixed. More details can be found in the email package documentation.
1295
Walter Dörwald40108c92006-03-27 08:15:44 +00001296- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1297 (a subclass of tuple) that provides incremental decoders and encoders
1298 (a way to use stateful codecs without the stream API). Python functions
1299 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1300 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1301 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001302
Walter Dörwald067db482006-03-15 22:17:27 +00001303- Patch #1359365: Calling next() on a closed StringIO.String object raises
1304 a ValueError instead of a StopIteration now (like file and cString.String do).
1305 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1306 called before (like file and StringIO.StringIO do).

Martin v. Löwis3e865952006-01-24 15:51:21 +00001356 specifications, raises IOErrors when proxies for unsupported protocols
1357 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00001380 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1381 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1382 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1383 Ronald L. Rivest offered this advice for Python:
1384
1385 "The consensus of researchers in this area (at least as
1386 expressed at the NIST Hash Function Workshop 10/31/05),
1387 is that SHA-256 is a good choice for the time being, but
1388 that research should continue, and other alternatives may
1389 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001390
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001391- Added a subset of Fredrik Lundh's ElementTree package. Available

1462 parameter, but uses the usual "kwargs=None".
1463
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001464- textwrap now processes text chunks at O(n) speed instead of O(n**2).

1466
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00001467- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
1468 to W3C name (404 -> 'Not Found'). RFE #1216944.
1469
Georg Brandl9e43acf2005-07-04 17:16:07 +00001470- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1471 as this can cause problems with apps closing all file descriptors.
1472
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001473- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001474 it can be missing in embedded interpreters

Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001483- The tokenize module now detects and reports indentation errors.
1484 Bug #1224621.
1485
Raymond Hettinger68c04532005-06-10 11:05:19 +00001486- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001487 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001488 the generate_tokens() function now accepts a callable argument that
1489 terminates by raising StopIteration.
1490
Georg Brandl9166e1a2005-06-04 09:20:03 +00001491- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1498 to True, applications shouldn't have to fiddle with the DateTime wrapper
1499 class at all.
1500
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001501- distutils.commands.upload was added to support uploading distribution

1505 them to PyPI.
1506
Raymond Hettinger267b8682005-03-27 10:47:39 +00001507- decimal operator and comparison methods now return NotImplemented
1508 instead of raising a TypeError when interacting with other types. This
1509 allows other classes to implement __radd__ style methods and have them
1510 work as expected.
1511
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001512- Bug #1163325: Decimal infinities failed to hash. Attempting to
1513 hash a NaN raised an InvalidOperation instead of a TypeError.
1514
Tim Petersecc6e6a2005-07-10 22:30:55 +00001515- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1549
Guido van Rossumd0641422005-02-03 15:01:24 +00001550- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1551 disables recursive traversal through instance attributes, which can
1552 be exploited in various ways.
1553
Tim Peterse3547fd2005-12-16 23:13:57 +00001554- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001555 flags on the HTTP listening socket.
1556
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001557- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1558 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1559
Tim Peterse3547fd2005-12-16 23:13:57 +00001560- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001561 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1562
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001563- Bug #1110478: Revert os.environ.update to do putenv again.
1564
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001565- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1566
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001567- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1568
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001569- Enhancements to the csv module:
1570
1571 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001572 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001573 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001574 + Dialect parameter parsing has been re-implemented to improve error
1575 reporting.
1576 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1577 dictates.
1578 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001579 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001580 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001581 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1582 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001583 + reader now allows \r characters to be quoted (previously it only allowed
1584 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001585 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001586 + Dialect classes passed to the module are no longer instantiated by
1587 the module before being parsed (the former validation scheme required
1588 this, but the mechanism was unreliable).
1589 + The dialect registry now contains instances of the internal
1590 C-coded dialect type, rather than references to python objects.
1591 + the internal c-coded dialect type is now immutable.
1592 + register_dialect now accepts the same keyword dialect specifications
1593 as the reader and writer, allowing the user to register dialects
1594 without first creating a dialect class.
1595 + a configurable limit to the size of parsed fields has been added -
1596 previously, an unmatched quote character could result in the entire
1597 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001598 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001599 the parser field size limit (returning the former limit). The initial
1600 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001601 + A line_num attribute has been added to the reader object, which tracks
1602 the number of lines read from the source iterator. This is not
1603 the same as the number of records returned, as records can span
1604 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001605 + reader and writer objects were not being registered with the cyclic-GC.
1606 This has been fixed.
1607
Brett Cannone6539c42005-01-08 02:43:53 +00001608- _DummyThread objects in the threading module now delete self.__block that is
1609 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1610 lock primitives tend to be limited in number and thus should not be wasted on
1611 a _DummyThread object. Fixes bug #1089632.
1612
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001613- The imghdr module now detects Exif files.
1614
Raymond Hettinger6065d322004-12-20 23:51:53 +00001615- StringIO.truncate() now correctly adjusts the size attribute.
1616 (Bug #951915).
1617
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001618- locale.py now uses an updated locale alias table (built using
1619 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1620 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001621 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001622
Raymond Hettinger3557f422004-12-07 12:02:02 +00001623- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1624
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001625- the pickle module no longer accepts the deprecated None option in the
1626 args tuple returned by __reduce__().
1627
Brett Cannon84667c02004-12-07 03:25:18 +00001628- optparse now optionally imports gettext. This allows its use in setup.py.
1629
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001630- the pickle module no longer uses the deprecated bin parameter.
1631
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001632- the shelve module no longer uses the deprecated binary parameter.
1633
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001634- the pstats module no longer uses the deprecated ignore() method.
1635
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001636- the filecmp module no longer uses the deprecated use_statcache argument.
1637
Raymond Hettinger664347b2004-12-04 21:21:53 +00001638- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1639 extended or overridden by subclasses. Formerly, the subclassed method would
1640 be ignored by the rest of the module. (Bug #1078905).
1641
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001642- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001643 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001644
Walter Dörwald36733692004-12-22 12:50:50 +00001645- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1646 once when a size argument is given. This prevents a buffer overflow in the
1647 tokenizer with very long source lines.
1648
Barry Warsaw538561e2006-01-01 21:48:54 +00001649- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1650 immediately after creating the object, without any intervening
1651 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001652
Skip Montanaro05885812005-01-16 20:48:27 +00001653- The reconvert.quote function can now emit triple-quoted strings. The
1654 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001655
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001656- ``UserString.MutableString`` now supports negative indices in
1657 ``__setitem__`` and ``__delitem__``
1658
Greg Ward40407942005-03-05 02:53:17 +00001659- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1660 correctly.
1661
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001662- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1663 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1664 character even if the user has passed a size parameter to get a proper
1665 line ending. Remove the special handling of a "\r\n" that has been split
1666 between two lines.
1667
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001668- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1669 about illegal code points. The codec now supports PEP 293 style error
1670 handlers.
1671
Walter Dörwald78a78b02005-09-01 12:04:29 +00001672- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001673 from the input stream, so that the output is a byte string in the correct
1674 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001675
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001676- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1677 considering it exactly like a '*'.
1678
Walter Dörwald007f8df2005-10-09 19:42:27 +00001679- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1680 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001681
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001682- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1683
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001684- Patch #1413711: Certain patterns of differences were making difflib
1685 touch the recursion limit.
1686
Walter Dörwald58917a62006-03-31 15:26:22 +00001687- Bug #947906: An object oriented interface has been added to the calendar
1688 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001689 called as a script (e.g. via ``python -mcalendar``). Localized month and
1690 weekday names can be ouput (even if an exotic encoding is used) using
1691 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001692

Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001705- Patch #881820: look for openpty and forkpty also in libbsd.
1706
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001707- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1708 The zlib module is now builtin on Windows.
1709
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001710- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1711
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001712- Bug #1189330: configure did not correctly determine the necessary
1713 value of LINKCC if python was built with GCC 4.0.
1714
Trent Mick8321b422005-07-26 02:29:21 +00001715- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1716 vulnerability in zlib 1.2.1 and 1.2.2.
1717
Brett Cannon08cd5982005-04-24 22:26:38 +00001718- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1719 flags that change binary compatibility. Changes were also made to
1720 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001721 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001722
Bob Ippolitoed233462005-03-29 13:47:59 +00001723- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1724 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1725 no longer exists). This configure patch makes things right.
1726
Martin v. Löwise2713be2005-03-08 15:03:08 +00001727- Bug #1158607: Build with --disable-unicode again.
1728
Brett Cannon46d96232005-02-16 00:07:19 +00001729- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1730 defined. Discovered as a result of not being able to build on OS X.
1731
Brett Cannon516592f2004-12-07 00:42:59 +00001732- setup.py now uses the directories specified in LDFLAGS using the -L option
1733 and in CPPFLAGS using the -I option for adding library and include
1734 directories, respectively, for compiling extension modules against. This has
1735 led to the core being compiled using the values in CPPFLAGS. It also removes
1736 the need for the special-casing of both DarwinPorts and Fink for darwin since
1737 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1738 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1739 Fink, ``-I/opt/local/include`` for DarwinPorts).
1740
Brett Cannon43802422005-02-10 20:48:03 +00001741- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1742 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1743 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1744 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001746C API
1747-----
1748
Tim Petersc9d78aa2006-03-26 23:27:58 +00001749- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1750 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1751 is obtained via the ``PyObject_`` family, it must be released via the
1752 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1753 always been officially true, but when Python's small-object allocator was
1754 introduced, an attempt was made to cater to a few extension modules
1755 discovered at the time that obtained memory via ``PyObject_New`` but
1756 released it via ``PyMem_DEL``. It's years later, and if such code still
1757 exists it will fail now (probably with segfaults, but calling wrong
1758 low-level memory management functions can yield many symptoms).
1759
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001760- Added a C API for set and frozenset objects.
1761

1763
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001764- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1765 mapping argument now. This string is used as a mapping table. Byte values
1766 greater than the length of the string and 0xFFFE are treated as undefined
1767 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001774
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001775- Patch #1276356: New resource "urlfetch" is implemented. This enables
1776 even impatient people to run tests that require remote files.
