Neal Norwitza1f10902006-07-12 07:28:29 +00007What's New in Python 2.5 release candidate 1?
8=============================================

10*Release date: XX-AUG-2006*
11
12Core and builtins
13-----------------
14
Neal Norwitze7563102006-07-17 01:00:16 +000015- Fix warnings reported by Klocwork's static analysis tool.
16
Neal Norwitz84be93b2006-07-16 01:50:38 +000017- Bug #1512814, Fix incorrect lineno's when code within a function
18 had more than 255 blank lines.
19
Georg Brandl9dceedb2006-07-12 15:31:17 +000020- Patch #1521179: Python now accepts the standard options ``--help`` and
21 ``--version`` as well as ``/?`` on Windows.
22
Neal Norwitza1f10902006-07-12 07:28:29 +000023- Bug #1520864: unpacking singleton tuples in for loop (for x, in) work
24 again. Fixing this problem required changing the .pyc magic number.
25 This means that .pyc files generated before 2.5c1 will be regenerated.
26
Tim Peters112aad32006-07-19 00:03:19 +000027- Bug #1524317: Compiling Python ``--without-threads`` failed.
28 The Python core compiles again then, and, in a build without threads, the
29 new ``sys._current_frames()`` returns a dictionary with one entry,
30 mapping the faux "thread id" 0 to the current frame.

33-------
34
Martin v. Löwis426f4a12006-07-18 17:46:31 +000035- Patch #1524429: Use repr() instead of backticks in Tkinter again.
36
Brett Cannoncaebe222006-07-18 04:41:36 +000037- Bug #1520914: Change time.strftime() to accept a zero for any position in its
38 argument tuple. For arguments where zero is illegal, the value is forced to
39 the minimum value that is correct. This is to support an undocumented but
40 common way people used to fill in inconsequential information in the time
41 tuple pre-2.4.
42
Bob Ippolito5ea4bf12006-07-15 16:53:15 +000043- Patch #1220874: Update the binhex module for Mach-O.
44

46-----------------
47
Thomas Hellerce049a02006-07-14 17:51:14 +000048- Patch #1521817: Index range checking on ctypes arrays containing
49 exactly one element enabled again. This allows iterating over these
50 arrays, without the need to check the array size before.
51
Thomas Heller6e1ad2e2006-07-13 17:05:13 +000052- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +000053 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +000054 /dev/null in certain cases; this is now fixed.
55
Thomas Heller47d7a062006-07-12 08:43:47 +000056- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
57 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +000058
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +000059- Because of a misspelled preprocessor symbol, ctypes was always
60 compiled without thread support; this is now fixed.

67Core and builtins
68-----------------
69
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +000070- Bug #1441486: The literal representation of -(sys.maxint - 1)
71 again evaluates to a int object, not a long.
72
Neil Schemenauer0e07b602006-07-09 16:16:34 +000073- Bug #1501934: The scope of global variables that are locally assigned
74 using augmented assignment is now correctly determined.
75
Martin v. Löwisd5cfa542006-07-03 13:47:40 +000076- Bug #927248: Recursive method-wrapper objects can now safely
77 be released.
78
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +000079- Bug #1417699: Reject locale-specific decimal point in float()
80 and atof().
81
Hye-Shik Change6a1cb92006-06-23 21:16:18 +000082- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
83 omit a default "error" argument for NULL pointer. This allows
84 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +000085
Neal Norwitzfb48afa2006-07-08 05:31:37 +000086- Bug #1519018: 'as' is now validated properly in import statements.
87
Neal Norwitz28746ab2006-07-09 22:14:42 +000088- On 64 bit systems, int literals that use less than 64 bits are
89 now ints rather than longs.
90
Neal Norwitzed657552006-07-10 00:04:44 +000091- Bug #1512814, Fix incorrect lineno's when code at module scope
92 started after line 256.
93
Tim Peters32a83612006-07-10 21:08:24 +000094- New function ``sys._current_frames()`` returns a dict mapping thread
95 id to topmost thread stack frame. This is for expert use, and is
96 especially useful for debugging application deadlocks. The functionality
97 was previously available in Fazal Majid's ``threadframe`` extension
98 module, but it wasn't possible to do this in a wholly threadsafe way from
99 an extension.
100
Georg Brandlad29e632006-06-21 17:45:17 +0000101Library

Martin v. Löwis8d656812006-07-10 07:23:48 +0000107 environment variable to be set in order to the SDK environment
108 for finding the compiler, include files, etc.
109
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000110- Bug #1515998: Properly generate logical ids for files in bdist_msi.
111
Nick Coghlan2d792252006-07-06 13:47:18 +0000112- warnings.py now ignores ImportWarning by default
113
Thomas Woutersadd19112006-07-05 11:03:49 +0000114- string.Template() now correctly handles tuple-values. Previously,
115 multi-value tuples would raise an exception and single-value tuples would
116 be treated as the value they contain, instead.
117
Martin v. Löwisede77f52006-07-03 13:01:35 +0000118- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
119 even if some data are received.
120
Martin v. Löwis45482392006-07-03 12:28:58 +0000121- Bug #1267547: Put proper recursive setup.py call into the

Martin v. Löwis2b88f632006-07-03 10:19:49 +0000128 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000129
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000130- Bug #1514703: Only setup canvas window in turtle when the canvas
131 is created.
132
Martin v. Löwis7596e832006-07-01 15:33:37 +0000133- Bug #1513223: .close() of a _socketobj now releases the underlying
134 socket again, which then gets closed as it becomes unreferenced.
135
Fred Drake10497c82006-06-29 02:57:48 +0000136- Bug #1504333: Make sgmllib support angle brackets in quoted
137 attribute values.
138
139- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
140 sgmllib ('[' and ']' were not accepted).
141
Georg Brandl1be63af2006-06-28 20:23:25 +0000142- Fix a bug in the turtle module's end_fill function.
143
Brett Cannon53ab5b72006-06-22 16:49:14 +0000144- Bug #1510580: The 'warnings' module improperly required that a Warning
145 category be either a types.ClassType and a subclass of Warning. The proper
146 check is just that it is a subclass with Warning as the documentation states.
147
Georg Brandlad29e632006-06-21 17:45:17 +0000148- The compiler module now correctly compiles the new try-except-finally
149 statement (bug #1509132).
150
Neal Norwitz60373cd2006-06-22 06:30:50 +0000151- The wsgiref package is now installed properly on Unix.
152
Vinay Sajip28e57612006-07-01 10:45:20 +0000153- A bug was fixed in logging.config.fileConfig() which caused a crash on
154 shutdown when fileConfig() was called multiple times.
155
Gerhard Häring762fbd32006-07-02 17:48:30 +0000156- The sqlite3 module did cut off data from the SQLite database at the first
157 null character before sending it to a custom converter. This has been fixed
158 now.
159
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000160Extension Modules
161-----------------
162
Tim Peters112aad32006-07-19 00:03:19 +0000163- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
164 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
165 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000166
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000167- Assigning None to pointer type fields in ctypes structures possible
168 overwrote the wrong fields, this is fixed now.
169
170- Fixed a segfault in _ctypes when ctypes.wintypes were imported
171 on non-Windows platforms.
172
173- Bug #1518190: The ctypes.c_void_p constructor now accepts any
174 integer or long, without range checking.
175
176- Patch #1517790: It is now possible to use custom objects in the ctypes
177 foreign function argtypes sequence as long as they provide a from_param
178 method, no longer is it required that the object is a ctypes type.
179
180- The '_ctypes' extension module now works when Python is configured
181 with the --without-threads option.
182
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000183- Bug #1513646: os.access on Windows now correctly determines write
184 access, again.
185
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000186- Bug #1512695: cPickle.loads could crash if it was interrupted with
187 a KeyboardInterrupt.
188
Neal Norwitza12aa882006-07-06 06:45:08 +0000189- Bug #1296433: parsing XML with a non-default encoding and
190 a CharacterDataHandler could crash the interpreter in pyexpat.
191
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000192- Patch #1516912: improve Modules support for OpenVMS.
193
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000194Build
195-----
196
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000197- Automate Windows build process for the Win64 SSL module.
198
Tim Peters32a83612006-07-10 21:08:24 +0000199- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000200 Previously, the slight difference could cause compilation errors of the
201 'zlib' module on systems with more than one version of zlib.
202
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000203- The MSI compileall step was fixed to also support a TARGETDIR
204 with spaces in it.
205
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000206- Bug #1517388: sqlite3.dll is now installed on Windows independent
207 of Tcl/Tk.
208
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000209- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000210 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +0000211
Neal Norwitzb15ac312006-06-29 04:10:08 +0000212Tests
213-----
214
215- Call os.waitpid() at the end of tests that spawn child processes in order
216 to minimize resources (zombies).
217
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000218Documentation
219-------------
220
Nick Coghlan2d792252006-07-06 13:47:18 +0000221- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
222 documentation for the warnings module.
223

Nick Coghlanc649ec52006-05-29 12:43:05 +0000228What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +0000229================================
Anthony Baxter51bcb682006-04-05 14:51:42 +0000230
Anthony Baxterd1136802006-06-19 12:04:15 +0000231*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000232
233Core and builtins
234-----------------
235
Georg Brandla56b9152006-06-19 06:35:54 +0000236- Patch #1507676: Error messages returned by invalid abstract object operations
237 (such as iterating over an integer) have been improved and now include the
238 type of the offending object to help with debugging.
239
Brett Cannonea3912b2006-06-13 21:46:41 +0000240- Bug #992017: A classic class that defined a __coerce__() method that returned
241 its arguments swapped would infinitely recurse and segfault the interpreter.
242
Neal Norwitz909eb122006-06-12 02:13:21 +0000243- Fix the socket tests so they can be run concurrently.
244
Neal Norwitzb9845e72006-06-12 02:11:18 +0000245- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000246 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000247
Brett Cannon22565aa2006-06-09 22:31:23 +0000248- Bug #532646: object.__call__() will continue looking for the __call__
249 attribute on objects until one without one is found. This leads to recursion
250 when you take a class and set its __call__ attribute to an instance of the
251 class. Originally fixed for classic classes, but this fix is for new-style.
252 Removes the infinite_rec_3 crasher.
253
Georg Brandl24250812006-06-09 18:45:48 +0000254- The string and unicode methods startswith() and endswith() now accept
255 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
256
Brett Cannonde3b0522006-06-08 17:00:45 +0000257- Buffer objects, at the C level, never used the char buffer
258 implementation even when the char buffer for the wrapped object was
259 explicitly requested (originally returned the read or write buffer).
260 Now a TypeError is raised if the char buffer is not present but is
261 requested.
262
Georg Brandlddbaa662006-06-04 21:56:52 +0000263- Patch #1346214: Statements like "if 0: suite" are now again optimized
264 away like they were in Python 2.4.
265
Georg Brandlb7c8f542006-05-27 12:30:25 +0000266- Builtin exceptions are now full-blown new-style classes instead of
267 instances pretending to be classes, which speeds up exception handling
268 by about 80% in comparison to 2.5a2.
269
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000270- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
271 Unicode 4.1.
272
Georg Brandlf4ef1162006-05-26 18:03:31 +0000273- Patch #921466: sys.path_importer_cache is now used to cache valid and
274 invalid file paths for the built-in import machinery which leads to
275 fewer open calls on startup.
276
Tim Peters696cf432006-05-24 21:10:40 +0000277- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
278 of-2 bases. The largest speedup is for inputs with about 1000 decimal
279 digits. Conversion from non-power-of-2 bases remains quadratic-time in
280 the number of input digits (it was and remains linear-time for bases
281 2, 4, 8, 16 and 32).
282
Tim Petersb713ec22006-05-23 18:45:30 +0000283- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
284 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
285 an integer close to ``sys.maxint``. This was repaired by patch
286 #1335972, which also gives a nice speedup.
287
Richard Jonescebbefc2006-05-23 18:28:17 +0000288- Patch #1337051: reduced size of frame objects.
289
290- PyErr_NewException now accepts a tuple of base classes as its
291 "base" parameter.
292
Richard Jones7c88dcc2006-05-23 10:37:38 +0000293- Patch #876206: function call speedup by retaining allocated frame
294 objects.
295
Georg Brandl7b90e162006-05-18 07:01:27 +0000296- Bug #1462152: file() now checks more thoroughly for invalid mode
297 strings and removes a possible "U" before passing the mode to the
298 C library function.
299
Neal Norwitz1004a532006-05-15 07:17:23 +0000300- Patch #1488312, Fix memory alignment problem on SPARC in unicode
301
Neal Norwitz373f0a72006-05-15 07:04:36 +0000302- Bug #1487966: Fix SystemError with conditional expression in assignment
303
Martin v. Löwis879768d2006-05-11 13:28:43 +0000304- WindowsError now has two error code attributes: errno, which carries
305 the error values from errno.h, and winerror, which carries the error
306 values from winerror.h. Previous versions put the winerror.h values
307 (from GetLastError()) into the errno attribute.
308
Martin v. Löwis77736712006-05-04 05:51:03 +0000309- Patch #1475845: Raise IndentationError for unexpected indent.
310
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000311- Patch #1479181: split open() and file() from being aliases for each other.
312
Tim Peters44bd9862006-06-01 13:49:23 +0000313- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
314 methods were always silently ignored by dictionaries when comparing keys.
315 They are now passed through (except when using the C API function
316 ``PyDict_GetItem()``, whose semantics did not change).
317
318- Bug #1456209: In some obscure cases it was possible for a class with a
319 custom ``__eq__()`` method to confuse dict internals when class instances
320 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
321 No, you don't have any code that did this ;-)

324-----------------
325
Trent Mick960a3f82006-06-28 20:30:41 +0000326- Bug #1295808: expat symbols should be namespaced in pyexpat
327
328- Patch #1462338: Upgrade pyexpat to expat 2.0.0
329
Brett Cannon6ee7d012006-06-08 16:23:04 +0000330- Change binascii.hexlify to accept a read-only buffer instead of only a char
331 buffer and actually follow its documentation.
332
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000333- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
334
Nick Coghlanc649ec52006-05-29 12:43:05 +0000335- Patch #1478788 (modified version): The functional extension module has
336 been renamed to _functools and a functools Python wrapper module added.
337 This provides a home for additional function related utilities that are
338 not specifically about functional programming. See PEP 309.
339
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000340- Patch #1493701: performance enhancements for struct module.
341
Georg Brandl378d5922006-05-17 14:26:50 +0000342- Patch #1490224: time.altzone is now set correctly on Cygwin.
343
Georg Brandl8d3342b2006-05-16 07:38:27 +0000344- Patch #1435422: zlib's compress and decompress objects now have a
345 copy() method.
346
Andrew MacIntyre92913322006-06-13 15:04:24 +0000347- Patch #1454481: thread stack size is now tunable at runtime for thread
348 enabled builds on Windows and systems with Posix threads support.
349
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000350- On Win32, os.listdir now supports arbitrarily-long Unicode path names
351 (up to the system limit of 32K characters).
352
353- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
354 As a result, these functions now raise WindowsError instead of OSError.
355
Tim Peters7a822da2006-05-25 21:50:17 +0000356- ``time.clock()`` on Win64 should use the high-performance Windows
357 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
358 Windows platforms).
359
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000360- Calling Tk_Init twice is refused if the first call failed as that
361 may deadlock.
362
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000363- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
364 accept it without potentially using an uninitialized pointer.
365
366- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
367 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
368 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000369
Gregory P. Smith372b5832006-06-05 18:48:21 +0000370- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000371 [pybsddb project SF patch number 1466734]
372
Gregory P. Smith372b5832006-06-05 18:48:21 +0000373- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
374 parameter is supplied. [SF pybsddb bug #1477863]
375
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000376- bsddb: the __len__ method of a DB object has been fixed to return correct
377 results. It could previously incorrectly return 0 in some cases.
378 Fixes SF bug 1493322 (pybsddb bug 1184012).
379
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000380- bsddb: the bsddb.dbtables Modify method now raises the proper error and
381 aborts the db transaction safely when a modifier callback fails.
382 Fixes SF python patch/bug #1408584.
383
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000384- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000385 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000386 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
387 database calls that would previously deadlock. [SF python bug #775414]
388
Vinay Sajip28e57612006-07-01 10:45:20 +0000389- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000390
Walter Dörwald4994d952006-06-19 08:07:50 +0000391- Patch #1506645: add Python wrappers for the curses functions
392 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000393

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000397- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
398 functions.
399
Martin v. Löwis3798da02006-06-17 18:44:27 +0000400- Patch #812986: Update turtle output even if not tracing.
401
Vinay Sajip28e57612006-07-01 10:45:20 +0000402- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000403 Tkinter.BaseWidget.
404
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000405- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
406
Martin v. Löwis337487e2006-06-17 09:15:14 +0000407- Patch #763580: Add name and value arguments to Tkinter variable
408 classes.
409
Georg Brandl83cc0d02006-06-14 08:50:03 +0000410- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
411 mime.types file for determining MIME types.
412
Georg Brandl2605ca82006-06-14 06:08:31 +0000413- Bug #1339007: Shelf objects now don't raise an exception in their
414 __del__ method when initialization failed.
415
Martin v. Löwisd8251432006-06-14 05:21:04 +0000416- Patch #1455898: The MBCS codec now supports the incremental mode for
417 double-byte encodings.
418
Tim Peters43898b42006-06-14 04:09:25 +0000419- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
420 guarantee that adjacent triples in the return list always describe
421 non-adjacent blocks. Previously, a pair of matching blocks could end
422 up being described by multiple adjacent triples that formed a partition
423 of the matching pair.
424
Greg Ward0e0c9f42006-06-11 16:24:11 +0000425- Bug #1498146: fix optparse to handle Unicode strings in option help,
426 description, and epilog.
427
Greg Wardd1c797e2006-06-11 14:42:41 +0000428- Bug #1366250: minor optparse documentation error.
429
Greg Ward7f547402006-06-11 00:40:49 +0000430- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
431 clarify docs.
432
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000433- The wsgiref package has been added to the standard library.
434
Nick Coghlan676725d2006-06-08 13:54:49 +0000435- The functions update_wrapper() and wraps() have been added to the functools
436 module. These make it easier to copy relevant metadata from the original
437 function when writing wrapper functions.
438
Tim Petersd6a9eef2006-06-05 01:48:21 +0000439- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
440 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000441
Martin v. Löwis3f767792006-06-04 19:36:28 +0000442- Patch #1359618: Speed up charmap encoder by using a trie structure
443 for lookup.
444
Tim Petersd609b1a2006-06-02 23:22:51 +0000445- The functions in the ``pprint`` module now sort dictionaries by key
446 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
447 if and only if its display required more than one line, although that
448 wasn't documented. The new behavior increases predictability; e.g.,
449 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
450
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000451- Patch #1497027: try HTTP digest auth before basic auth in urllib2
452 (thanks for J. J. Lee).
453
Georg Brandl2b330372006-05-28 20:23:12 +0000454- Patch #1496206: improve urllib2 handling of passwords with respect to
455 default HTTP and HTTPS ports.
456
George Yoshidaf3c65de2006-05-28 16:39:09 +0000457- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
458
Bob Ippolito7298f272006-05-23 18:43:47 +0000459- Patch #1281707: speed up gzip.readline.
460
Georg Brandlb89316f2006-05-17 15:51:16 +0000461- Patch #1180296: Two new functions were added to the locale module:
462 format_string() to get the effect of "format % items" but locale-aware,
463 and currency() to format a monetary number with currency sign.
464
Georg Brandle3a25832006-05-17 14:56:04 +0000465- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
466 and several features added, such as speed and geometry control.
467
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000468- Patch #1488881: add support for external file objects in bz2 compressed
469 tarfiles.
470
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000471- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
472 stdout arguments, making it possible to redirect input and output
473 for remote debugging.
474
475- Patch #1484695: Update the tarfile module to version 0.8. This fixes
476 a couple of issues, notably handling of long file names using the
477 GNU LONGNAME extension.
478
479- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
480 new flag when ``name`` is already the name of an option flag.
481
482- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
483 package.
484
485- Patch #1472854: make the rlcompleter.Completer class usable on non-
486 UNIX platforms.
487
488- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
489
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000490- Bug #1472827: correctly escape newlines and tabs in attribute values in

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000521What's New in Python 2.5 alpha 2?
522=================================
523
524*Release date: 27-APR-2006*
525
526Core and builtins
527-----------------
528
Thomas Heller1b046642006-04-18 18:51:06 +0000529- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
530 by converting these apis from macros into exported functions again:
531
532 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
533 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
534 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
535 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
536 PyRun_String Py_CompileString
537
Martin v. Löwis45294a92006-04-18 06:24:08 +0000538- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
539
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000540- All uses of PyStructSequence_InitType have been changed to initialize
541 the type objects only once, even if the interpreter is initialized
542 multiple times.
543
Neal Norwitz61546162006-04-14 05:20:28 +0000544- Bug #1454485, array.array('u') could crash the interpreter. This was
545 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
546 to unicode when it didn't make sense. 'u#' now requires a unicode string.
547
548- Py_UNICODE is unsigned. It was always documented as unsigned, but
549 due to a bug had a signed value in previous versions.
550
Tim Peters3a5e8b12006-04-11 01:44:07 +0000551- Patch #837242: ``id()`` of any Python object always gives a positive
552 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
553 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000554 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000555 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000556
Tim Peters3a5e8b12006-04-11 01:44:07 +0000557 def __hash__(self):
558 return id(self) # WRONG
559
560 because a hash result must be a (short) Python int but it was always
561 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000562 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000563 was always usable as a hash value before this patch. That's no longer
564 necessarily so.
565
566- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000567 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000568 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000569 #1454844)
570
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000571- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
572 involving generators that have paused outside of any ``try`` or ``with``
573 blocks. (In 2.5a1, a paused generator that was part of a reference
574 cycle could not be garbage collected, regardless of whether it was
575 paused in a ``try`` or ``with`` block.)

581 is a macro.
582
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000583- Bug #1467952: os.listdir() now correctly raises an error if readdir()
584 fails with an error condition.
585
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000586- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
587
588- Bug #1117761: bsddb.*open() no longer raises an exception when using
589 the cachesize parameter.
590
591- Bug #1149413: bsddb.*open() no longer raises an exception when using
592 a temporary db (file=None) with the 'n' flag to truncate on open.
593
594- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
595 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000596
Armin Rigoa9017c32006-04-19 11:50:27 +0000597- Patch #1062014: AF_UNIX sockets under Linux have a special
598 abstract namespace that is now fully supported.
599
Anthony Baxter51bcb682006-04-05 14:51:42 +0000600Library
601-------
602
Peter Astrand7d1d4362006-07-14 14:04:45 +0000603- Bug #1223937: subprocess.CalledProcessError reports the exit status
604 of the process using the returncode attribute, instead of
605 abusing errno.
606
Tim Peters711bf302006-04-25 03:31:36 +0000607- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
608 a doctest to be skipped (the code is not run, and the expected output
609 or exception is ignored).
610
Nick Coghlanda2268f2006-04-24 04:37:15 +0000611- Fixed contextlib.nested to cope with exceptions being raised and
612 caught inside exit handlers.
613
Greg Wardab05edc2006-04-23 03:47:58 +0000614- Updated optparse module to Optik 1.5.1 (allow numeric constants in
615 hex, octal, or binary; add ``append_const`` action; keep going if
616 gettext cannot be imported; added ``OptionParser.destroy()`` method;
617 added ``epilog`` for better help generation).
618
Tim Peters21fbd572006-04-21 21:18:10 +0000619- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
620 called from a thread spawned as a side effect of importing a module.
621
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000622- The pydoc module now supports documenting packages contained in
623 .zip or .egg files.
624
625- The pkgutil module now has several new utility functions, such
626 as ``walk_packages()`` to support working with packages that are either
627 in the filesystem or zip files.
628
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000629- The mailbox module can now modify and delete messages from
630 mailboxes, in addition to simply reading them. Thanks to Gregory
631 K. Johnson for writing the code, and to the 2005 Google Summer of

659
Anthony Baxter51bcb682006-04-05 14:51:42 +0000660Build
661-----
662
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000663- The Makefile now has a reindent target, which runs reindent.py on
664 the library.
665
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000666- Patch #1470875: Building Python with MS Free Compiler
667
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000668- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000669
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000670- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
671 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000672 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000673 CXX from --with-cxx-main, see description in README.
674
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000675- Patch #1429775: Link extension modules with the shared libpython.
676
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000677- Fixed a libffi build problem on MIPS systems.
678
Tim Peters8931ff12006-05-13 23:28:20 +0000679- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
680 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
681 and "%zu" for unsigned integers of type ``size_t``.
682
Anthony Baxter51bcb682006-04-05 14:51:42 +0000683Tests
684-----
685
Nick Coghlanda2268f2006-04-24 04:37:15 +0000686- test_contextlib now checks contextlib.nested can cope with exceptions
687 being raised and caught inside exit handlers.
688
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000689- test_cmd_line now checks operation of the -m and -c command switches
690
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000691- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
692 it separately and by hand. It also wasn't cleaning up its changes to
693 the current Decimal context.
694
Thomas Woutersabd08882006-04-26 15:53:30 +0000695- regrtest.py now has a -M option to run tests that test the new limits of
696 containers, on 64-bit architectures. Running these tests is only sensible
697 on 64-bit machines with more than two gigabytes of memory. The argument
698 passed is the maximum amount of memory for the tests to use.

707-------------
708
Tim Petersb06d28c2006-05-12 01:57:59 +0000709- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
710
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000711- PEP 343: Added Context Types section to the library reference
712 and attempted to bring other PEP 343 related documentation into
713 line with the implementation and/or python-dev discussions.
714
Tim Peters8dc73d22006-04-24 02:03:16 +0000715- Bug #1337990: clarified that ``doctest`` does not support examples
716 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000719What's New in Python 2.5 alpha 1?
720=================================
721
Anthony Baxterebed3f62006-04-03 15:03:44 +0000722*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000723
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000724Core and builtins
725-----------------
726
Nick Coghlan43832302006-04-23 17:04:07 +0000727- PEP 338: -m command line switch now delegates to runpy.run_module
728 allowing it to support modules in packages and zipfiles
729
Martin v. Löwisc661b882006-04-20 04:54:23 +0000730- On Windows, .DLL is not an accepted file name extension for
731 extension modules anymore; extensions are only found if they
732 end in .PYD.
733
Martin v. Löwisea62d252006-04-03 10:56:49 +0000734- Bug #1421664: sys.stderr.encoding is now set to the same value as
735 sys.stdout.encoding.
736
Neal Norwitz92e212f2006-04-03 04:48:37 +0000737- __import__ accepts keyword arguments.
738
Georg Brandlccadf842006-03-31 18:54:53 +0000739- Patch #1460496: round() now accepts keyword arguments.
740
Anthony Baxter262c00a2006-03-30 10:53:17 +0000741- Fixed bug #1459029 - unicode reprs were double-escaped.
742
Hye-Shik Changd478f342006-03-23 12:32:36 +0000743- Patch #1396919: The system scope threads are reenabled on FreeBSD
744 5.4 and later versions.
745
Neal Norwitze98ccf62006-03-23 05:39:47 +0000746- Bug #1115379: Compiling a Unicode string with an encoding declaration
747 now gives a SyntaxError.
748
Georg Brandlabd1ff82006-03-18 07:59:59 +0000749- Previously, Python code had no easy way to access the contents of a
750 cell object. Now, a ``cell_contents`` attribute has been added
751 (closes patch #1170323).
752
Tim Peterscf79aac2006-03-16 01:14:46 +0000753- Patch #1123430: Python's small-object allocator now returns an arena to
754 the system ``free()`` when all memory within an arena becomes unused
755 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
756 freed. Some applications will see a drop in virtual memory size now,
757 especially long-running applications that, from time to time, temporarily
758 use a large number of small objects. Note that when Python returns an
759 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000760 platform C library will in turn return that memory to the operating system.
761 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000762 appears to be effective at least on Microsoft C and gcc-based systems.
763 Thanks to Evan Jones for hard work and patience.
764
Georg Brandl533ff6f2006-03-08 18:09:27 +0000765- Patch #1434038: property() now uses the getter's docstring if there is
766 no "doc" argument given. This makes it possible to legitimately use
767 property() as a decorator to produce a read-only property.
768
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000769- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
770 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
771 of requiring an int or long in slicing and a few other contexts, enabling
772 other objects (e.g. Numeric Python's integers) to be used as slice indices.
773
Neal Norwitz995acdf2006-03-07 05:01:00 +0000774- Fixed various bugs reported by Coverity's Prevent tool.
775
Brett Cannonbf364092006-03-01 04:25:17 +0000776- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
777 new exception base class, BaseException, which has a new message attribute.
778 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
779 Raising a string exception now raises a DeprecationWarning.
780
Thomas Woutersfb609f42006-02-28 16:37:25 +0000781- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
782 explicitly relative, using 'from .module import name' to mean 'from the same
783 package as this module is in. Imports without dots still default to the
784 old relative-then-absolute, unless 'from __future__ import
785 absolute_import' is used.
786
Brett Cannona7446e32006-02-27 23:39:10 +0000787- Properly check if 'warnings' raises an exception (usually when a filter set
788 to "error" is triggered) when raising a warning for raising string
789 exceptions.
790
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000791- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000792 The name was removed from Include/code.h.
793
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000794- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000795
Guido van Rossum1968ad32006-02-25 22:38:04 +0000796- Patch 1433928:
797 - The copy module now "copies" function objects (as atomic objects).
798 - dict.__getitem__ now looks for a __missing__ hook before raising
799 KeyError.
800
Tim Peters84ef21c2006-02-28 20:39:06 +0000801- PEP 343: with statement implemented. Needs ``from __future__ import
802 with_statement``. Use of 'with' as a variable will generate a warning.
803 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000804 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000805 The following objects have __context__ methods:
806 - The built-in file type.
807 - The thread.LockType type.
808 - The following types defined by the threading module:
809 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
810 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000811
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000812- Fix the encodings package codec search function to only search
813 inside its own package. Fixes problem reported in patch #1433198.
814
815 Note: Codec packages should implement and register their own
816 codec search function. PEP 100 has the details.
817
Tim Peters9ea89d22006-06-04 03:26:02 +0000818- PEP 353: Using ``Py_ssize_t`` as the index type.
819
820- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
821 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
822 now allow Python to make use of memory blocks exceeding 2**32 bytes for
823 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
824 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000825
Neal Norwitzfc76d632006-01-10 06:03:13 +0000826- Patch #1400181, fix unicode string formatting to not use the locale.
827 This is how string objects work. u'%f' could use , instead of .
828 for the decimal point. Now both strings and unicode always use periods.
829
Neal Norwitz671b9e32006-01-09 07:07:12 +0000830- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
831 configure would break checking curses.h.
832
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000833- Bug #959576: The pwd module is now builtin. This allows Python to be
834 built on UNIX platforms without $HOME set.
835
Neal Norwitzc10978f2005-12-19 06:07:16 +0000836- Bug #1072182, fix some potential problems if characters are signed.
837
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000838- Bug #889500, fix line number on SyntaxWarning for global declarations.
839
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000840- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
841
Neal Norwitze7214a12005-12-18 05:03:17 +0000842- Support for converting hex strings to floats no longer works.
843 This was not portable. float('0x3') now raises a ValueError.
844
Barry Warsaw2a38a862005-12-18 01:27:35 +0000845- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000846 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000847 is now displayed in interactive prompt banner.
848
Georg Brandlfa166682005-12-17 21:45:17 +0000849- Implementation of PEP 341 - Unification of try/except and try/finally.
850 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000851 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000852
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000853- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
854 now encodes backslash correctly.
855
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000856- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
857
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000858- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000859 and long longs.
860
Neal Norwitz67715f02005-11-09 06:59:35 +0000861- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000862 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000863 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000864
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000865- Replaced most Unicode charmap codecs with new ones using the
866 new Unicode translate string feature in the builtin charmap
867 codec; the codecs were created from the mapping tables available
868 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
869 encodings now include a mapping for the Apple logo)
870
Tim Peterse3547fd2005-12-16 23:13:57 +0000871- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000872
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000873- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000874
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000875- A new AST parser implementation was completed. The abstract
876 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000877 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000878
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000879- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000880 The following code now raises a SyntaxError: foo(a = i for i in range(10))
881
Neal Norwitz708e51a2005-10-03 04:48:15 +0000882- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
883
Neal Norwitz11bd1192005-10-03 00:54:56 +0000884- SF Bug #887946: fix segfault when redirecting stdin from a directory.
885 Provide a warning when a directory is passed on the command line.
886
Neal Norwitz40d37812005-10-02 01:48:49 +0000887- Fix segfault with invalid coding.
888
889- SF bug #772896: unknown encoding results in MemoryError.
890
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000891- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000892 supported a __len__() method which evaluated to False when the iterator
893 was empty.
894
Guido van Rossum630db602005-09-20 18:49:54 +0000895- On 64-bit platforms, when __len__() returns a value that cannot be
896 represented as a C int, raise OverflowError.
897
Skip Montanarof8948ca2005-09-19 03:54:46 +0000898- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000899 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000900
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000901- SF bug #893549: parsing keyword arguments was broken with a few format
902 codes.
903
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000904- Changes donated by Elemental Security to make it work on AIX 5.3
905 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
906 bug #105470: test_pwd fails on 64bit system (Opteron).
907
Guido van Rossum539c6622005-09-14 17:49:54 +0000908- Changes donated by Elemental Security to make it work on HP-UX 11 on
909 Itanium2 with HP's 64-bit compiler (SF patch #1225212).

Georg Brandl4550b8d2005-08-26 06:43:52 +0000911- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000912 (fixes bug #1119418).
913
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000914- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
915
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000916- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
917 exceptions that cause a function to exit.
918
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000919- The implementation of set() and frozenset() was revised to use its
920 own internal data structure. Memory consumption is reduced by 1/3
921 and there are modest speed-ups as well. The API is unchanged.
922
Tim Petersde7990b2005-07-17 23:45:23 +0000923- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
924
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000925- SF bug #1229429: PyObject_CallMethod failed to decrement some
926 reference counts in some error exit cases.
927
Tim Petersecc6e6a2005-07-10 22:30:55 +0000928- SF bug #1185883: Python's small-object memory allocator took over
929 a block managed by the platform C library whenever a realloc specified
930 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000931 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000932 portable way to copy data from the C-managed block into Python's
933 small-object space without risking a memory fault. Python's small-object
934 realloc now leaves such blocks under the control of the platform C
935 realloc.
936
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000937- SF bug #1232517: An overflow error was not detected properly when
938 attempting to convert a large float to an int in os.utime().
939
Raymond Hettinger3296e692005-06-29 23:29:56 +0000940- SF bug #1224347: hex longs now print with lowercase letters just
941 like their int counterparts.
942
Michael W. Hudson188d4362005-06-20 16:52:57 +0000943- SF bug #1163563: the original fix for bug #1010677 ("thread Module
944 Breaks PyGILState_Ensure()") broke badly in the case of multiple
945 interpreter states; back out that fix and do a better job (see
946 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
947 for a longer write-up of the problem).
948
Michael W. Hudsondf888462005-06-03 14:41:55 +0000949- SF patch #1180995: marshal now uses a binary format by default when
950 serializing floats.
951
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000952- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
953 the routines that promise to produce IEEE 754 binary representations
954 of floats now simply copy bytes around.
955
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000956- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
957 278.
958
Brett Cannonc3647ac2005-04-26 03:45:26 +0000959- patch #1109424: int, long, float, complex, and unicode now check for the
960 proper magic slot for type conversions when subclassed. Previously the
961 magic slot was ignored during conversion. Semantics now match the way
962 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000963 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000964 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000965 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000966
Barry Warsawc8d907c2005-04-19 23:43:40 +0000967- Descriptors defined in C with a PyGetSetDef structure, where the setter is
968 NULL, now raise an AttributeError when attempting to set or delete the
969 attribute. Previously a TypeError was raised, but this was inconsistent
970 with the equivalent pure-Python implementation.
971
Michael W. Hudson774479c2005-04-18 08:46:17 +0000972- It is now safe to call PyGILState_Release() before
973 PyEval_InitThreads() (note that if there is reason to believe there
974 are multiple threads around you still must call PyEval_InitThreads()
975 before using the Python API; this fix is for extension modules that
976 have no way of knowing if Python is multi-threaded yet).
977
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000978- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
979 disabled caused a crash.
980
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000981- Bug #1165306: instancemethod_new allowed the creation of a method
982 with im_class == im_self == NULL, which caused a crash when called.
983
Tim Petersecc6e6a2005-07-10 22:30:55 +0000984- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000985 fixes the crash seen in bug #1165761
986
Raymond Hettinger96229b12005-03-11 06:49:40 +0000987- Added two new builtins, any() and all().
988
Brett Cannon409d8f22005-03-05 06:47:57 +0000989- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000990 (e.g., ``class C(): pass`` is no longer a syntax error).
991 Patch #1176012 added support to the 'parser' module and 'compiler' package
992 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000993
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000994- Patch #1115086: Support PY_LONGLONG in structmember.
995
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000996- Bug #1155938: new style classes did not check that __init__() was
997 returning None.
998
Tim Petersecc6e6a2005-07-10 22:30:55 +0000999- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001000 ('\') with a specific error message.
1001
Martin v. Löwisff232d72005-03-03 09:24:38 +00001002- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1003
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001004- Bug #1124295: the __name__ attribute of file objects was
1005 inadvertently made inaccessible in restricted mode.
1006
Tim Petersecc6e6a2005-07-10 22:30:55 +00001007- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001008 an ferror() call.
1009
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001010- min() and max() now support key= arguments with the same meaning as in
1011 list.sort().
1012
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001013- The peephole optimizer now performs simple constant folding in expressions:
1014 (2+3) --> (5).
1015
Raymond Hettingera422c342005-01-11 03:03:27 +00001016- set and frozenset objects can now be marshalled. SF #1098985.
1017
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001018- Bug #1077106: Poor argument checking could cause memory corruption
1019 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001020
Jeremy Hyltonab630502005-02-04 18:44:06 +00001021- The parser did not complain about future statements in illegal
1022 positions. It once again reports a syntax error if a future
1023 statement occurs after anything other than a doc string.
1024
Neil Schemenauercf52c072005-08-12 17:34:58 +00001025- Change the %s format specifier for str objects so that it returns a
1026 unicode instance if the argument is not an instance of basestring and
1027 calling __str__ on the argument returns a unicode instance.
1028
Tim Petersf4e69282006-02-27 17:15:31 +00001029- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1030 current thread state when the auto-GIL-state machinery knows about
1031 it (since the thread state is being deleted, continuing to remember it
1032 can't help, but can hurt if another thread happens to get created with
1033 the same thread id).
1034
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001035Extension Modules
1036-----------------
1037

Tim Petersc9d78aa2006-03-26 23:27:58 +00001050 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001051 util, whatsound, whrandom, zmod
1052
1053- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1054
1055- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001056 is deprecated. The undocumented re.engine variable no longer exists.
1057
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001058- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1059 SS2 (single-shift 2) escape sequences correctly.
1060
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001061- The unicodedata module was updated to the 4.1 version of the Unicode
1062 database. The 3.2 version is still available as unicodedata.db_3_2_0
1063 for applications that require this specific version (such as IDNA).
1064
Neal Norwitzb62c4332006-03-04 18:35:47 +00001065- The timing module is no longer built by default. It was deprecated
1066 in PEP 4 in Python 2.0 or earlier.
1067
Guido van Rossum1968ad32006-02-25 22:38:04 +00001068- Patch 1433928: Added a new type, defaultdict, to the collections module.
1069 This uses the new __missing__ hook behavior added to dict (see above).
1070
Georg Brandldbd83392006-02-20 09:42:33 +00001071- Bug #854823: socketmodule now builds on Sun platforms even when
1072 INET_ADDRSTRLEN is not defined.
1073
Georg Brandlf4f44152006-02-18 22:29:33 +00001074- Patch #1393157: os.startfile() now has an optional argument to specify
1075 a "command verb" to invoke on the file.
1076

Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001080- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1081 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1082 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1083
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001084- Patch #1422385: The nis module now supports access to domains other
1085 than the system default domain.
1086
Martin v. Löwis14694662006-02-03 12:54:16 +00001087- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1088 are reported, the limit on path name lengths is removed, and stat reports
1089 WindowsError now (instead of OSError).
1090
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001091- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

Michael W. Hudson8137bea2005-07-27 20:24:40 +00001165- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
1166 the request code argument, which results in more C-like behaviour
1167 for large or negative values.
1168
Tim Petersecc6e6a2005-07-10 22:30:55 +00001169- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

1184
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00001185- operator.itemgetter() and operator.attrgetter() now support retrieving

1208
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001209- the cPickle module no longer accepts the deprecated None option in the
1210 args tuple returned by __reduce__().
1211
Raymond Hettingerb2594052004-12-05 09:25:51 +00001212- itertools.islice() now accepts None for the start and step arguments.
1213 This allows islice() to work more readily with slices:
1214 islice(s.start, s.stop, s.step)
1215
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001216- datetime.datetime() now has a strptime class method which can be used to

Tim Peters112aad32006-07-19 00:03:19 +00001224
Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001225- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1226 been renamed to have only a single underscore prefix. This was done to
1227 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001228
Nick Coghlan43832302006-04-23 17:04:07 +00001229- PEP 338: new module runpy defines a run_module function to support
1230 executing modules which provide access to source code or a code object
1231 via the PEP 302 import mechanisms.
1232
Anthony Baxter93f5b932006-04-03 08:05:07 +00001233- The email module's parsedate_tz function now sets the daylight savings
1234 flag to -1 (unknown) since it can't tell from the date whether it should

1241 in attribute values.
1242
Anthony Baxterc51ee692006-04-01 00:57:31 +00001243- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001244 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001245 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001246 module will not be built.
1247
Tim Petersc17976e2006-04-01 00:26:53 +00001248- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1249 aren't officially supported here, and trying to use them will probably
1250 raise an exception some day. But dicts have been allowed, and "mostly
1251 worked", so support for them won't go away without warning.
1252
Georg Brandl338ef7d2006-03-31 18:42:16 +00001253- Bug #1445068: getpass.getpass() can now be given an explicit stream
1254 argument to specify where to write the prompt.
1255
Georg Brandl22ec80b2006-03-31 18:25:44 +00001256- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1263
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001264- Queue.Queue objects now support .task_done() and .join() methods
1265 to make it easier to monitor when daemon threads have completed
1266 processing all enqueued tasks. Patch #1455676.
1267
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001268- popen2.Popen objects now preserve the command in a .cmd attribute.

1271
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001272- email 4.0 package now integrated. This is largely the same as the email 3.0
1273 package that was included in Python 2.3, except that PEP 8 module names are
1274 now used (e.g. mail.message instead of email.Message). The MIME classes
1275 have been moved to a subpackage (e.g. email.mime.text instead of
1276 email.MIMEText). The old names are still supported for now. Several
1277 deprecated Message methods have been removed and lots of bugs have been
1278 fixed. More details can be found in the email package documentation.
1279
Walter Dörwald40108c92006-03-27 08:15:44 +00001280- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1281 (a subclass of tuple) that provides incremental decoders and encoders
1282 (a way to use stateful codecs without the stream API). Python functions
1283 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1284 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1285 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001286
Walter Dörwald067db482006-03-15 22:17:27 +00001287- Patch #1359365: Calling next() on a closed StringIO.String object raises
1288 a ValueError instead of a StopIteration now (like file and cString.String do).
1289 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1290 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001291
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001292- A regrtest option -w was added to re-run failed tests in verbose mode.

Tim Peterse3547fd2005-12-16 23:13:57 +00001364 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1365 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1366 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1367 Ronald L. Rivest offered this advice for Python:
1368
1369 "The consensus of researchers in this area (at least as
1370 expressed at the NIST Hash Function Workshop 10/31/05),
1371 is that SHA-256 is a good choice for the time being, but
1372 that research should continue, and other alternatives may
1373 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001374
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001375- Added a subset of Fredrik Lundh's ElementTree package. Available

Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001448- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00001449 Patch #1209527 (Contributed by Connelly).
1450
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00001451- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
1452 to W3C name (404 -> 'Not Found'). RFE #1216944.
1453
Georg Brandl9e43acf2005-07-04 17:16:07 +00001454- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1455 as this can cause problems with apps closing all file descriptors.
1456
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001457- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001458 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00001459
Georg Brandl2f210b62005-06-26 22:09:06 +00001460- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
1461
Georg Brandlfbff1bc2005-06-26 21:36:25 +00001462- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
1463 error messages.
1464
Georg Brandl379f99d2005-06-26 21:09:38 +00001465- Bug #1108948: Cookie.py produced invalid JavaScript code.
1466
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001467- The tokenize module now detects and reports indentation errors.
1468 Bug #1224621.
1469
Raymond Hettinger68c04532005-06-10 11:05:19 +00001470- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001471 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001472 the generate_tokens() function now accepts a callable argument that
1473 terminates by raising StopIteration.
1474
Georg Brandl9166e1a2005-06-04 09:20:03 +00001475- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1476
Georg Brandl268e61c2005-06-03 14:28:50 +00001477- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1478 component of the path.
1479
Skip Montanaro174dd222005-05-14 20:54:16 +00001480- Patch #1120353: The xmlrpclib module provides better, more transparent,
1481 support for datetime.{datetime,date,time} objects. With use_datetime set
1482 to True, applications shouldn't have to fiddle with the DateTime wrapper
1483 class at all.
1484
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001485- distutils.commands.upload was added to support uploading distribution
1486 files to PyPI.
1487
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001488- distutils.commands.register now encodes the data as UTF-8 before posting
1489 them to PyPI.
1490
Raymond Hettinger267b8682005-03-27 10:47:39 +00001491- decimal operator and comparison methods now return NotImplemented
1492 instead of raising a TypeError when interacting with other types. This
1493 allows other classes to implement __radd__ style methods and have them
1494 work as expected.
1495
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001496- Bug #1163325: Decimal infinities failed to hash. Attempting to
1497 hash a NaN raised an InvalidOperation instead of a TypeError.
1498
Tim Petersecc6e6a2005-07-10 22:30:55 +00001499- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001500 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1501

Raymond Hettingerbab41432005-02-05 01:31:19 +00001532- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1533
Guido van Rossumd0641422005-02-03 15:01:24 +00001534- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1535 disables recursive traversal through instance attributes, which can
1536 be exploited in various ways.
1537
Tim Peterse3547fd2005-12-16 23:13:57 +00001538- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001539 flags on the HTTP listening socket.
1540
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001541- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1542 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1543
Tim Peterse3547fd2005-12-16 23:13:57 +00001544- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001545 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1546
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001547- Bug #1110478: Revert os.environ.update to do putenv again.
1548
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001549- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1550
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001551- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1552
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001553- Enhancements to the csv module:
1554
1555 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001556 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001557 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001558 + Dialect parameter parsing has been re-implemented to improve error
1559 reporting.
1560 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1561 dictates.
1562 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001563 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001564 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001565 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1566 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001567 + reader now allows \r characters to be quoted (previously it only allowed
1568 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001569 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001570 + Dialect classes passed to the module are no longer instantiated by
1571 the module before being parsed (the former validation scheme required
1572 this, but the mechanism was unreliable).
1573 + The dialect registry now contains instances of the internal
1574 C-coded dialect type, rather than references to python objects.
1575 + the internal c-coded dialect type is now immutable.
1576 + register_dialect now accepts the same keyword dialect specifications
1577 as the reader and writer, allowing the user to register dialects
1578 without first creating a dialect class.
1579 + a configurable limit to the size of parsed fields has been added -
1580 previously, an unmatched quote character could result in the entire
1581 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001582 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001583 the parser field size limit (returning the former limit). The initial
1584 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001585 + A line_num attribute has been added to the reader object, which tracks
1586 the number of lines read from the source iterator. This is not
1587 the same as the number of records returned, as records can span
1588 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001589 + reader and writer objects were not being registered with the cyclic-GC.
1590 This has been fixed.
1591
Brett Cannone6539c42005-01-08 02:43:53 +00001592- _DummyThread objects in the threading module now delete self.__block that is
1593 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1594 lock primitives tend to be limited in number and thus should not be wasted on
1595 a _DummyThread object. Fixes bug #1089632.
1596
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001597- The imghdr module now detects Exif files.
1598
Raymond Hettinger6065d322004-12-20 23:51:53 +00001599- StringIO.truncate() now correctly adjusts the size attribute.
1600 (Bug #951915).
1601
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001602- locale.py now uses an updated locale alias table (built using
1603 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1604 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001605 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001606
Raymond Hettinger3557f422004-12-07 12:02:02 +00001607- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1608
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001609- the pickle module no longer accepts the deprecated None option in the
1610 args tuple returned by __reduce__().
1611
Brett Cannon84667c02004-12-07 03:25:18 +00001612- optparse now optionally imports gettext. This allows its use in setup.py.
1613
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001614- the pickle module no longer uses the deprecated bin parameter.
1615
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001616- the shelve module no longer uses the deprecated binary parameter.
1617
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001618- the pstats module no longer uses the deprecated ignore() method.
1619
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001620- the filecmp module no longer uses the deprecated use_statcache argument.
1621
Raymond Hettinger664347b2004-12-04 21:21:53 +00001622- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1623 extended or overridden by subclasses. Formerly, the subclassed method would
1624 be ignored by the rest of the module. (Bug #1078905).
1625
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001626- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001627 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001628
Walter Dörwald36733692004-12-22 12:50:50 +00001629- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1630 once when a size argument is given. This prevents a buffer overflow in the
1631 tokenizer with very long source lines.
1632
Barry Warsaw538561e2006-01-01 21:48:54 +00001633- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1634 immediately after creating the object, without any intervening
1635 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001636
Skip Montanaro05885812005-01-16 20:48:27 +00001637- The reconvert.quote function can now emit triple-quoted strings. The
1638 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001639
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001640- ``UserString.MutableString`` now supports negative indices in
1641 ``__setitem__`` and ``__delitem__``
1642
Greg Ward40407942005-03-05 02:53:17 +00001643- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1644 correctly.
1645
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001646- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1647 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1648 character even if the user has passed a size parameter to get a proper
1649 line ending. Remove the special handling of a "\r\n" that has been split
1650 between two lines.
1651
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001652- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1653 about illegal code points. The codec now supports PEP 293 style error
1654 handlers.
1655
Walter Dörwald78a78b02005-09-01 12:04:29 +00001656- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001657 from the input stream, so that the output is a byte string in the correct
1658 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001659
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001660- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1661 considering it exactly like a '*'.
1662
Walter Dörwald007f8df2005-10-09 19:42:27 +00001663- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1664 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001665
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001666- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1667
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001668- Patch #1413711: Certain patterns of differences were making difflib
1669 touch the recursion limit.
1670
Walter Dörwald58917a62006-03-31 15:26:22 +00001671- Bug #947906: An object oriented interface has been added to the calendar
1672 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001673 called as a script (e.g. via ``python -mcalendar``). Localized month and
1674 weekday names can be ouput (even if an exotic encoding is used) using
1675 special classes that use unicode.

Brett Cannon08cd5982005-04-24 22:26:38 +00001702- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1703 flags that change binary compatibility. Changes were also made to
1704 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001705 compilation of the interpreter and of C extensions through distutils.

Bob Ippolitoed233462005-03-29 13:47:59 +00001707- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1708 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1709 no longer exists). This configure patch makes things right.
1710
Martin v. Löwise2713be2005-03-08 15:03:08 +00001711- Bug #1158607: Build with --disable-unicode again.
1712
Brett Cannon46d96232005-02-16 00:07:19 +00001713- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1714 defined. Discovered as a result of not being able to build on OS X.
1715
Brett Cannon516592f2004-12-07 00:42:59 +00001716- setup.py now uses the directories specified in LDFLAGS using the -L option
1717 and in CPPFLAGS using the -I option for adding library and include
1718 directories, respectively, for compiling extension modules against. This has
1719 led to the core being compiled using the values in CPPFLAGS. It also removes
1720 the need for the special-casing of both DarwinPorts and Fink for darwin since
1721 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1722 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1723 Fink, ``-I/opt/local/include`` for DarwinPorts).
1724
Brett Cannon43802422005-02-10 20:48:03 +00001725- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1726 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1727 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1728 Closes bug #1096244. Thanks Gregory Bond.

1731-----
1732
Tim Petersc9d78aa2006-03-26 23:27:58 +00001733- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1734 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1735 is obtained via the ``PyObject_`` family, it must be released via the
1736 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1737 always been officially true, but when Python's small-object allocator was
1738 introduced, an attempt was made to cater to a few extension modules
1739 discovered at the time that obtained memory via ``PyObject_New`` but
1740 released it via ``PyMem_DEL``. It's years later, and if such code still
1741 exists it will fail now (probably with segfaults, but calling wrong
1742 low-level memory management functions can yield many symptoms).
1743
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001744- Added a C API for set and frozenset objects.
1745
Raymond Hettinger66517482004-12-03 11:45:13 +00001746- Removed PyRange_New().
1747
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001748- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1749 mapping argument now. This string is used as a mapping table. Byte values
1750 greater than the length of the string and 0xFFFE are treated as undefined
1751 mappings.

Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001759- Patch #1276356: New resource "urlfetch" is implemented. This enables
1760 even impatient people to run tests that require remote files.
