Neal Norwitza1f10902006-07-12 07:28:29 +00007What's New in Python 2.5 release candidate 1?
8=============================================
9
10*Release date: XX-AUG-2006*
11
12Core and builtins
13-----------------
14
Martin v. Löwis982e9fe2006-07-24 12:54:17 +000015- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
16
Martin v. Löwisd22968a2006-07-24 11:54:53 +000017- Patch #1232023: Stop including current directory in search
18 path on Windows.
19
Neal Norwitze1fdb322006-07-21 05:32:28 +000020- Fix some potential crashes found with failmalloc.
21
Neal Norwitze7563102006-07-17 01:00:16 +000022- Fix warnings reported by Klocwork's static analysis tool.
23
Neal Norwitz84be93b2006-07-16 01:50:38 +000024- Bug #1512814, Fix incorrect lineno's when code within a function
25 had more than 255 blank lines.
26
Georg Brandl9dceedb2006-07-12 15:31:17 +000027- Patch #1521179: Python now accepts the standard options ``--help`` and
28 ``--version`` as well as ``/?`` on Windows.
29
Neal Norwitza1f10902006-07-12 07:28:29 +000030- Bug #1520864: unpacking singleton tuples in for loop (for x, in) work
31 again. Fixing this problem required changing the .pyc magic number.
32 This means that .pyc files generated before 2.5c1 will be regenerated.
33
Tim Peters112aad32006-07-19 00:03:19 +000034- Bug #1524317: Compiling Python ``--without-threads`` failed.
35 The Python core compiles again then, and, in a build without threads, the
36 new ``sys._current_frames()`` returns a dictionary with one entry,
37 mapping the faux "thread id" 0 to the current frame.
38
Neal Norwitza1f10902006-07-12 07:28:29 +000039Library
40-------
41
Greg Ward48fae7a2006-07-23 16:05:51 +000042- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
43
Martin v. Löwis426f4a12006-07-18 17:46:31 +000044- Patch #1524429: Use repr() instead of backticks in Tkinter again.
45
Brett Cannoncaebe222006-07-18 04:41:36 +000046- Bug #1520914: Change time.strftime() to accept a zero for any position in its
47 argument tuple. For arguments where zero is illegal, the value is forced to
48 the minimum value that is correct. This is to support an undocumented but
49 common way people used to fill in inconsequential information in the time
50 tuple pre-2.4.
51
Bob Ippolito5ea4bf12006-07-15 16:53:15 +000052- Patch #1220874: Update the binhex module for Mach-O.
53
Barry Warsawb110bad2006-07-21 14:51:07 +000054- The email package has improved RFC 2231 support, specifically for
55 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
56 (name*0=<blah>) parameter continuations. This may change the types of
57 values returned from email.message.Message.get_param() and friends.
58 Specifically in some cases where non-encoded continuations were used,
59 get_param() used to return a 3-tuple of (None, None, string) whereas now it
60 will just return the string (since non-encoded continuations don't have
61 charset and language parts).
62
63 Also, whereas % values were decoded in all parameter continuations, they are
64 now only decoded in encoded parameter parts.

67-----------------
68
Martin v. Löwisbda0dde2006-07-24 10:26:33 +000069- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
70
Thomas Hellerce049a02006-07-14 17:51:14 +000071- Patch #1521817: Index range checking on ctypes arrays containing
72 exactly one element enabled again. This allows iterating over these
73 arrays, without the need to check the array size before.
74
Thomas Heller6e1ad2e2006-07-13 17:05:13 +000075- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +000076 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +000077 /dev/null in certain cases; this is now fixed.
78
Thomas Heller47d7a062006-07-12 08:43:47 +000079- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
80 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +000081
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +000082- Because of a misspelled preprocessor symbol, ctypes was always
83 compiled without thread support; this is now fixed.

90Core and builtins
91-----------------
92
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +000093- Bug #1441486: The literal representation of -(sys.maxint - 1)
94 again evaluates to a int object, not a long.
95
Neil Schemenauer0e07b602006-07-09 16:16:34 +000096- Bug #1501934: The scope of global variables that are locally assigned
97 using augmented assignment is now correctly determined.
98
Martin v. Löwisd5cfa542006-07-03 13:47:40 +000099- Bug #927248: Recursive method-wrapper objects can now safely
100 be released.
101
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000102- Bug #1417699: Reject locale-specific decimal point in float()
103 and atof().
104
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000105- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
106 omit a default "error" argument for NULL pointer. This allows
107 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000108
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000109- Bug #1519018: 'as' is now validated properly in import statements.
110
Neal Norwitz28746ab2006-07-09 22:14:42 +0000111- On 64 bit systems, int literals that use less than 64 bits are
112 now ints rather than longs.
113
Neal Norwitzed657552006-07-10 00:04:44 +0000114- Bug #1512814, Fix incorrect lineno's when code at module scope
115 started after line 256.
116
Tim Peters32a83612006-07-10 21:08:24 +0000117- New function ``sys._current_frames()`` returns a dict mapping thread
118 id to topmost thread stack frame. This is for expert use, and is
119 especially useful for debugging application deadlocks. The functionality
120 was previously available in Fazal Majid's ``threadframe`` extension
121 module, but it wasn't possible to do this in a wholly threadsafe way from
122 an extension.
123

128
Tim Peters32a83612006-07-10 21:08:24 +0000129- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000130 environment variable to be set in order to the SDK environment
131 for finding the compiler, include files, etc.
132
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000133- Bug #1515998: Properly generate logical ids for files in bdist_msi.
134
Nick Coghlan2d792252006-07-06 13:47:18 +0000135- warnings.py now ignores ImportWarning by default
136
Thomas Woutersadd19112006-07-05 11:03:49 +0000137- string.Template() now correctly handles tuple-values. Previously,
138 multi-value tuples would raise an exception and single-value tuples would
139 be treated as the value they contain, instead.
140
Martin v. Löwisede77f52006-07-03 13:01:35 +0000141- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
142 even if some data are received.
143
Martin v. Löwis45482392006-07-03 12:28:58 +0000144- Bug #1267547: Put proper recursive setup.py call into the
145 spec file generated by bdist_rpm.
146
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000147- Bug #1514693: Update turtle's heading when switching between
148 degrees and radians.
149
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000150- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000151 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000152
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000153- Bug #1514703: Only setup canvas window in turtle when the canvas
154 is created.
155
Martin v. Löwis7596e832006-07-01 15:33:37 +0000156- Bug #1513223: .close() of a _socketobj now releases the underlying
157 socket again, which then gets closed as it becomes unreferenced.
158
Fred Drake10497c82006-06-29 02:57:48 +0000159- Bug #1504333: Make sgmllib support angle brackets in quoted
160 attribute values.
161
162- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
163 sgmllib ('[' and ']' were not accepted).
164
Georg Brandl1be63af2006-06-28 20:23:25 +0000165- Fix a bug in the turtle module's end_fill function.
166
Brett Cannon53ab5b72006-06-22 16:49:14 +0000167- Bug #1510580: The 'warnings' module improperly required that a Warning
168 category be either a types.ClassType and a subclass of Warning. The proper
169 check is just that it is a subclass with Warning as the documentation states.
170
Georg Brandlad29e632006-06-21 17:45:17 +0000171- The compiler module now correctly compiles the new try-except-finally
172 statement (bug #1509132).
173
Neal Norwitz60373cd2006-06-22 06:30:50 +0000174- The wsgiref package is now installed properly on Unix.
175
Vinay Sajip28e57612006-07-01 10:45:20 +0000176- A bug was fixed in logging.config.fileConfig() which caused a crash on
177 shutdown when fileConfig() was called multiple times.
178
Gerhard Häring762fbd32006-07-02 17:48:30 +0000179- The sqlite3 module did cut off data from the SQLite database at the first
180 null character before sending it to a custom converter. This has been fixed
181 now.
182
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000183Extension Modules
184-----------------
185
Tim Peters112aad32006-07-19 00:03:19 +0000186- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
187 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
188 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000189
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000190- Assigning None to pointer type fields in ctypes structures possible
191 overwrote the wrong fields, this is fixed now.
192
193- Fixed a segfault in _ctypes when ctypes.wintypes were imported
194 on non-Windows platforms.
195
196- Bug #1518190: The ctypes.c_void_p constructor now accepts any
197 integer or long, without range checking.
198
199- Patch #1517790: It is now possible to use custom objects in the ctypes
200 foreign function argtypes sequence as long as they provide a from_param
201 method, no longer is it required that the object is a ctypes type.
202
203- The '_ctypes' extension module now works when Python is configured
204 with the --without-threads option.
205
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000206- Bug #1513646: os.access on Windows now correctly determines write
207 access, again.
208
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000209- Bug #1512695: cPickle.loads could crash if it was interrupted with
210 a KeyboardInterrupt.
211
Neal Norwitza12aa882006-07-06 06:45:08 +0000212- Bug #1296433: parsing XML with a non-default encoding and
213 a CharacterDataHandler could crash the interpreter in pyexpat.
214
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000215- Patch #1516912: improve Modules support for OpenVMS.
216
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000217Build
218-----
219
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000220- Automate Windows build process for the Win64 SSL module.
221
Tim Peters32a83612006-07-10 21:08:24 +0000222- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000223 Previously, the slight difference could cause compilation errors of the
224 'zlib' module on systems with more than one version of zlib.
225
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000226- The MSI compileall step was fixed to also support a TARGETDIR
227 with spaces in it.
228
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000229- Bug #1517388: sqlite3.dll is now installed on Windows independent
230 of Tcl/Tk.
231
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000232- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000233 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +0000235Tests
236-----
237
238- Call os.waitpid() at the end of tests that spawn child processes in order
239 to minimize resources (zombies).

Martin v. Löwis1bf59592006-06-29 18:58:44 +0000241Documentation
242-------------
243
Nick Coghlan2d792252006-07-06 13:47:18 +0000244- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
245 documentation for the warnings module.

256Core and builtins
257-----------------
258
Georg Brandla56b9152006-06-19 06:35:54 +0000259- Patch #1507676: Error messages returned by invalid abstract object operations
260 (such as iterating over an integer) have been improved and now include the
261 type of the offending object to help with debugging.
262
Brett Cannonea3912b2006-06-13 21:46:41 +0000263- Bug #992017: A classic class that defined a __coerce__() method that returned
264 its arguments swapped would infinitely recurse and segfault the interpreter.
265
Neal Norwitz909eb122006-06-12 02:13:21 +0000266- Fix the socket tests so they can be run concurrently.
267
Neal Norwitzb9845e72006-06-12 02:11:18 +0000268- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000269 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000270
Brett Cannon22565aa2006-06-09 22:31:23 +0000271- Bug #532646: object.__call__() will continue looking for the __call__
272 attribute on objects until one without one is found. This leads to recursion
273 when you take a class and set its __call__ attribute to an instance of the
274 class. Originally fixed for classic classes, but this fix is for new-style.
275 Removes the infinite_rec_3 crasher.
276
Georg Brandl24250812006-06-09 18:45:48 +0000277- The string and unicode methods startswith() and endswith() now accept
278 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
279
Brett Cannonde3b0522006-06-08 17:00:45 +0000280- Buffer objects, at the C level, never used the char buffer
281 implementation even when the char buffer for the wrapped object was
282 explicitly requested (originally returned the read or write buffer).
283 Now a TypeError is raised if the char buffer is not present but is
284 requested.
285
Georg Brandlddbaa662006-06-04 21:56:52 +0000286- Patch #1346214: Statements like "if 0: suite" are now again optimized
287 away like they were in Python 2.4.
288
Georg Brandlb7c8f542006-05-27 12:30:25 +0000289- Builtin exceptions are now full-blown new-style classes instead of
290 instances pretending to be classes, which speeds up exception handling
291 by about 80% in comparison to 2.5a2.
292
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000293- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
294 Unicode 4.1.
295
Georg Brandlf4ef1162006-05-26 18:03:31 +0000296- Patch #921466: sys.path_importer_cache is now used to cache valid and
297 invalid file paths for the built-in import machinery which leads to
298 fewer open calls on startup.
299
Tim Peters696cf432006-05-24 21:10:40 +0000300- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
301 of-2 bases. The largest speedup is for inputs with about 1000 decimal
302 digits. Conversion from non-power-of-2 bases remains quadratic-time in
303 the number of input digits (it was and remains linear-time for bases
304 2, 4, 8, 16 and 32).
305
Tim Petersb713ec22006-05-23 18:45:30 +0000306- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
307 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
308 an integer close to ``sys.maxint``. This was repaired by patch
309 #1335972, which also gives a nice speedup.
310
Richard Jonescebbefc2006-05-23 18:28:17 +0000311- Patch #1337051: reduced size of frame objects.
312
313- PyErr_NewException now accepts a tuple of base classes as its
314 "base" parameter.
315
Richard Jones7c88dcc2006-05-23 10:37:38 +0000316- Patch #876206: function call speedup by retaining allocated frame
317 objects.
318
Georg Brandl7b90e162006-05-18 07:01:27 +0000319- Bug #1462152: file() now checks more thoroughly for invalid mode
320 strings and removes a possible "U" before passing the mode to the
321 C library function.
322
Neal Norwitz1004a532006-05-15 07:17:23 +0000323- Patch #1488312, Fix memory alignment problem on SPARC in unicode
324
Neal Norwitz373f0a72006-05-15 07:04:36 +0000325- Bug #1487966: Fix SystemError with conditional expression in assignment
326
Martin v. Löwis879768d2006-05-11 13:28:43 +0000327- WindowsError now has two error code attributes: errno, which carries
328 the error values from errno.h, and winerror, which carries the error
329 values from winerror.h. Previous versions put the winerror.h values
330 (from GetLastError()) into the errno attribute.
331
Martin v. Löwis77736712006-05-04 05:51:03 +0000332- Patch #1475845: Raise IndentationError for unexpected indent.
333
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000334- Patch #1479181: split open() and file() from being aliases for each other.
335
Tim Peters44bd9862006-06-01 13:49:23 +0000336- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
337 methods were always silently ignored by dictionaries when comparing keys.
338 They are now passed through (except when using the C API function
339 ``PyDict_GetItem()``, whose semantics did not change).
340
341- Bug #1456209: In some obscure cases it was possible for a class with a
342 custom ``__eq__()`` method to confuse dict internals when class instances
343 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
344 No, you don't have any code that did this ;-)

Trent Mick960a3f82006-06-28 20:30:41 +0000349- Bug #1295808: expat symbols should be namespaced in pyexpat
350
351- Patch #1462338: Upgrade pyexpat to expat 2.0.0
352
Brett Cannon6ee7d012006-06-08 16:23:04 +0000353- Change binascii.hexlify to accept a read-only buffer instead of only a char
354 buffer and actually follow its documentation.
355
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000356- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
357
Nick Coghlanc649ec52006-05-29 12:43:05 +0000358- Patch #1478788 (modified version): The functional extension module has
359 been renamed to _functools and a functools Python wrapper module added.
360 This provides a home for additional function related utilities that are
361 not specifically about functional programming. See PEP 309.
362
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000363- Patch #1493701: performance enhancements for struct module.
364
Georg Brandl378d5922006-05-17 14:26:50 +0000365- Patch #1490224: time.altzone is now set correctly on Cygwin.
366
Georg Brandl8d3342b2006-05-16 07:38:27 +0000367- Patch #1435422: zlib's compress and decompress objects now have a
368 copy() method.
369
Andrew MacIntyre92913322006-06-13 15:04:24 +0000370- Patch #1454481: thread stack size is now tunable at runtime for thread
371 enabled builds on Windows and systems with Posix threads support.
372
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000373- On Win32, os.listdir now supports arbitrarily-long Unicode path names
374 (up to the system limit of 32K characters).
375
376- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
377 As a result, these functions now raise WindowsError instead of OSError.
378
Tim Peters7a822da2006-05-25 21:50:17 +0000379- ``time.clock()`` on Win64 should use the high-performance Windows
380 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
381 Windows platforms).
382
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000383- Calling Tk_Init twice is refused if the first call failed as that
384 may deadlock.
385
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000386- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
387 accept it without potentially using an uninitialized pointer.
388
389- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
390 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
391 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000392
Gregory P. Smith372b5832006-06-05 18:48:21 +0000393- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000394 [pybsddb project SF patch number 1466734]
395
Gregory P. Smith372b5832006-06-05 18:48:21 +0000396- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
397 parameter is supplied. [SF pybsddb bug #1477863]
398
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000399- bsddb: the __len__ method of a DB object has been fixed to return correct
400 results. It could previously incorrectly return 0 in some cases.
401 Fixes SF bug 1493322 (pybsddb bug 1184012).
402
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000403- bsddb: the bsddb.dbtables Modify method now raises the proper error and
404 aborts the db transaction safely when a modifier callback fails.
405 Fixes SF python patch/bug #1408584.
406
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000407- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000408 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000409 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
410 database calls that would previously deadlock. [SF python bug #775414]
411
Vinay Sajip28e57612006-07-01 10:45:20 +0000412- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000413
Walter Dörwald4994d952006-06-19 08:07:50 +0000414- Patch #1506645: add Python wrappers for the curses functions

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000420- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
421 functions.
422
Martin v. Löwis3798da02006-06-17 18:44:27 +0000423- Patch #812986: Update turtle output even if not tracing.
424
Vinay Sajip28e57612006-07-01 10:45:20 +0000425- Patch #1494750: Destroy master after deleting children in

427
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000428- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
429
Martin v. Löwis337487e2006-06-17 09:15:14 +0000430- Patch #763580: Add name and value arguments to Tkinter variable
431 classes.
432
Georg Brandl83cc0d02006-06-14 08:50:03 +0000433- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
434 mime.types file for determining MIME types.
435
Georg Brandl2605ca82006-06-14 06:08:31 +0000436- Bug #1339007: Shelf objects now don't raise an exception in their
437 __del__ method when initialization failed.
438
Martin v. Löwisd8251432006-06-14 05:21:04 +0000439- Patch #1455898: The MBCS codec now supports the incremental mode for
440 double-byte encodings.
441
Tim Peters43898b42006-06-14 04:09:25 +0000442- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
443 guarantee that adjacent triples in the return list always describe
444 non-adjacent blocks. Previously, a pair of matching blocks could end
445 up being described by multiple adjacent triples that formed a partition
446 of the matching pair.
447
Greg Ward0e0c9f42006-06-11 16:24:11 +0000448- Bug #1498146: fix optparse to handle Unicode strings in option help,
449 description, and epilog.
450
Greg Wardd1c797e2006-06-11 14:42:41 +0000451- Bug #1366250: minor optparse documentation error.
452
Greg Ward7f547402006-06-11 00:40:49 +0000453- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
454 clarify docs.
455
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000456- The wsgiref package has been added to the standard library.
457
Nick Coghlan676725d2006-06-08 13:54:49 +0000458- The functions update_wrapper() and wraps() have been added to the functools
459 module. These make it easier to copy relevant metadata from the original
460 function when writing wrapper functions.
461
Tim Petersd6a9eef2006-06-05 01:48:21 +0000462- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
463 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000464
Martin v. Löwis3f767792006-06-04 19:36:28 +0000465- Patch #1359618: Speed up charmap encoder by using a trie structure
466 for lookup.
467
Tim Petersd609b1a2006-06-02 23:22:51 +0000468- The functions in the ``pprint`` module now sort dictionaries by key
469 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
470 if and only if its display required more than one line, although that
471 wasn't documented. The new behavior increases predictability; e.g.,
472 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
473
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000474- Patch #1497027: try HTTP digest auth before basic auth in urllib2
475 (thanks for J. J. Lee).
476
Georg Brandl2b330372006-05-28 20:23:12 +0000477- Patch #1496206: improve urllib2 handling of passwords with respect to
478 default HTTP and HTTPS ports.
479
George Yoshidaf3c65de2006-05-28 16:39:09 +0000480- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
481
Bob Ippolito7298f272006-05-23 18:43:47 +0000482- Patch #1281707: speed up gzip.readline.
483
Georg Brandlb89316f2006-05-17 15:51:16 +0000484- Patch #1180296: Two new functions were added to the locale module:
485 format_string() to get the effect of "format % items" but locale-aware,
486 and currency() to format a monetary number with currency sign.
487
Georg Brandle3a25832006-05-17 14:56:04 +0000488- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
489 and several features added, such as speed and geometry control.
490
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000491- Patch #1488881: add support for external file objects in bz2 compressed
492 tarfiles.
493
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000494- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
495 stdout arguments, making it possible to redirect input and output
496 for remote debugging.
497
498- Patch #1484695: Update the tarfile module to version 0.8. This fixes
499 a couple of issues, notably handling of long file names using the
500 GNU LONGNAME extension.
501
502- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
503 new flag when ``name`` is already the name of an option flag.
504
505- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
506 package.
507
508- Patch #1472854: make the rlcompleter.Completer class usable on non-
509 UNIX platforms.
510
511- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000513- Bug #1472827: correctly escape newlines and tabs in attribute values in

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000544What's New in Python 2.5 alpha 2?
545=================================
546
547*Release date: 27-APR-2006*
548
549Core and builtins
550-----------------
551
Thomas Heller1b046642006-04-18 18:51:06 +0000552- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
553 by converting these apis from macros into exported functions again:
554
555 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
556 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
557 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
558 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
559 PyRun_String Py_CompileString
560
Martin v. Löwis45294a92006-04-18 06:24:08 +0000561- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
562
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000563- All uses of PyStructSequence_InitType have been changed to initialize
564 the type objects only once, even if the interpreter is initialized
565 multiple times.
566
Neal Norwitz61546162006-04-14 05:20:28 +0000567- Bug #1454485, array.array('u') could crash the interpreter. This was
568 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
569 to unicode when it didn't make sense. 'u#' now requires a unicode string.
570
571- Py_UNICODE is unsigned. It was always documented as unsigned, but
572 due to a bug had a signed value in previous versions.
573
Tim Peters3a5e8b12006-04-11 01:44:07 +0000574- Patch #837242: ``id()`` of any Python object always gives a positive
575 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
576 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000577 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000578 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000579
Tim Peters3a5e8b12006-04-11 01:44:07 +0000580 def __hash__(self):
581 return id(self) # WRONG
582
583 because a hash result must be a (short) Python int but it was always
584 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000585 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000586 was always usable as a hash value before this patch. That's no longer
587 necessarily so.
588
589- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000590 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000591 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000592 #1454844)
593
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000594- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
595 involving generators that have paused outside of any ``try`` or ``with``
596 blocks. (In 2.5a1, a paused generator that was part of a reference
597 cycle could not be garbage collected, regardless of whether it was
598 paused in a ``try`` or ``with`` block.)

615 a temporary db (file=None) with the 'n' flag to truncate on open.
616
617- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
618 as older versions cause excessive test failures.

Peter Astrand7d1d4362006-07-14 14:04:45 +0000626- Bug #1223937: subprocess.CalledProcessError reports the exit status
627 of the process using the returncode attribute, instead of
628 abusing errno.
629
Tim Peters711bf302006-04-25 03:31:36 +0000630- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
631 a doctest to be skipped (the code is not run, and the expected output
632 or exception is ignored).
633
Nick Coghlanda2268f2006-04-24 04:37:15 +0000634- Fixed contextlib.nested to cope with exceptions being raised and
635 caught inside exit handlers.
636
Greg Wardab05edc2006-04-23 03:47:58 +0000637- Updated optparse module to Optik 1.5.1 (allow numeric constants in
638 hex, octal, or binary; add ``append_const`` action; keep going if
639 gettext cannot be imported; added ``OptionParser.destroy()`` method;
640 added ``epilog`` for better help generation).
641
Tim Peters21fbd572006-04-21 21:18:10 +0000642- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
643 called from a thread spawned as a side effect of importing a module.
644
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000645- The pydoc module now supports documenting packages contained in
646 .zip or .egg files.
647
648- The pkgutil module now has several new utility functions, such
649 as ``walk_packages()`` to support working with packages that are either
650 in the filesystem or zip files.
651
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000652- The mailbox module can now modify and delete messages from
653 mailboxes, in addition to simply reading them. Thanks to Gregory
654 K. Johnson for writing the code, and to the 2005 Google Summer of
655 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000656
Tim Petersc7605f22006-04-17 21:12:33 +0000657- The ``__del__`` method of class ``local`` in module ``_threading_local``
658 returned before accomplishing any of its intended cleanup.
659

665
Anthony Baxtere29002c2006-04-12 12:07:31 +0000666- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
667 Windows. Bug #1469163.
668
Phillip J. Eby47032112006-04-11 01:07:43 +0000669- The warnings, linecache, inspect, traceback, site, and doctest modules
670 were updated to work correctly with modules imported from zipfiles or
671 via other PEP 302 __loader__ objects.
672
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000673- Patch #1467770: Reduce usage of subprocess._active to processes which
674 the application hasn't waited on.
675
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000676- Patch #1462222: Fix Tix.Grid.
677
Neal Norwitza31bf182006-04-09 03:35:43 +0000678- Fix exception when doing glob.glob('anything*/')
679
Skip Montanaro262fb922006-04-21 02:31:07 +0000680- The pstats.Stats class accepts an optional stream keyword argument to
681 direct output to an alternate file-like object.
682
Anthony Baxter51bcb682006-04-05 14:51:42 +0000683Build
684-----
685
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000686- The Makefile now has a reindent target, which runs reindent.py on
687 the library.
688
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000689- Patch #1470875: Building Python with MS Free Compiler
690
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000691- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000692
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000693- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
694 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000695 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000696 CXX from --with-cxx-main, see description in README.
697
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000698- Patch #1429775: Link extension modules with the shared libpython.
699
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000700- Fixed a libffi build problem on MIPS systems.
701
Tim Peters8931ff12006-05-13 23:28:20 +0000702- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
703 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
704 and "%zu" for unsigned integers of type ``size_t``.
705
Anthony Baxter51bcb682006-04-05 14:51:42 +0000706Tests
707-----
708
Nick Coghlanda2268f2006-04-24 04:37:15 +0000709- test_contextlib now checks contextlib.nested can cope with exceptions
710 being raised and caught inside exit handlers.
711
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000712- test_cmd_line now checks operation of the -m and -c command switches
713
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000714- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
715 it separately and by hand. It also wasn't cleaning up its changes to
716 the current Decimal context.
717
Thomas Woutersabd08882006-04-26 15:53:30 +0000718- regrtest.py now has a -M option to run tests that test the new limits of
719 containers, on 64-bit architectures. Running these tests is only sensible
720 on 64-bit machines with more than two gigabytes of memory. The argument
721 passed is the maximum amount of memory for the tests to use.
722
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +0000723Tools

Anthony Baxter51bcb682006-04-05 14:51:42 +0000729Documentation
730-------------
731
Tim Petersb06d28c2006-05-12 01:57:59 +0000732- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
733
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000734- PEP 343: Added Context Types section to the library reference
735 and attempted to bring other PEP 343 related documentation into
736 line with the implementation and/or python-dev discussions.
737
Tim Peters8dc73d22006-04-24 02:03:16 +0000738- Bug #1337990: clarified that ``doctest`` does not support examples
739 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000742What's New in Python 2.5 alpha 1?
743=================================
744
Anthony Baxterebed3f62006-04-03 15:03:44 +0000745*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000746
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000747Core and builtins
748-----------------
749
Nick Coghlan43832302006-04-23 17:04:07 +0000750- PEP 338: -m command line switch now delegates to runpy.run_module
751 allowing it to support modules in packages and zipfiles
752
Martin v. Löwisc661b882006-04-20 04:54:23 +0000753- On Windows, .DLL is not an accepted file name extension for
754 extension modules anymore; extensions are only found if they
755 end in .PYD.
756
Martin v. Löwisea62d252006-04-03 10:56:49 +0000757- Bug #1421664: sys.stderr.encoding is now set to the same value as
758 sys.stdout.encoding.
759
Neal Norwitz92e212f2006-04-03 04:48:37 +0000760- __import__ accepts keyword arguments.
761
Georg Brandlccadf842006-03-31 18:54:53 +0000762- Patch #1460496: round() now accepts keyword arguments.
763
Anthony Baxter262c00a2006-03-30 10:53:17 +0000764- Fixed bug #1459029 - unicode reprs were double-escaped.
765
Hye-Shik Changd478f342006-03-23 12:32:36 +0000766- Patch #1396919: The system scope threads are reenabled on FreeBSD
767 5.4 and later versions.
768
Neal Norwitze98ccf62006-03-23 05:39:47 +0000769- Bug #1115379: Compiling a Unicode string with an encoding declaration
770 now gives a SyntaxError.
771
Georg Brandlabd1ff82006-03-18 07:59:59 +0000772- Previously, Python code had no easy way to access the contents of a
773 cell object. Now, a ``cell_contents`` attribute has been added
774 (closes patch #1170323).
775
Tim Peterscf79aac2006-03-16 01:14:46 +0000776- Patch #1123430: Python's small-object allocator now returns an arena to
777 the system ``free()`` when all memory within an arena becomes unused
778 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
779 freed. Some applications will see a drop in virtual memory size now,
780 especially long-running applications that, from time to time, temporarily
781 use a large number of small objects. Note that when Python returns an
782 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000783 platform C library will in turn return that memory to the operating system.
784 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000785 appears to be effective at least on Microsoft C and gcc-based systems.
786 Thanks to Evan Jones for hard work and patience.
787
Georg Brandl533ff6f2006-03-08 18:09:27 +0000788- Patch #1434038: property() now uses the getter's docstring if there is
789 no "doc" argument given. This makes it possible to legitimately use
790 property() as a decorator to produce a read-only property.
791
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000792- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
793 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
794 of requiring an int or long in slicing and a few other contexts, enabling
795 other objects (e.g. Numeric Python's integers) to be used as slice indices.
796
Neal Norwitz995acdf2006-03-07 05:01:00 +0000797- Fixed various bugs reported by Coverity's Prevent tool.
798
Brett Cannonbf364092006-03-01 04:25:17 +0000799- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
800 new exception base class, BaseException, which has a new message attribute.
801 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
802 Raising a string exception now raises a DeprecationWarning.
803
Thomas Woutersfb609f42006-02-28 16:37:25 +0000804- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
805 explicitly relative, using 'from .module import name' to mean 'from the same
806 package as this module is in. Imports without dots still default to the
807 old relative-then-absolute, unless 'from __future__ import
808 absolute_import' is used.
809
Brett Cannona7446e32006-02-27 23:39:10 +0000810- Properly check if 'warnings' raises an exception (usually when a filter set
811 to "error" is triggered) when raising a warning for raising string
812 exceptions.
813
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000814- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000815 The name was removed from Include/code.h.
816
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000817- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000818
Guido van Rossum1968ad32006-02-25 22:38:04 +0000819- Patch 1433928:
820 - The copy module now "copies" function objects (as atomic objects).
821 - dict.__getitem__ now looks for a __missing__ hook before raising
822 KeyError.
823
Tim Peters84ef21c2006-02-28 20:39:06 +0000824- PEP 343: with statement implemented. Needs ``from __future__ import
825 with_statement``. Use of 'with' as a variable will generate a warning.
826 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000827 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000828 The following objects have __context__ methods:
829 - The built-in file type.
830 - The thread.LockType type.
831 - The following types defined by the threading module:
832 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
833 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000834
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000835- Fix the encodings package codec search function to only search
836 inside its own package. Fixes problem reported in patch #1433198.
837
838 Note: Codec packages should implement and register their own
839 codec search function. PEP 100 has the details.
840
Tim Peters9ea89d22006-06-04 03:26:02 +0000841- PEP 353: Using ``Py_ssize_t`` as the index type.
842
843- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
844 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
845 now allow Python to make use of memory blocks exceeding 2**32 bytes for
846 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
847 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000848
Neal Norwitzfc76d632006-01-10 06:03:13 +0000849- Patch #1400181, fix unicode string formatting to not use the locale.
850 This is how string objects work. u'%f' could use , instead of .
851 for the decimal point. Now both strings and unicode always use periods.
852
Neal Norwitz671b9e32006-01-09 07:07:12 +0000853- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
854 configure would break checking curses.h.
855
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000856- Bug #959576: The pwd module is now builtin. This allows Python to be
857 built on UNIX platforms without $HOME set.
858
Neal Norwitzc10978f2005-12-19 06:07:16 +0000859- Bug #1072182, fix some potential problems if characters are signed.
860
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000861- Bug #889500, fix line number on SyntaxWarning for global declarations.
862
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000863- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
864
Neal Norwitze7214a12005-12-18 05:03:17 +0000865- Support for converting hex strings to floats no longer works.
866 This was not portable. float('0x3') now raises a ValueError.
867
Barry Warsaw2a38a862005-12-18 01:27:35 +0000868- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000869 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000870 is now displayed in interactive prompt banner.
871
Georg Brandlfa166682005-12-17 21:45:17 +0000872- Implementation of PEP 341 - Unification of try/except and try/finally.
873 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000874 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000875
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000876- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
877 now encodes backslash correctly.
878
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000879- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
880
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000881- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000882 and long longs.
883
Neal Norwitz67715f02005-11-09 06:59:35 +0000884- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000885 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000886 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000887
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000888- Replaced most Unicode charmap codecs with new ones using the
889 new Unicode translate string feature in the builtin charmap
890 codec; the codecs were created from the mapping tables available
891 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
892 encodings now include a mapping for the Apple logo)
893
Tim Peterse3547fd2005-12-16 23:13:57 +0000894- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000895
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000896- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000897
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000898- A new AST parser implementation was completed. The abstract
899 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000900 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000901
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000902- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000903 The following code now raises a SyntaxError: foo(a = i for i in range(10))
904
Neal Norwitz708e51a2005-10-03 04:48:15 +0000905- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
906
Neal Norwitz11bd1192005-10-03 00:54:56 +0000907- SF Bug #887946: fix segfault when redirecting stdin from a directory.
908 Provide a warning when a directory is passed on the command line.
909
Neal Norwitz40d37812005-10-02 01:48:49 +0000910- Fix segfault with invalid coding.
911
912- SF bug #772896: unknown encoding results in MemoryError.
913
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000914- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000915 supported a __len__() method which evaluated to False when the iterator
916 was empty.
917
Guido van Rossum630db602005-09-20 18:49:54 +0000918- On 64-bit platforms, when __len__() returns a value that cannot be
919 represented as a C int, raise OverflowError.
920
Skip Montanarof8948ca2005-09-19 03:54:46 +0000921- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000922 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000923
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000924- SF bug #893549: parsing keyword arguments was broken with a few format
925 codes.
926
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000927- Changes donated by Elemental Security to make it work on AIX 5.3
928 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
929 bug #105470: test_pwd fails on 64bit system (Opteron).
930
Guido van Rossum539c6622005-09-14 17:49:54 +0000931- Changes donated by Elemental Security to make it work on HP-UX 11 on
932 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
933
Georg Brandl4550b8d2005-08-26 06:43:52 +0000934- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000935 (fixes bug #1119418).
936
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000937- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
938
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000939- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
940 exceptions that cause a function to exit.
941
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000942- The implementation of set() and frozenset() was revised to use its
943 own internal data structure. Memory consumption is reduced by 1/3
944 and there are modest speed-ups as well. The API is unchanged.
945
Tim Petersde7990b2005-07-17 23:45:23 +0000946- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
947
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000948- SF bug #1229429: PyObject_CallMethod failed to decrement some
949 reference counts in some error exit cases.
950
Tim Petersecc6e6a2005-07-10 22:30:55 +0000951- SF bug #1185883: Python's small-object memory allocator took over
952 a block managed by the platform C library whenever a realloc specified
953 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000954 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000955 portable way to copy data from the C-managed block into Python's
956 small-object space without risking a memory fault. Python's small-object
957 realloc now leaves such blocks under the control of the platform C
958 realloc.
959
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000960- SF bug #1232517: An overflow error was not detected properly when
961 attempting to convert a large float to an int in os.utime().
962
Raymond Hettinger3296e692005-06-29 23:29:56 +0000963- SF bug #1224347: hex longs now print with lowercase letters just
964 like their int counterparts.
965
Michael W. Hudson188d4362005-06-20 16:52:57 +0000966- SF bug #1163563: the original fix for bug #1010677 ("thread Module
967 Breaks PyGILState_Ensure()") broke badly in the case of multiple
968 interpreter states; back out that fix and do a better job (see
969 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
970 for a longer write-up of the problem).
971
Michael W. Hudsondf888462005-06-03 14:41:55 +0000972- SF patch #1180995: marshal now uses a binary format by default when
973 serializing floats.
974
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000975- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
976 the routines that promise to produce IEEE 754 binary representations
977 of floats now simply copy bytes around.
978
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000979- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
980 278.
981
Brett Cannonc3647ac2005-04-26 03:45:26 +0000982- patch #1109424: int, long, float, complex, and unicode now check for the
983 proper magic slot for type conversions when subclassed. Previously the
984 magic slot was ignored during conversion. Semantics now match the way
985 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000986 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000987 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000988 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000989
Barry Warsawc8d907c2005-04-19 23:43:40 +0000990- Descriptors defined in C with a PyGetSetDef structure, where the setter is
991 NULL, now raise an AttributeError when attempting to set or delete the
992 attribute. Previously a TypeError was raised, but this was inconsistent
993 with the equivalent pure-Python implementation.
994
Michael W. Hudson774479c2005-04-18 08:46:17 +0000995- It is now safe to call PyGILState_Release() before
996 PyEval_InitThreads() (note that if there is reason to believe there
997 are multiple threads around you still must call PyEval_InitThreads()
998 before using the Python API; this fix is for extension modules that
999 have no way of knowing if Python is multi-threaded yet).
1000
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001001- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1002 disabled caused a crash.
1003
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001004- Bug #1165306: instancemethod_new allowed the creation of a method
1005 with im_class == im_self == NULL, which caused a crash when called.
1006
Tim Petersecc6e6a2005-07-10 22:30:55 +00001007- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001008 fixes the crash seen in bug #1165761
1009
Raymond Hettinger96229b12005-03-11 06:49:40 +00001010- Added two new builtins, any() and all().
1011
Brett Cannon409d8f22005-03-05 06:47:57 +00001012- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001013 (e.g., ``class C(): pass`` is no longer a syntax error).
1014 Patch #1176012 added support to the 'parser' module and 'compiler' package
1015 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001016
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001017- Patch #1115086: Support PY_LONGLONG in structmember.
1018
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001019- Bug #1155938: new style classes did not check that __init__() was
1020 returning None.
1021
Tim Petersecc6e6a2005-07-10 22:30:55 +00001022- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001023 ('\') with a specific error message.
1024
Martin v. Löwisff232d72005-03-03 09:24:38 +00001025- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1026
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001027- Bug #1124295: the __name__ attribute of file objects was
1028 inadvertently made inaccessible in restricted mode.
1029
Tim Petersecc6e6a2005-07-10 22:30:55 +00001030- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001031 an ferror() call.
1032
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001033- min() and max() now support key= arguments with the same meaning as in
1034 list.sort().
1035
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001036- The peephole optimizer now performs simple constant folding in expressions:
1037 (2+3) --> (5).
1038
Raymond Hettingera422c342005-01-11 03:03:27 +00001039- set and frozenset objects can now be marshalled. SF #1098985.
1040
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001041- Bug #1077106: Poor argument checking could cause memory corruption
1042 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001043
Jeremy Hyltonab630502005-02-04 18:44:06 +00001044- The parser did not complain about future statements in illegal
1045 positions. It once again reports a syntax error if a future
1046 statement occurs after anything other than a doc string.
1047
Neil Schemenauercf52c072005-08-12 17:34:58 +00001048- Change the %s format specifier for str objects so that it returns a
1049 unicode instance if the argument is not an instance of basestring and
1050 calling __str__ on the argument returns a unicode instance.
1051
Tim Petersf4e69282006-02-27 17:15:31 +00001052- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1053 current thread state when the auto-GIL-state machinery knows about
1054 it (since the thread state is being deleted, continuing to remember it
1055 can't help, but can hurt if another thread happens to get created with
1056 the same thread id).
1057
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001058Extension Modules

1075
1076- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1077
1078- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001079 is deprecated. The undocumented re.engine variable no longer exists.

1083
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001084- The unicodedata module was updated to the 4.1 version of the Unicode
1085 database. The 3.2 version is still available as unicodedata.db_3_2_0
1086 for applications that require this specific version (such as IDNA).
1087
Neal Norwitzb62c4332006-03-04 18:35:47 +00001088- The timing module is no longer built by default. It was deprecated
1089 in PEP 4 in Python 2.0 or earlier.
1090
Guido van Rossum1968ad32006-02-25 22:38:04 +00001091- Patch 1433928: Added a new type, defaultdict, to the collections module.
1092 This uses the new __missing__ hook behavior added to dict (see above).
1093
Georg Brandldbd83392006-02-20 09:42:33 +00001094- Bug #854823: socketmodule now builds on Sun platforms even when
1095 INET_ADDRSTRLEN is not defined.
1096
Georg Brandlf4f44152006-02-18 22:29:33 +00001097- Patch #1393157: os.startfile() now has an optional argument to specify
1098 a "command verb" to invoke on the file.
1099

1104 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1105 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1106
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001107- Patch #1422385: The nis module now supports access to domains other
1108 than the system default domain.
1109
Martin v. Löwis14694662006-02-03 12:54:16 +00001110- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1111 are reported, the limit on path name lengths is removed, and stat reports
1112 WindowsError now (instead of OSError).
1113
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001114- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

1189 the request code argument, which results in more C-like behaviour
1190 for large or negative values.
1191
Tim Petersecc6e6a2005-07-10 22:30:55 +00001192- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

1201 available on the platform.
1202
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001203- Bug #1166660: The readline module could segfault if hook functions
1204 were set in a different thread than that which called readline.
1205
Raymond Hettinger4aec61e2005-03-18 21:20:23 +00001206- collections.deque objects now support a remove() method.
1207
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00001208- operator.itemgetter() and operator.attrgetter() now support retrieving
1209 multiple fields. This provides direct support for sorting on multiple
1210 keys (primary, secondary, etc).
1211
Martin v. Löwisb60ae992005-03-08 09:10:29 +00001212- os.access now supports Unicode path names on non-Win32 systems.

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001232- the cPickle module no longer accepts the deprecated None option in the
1233 args tuple returned by __reduce__().
1234
Raymond Hettingerb2594052004-12-05 09:25:51 +00001235- itertools.islice() now accepts None for the start and step arguments.
1236 This allows islice() to work more readily with slices:
1237 islice(s.start, s.stop, s.step)
1238
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001239- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001248- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1249 been renamed to have only a single underscore prefix. This was done to
1250 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001251
Nick Coghlan43832302006-04-23 17:04:07 +00001252- PEP 338: new module runpy defines a run_module function to support
1253 executing modules which provide access to source code or a code object
1254 via the PEP 302 import mechanisms.
1255
Anthony Baxter93f5b932006-04-03 08:05:07 +00001256- The email module's parsedate_tz function now sets the daylight savings
1257 flag to -1 (unknown) since it can't tell from the date whether it should

1264 in attribute values.
1265
Anthony Baxterc51ee692006-04-01 00:57:31 +00001266- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001267 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001268 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001269 module will not be built.
1270
Tim Petersc17976e2006-04-01 00:26:53 +00001271- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1272 aren't officially supported here, and trying to use them will probably
1273 raise an exception some day. But dicts have been allowed, and "mostly
1274 worked", so support for them won't go away without warning.
1275
Georg Brandl338ef7d2006-03-31 18:42:16 +00001276- Bug #1445068: getpass.getpass() can now be given an explicit stream
1277 argument to specify where to write the prompt.
1278
Georg Brandl22ec80b2006-03-31 18:25:44 +00001279- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1286
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001287- Queue.Queue objects now support .task_done() and .join() methods
1288 to make it easier to monitor when daemon threads have completed
1289 processing all enqueued tasks. Patch #1455676.
1290
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001291- popen2.Popen objects now preserve the command in a .cmd attribute.

1294
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001295- email 4.0 package now integrated. This is largely the same as the email 3.0
1296 package that was included in Python 2.3, except that PEP 8 module names are
1297 now used (e.g. mail.message instead of email.Message). The MIME classes
1298 have been moved to a subpackage (e.g. email.mime.text instead of
1299 email.MIMEText). The old names are still supported for now. Several
1300 deprecated Message methods have been removed and lots of bugs have been
1301 fixed. More details can be found in the email package documentation.
1302
Walter Dörwald40108c92006-03-27 08:15:44 +00001303- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1304 (a subclass of tuple) that provides incremental decoders and encoders
1305 (a way to use stateful codecs without the stream API). Python functions
1306 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1307 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1308 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001309
Walter Dörwald067db482006-03-15 22:17:27 +00001310- Patch #1359365: Calling next() on a closed StringIO.String object raises
1311 a ValueError instead of a StopIteration now (like file and cString.String do).
1312 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1313 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001314
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001315- A regrtest option -w was added to re-run failed tests in verbose mode.

1325
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001326- PEP 343: new module contextlib.py defines decorator @contextmanager
1327 and helpful context managers nested() and closing().
1328
Martin v. Löwis415ed932006-02-27 19:56:30 +00001329- The compiler package now supports future imports after the module docstring.
1330

1333
Georg Brandlc98eeed2006-02-19 14:57:47 +00001334- Patch #1215184: FileInput now can be given an opening hook which can

Martin v. Löwis3e865952006-01-24 15:51:21 +00001363 specifications, raises IOErrors when proxies for unsupported protocols
1364 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00001387 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1388 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1389 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1390 Ronald L. Rivest offered this advice for Python:
1391
1392 "The consensus of researchers in this area (at least as
1393 expressed at the NIST Hash Function Workshop 10/31/05),
1394 is that SHA-256 is a good choice for the time being, but
1395 that research should continue, and other alternatives may
1396 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001397
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001398- Added a subset of Fredrik Lundh's ElementTree package. Available

1463 Tkdnd.
1464
Georg Brandl5dbda752005-07-17 20:27:41 +00001465- Bug #1015140: disambiguated the term "article id" in nntplib docs and
1466 docstrings to either "article number" or "message id".
1467
Georg Brandla4a8b822005-07-15 09:13:21 +00001468- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
1469 parameter, but uses the usual "kwargs=None".
1470
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001471- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00001472 Patch #1209527 (Contributed by Connelly).
1473
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00001474- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
1475 to W3C name (404 -> 'Not Found'). RFE #1216944.
1476
Georg Brandl9e43acf2005-07-04 17:16:07 +00001477- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1478 as this can cause problems with apps closing all file descriptors.
1479
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001480- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001481 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00001482

1484
Georg Brandlfbff1bc2005-06-26 21:36:25 +00001485- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
1486 error messages.
1487
Georg Brandl379f99d2005-06-26 21:09:38 +00001488- Bug #1108948: Cookie.py produced invalid JavaScript code.
1489
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001490- The tokenize module now detects and reports indentation errors.
1491 Bug #1224621.
1492
Raymond Hettinger68c04532005-06-10 11:05:19 +00001493- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001494 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001495 the generate_tokens() function now accepts a callable argument that
1496 terminates by raising StopIteration.
1497
Georg Brandl9166e1a2005-06-04 09:20:03 +00001498- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1499
Georg Brandl268e61c2005-06-03 14:28:50 +00001500- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1501 component of the path.
1502
Skip Montanaro174dd222005-05-14 20:54:16 +00001503- Patch #1120353: The xmlrpclib module provides better, more transparent,
1504 support for datetime.{datetime,date,time} objects. With use_datetime set
1505 to True, applications shouldn't have to fiddle with the DateTime wrapper
1506 class at all.
1507
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001508- distutils.commands.upload was added to support uploading distribution
1509 files to PyPI.
1510
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001511- distutils.commands.register now encodes the data as UTF-8 before posting
1512 them to PyPI.
1513
Raymond Hettinger267b8682005-03-27 10:47:39 +00001514- decimal operator and comparison methods now return NotImplemented
1515 instead of raising a TypeError when interacting with other types. This
1516 allows other classes to implement __radd__ style methods and have them
1517 work as expected.
1518
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001519- Bug #1163325: Decimal infinities failed to hash. Attempting to
1520 hash a NaN raised an InvalidOperation instead of a TypeError.
1521
Tim Petersecc6e6a2005-07-10 22:30:55 +00001522- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001523 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1524

Raymond Hettingerbab41432005-02-05 01:31:19 +00001555- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1556
Guido van Rossumd0641422005-02-03 15:01:24 +00001557- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1558 disables recursive traversal through instance attributes, which can
1559 be exploited in various ways.
1560
Tim Peterse3547fd2005-12-16 23:13:57 +00001561- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001562 flags on the HTTP listening socket.
1563
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001564- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1565 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1566
Tim Peterse3547fd2005-12-16 23:13:57 +00001567- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001568 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1569
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001570- Bug #1110478: Revert os.environ.update to do putenv again.
1571
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001572- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1573
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001574- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1575
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001576- Enhancements to the csv module:
1577
1578 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001579 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001580 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001581 + Dialect parameter parsing has been re-implemented to improve error
1582 reporting.
1583 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1584 dictates.
1585 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001586 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001587 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001588 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1589 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001590 + reader now allows \r characters to be quoted (previously it only allowed
1591 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001592 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001593 + Dialect classes passed to the module are no longer instantiated by
1594 the module before being parsed (the former validation scheme required
1595 this, but the mechanism was unreliable).
1596 + The dialect registry now contains instances of the internal
1597 C-coded dialect type, rather than references to python objects.
1598 + the internal c-coded dialect type is now immutable.
1599 + register_dialect now accepts the same keyword dialect specifications
1600 as the reader and writer, allowing the user to register dialects
1601 without first creating a dialect class.
1602 + a configurable limit to the size of parsed fields has been added -
1603 previously, an unmatched quote character could result in the entire
1604 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001605 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001606 the parser field size limit (returning the former limit). The initial
1607 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001608 + A line_num attribute has been added to the reader object, which tracks
1609 the number of lines read from the source iterator. This is not
1610 the same as the number of records returned, as records can span
1611 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001612 + reader and writer objects were not being registered with the cyclic-GC.
1613 This has been fixed.
1614
Brett Cannone6539c42005-01-08 02:43:53 +00001615- _DummyThread objects in the threading module now delete self.__block that is
1616 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1617 lock primitives tend to be limited in number and thus should not be wasted on
1618 a _DummyThread object. Fixes bug #1089632.
1619
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001620- The imghdr module now detects Exif files.
1621
Raymond Hettinger6065d322004-12-20 23:51:53 +00001622- StringIO.truncate() now correctly adjusts the size attribute.
1623 (Bug #951915).
1624
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001625- locale.py now uses an updated locale alias table (built using
1626 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1627 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001628 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001629
Raymond Hettinger3557f422004-12-07 12:02:02 +00001630- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1631
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001632- the pickle module no longer accepts the deprecated None option in the
1633 args tuple returned by __reduce__().
1634
Brett Cannon84667c02004-12-07 03:25:18 +00001635- optparse now optionally imports gettext. This allows its use in setup.py.
1636
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001637- the pickle module no longer uses the deprecated bin parameter.
1638
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001639- the shelve module no longer uses the deprecated binary parameter.
1640
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001641- the pstats module no longer uses the deprecated ignore() method.
1642
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001643- the filecmp module no longer uses the deprecated use_statcache argument.
1644
Raymond Hettinger664347b2004-12-04 21:21:53 +00001645- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1646 extended or overridden by subclasses. Formerly, the subclassed method would
1647 be ignored by the rest of the module. (Bug #1078905).
1648
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001649- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001650 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001651
Walter Dörwald36733692004-12-22 12:50:50 +00001652- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1653 once when a size argument is given. This prevents a buffer overflow in the
1654 tokenizer with very long source lines.
1655
Barry Warsaw538561e2006-01-01 21:48:54 +00001656- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1657 immediately after creating the object, without any intervening
1658 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001659
Skip Montanaro05885812005-01-16 20:48:27 +00001660- The reconvert.quote function can now emit triple-quoted strings. The
1661 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001662
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001663- ``UserString.MutableString`` now supports negative indices in
1664 ``__setitem__`` and ``__delitem__``
1665
Greg Ward40407942005-03-05 02:53:17 +00001666- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1667 correctly.
1668
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001669- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1670 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1671 character even if the user has passed a size parameter to get a proper
1672 line ending. Remove the special handling of a "\r\n" that has been split
1673 between two lines.
1674
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001675- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1676 about illegal code points. The codec now supports PEP 293 style error
1677 handlers.
1678
Walter Dörwald78a78b02005-09-01 12:04:29 +00001679- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001680 from the input stream, so that the output is a byte string in the correct
1681 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001682
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001683- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1684 considering it exactly like a '*'.
1685
Walter Dörwald007f8df2005-10-09 19:42:27 +00001686- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1687 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001688
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001689- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1690
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001691- Patch #1413711: Certain patterns of differences were making difflib
1692 touch the recursion limit.
1693
Walter Dörwald58917a62006-03-31 15:26:22 +00001694- Bug #947906: An object oriented interface has been added to the calendar
1695 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001696 called as a script (e.g. via ``python -mcalendar``). Localized month and
1697 weekday names can be ouput (even if an exotic encoding is used) using
1698 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001699

Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001710- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1711
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001712- Patch #881820: look for openpty and forkpty also in libbsd.
1713
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001714- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1715 The zlib module is now builtin on Windows.
1716
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001717- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1718
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001719- Bug #1189330: configure did not correctly determine the necessary
1720 value of LINKCC if python was built with GCC 4.0.
1721
Trent Mick8321b422005-07-26 02:29:21 +00001722- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1723 vulnerability in zlib 1.2.1 and 1.2.2.
1724
Brett Cannon08cd5982005-04-24 22:26:38 +00001725- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1726 flags that change binary compatibility. Changes were also made to
1727 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001728 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001729
Bob Ippolitoed233462005-03-29 13:47:59 +00001730- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1731 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1732 no longer exists). This configure patch makes things right.
1733
Martin v. Löwise2713be2005-03-08 15:03:08 +00001734- Bug #1158607: Build with --disable-unicode again.
1735
Brett Cannon46d96232005-02-16 00:07:19 +00001736- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1737 defined. Discovered as a result of not being able to build on OS X.
1738
Brett Cannon516592f2004-12-07 00:42:59 +00001739- setup.py now uses the directories specified in LDFLAGS using the -L option
1740 and in CPPFLAGS using the -I option for adding library and include
1741 directories, respectively, for compiling extension modules against. This has
1742 led to the core being compiled using the values in CPPFLAGS. It also removes
1743 the need for the special-casing of both DarwinPorts and Fink for darwin since
1744 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1745 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1746 Fink, ``-I/opt/local/include`` for DarwinPorts).
1747
Brett Cannon43802422005-02-10 20:48:03 +00001748- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1749 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1750 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1751 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001753C API
1754-----
1755
Tim Petersc9d78aa2006-03-26 23:27:58 +00001756- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1757 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1758 is obtained via the ``PyObject_`` family, it must be released via the
1759 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1760 always been officially true, but when Python's small-object allocator was
1761 introduced, an attempt was made to cater to a few extension modules
1762 discovered at the time that obtained memory via ``PyObject_New`` but
1763 released it via ``PyMem_DEL``. It's years later, and if such code still
1764 exists it will fail now (probably with segfaults, but calling wrong
1765 low-level memory management functions can yield many symptoms).
1766
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001767- Added a C API for set and frozenset objects.
1768
Raymond Hettinger66517482004-12-03 11:45:13 +00001769- Removed PyRange_New().
1770
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001771- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1772 mapping argument now. This string is used as a mapping table. Byte values
1773 greater than the length of the string and 0xFFFE are treated as undefined
1774 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00001780- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001781
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001782- Patch #1276356: New resource "urlfetch" is implemented. This enables
1783 even impatient people to run tests that require remote files.
