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.

40-------
41
Martin v. Löwis0b483032006-07-25 09:53:12 +000042- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
43
Georg Brandlc13c34c2006-07-24 14:09:56 +000044- Patch #1515343: Fix printing of deprecated string exceptions with a
45 value in the traceback module.
46
Greg Ward48fae7a2006-07-23 16:05:51 +000047- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
48
Martin v. Löwis426f4a12006-07-18 17:46:31 +000049- Patch #1524429: Use repr() instead of backticks in Tkinter again.
50
Brett Cannoncaebe222006-07-18 04:41:36 +000051- Bug #1520914: Change time.strftime() to accept a zero for any position in its
52 argument tuple. For arguments where zero is illegal, the value is forced to
53 the minimum value that is correct. This is to support an undocumented but
54 common way people used to fill in inconsequential information in the time
55 tuple pre-2.4.
56
Bob Ippolito5ea4bf12006-07-15 16:53:15 +000057- Patch #1220874: Update the binhex module for Mach-O.
58
Barry Warsawb110bad2006-07-21 14:51:07 +000059- The email package has improved RFC 2231 support, specifically for
60 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
61 (name*0=<blah>) parameter continuations. This may change the types of
62 values returned from email.message.Message.get_param() and friends.
63 Specifically in some cases where non-encoded continuations were used,
64 get_param() used to return a 3-tuple of (None, None, string) whereas now it
65 will just return the string (since non-encoded continuations don't have
66 charset and language parts).
67
68 Also, whereas % values were decoded in all parameter continuations, they are
69 now only decoded in encoded parameter parts.

Neal Norwitza1f10902006-07-12 07:28:29 +000071Extension Modules
72-----------------
73
Martin v. Löwisbda0dde2006-07-24 10:26:33 +000074- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
75
Thomas Hellerce049a02006-07-14 17:51:14 +000076- Patch #1521817: Index range checking on ctypes arrays containing
77 exactly one element enabled again. This allows iterating over these
78 arrays, without the need to check the array size before.
79
Thomas Heller6e1ad2e2006-07-13 17:05:13 +000080- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +000081 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +000082 /dev/null in certain cases; this is now fixed.
83
Thomas Heller47d7a062006-07-12 08:43:47 +000084- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
85 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +000086
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +000087- Because of a misspelled preprocessor symbol, ctypes was always
88 compiled without thread support; this is now fixed.
89
Brett Cannonf23ad3d2006-07-25 17:32:20 +000090Tests
91-----
92
93- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
94 how long the test file should take to play. Now accepts taking 2.93 secs
95 (exact time) +/- 10% instead of the hard-coded 3.1 sec.

103Core and builtins
104-----------------
105
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000106- Bug #1441486: The literal representation of -(sys.maxint - 1)
107 again evaluates to a int object, not a long.
108
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000109- Bug #1501934: The scope of global variables that are locally assigned
110 using augmented assignment is now correctly determined.
111
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000112- Bug #927248: Recursive method-wrapper objects can now safely
113 be released.
114
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000115- Bug #1417699: Reject locale-specific decimal point in float()
116 and atof().
117
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000118- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
119 omit a default "error" argument for NULL pointer. This allows
120 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000121
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000122- Bug #1519018: 'as' is now validated properly in import statements.
123
Neal Norwitz28746ab2006-07-09 22:14:42 +0000124- On 64 bit systems, int literals that use less than 64 bits are
125 now ints rather than longs.
126
Neal Norwitzed657552006-07-10 00:04:44 +0000127- Bug #1512814, Fix incorrect lineno's when code at module scope
128 started after line 256.
129
Tim Peters32a83612006-07-10 21:08:24 +0000130- New function ``sys._current_frames()`` returns a dict mapping thread
131 id to topmost thread stack frame. This is for expert use, and is
132 especially useful for debugging application deadlocks. The functionality
133 was previously available in Fazal Majid's ``threadframe`` extension
134 module, but it wasn't possible to do this in a wholly threadsafe way from
135 an extension.
136

141
Tim Peters32a83612006-07-10 21:08:24 +0000142- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000143 environment variable to be set in order to the SDK environment
144 for finding the compiler, include files, etc.
145
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000146- Bug #1515998: Properly generate logical ids for files in bdist_msi.
147
Nick Coghlan2d792252006-07-06 13:47:18 +0000148- warnings.py now ignores ImportWarning by default
149
Thomas Woutersadd19112006-07-05 11:03:49 +0000150- string.Template() now correctly handles tuple-values. Previously,
151 multi-value tuples would raise an exception and single-value tuples would
152 be treated as the value they contain, instead.
153
Martin v. Löwisede77f52006-07-03 13:01:35 +0000154- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
155 even if some data are received.
156
Martin v. Löwis45482392006-07-03 12:28:58 +0000157- Bug #1267547: Put proper recursive setup.py call into the

161 degrees and radians.
162
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000163- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000164 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000165
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000166- Bug #1514703: Only setup canvas window in turtle when the canvas
167 is created.
168
Martin v. Löwis7596e832006-07-01 15:33:37 +0000169- Bug #1513223: .close() of a _socketobj now releases the underlying
170 socket again, which then gets closed as it becomes unreferenced.
171
Fred Drake10497c82006-06-29 02:57:48 +0000172- Bug #1504333: Make sgmllib support angle brackets in quoted
173 attribute values.
174
175- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
176 sgmllib ('[' and ']' were not accepted).
177
Georg Brandl1be63af2006-06-28 20:23:25 +0000178- Fix a bug in the turtle module's end_fill function.
179
Brett Cannon53ab5b72006-06-22 16:49:14 +0000180- Bug #1510580: The 'warnings' module improperly required that a Warning
181 category be either a types.ClassType and a subclass of Warning. The proper
182 check is just that it is a subclass with Warning as the documentation states.
183
Georg Brandlad29e632006-06-21 17:45:17 +0000184- The compiler module now correctly compiles the new try-except-finally
185 statement (bug #1509132).
186
Neal Norwitz60373cd2006-06-22 06:30:50 +0000187- The wsgiref package is now installed properly on Unix.
188
Vinay Sajip28e57612006-07-01 10:45:20 +0000189- A bug was fixed in logging.config.fileConfig() which caused a crash on
190 shutdown when fileConfig() was called multiple times.
191
Gerhard Häring762fbd32006-07-02 17:48:30 +0000192- The sqlite3 module did cut off data from the SQLite database at the first
193 null character before sending it to a custom converter. This has been fixed
194 now.
195
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000196Extension Modules
197-----------------
198
Tim Peters112aad32006-07-19 00:03:19 +0000199- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
200 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
201 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000202
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000203- Assigning None to pointer type fields in ctypes structures possible
204 overwrote the wrong fields, this is fixed now.
205
206- Fixed a segfault in _ctypes when ctypes.wintypes were imported
207 on non-Windows platforms.
208
209- Bug #1518190: The ctypes.c_void_p constructor now accepts any
210 integer or long, without range checking.
211
212- Patch #1517790: It is now possible to use custom objects in the ctypes
213 foreign function argtypes sequence as long as they provide a from_param
214 method, no longer is it required that the object is a ctypes type.
215
216- The '_ctypes' extension module now works when Python is configured
217 with the --without-threads option.
218
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000219- Bug #1513646: os.access on Windows now correctly determines write
220 access, again.
221
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000222- Bug #1512695: cPickle.loads could crash if it was interrupted with
223 a KeyboardInterrupt.
224
Neal Norwitza12aa882006-07-06 06:45:08 +0000225- Bug #1296433: parsing XML with a non-default encoding and
226 a CharacterDataHandler could crash the interpreter in pyexpat.
227
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000228- Patch #1516912: improve Modules support for OpenVMS.
229
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000230Build
231-----
232
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000233- Automate Windows build process for the Win64 SSL module.
234
Tim Peters32a83612006-07-10 21:08:24 +0000235- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000236 Previously, the slight difference could cause compilation errors of the
237 'zlib' module on systems with more than one version of zlib.
238
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000239- The MSI compileall step was fixed to also support a TARGETDIR
240 with spaces in it.
241
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000242- Bug #1517388: sqlite3.dll is now installed on Windows independent
243 of Tcl/Tk.
244
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000245- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000246 trying to be installed even though it's empty.

255-------------
256
Nick Coghlan2d792252006-07-06 13:47:18 +0000257- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
258 documentation for the warnings module.
259
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000260- Patch #1509163: MS Toolkit Compiler no longer available.

269Core and builtins
270-----------------
271
Georg Brandla56b9152006-06-19 06:35:54 +0000272- Patch #1507676: Error messages returned by invalid abstract object operations
273 (such as iterating over an integer) have been improved and now include the
274 type of the offending object to help with debugging.
275
Brett Cannonea3912b2006-06-13 21:46:41 +0000276- Bug #992017: A classic class that defined a __coerce__() method that returned
277 its arguments swapped would infinitely recurse and segfault the interpreter.
278
Neal Norwitz909eb122006-06-12 02:13:21 +0000279- Fix the socket tests so they can be run concurrently.
280
Neal Norwitzb9845e72006-06-12 02:11:18 +0000281- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000282 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000283
Brett Cannon22565aa2006-06-09 22:31:23 +0000284- Bug #532646: object.__call__() will continue looking for the __call__
285 attribute on objects until one without one is found. This leads to recursion
286 when you take a class and set its __call__ attribute to an instance of the
287 class. Originally fixed for classic classes, but this fix is for new-style.
288 Removes the infinite_rec_3 crasher.
289
Georg Brandl24250812006-06-09 18:45:48 +0000290- The string and unicode methods startswith() and endswith() now accept
291 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
292
Brett Cannonde3b0522006-06-08 17:00:45 +0000293- Buffer objects, at the C level, never used the char buffer
294 implementation even when the char buffer for the wrapped object was
295 explicitly requested (originally returned the read or write buffer).
296 Now a TypeError is raised if the char buffer is not present but is
297 requested.
298
Georg Brandlddbaa662006-06-04 21:56:52 +0000299- Patch #1346214: Statements like "if 0: suite" are now again optimized
300 away like they were in Python 2.4.
301
Georg Brandlb7c8f542006-05-27 12:30:25 +0000302- Builtin exceptions are now full-blown new-style classes instead of
303 instances pretending to be classes, which speeds up exception handling
304 by about 80% in comparison to 2.5a2.
305
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000306- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
307 Unicode 4.1.
308
Georg Brandlf4ef1162006-05-26 18:03:31 +0000309- Patch #921466: sys.path_importer_cache is now used to cache valid and
310 invalid file paths for the built-in import machinery which leads to
311 fewer open calls on startup.
312
Tim Peters696cf432006-05-24 21:10:40 +0000313- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
314 of-2 bases. The largest speedup is for inputs with about 1000 decimal
315 digits. Conversion from non-power-of-2 bases remains quadratic-time in
316 the number of input digits (it was and remains linear-time for bases
317 2, 4, 8, 16 and 32).
318
Tim Petersb713ec22006-05-23 18:45:30 +0000319- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
320 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
321 an integer close to ``sys.maxint``. This was repaired by patch
322 #1335972, which also gives a nice speedup.
323
Richard Jonescebbefc2006-05-23 18:28:17 +0000324- Patch #1337051: reduced size of frame objects.
325
326- PyErr_NewException now accepts a tuple of base classes as its
327 "base" parameter.
328
Richard Jones7c88dcc2006-05-23 10:37:38 +0000329- Patch #876206: function call speedup by retaining allocated frame
330 objects.
331
Georg Brandl7b90e162006-05-18 07:01:27 +0000332- Bug #1462152: file() now checks more thoroughly for invalid mode
333 strings and removes a possible "U" before passing the mode to the
334 C library function.
335
Neal Norwitz1004a532006-05-15 07:17:23 +0000336- Patch #1488312, Fix memory alignment problem on SPARC in unicode
337
Neal Norwitz373f0a72006-05-15 07:04:36 +0000338- Bug #1487966: Fix SystemError with conditional expression in assignment
339
Martin v. Löwis879768d2006-05-11 13:28:43 +0000340- WindowsError now has two error code attributes: errno, which carries
341 the error values from errno.h, and winerror, which carries the error
342 values from winerror.h. Previous versions put the winerror.h values
343 (from GetLastError()) into the errno attribute.
344
Martin v. Löwis77736712006-05-04 05:51:03 +0000345- Patch #1475845: Raise IndentationError for unexpected indent.
346
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000347- Patch #1479181: split open() and file() from being aliases for each other.
348
Tim Peters44bd9862006-06-01 13:49:23 +0000349- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
350 methods were always silently ignored by dictionaries when comparing keys.
351 They are now passed through (except when using the C API function
352 ``PyDict_GetItem()``, whose semantics did not change).
353
354- Bug #1456209: In some obscure cases it was possible for a class with a
355 custom ``__eq__()`` method to confuse dict internals when class instances
356 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
357 No, you don't have any code that did this ;-)

360-----------------
361
Trent Mick960a3f82006-06-28 20:30:41 +0000362- Bug #1295808: expat symbols should be namespaced in pyexpat
363
364- Patch #1462338: Upgrade pyexpat to expat 2.0.0
365
Brett Cannon6ee7d012006-06-08 16:23:04 +0000366- Change binascii.hexlify to accept a read-only buffer instead of only a char
367 buffer and actually follow its documentation.
368
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000369- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
370
Nick Coghlanc649ec52006-05-29 12:43:05 +0000371- Patch #1478788 (modified version): The functional extension module has
372 been renamed to _functools and a functools Python wrapper module added.
373 This provides a home for additional function related utilities that are
374 not specifically about functional programming. See PEP 309.
375
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000376- Patch #1493701: performance enhancements for struct module.
377
Georg Brandl378d5922006-05-17 14:26:50 +0000378- Patch #1490224: time.altzone is now set correctly on Cygwin.
379
Georg Brandl8d3342b2006-05-16 07:38:27 +0000380- Patch #1435422: zlib's compress and decompress objects now have a
381 copy() method.
382
Andrew MacIntyre92913322006-06-13 15:04:24 +0000383- Patch #1454481: thread stack size is now tunable at runtime for thread
384 enabled builds on Windows and systems with Posix threads support.
385
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000386- On Win32, os.listdir now supports arbitrarily-long Unicode path names
387 (up to the system limit of 32K characters).
388
389- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
390 As a result, these functions now raise WindowsError instead of OSError.
391
Tim Peters7a822da2006-05-25 21:50:17 +0000392- ``time.clock()`` on Win64 should use the high-performance Windows
393 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
394 Windows platforms).
395
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000396- Calling Tk_Init twice is refused if the first call failed as that
397 may deadlock.
398
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000399- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
400 accept it without potentially using an uninitialized pointer.
401
402- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
403 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
404 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000405
Gregory P. Smith372b5832006-06-05 18:48:21 +0000406- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000407 [pybsddb project SF patch number 1466734]
408
Gregory P. Smith372b5832006-06-05 18:48:21 +0000409- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
410 parameter is supplied. [SF pybsddb bug #1477863]
411
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000412- bsddb: the __len__ method of a DB object has been fixed to return correct
413 results. It could previously incorrectly return 0 in some cases.
414 Fixes SF bug 1493322 (pybsddb bug 1184012).
415
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000416- bsddb: the bsddb.dbtables Modify method now raises the proper error and
417 aborts the db transaction safely when a modifier callback fails.
418 Fixes SF python patch/bug #1408584.
419
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000420- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000421 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000422 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
423 database calls that would previously deadlock. [SF python bug #775414]
424
Vinay Sajip28e57612006-07-01 10:45:20 +0000425- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000426
Walter Dörwald4994d952006-06-19 08:07:50 +0000427- Patch #1506645: add Python wrappers for the curses functions
428 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000429

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000433- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
434 functions.
435
Martin v. Löwis3798da02006-06-17 18:44:27 +0000436- Patch #812986: Update turtle output even if not tracing.
437
Vinay Sajip28e57612006-07-01 10:45:20 +0000438- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000439 Tkinter.BaseWidget.
440
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000441- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
442
Martin v. Löwis337487e2006-06-17 09:15:14 +0000443- Patch #763580: Add name and value arguments to Tkinter variable
444 classes.
445
Georg Brandl83cc0d02006-06-14 08:50:03 +0000446- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
447 mime.types file for determining MIME types.
448
Georg Brandl2605ca82006-06-14 06:08:31 +0000449- Bug #1339007: Shelf objects now don't raise an exception in their
450 __del__ method when initialization failed.
451
Martin v. Löwisd8251432006-06-14 05:21:04 +0000452- Patch #1455898: The MBCS codec now supports the incremental mode for
453 double-byte encodings.
454
Tim Peters43898b42006-06-14 04:09:25 +0000455- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
456 guarantee that adjacent triples in the return list always describe
457 non-adjacent blocks. Previously, a pair of matching blocks could end
458 up being described by multiple adjacent triples that formed a partition
459 of the matching pair.
460
Greg Ward0e0c9f42006-06-11 16:24:11 +0000461- Bug #1498146: fix optparse to handle Unicode strings in option help,
462 description, and epilog.
463
Greg Wardd1c797e2006-06-11 14:42:41 +0000464- Bug #1366250: minor optparse documentation error.
465
Greg Ward7f547402006-06-11 00:40:49 +0000466- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
467 clarify docs.
468
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000469- The wsgiref package has been added to the standard library.
470
Nick Coghlan676725d2006-06-08 13:54:49 +0000471- The functions update_wrapper() and wraps() have been added to the functools
472 module. These make it easier to copy relevant metadata from the original
473 function when writing wrapper functions.
474
Tim Petersd6a9eef2006-06-05 01:48:21 +0000475- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
476 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000477
Martin v. Löwis3f767792006-06-04 19:36:28 +0000478- Patch #1359618: Speed up charmap encoder by using a trie structure
479 for lookup.
480
Tim Petersd609b1a2006-06-02 23:22:51 +0000481- The functions in the ``pprint`` module now sort dictionaries by key
482 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
483 if and only if its display required more than one line, although that
484 wasn't documented. The new behavior increases predictability; e.g.,
485 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
486
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000487- Patch #1497027: try HTTP digest auth before basic auth in urllib2
488 (thanks for J. J. Lee).
489
Georg Brandl2b330372006-05-28 20:23:12 +0000490- Patch #1496206: improve urllib2 handling of passwords with respect to
491 default HTTP and HTTPS ports.
492
George Yoshidaf3c65de2006-05-28 16:39:09 +0000493- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
494
Bob Ippolito7298f272006-05-23 18:43:47 +0000495- Patch #1281707: speed up gzip.readline.
496
Georg Brandlb89316f2006-05-17 15:51:16 +0000497- Patch #1180296: Two new functions were added to the locale module:
498 format_string() to get the effect of "format % items" but locale-aware,
499 and currency() to format a monetary number with currency sign.
500
Georg Brandle3a25832006-05-17 14:56:04 +0000501- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
502 and several features added, such as speed and geometry control.
503
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000504- Patch #1488881: add support for external file objects in bz2 compressed
505 tarfiles.
506
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000507- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
508 stdout arguments, making it possible to redirect input and output
509 for remote debugging.
510
511- Patch #1484695: Update the tarfile module to version 0.8. This fixes
512 a couple of issues, notably handling of long file names using the
513 GNU LONGNAME extension.
514
515- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
516 new flag when ``name`` is already the name of an option flag.
517
518- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
519 package.
520
521- Patch #1472854: make the rlcompleter.Completer class usable on non-
522 UNIX platforms.
523
524- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
525
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000526- Bug #1472827: correctly escape newlines and tabs in attribute values in
527 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000557What's New in Python 2.5 alpha 2?
558=================================
559
560*Release date: 27-APR-2006*
561
562Core and builtins
563-----------------
564
Thomas Heller1b046642006-04-18 18:51:06 +0000565- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
566 by converting these apis from macros into exported functions again:
567
568 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
569 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
570 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
571 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
572 PyRun_String Py_CompileString
573
Martin v. Löwis45294a92006-04-18 06:24:08 +0000574- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
575
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000576- All uses of PyStructSequence_InitType have been changed to initialize
577 the type objects only once, even if the interpreter is initialized
578 multiple times.
579
Neal Norwitz61546162006-04-14 05:20:28 +0000580- Bug #1454485, array.array('u') could crash the interpreter. This was
581 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
582 to unicode when it didn't make sense. 'u#' now requires a unicode string.
583
584- Py_UNICODE is unsigned. It was always documented as unsigned, but
585 due to a bug had a signed value in previous versions.
586
Tim Peters3a5e8b12006-04-11 01:44:07 +0000587- Patch #837242: ``id()`` of any Python object always gives a positive
588 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
589 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000590 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000591 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000592
Tim Peters3a5e8b12006-04-11 01:44:07 +0000593 def __hash__(self):
594 return id(self) # WRONG
595
596 because a hash result must be a (short) Python int but it was always
597 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000598 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000599 was always usable as a hash value before this patch. That's no longer
600 necessarily so.
601
602- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000603 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000604 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000605 #1454844)
606
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000607- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
608 involving generators that have paused outside of any ``try`` or ``with``
609 blocks. (In 2.5a1, a paused generator that was part of a reference
610 cycle could not be garbage collected, regardless of whether it was
611 paused in a ``try`` or ``with`` block.)

614-----------------
615
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000616- Patch #1191065: Fix preprocessor problems on systems where recvfrom
617 is a macro.
618
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000619- Bug #1467952: os.listdir() now correctly raises an error if readdir()
620 fails with an error condition.
621
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000622- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
623
624- Bug #1117761: bsddb.*open() no longer raises an exception when using
625 the cachesize parameter.
626
627- Bug #1149413: bsddb.*open() no longer raises an exception when using
628 a temporary db (file=None) with the 'n' flag to truncate on open.
629
630- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
631 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000632
Armin Rigoa9017c32006-04-19 11:50:27 +0000633- Patch #1062014: AF_UNIX sockets under Linux have a special

637-------
638
Peter Astrand7d1d4362006-07-14 14:04:45 +0000639- Bug #1223937: subprocess.CalledProcessError reports the exit status
640 of the process using the returncode attribute, instead of
641 abusing errno.
642
Tim Peters711bf302006-04-25 03:31:36 +0000643- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
644 a doctest to be skipped (the code is not run, and the expected output
645 or exception is ignored).
646
Nick Coghlanda2268f2006-04-24 04:37:15 +0000647- Fixed contextlib.nested to cope with exceptions being raised and
648 caught inside exit handlers.
649
Greg Wardab05edc2006-04-23 03:47:58 +0000650- Updated optparse module to Optik 1.5.1 (allow numeric constants in
651 hex, octal, or binary; add ``append_const`` action; keep going if
652 gettext cannot be imported; added ``OptionParser.destroy()`` method;
653 added ``epilog`` for better help generation).
654
Tim Peters21fbd572006-04-21 21:18:10 +0000655- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
656 called from a thread spawned as a side effect of importing a module.
657
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000658- The pydoc module now supports documenting packages contained in
659 .zip or .egg files.
660
661- The pkgutil module now has several new utility functions, such
662 as ``walk_packages()`` to support working with packages that are either
663 in the filesystem or zip files.
664
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000665- The mailbox module can now modify and delete messages from
666 mailboxes, in addition to simply reading them. Thanks to Gregory
667 K. Johnson for writing the code, and to the 2005 Google Summer of
668 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000669
Tim Petersc7605f22006-04-17 21:12:33 +0000670- The ``__del__`` method of class ``local`` in module ``_threading_local``
671 returned before accomplishing any of its intended cleanup.
672

Anthony Baxtere29002c2006-04-12 12:07:31 +0000679- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
680 Windows. Bug #1469163.
681
Phillip J. Eby47032112006-04-11 01:07:43 +0000682- The warnings, linecache, inspect, traceback, site, and doctest modules
683 were updated to work correctly with modules imported from zipfiles or
684 via other PEP 302 __loader__ objects.
685
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000686- Patch #1467770: Reduce usage of subprocess._active to processes which
687 the application hasn't waited on.
688
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000689- Patch #1462222: Fix Tix.Grid.

694 direct output to an alternate file-like object.
695
Anthony Baxter51bcb682006-04-05 14:51:42 +0000696Build
697-----
698
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000699- The Makefile now has a reindent target, which runs reindent.py on
700 the library.
701
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000702- Patch #1470875: Building Python with MS Free Compiler
703
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000704- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000705
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000706- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
707 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000708 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000709 CXX from --with-cxx-main, see description in README.
710
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000711- Patch #1429775: Link extension modules with the shared libpython.
712
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000713- Fixed a libffi build problem on MIPS systems.
714
Tim Peters8931ff12006-05-13 23:28:20 +0000715- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
716 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
717 and "%zu" for unsigned integers of type ``size_t``.
718
Anthony Baxter51bcb682006-04-05 14:51:42 +0000719Tests
720-----
721
Nick Coghlanda2268f2006-04-24 04:37:15 +0000722- test_contextlib now checks contextlib.nested can cope with exceptions
723 being raised and caught inside exit handlers.
724
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000725- test_cmd_line now checks operation of the -m and -c command switches
726
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000727- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
728 it separately and by hand. It also wasn't cleaning up its changes to
729 the current Decimal context.
730
Thomas Woutersabd08882006-04-26 15:53:30 +0000731- regrtest.py now has a -M option to run tests that test the new limits of
732 containers, on 64-bit architectures. Running these tests is only sensible
733 on 64-bit machines with more than two gigabytes of memory. The argument
734 passed is the maximum amount of memory for the tests to use.

743-------------
744
Tim Petersb06d28c2006-05-12 01:57:59 +0000745- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
746
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000747- PEP 343: Added Context Types section to the library reference
748 and attempted to bring other PEP 343 related documentation into
749 line with the implementation and/or python-dev discussions.
750
Tim Peters8dc73d22006-04-24 02:03:16 +0000751- Bug #1337990: clarified that ``doctest`` does not support examples
752 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000755What's New in Python 2.5 alpha 1?
756=================================
757
Anthony Baxterebed3f62006-04-03 15:03:44 +0000758*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000759
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000760Core and builtins
761-----------------
762
Nick Coghlan43832302006-04-23 17:04:07 +0000763- PEP 338: -m command line switch now delegates to runpy.run_module
764 allowing it to support modules in packages and zipfiles
765
Martin v. Löwisc661b882006-04-20 04:54:23 +0000766- On Windows, .DLL is not an accepted file name extension for
767 extension modules anymore; extensions are only found if they
768 end in .PYD.
769
Martin v. Löwisea62d252006-04-03 10:56:49 +0000770- Bug #1421664: sys.stderr.encoding is now set to the same value as
771 sys.stdout.encoding.
772
Neal Norwitz92e212f2006-04-03 04:48:37 +0000773- __import__ accepts keyword arguments.
774
Georg Brandlccadf842006-03-31 18:54:53 +0000775- Patch #1460496: round() now accepts keyword arguments.
776
Anthony Baxter262c00a2006-03-30 10:53:17 +0000777- Fixed bug #1459029 - unicode reprs were double-escaped.
778
Hye-Shik Changd478f342006-03-23 12:32:36 +0000779- Patch #1396919: The system scope threads are reenabled on FreeBSD
780 5.4 and later versions.
781
Neal Norwitze98ccf62006-03-23 05:39:47 +0000782- Bug #1115379: Compiling a Unicode string with an encoding declaration
783 now gives a SyntaxError.
784
Georg Brandlabd1ff82006-03-18 07:59:59 +0000785- Previously, Python code had no easy way to access the contents of a
786 cell object. Now, a ``cell_contents`` attribute has been added
787 (closes patch #1170323).
788
Tim Peterscf79aac2006-03-16 01:14:46 +0000789- Patch #1123430: Python's small-object allocator now returns an arena to
790 the system ``free()`` when all memory within an arena becomes unused
791 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
792 freed. Some applications will see a drop in virtual memory size now,
793 especially long-running applications that, from time to time, temporarily
794 use a large number of small objects. Note that when Python returns an
795 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000796 platform C library will in turn return that memory to the operating system.
797 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000798 appears to be effective at least on Microsoft C and gcc-based systems.
799 Thanks to Evan Jones for hard work and patience.
800
Georg Brandl533ff6f2006-03-08 18:09:27 +0000801- Patch #1434038: property() now uses the getter's docstring if there is
802 no "doc" argument given. This makes it possible to legitimately use
803 property() as a decorator to produce a read-only property.
804
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000805- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
806 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
807 of requiring an int or long in slicing and a few other contexts, enabling
808 other objects (e.g. Numeric Python's integers) to be used as slice indices.
809
Neal Norwitz995acdf2006-03-07 05:01:00 +0000810- Fixed various bugs reported by Coverity's Prevent tool.
811
Brett Cannonbf364092006-03-01 04:25:17 +0000812- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
813 new exception base class, BaseException, which has a new message attribute.
814 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
815 Raising a string exception now raises a DeprecationWarning.
816
Thomas Woutersfb609f42006-02-28 16:37:25 +0000817- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
818 explicitly relative, using 'from .module import name' to mean 'from the same
819 package as this module is in. Imports without dots still default to the
820 old relative-then-absolute, unless 'from __future__ import
821 absolute_import' is used.
822
Brett Cannona7446e32006-02-27 23:39:10 +0000823- Properly check if 'warnings' raises an exception (usually when a filter set
824 to "error" is triggered) when raising a warning for raising string
825 exceptions.
826
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000827- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000828 The name was removed from Include/code.h.
829
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000830- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000831
Guido van Rossum1968ad32006-02-25 22:38:04 +0000832- Patch 1433928:
833 - The copy module now "copies" function objects (as atomic objects).
834 - dict.__getitem__ now looks for a __missing__ hook before raising
835 KeyError.
836
Tim Peters84ef21c2006-02-28 20:39:06 +0000837- PEP 343: with statement implemented. Needs ``from __future__ import
838 with_statement``. Use of 'with' as a variable will generate a warning.
839 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000840 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000841 The following objects have __context__ methods:
842 - The built-in file type.
843 - The thread.LockType type.
844 - The following types defined by the threading module:
845 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
846 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000847
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000848- Fix the encodings package codec search function to only search
849 inside its own package. Fixes problem reported in patch #1433198.
850
851 Note: Codec packages should implement and register their own
852 codec search function. PEP 100 has the details.
853
Tim Peters9ea89d22006-06-04 03:26:02 +0000854- PEP 353: Using ``Py_ssize_t`` as the index type.
855
856- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
857 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
858 now allow Python to make use of memory blocks exceeding 2**32 bytes for
859 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
860 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000861
Neal Norwitzfc76d632006-01-10 06:03:13 +0000862- Patch #1400181, fix unicode string formatting to not use the locale.
863 This is how string objects work. u'%f' could use , instead of .
864 for the decimal point. Now both strings and unicode always use periods.
865
Neal Norwitz671b9e32006-01-09 07:07:12 +0000866- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
867 configure would break checking curses.h.
868
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000869- Bug #959576: The pwd module is now builtin. This allows Python to be
870 built on UNIX platforms without $HOME set.
871
Neal Norwitzc10978f2005-12-19 06:07:16 +0000872- Bug #1072182, fix some potential problems if characters are signed.
873
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000874- Bug #889500, fix line number on SyntaxWarning for global declarations.
875
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000876- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
877
Neal Norwitze7214a12005-12-18 05:03:17 +0000878- Support for converting hex strings to floats no longer works.
879 This was not portable. float('0x3') now raises a ValueError.
880
Barry Warsaw2a38a862005-12-18 01:27:35 +0000881- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000882 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000883 is now displayed in interactive prompt banner.
884
Georg Brandlfa166682005-12-17 21:45:17 +0000885- Implementation of PEP 341 - Unification of try/except and try/finally.
886 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000887 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000888
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000889- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
890 now encodes backslash correctly.
891
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000892- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
893
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000894- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000895 and long longs.
896
Neal Norwitz67715f02005-11-09 06:59:35 +0000897- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000898 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000899 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000900
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000901- Replaced most Unicode charmap codecs with new ones using the
902 new Unicode translate string feature in the builtin charmap
903 codec; the codecs were created from the mapping tables available
904 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
905 encodings now include a mapping for the Apple logo)
906
Tim Peterse3547fd2005-12-16 23:13:57 +0000907- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000908
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000909- Sped up some Unicode operations.

Martin v. Löwisbd260da2006-02-26 19:42:26 +0000911- A new AST parser implementation was completed. The abstract
912 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000913 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000914
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000915- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000916 The following code now raises a SyntaxError: foo(a = i for i in range(10))
917
Neal Norwitz708e51a2005-10-03 04:48:15 +0000918- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
919
Neal Norwitz11bd1192005-10-03 00:54:56 +0000920- SF Bug #887946: fix segfault when redirecting stdin from a directory.
921 Provide a warning when a directory is passed on the command line.
922
Neal Norwitz40d37812005-10-02 01:48:49 +0000923- Fix segfault with invalid coding.
924
925- SF bug #772896: unknown encoding results in MemoryError.
926
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000927- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000928 supported a __len__() method which evaluated to False when the iterator
929 was empty.
930
Guido van Rossum630db602005-09-20 18:49:54 +0000931- On 64-bit platforms, when __len__() returns a value that cannot be
932 represented as a C int, raise OverflowError.
933
Skip Montanarof8948ca2005-09-19 03:54:46 +0000934- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000935 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000936
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000937- SF bug #893549: parsing keyword arguments was broken with a few format
938 codes.
939
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000940- Changes donated by Elemental Security to make it work on AIX 5.3
941 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
942 bug #105470: test_pwd fails on 64bit system (Opteron).
943
Guido van Rossum539c6622005-09-14 17:49:54 +0000944- Changes donated by Elemental Security to make it work on HP-UX 11 on
945 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
946
Georg Brandl4550b8d2005-08-26 06:43:52 +0000947- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000948 (fixes bug #1119418).
949
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000950- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
951
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000952- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
953 exceptions that cause a function to exit.
954
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000955- The implementation of set() and frozenset() was revised to use its
956 own internal data structure. Memory consumption is reduced by 1/3
957 and there are modest speed-ups as well. The API is unchanged.
958
Tim Petersde7990b2005-07-17 23:45:23 +0000959- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
960
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000961- SF bug #1229429: PyObject_CallMethod failed to decrement some
962 reference counts in some error exit cases.
963
Tim Petersecc6e6a2005-07-10 22:30:55 +0000964- SF bug #1185883: Python's small-object memory allocator took over
965 a block managed by the platform C library whenever a realloc specified
966 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000967 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000968 portable way to copy data from the C-managed block into Python's
969 small-object space without risking a memory fault. Python's small-object
970 realloc now leaves such blocks under the control of the platform C
971 realloc.
972
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000973- SF bug #1232517: An overflow error was not detected properly when
974 attempting to convert a large float to an int in os.utime().
975
Raymond Hettinger3296e692005-06-29 23:29:56 +0000976- SF bug #1224347: hex longs now print with lowercase letters just
977 like their int counterparts.
978
Michael W. Hudson188d4362005-06-20 16:52:57 +0000979- SF bug #1163563: the original fix for bug #1010677 ("thread Module
980 Breaks PyGILState_Ensure()") broke badly in the case of multiple
981 interpreter states; back out that fix and do a better job (see
982 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
983 for a longer write-up of the problem).
984
Michael W. Hudsondf888462005-06-03 14:41:55 +0000985- SF patch #1180995: marshal now uses a binary format by default when
986 serializing floats.
987
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000988- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
989 the routines that promise to produce IEEE 754 binary representations
990 of floats now simply copy bytes around.
991
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000992- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
993 278.
994
Brett Cannonc3647ac2005-04-26 03:45:26 +0000995- patch #1109424: int, long, float, complex, and unicode now check for the
996 proper magic slot for type conversions when subclassed. Previously the
997 magic slot was ignored during conversion. Semantics now match the way
998 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000999 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001000 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001001 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001002
Barry Warsawc8d907c2005-04-19 23:43:40 +00001003- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1004 NULL, now raise an AttributeError when attempting to set or delete the
1005 attribute. Previously a TypeError was raised, but this was inconsistent
1006 with the equivalent pure-Python implementation.
1007
Michael W. Hudson774479c2005-04-18 08:46:17 +00001008- It is now safe to call PyGILState_Release() before
1009 PyEval_InitThreads() (note that if there is reason to believe there
1010 are multiple threads around you still must call PyEval_InitThreads()
1011 before using the Python API; this fix is for extension modules that
1012 have no way of knowing if Python is multi-threaded yet).
1013
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001014- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1015 disabled caused a crash.
1016
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001017- Bug #1165306: instancemethod_new allowed the creation of a method
1018 with im_class == im_self == NULL, which caused a crash when called.
1019
Tim Petersecc6e6a2005-07-10 22:30:55 +00001020- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001021 fixes the crash seen in bug #1165761
1022
Raymond Hettinger96229b12005-03-11 06:49:40 +00001023- Added two new builtins, any() and all().
1024
Brett Cannon409d8f22005-03-05 06:47:57 +00001025- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001026 (e.g., ``class C(): pass`` is no longer a syntax error).
1027 Patch #1176012 added support to the 'parser' module and 'compiler' package
1028 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001029
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001030- Patch #1115086: Support PY_LONGLONG in structmember.
1031
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001032- Bug #1155938: new style classes did not check that __init__() was
1033 returning None.
1034
Tim Petersecc6e6a2005-07-10 22:30:55 +00001035- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001036 ('\') with a specific error message.
1037
Martin v. Löwisff232d72005-03-03 09:24:38 +00001038- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1039
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001040- Bug #1124295: the __name__ attribute of file objects was
1041 inadvertently made inaccessible in restricted mode.
1042
Tim Petersecc6e6a2005-07-10 22:30:55 +00001043- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001044 an ferror() call.
1045
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001046- min() and max() now support key= arguments with the same meaning as in
1047 list.sort().
1048
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001049- The peephole optimizer now performs simple constant folding in expressions:
1050 (2+3) --> (5).
1051
Raymond Hettingera422c342005-01-11 03:03:27 +00001052- set and frozenset objects can now be marshalled. SF #1098985.
1053
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001054- Bug #1077106: Poor argument checking could cause memory corruption
1055 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001056
Jeremy Hyltonab630502005-02-04 18:44:06 +00001057- The parser did not complain about future statements in illegal
1058 positions. It once again reports a syntax error if a future
1059 statement occurs after anything other than a doc string.
1060
Neil Schemenauercf52c072005-08-12 17:34:58 +00001061- Change the %s format specifier for str objects so that it returns a
1062 unicode instance if the argument is not an instance of basestring and
1063 calling __str__ on the argument returns a unicode instance.
1064
Tim Petersf4e69282006-02-27 17:15:31 +00001065- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1066 current thread state when the auto-GIL-state machinery knows about
1067 it (since the thread state is being deleted, continuing to remember it
1068 can't help, but can hurt if another thread happens to get created with
1069 the same thread id).
1070
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001071Extension Modules
1072-----------------
1073

Neal Norwitz10be10c2006-03-16 06:50:13 +00001087 util, whatsound, whrandom, zmod
1088
1089- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1090
1091- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001092 is deprecated. The undocumented re.engine variable no longer exists.
1093
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001094- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1095 SS2 (single-shift 2) escape sequences correctly.
1096
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001097- The unicodedata module was updated to the 4.1 version of the Unicode
1098 database. The 3.2 version is still available as unicodedata.db_3_2_0
1099 for applications that require this specific version (such as IDNA).
1100
Neal Norwitzb62c4332006-03-04 18:35:47 +00001101- The timing module is no longer built by default. It was deprecated
1102 in PEP 4 in Python 2.0 or earlier.
1103
Guido van Rossum1968ad32006-02-25 22:38:04 +00001104- Patch 1433928: Added a new type, defaultdict, to the collections module.
1105 This uses the new __missing__ hook behavior added to dict (see above).
1106
Georg Brandldbd83392006-02-20 09:42:33 +00001107- Bug #854823: socketmodule now builds on Sun platforms even when
1108 INET_ADDRSTRLEN is not defined.
1109
Georg Brandlf4f44152006-02-18 22:29:33 +00001110- Patch #1393157: os.startfile() now has an optional argument to specify
1111 a "command verb" to invoke on the file.
1112
Neal Norwitz082b2df2006-02-07 07:04:46 +00001113- Bug #876637, prevent stack corruption when socket descriptor
1114 is larger than FD_SETSIZE.
1115
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001116- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1117 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1118 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1119
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001120- Patch #1422385: The nis module now supports access to domains other
1121 than the system default domain.
1122
Martin v. Löwis14694662006-02-03 12:54:16 +00001123- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1124 are reported, the limit on path name lengths is removed, and stat reports
1125 WindowsError now (instead of OSError).
1126
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001127- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

1202 the request code argument, which results in more C-like behaviour
1203 for large or negative values.
1204
Tim Petersecc6e6a2005-07-10 22:30:55 +00001205- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

1220
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00001221- operator.itemgetter() and operator.attrgetter() now support retrieving

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001261- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1262 been renamed to have only a single underscore prefix. This was done to
1263 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001264
Nick Coghlan43832302006-04-23 17:04:07 +00001265- PEP 338: new module runpy defines a run_module function to support
1266 executing modules which provide access to source code or a code object
1267 via the PEP 302 import mechanisms.
1268
Anthony Baxter93f5b932006-04-03 08:05:07 +00001269- The email module's parsedate_tz function now sets the daylight savings

1277 in attribute values.
1278
Anthony Baxterc51ee692006-04-01 00:57:31 +00001279- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001280 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001281 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001282 module will not be built.
1283
Tim Petersc17976e2006-04-01 00:26:53 +00001284- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1285 aren't officially supported here, and trying to use them will probably
1286 raise an exception some day. But dicts have been allowed, and "mostly
1287 worked", so support for them won't go away without warning.
1288
Georg Brandl338ef7d2006-03-31 18:42:16 +00001289- Bug #1445068: getpass.getpass() can now be given an explicit stream
1290 argument to specify where to write the prompt.
1291

1301 to make it easier to monitor when daemon threads have completed
1302 processing all enqueued tasks. Patch #1455676.
1303

1307
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001308- email 4.0 package now integrated. This is largely the same as the email 3.0
1309 package that was included in Python 2.3, except that PEP 8 module names are
1310 now used (e.g. mail.message instead of email.Message). The MIME classes
1311 have been moved to a subpackage (e.g. email.mime.text instead of
1312 email.MIMEText). The old names are still supported for now. Several
1313 deprecated Message methods have been removed and lots of bugs have been
1314 fixed. More details can be found in the email package documentation.
1315
Walter Dörwald40108c92006-03-27 08:15:44 +00001316- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1317 (a subclass of tuple) that provides incremental decoders and encoders
1318 (a way to use stateful codecs without the stream API). Python functions
1319 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1320 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1321 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001322
Walter Dörwald067db482006-03-15 22:17:27 +00001323- Patch #1359365: Calling next() on a closed StringIO.String object raises
1324 a ValueError instead of a StopIteration now (like file and cString.String do).
1325 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1326 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001327
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001328- A regrtest option -w was added to re-run failed tests in verbose mode.

Tim Peterse3547fd2005-12-16 23:13:57 +00001400 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1401 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1402 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1403 Ronald L. Rivest offered this advice for Python:
1404
1405 "The consensus of researchers in this area (at least as
1406 expressed at the NIST Hash Function Workshop 10/31/05),
1407 is that SHA-256 is a good choice for the time being, but
1408 that research should continue, and other alternatives may
1409 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001410
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001411- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandlb9256022005-08-24 18:46:39 +00001457- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
1458 ContentTooShortException, when the actually downloaded size does not
1459 match the Content-Length header.
1460
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +00001461- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.
1462
Martin v. Löwis56066d22005-08-24 07:38:12 +00001463- Bug #1178484: Return complete lines from codec stream readers
1464 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001465 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001466

1472 to ntpath, macpath, os2emxpath and riscospath.
1473
Guido van Rossum755149f2005-07-27 00:00:44 +00001474- Fix a problem in Tkinter introduced by SF patch #869468: delete bogus
1475 __hasattr__ and __delattr__ methods on class Tk that were breaking
1476 Tkdnd.
1477
Georg Brandl5dbda752005-07-17 20:27:41 +00001478- Bug #1015140: disambiguated the term "article id" in nntplib docs and
1479 docstrings to either "article number" or "message id".
1480
Georg Brandla4a8b822005-07-15 09:13:21 +00001481- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
1482 parameter, but uses the usual "kwargs=None".
1483
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001484- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00001485 Patch #1209527 (Contributed by Connelly).
1486
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00001487- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
1488 to W3C name (404 -> 'Not Found'). RFE #1216944.
1489
Georg Brandl9e43acf2005-07-04 17:16:07 +00001490- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1491 as this can cause problems with apps closing all file descriptors.
1492
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001493- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001494 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00001495

1497
Georg Brandlfbff1bc2005-06-26 21:36:25 +00001498- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
1499 error messages.
1500
Georg Brandl379f99d2005-06-26 21:09:38 +00001501- Bug #1108948: Cookie.py produced invalid JavaScript code.
1502
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001503- The tokenize module now detects and reports indentation errors.
1504 Bug #1224621.
1505
Raymond Hettinger68c04532005-06-10 11:05:19 +00001506- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001507 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001508 the generate_tokens() function now accepts a callable argument that
1509 terminates by raising StopIteration.
1510
Georg Brandl9166e1a2005-06-04 09:20:03 +00001511- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1512
Georg Brandl268e61c2005-06-03 14:28:50 +00001513- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1514 component of the path.
1515
Skip Montanaro174dd222005-05-14 20:54:16 +00001516- Patch #1120353: The xmlrpclib module provides better, more transparent,
1517 support for datetime.{datetime,date,time} objects. With use_datetime set
1518 to True, applications shouldn't have to fiddle with the DateTime wrapper
1519 class at all.
1520
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001521- distutils.commands.upload was added to support uploading distribution
1522 files to PyPI.
1523
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001524- distutils.commands.register now encodes the data as UTF-8 before posting
1525 them to PyPI.
1526
Raymond Hettinger267b8682005-03-27 10:47:39 +00001527- decimal operator and comparison methods now return NotImplemented
1528 instead of raising a TypeError when interacting with other types. This
1529 allows other classes to implement __radd__ style methods and have them
1530 work as expected.
1531
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001532- Bug #1163325: Decimal infinities failed to hash. Attempting to
1533 hash a NaN raised an InvalidOperation instead of a TypeError.
1534
Tim Petersecc6e6a2005-07-10 22:30:55 +00001535- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001536 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1537

1567
Raymond Hettingerbab41432005-02-05 01:31:19 +00001568- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1569
Guido van Rossumd0641422005-02-03 15:01:24 +00001570- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1571 disables recursive traversal through instance attributes, which can
1572 be exploited in various ways.
1573
Tim Peterse3547fd2005-12-16 23:13:57 +00001574- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001575 flags on the HTTP listening socket.
1576
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001577- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1578 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1579
Tim Peterse3547fd2005-12-16 23:13:57 +00001580- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001581 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1582
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001583- Bug #1110478: Revert os.environ.update to do putenv again.
1584
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001585- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1586
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001587- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1588
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001589- Enhancements to the csv module:
1590
1591 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001592 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001593 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001594 + Dialect parameter parsing has been re-implemented to improve error
1595 reporting.
1596 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1597 dictates.
1598 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001599 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001600 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001601 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1602 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001603 + reader now allows \r characters to be quoted (previously it only allowed
1604 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001605 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001606 + Dialect classes passed to the module are no longer instantiated by
1607 the module before being parsed (the former validation scheme required
1608 this, but the mechanism was unreliable).
1609 + The dialect registry now contains instances of the internal
1610 C-coded dialect type, rather than references to python objects.
1611 + the internal c-coded dialect type is now immutable.
1612 + register_dialect now accepts the same keyword dialect specifications
1613 as the reader and writer, allowing the user to register dialects
1614 without first creating a dialect class.
1615 + a configurable limit to the size of parsed fields has been added -
1616 previously, an unmatched quote character could result in the entire
1617 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001618 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001619 the parser field size limit (returning the former limit). The initial
1620 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001621 + A line_num attribute has been added to the reader object, which tracks
1622 the number of lines read from the source iterator. This is not
1623 the same as the number of records returned, as records can span
1624 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001625 + reader and writer objects were not being registered with the cyclic-GC.
1626 This has been fixed.
1627
Brett Cannone6539c42005-01-08 02:43:53 +00001628- _DummyThread objects in the threading module now delete self.__block that is
1629 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1630 lock primitives tend to be limited in number and thus should not be wasted on
1631 a _DummyThread object. Fixes bug #1089632.
1632
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001633- The imghdr module now detects Exif files.
1634
Raymond Hettinger6065d322004-12-20 23:51:53 +00001635- StringIO.truncate() now correctly adjusts the size attribute.
1636 (Bug #951915).
1637
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001638- locale.py now uses an updated locale alias table (built using
1639 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1640 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001641 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001642
Raymond Hettinger3557f422004-12-07 12:02:02 +00001643- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1644
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001645- the pickle module no longer accepts the deprecated None option in the
1646 args tuple returned by __reduce__().
1647
Brett Cannon84667c02004-12-07 03:25:18 +00001648- optparse now optionally imports gettext. This allows its use in setup.py.
1649
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001650- the pickle module no longer uses the deprecated bin parameter.
1651
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001652- the shelve module no longer uses the deprecated binary parameter.
1653
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001654- the pstats module no longer uses the deprecated ignore() method.
1655
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001656- the filecmp module no longer uses the deprecated use_statcache argument.
1657
Raymond Hettinger664347b2004-12-04 21:21:53 +00001658- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1659 extended or overridden by subclasses. Formerly, the subclassed method would
1660 be ignored by the rest of the module. (Bug #1078905).
1661
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001662- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001663 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001664
Walter Dörwald36733692004-12-22 12:50:50 +00001665- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1666 once when a size argument is given. This prevents a buffer overflow in the
1667 tokenizer with very long source lines.
1668
Barry Warsaw538561e2006-01-01 21:48:54 +00001669- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1670 immediately after creating the object, without any intervening
1671 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001672
Skip Montanaro05885812005-01-16 20:48:27 +00001673- The reconvert.quote function can now emit triple-quoted strings. The
1674 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001675
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001676- ``UserString.MutableString`` now supports negative indices in
1677 ``__setitem__`` and ``__delitem__``
1678
Greg Ward40407942005-03-05 02:53:17 +00001679- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1680 correctly.
1681
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001682- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1683 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1684 character even if the user has passed a size parameter to get a proper
1685 line ending. Remove the special handling of a "\r\n" that has been split
1686 between two lines.
1687
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001688- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1689 about illegal code points. The codec now supports PEP 293 style error
1690 handlers.
1691
Walter Dörwald78a78b02005-09-01 12:04:29 +00001692- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001693 from the input stream, so that the output is a byte string in the correct
1694 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001695
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001696- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1697 considering it exactly like a '*'.
1698
Walter Dörwald007f8df2005-10-09 19:42:27 +00001699- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1700 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001701
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001702- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1703
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001704- Patch #1413711: Certain patterns of differences were making difflib
1705 touch the recursion limit.
1706
Walter Dörwald58917a62006-03-31 15:26:22 +00001707- Bug #947906: An object oriented interface has been added to the calendar
1708 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001709 called as a script (e.g. via ``python -mcalendar``). Localized month and
1710 weekday names can be ouput (even if an exotic encoding is used) using

1714-----
1715
Neal Norwitz602d3392006-03-31 08:21:40 +00001716- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1717 by using -mieee gcc option.
1718

1720
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001721- Build support for Win64-AMD64 was added.
1722
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001723- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1724
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001725- Patch #881820: look for openpty and forkpty also in libbsd.
1726
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001727- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1728 The zlib module is now builtin on Windows.
1729
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001730- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1731
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001732- Bug #1189330: configure did not correctly determine the necessary
1733 value of LINKCC if python was built with GCC 4.0.
1734
Trent Mick8321b422005-07-26 02:29:21 +00001735- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1736 vulnerability in zlib 1.2.1 and 1.2.2.
1737
Brett Cannon08cd5982005-04-24 22:26:38 +00001738- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1739 flags that change binary compatibility. Changes were also made to
1740 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001741 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001742
Bob Ippolitoed233462005-03-29 13:47:59 +00001743- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1744 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1745 no longer exists). This configure patch makes things right.
1746
Martin v. Löwise2713be2005-03-08 15:03:08 +00001747- Bug #1158607: Build with --disable-unicode again.
1748
Brett Cannon46d96232005-02-16 00:07:19 +00001749- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1750 defined. Discovered as a result of not being able to build on OS X.
1751
Brett Cannon516592f2004-12-07 00:42:59 +00001752- setup.py now uses the directories specified in LDFLAGS using the -L option
1753 and in CPPFLAGS using the -I option for adding library and include
1754 directories, respectively, for compiling extension modules against. This has
1755 led to the core being compiled using the values in CPPFLAGS. It also removes
1756 the need for the special-casing of both DarwinPorts and Fink for darwin since
1757 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1758 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1759 Fink, ``-I/opt/local/include`` for DarwinPorts).
1760
Brett Cannon43802422005-02-10 20:48:03 +00001761- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1762 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1763 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1764 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001766C API
1767-----
1768
Tim Petersc9d78aa2006-03-26 23:27:58 +00001769- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1770 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1771 is obtained via the ``PyObject_`` family, it must be released via the
1772 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1773 always been officially true, but when Python's small-object allocator was
1774 introduced, an attempt was made to cater to a few extension modules
1775 discovered at the time that obtained memory via ``PyObject_New`` but
1776 released it via ``PyMem_DEL``. It's years later, and if such code still
1777 exists it will fail now (probably with segfaults, but calling wrong
1778 low-level memory management functions can yield many symptoms).
1779
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001780- Added a C API for set and frozenset objects.
1781
Raymond Hettinger66517482004-12-03 11:45:13 +00001782- Removed PyRange_New().
1783
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001784- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1785 mapping argument now. This string is used as a mapping table. Byte values
1786 greater than the length of the string and 0xFFFE are treated as undefined
1787 mappings.

1792
Martin v. Löwis4d394df2005-01-23 09:19:22 +00001793- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001794
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001795- Patch #1276356: New resource "urlfetch" is implemented. This enables
1796 even impatient people to run tests that require remote files.
