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
Phillip J. Ebyf7575d02006-07-28 21:12:07 +000015- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
16 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
17 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
18 excessive filesystem operations during imports.
19
Tim Petersbc24eee2006-07-27 01:14:53 +000020- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
21 operations on signed longs that are formally undefined by C.
22 Unfortunately, at least one compiler now cares about that, so complicated
23 the code to make that compiler happy again.
24
Martin v. Löwis982e9fe2006-07-24 12:54:17 +000025- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
26
Martin v. Löwisd22968a2006-07-24 11:54:53 +000027- Patch #1232023: Stop including current directory in search
28 path on Windows.
29
Neal Norwitze1fdb322006-07-21 05:32:28 +000030- Fix some potential crashes found with failmalloc.
31
Neal Norwitze7563102006-07-17 01:00:16 +000032- Fix warnings reported by Klocwork's static analysis tool.
33
Neal Norwitz84be93b2006-07-16 01:50:38 +000034- Bug #1512814, Fix incorrect lineno's when code within a function
35 had more than 255 blank lines.
36
Georg Brandl9dceedb2006-07-12 15:31:17 +000037- Patch #1521179: Python now accepts the standard options ``--help`` and
38 ``--version`` as well as ``/?`` on Windows.
39
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +000040- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +000041 again. Fixing this problem required changing the .pyc magic number.
42 This means that .pyc files generated before 2.5c1 will be regenerated.
43
Tim Peters112aad32006-07-19 00:03:19 +000044- Bug #1524317: Compiling Python ``--without-threads`` failed.
45 The Python core compiles again then, and, in a build without threads, the
46 new ``sys._current_frames()`` returns a dictionary with one entry,
47 mapping the faux "thread id" 0 to the current frame.
48
Ronald Oussoren3075e162006-07-25 20:28:55 +000049- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +000050
Ronald Oussoren3075e162006-07-25 20:28:55 +000051
Neal Norwitza1f10902006-07-12 07:28:29 +000052Library
53-------
54
Tim Peters6f681472006-07-27 23:44:37 +000055- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
56 lost that tests are sorted by name before being run. This rarely
57 matters for well-written tests, but can create baffling symptoms if
58 side effects from one test to the next affect outcomes. ``DocTestFinder``
59 has been changed to sort the list of tests it returns.
60
Martin v. Löwis997ceff2006-07-27 06:38:16 +000061- The distutils version has been changed to 2.5.0.
62
Martin v. Löwis9298eff2006-07-26 12:12:56 +000063- Bug #978833: Really close underlying socket in _socketobject.close.
64
Georg Brandl0619a322006-07-26 07:40:17 +000065- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
66 with title().
67
Georg Brandlcf0c1722006-07-26 07:23:32 +000068- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
69 to recursive calls and call it with the failing package name.
70
Martin v. Löwis0b483032006-07-25 09:53:12 +000071- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
72
Georg Brandlc13c34c2006-07-24 14:09:56 +000073- Patch #1515343: Fix printing of deprecated string exceptions with a
74 value in the traceback module.
75
Greg Ward48fae7a2006-07-23 16:05:51 +000076- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
77
Martin v. Löwis426f4a12006-07-18 17:46:31 +000078- Patch #1524429: Use repr() instead of backticks in Tkinter again.
79
Brett Cannoncaebe222006-07-18 04:41:36 +000080- Bug #1520914: Change time.strftime() to accept a zero for any position in its
81 argument tuple. For arguments where zero is illegal, the value is forced to
82 the minimum value that is correct. This is to support an undocumented but
83 common way people used to fill in inconsequential information in the time
84 tuple pre-2.4.
85
Bob Ippolito5ea4bf12006-07-15 16:53:15 +000086- Patch #1220874: Update the binhex module for Mach-O.
87
Barry Warsawb110bad2006-07-21 14:51:07 +000088- The email package has improved RFC 2231 support, specifically for
89 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
90 (name*0=<blah>) parameter continuations. This may change the types of
91 values returned from email.message.Message.get_param() and friends.
92 Specifically in some cases where non-encoded continuations were used,
93 get_param() used to return a 3-tuple of (None, None, string) whereas now it
94 will just return the string (since non-encoded continuations don't have
95 charset and language parts).
96
97 Also, whereas % values were decoded in all parameter continuations, they are
98 now only decoded in encoded parameter parts.
99
Ronald Oussoren3075e162006-07-25 20:28:55 +0000100- Bug #1517990: IDLE keybindings on MacOS X now work correctly
101
102- Bug #1517996: IDLE now longer shows the default Tk menu when a
103 path browser, class browser or debugger is the frontmost window on MacOS X
104
Barry Warsaw00decd72006-07-27 23:43:15 +0000105- Patch #1520294: Support for getset and member descriptors in types.py,
106 inspect.py, and pydoc.py. Specifically, this allows for querying the type
107 of an object against these built-in types and more importantly, for getting
108 their docstrings printed in the interactive interpreter's help() function.
109
Ronald Oussoren3075e162006-07-25 20:28:55 +0000110
Neal Norwitza1f10902006-07-12 07:28:29 +0000111Extension Modules
112-----------------
113
Thomas Heller1393d6a2006-07-28 21:43:20 +0000114- Patch #1529514: The _ctypes extension is now compiled on more
115 openbsd target platforms.
116
Tim Peters9cab5932006-07-28 00:30:00 +0000117- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
118 a memory leak, affecting pickles and deep copies.
119
Tim Petersbc24eee2006-07-27 01:14:53 +0000120- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000121 Paul Eggert.
122
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000123- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
124
Thomas Hellerce049a02006-07-14 17:51:14 +0000125- Patch #1521817: Index range checking on ctypes arrays containing
126 exactly one element enabled again. This allows iterating over these
127 arrays, without the need to check the array size before.
128
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000129- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000130 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000131 /dev/null in certain cases; this is now fixed.
132
Thomas Heller47d7a062006-07-12 08:43:47 +0000133- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
134 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000135
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000136- Because of a misspelled preprocessor symbol, ctypes was always
137 compiled without thread support; this is now fixed.
138
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000139- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
140 methods now allow their database parameter to be None as the
141 sleepycat API allows.
142
Matt Flemingec926502006-07-28 11:27:27 +0000143- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
144 bluetooth API compared with Linux and FreeBSD.
145
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000146Tests
147-----
148
149- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
150 how long the test file should take to play. Now accepts taking 2.93 secs
151 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
152
Georg Brandl4793aa32006-07-28 18:31:39 +0000153- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
154 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
155 run via ``regrtest.py``. Now they do.

Georg Brandlad29e632006-06-21 17:45:17 +0000162
163Core and builtins
164-----------------
165
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000166- Bug #1441486: The literal representation of -(sys.maxint - 1)
167 again evaluates to a int object, not a long.
168
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000169- Bug #1501934: The scope of global variables that are locally assigned
170 using augmented assignment is now correctly determined.
171
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000172- Bug #927248: Recursive method-wrapper objects can now safely
173 be released.
174
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000175- Bug #1417699: Reject locale-specific decimal point in float()
176 and atof().
177
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000178- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
179 omit a default "error" argument for NULL pointer. This allows
180 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000181
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000182- Bug #1519018: 'as' is now validated properly in import statements.
183
Neal Norwitz28746ab2006-07-09 22:14:42 +0000184- On 64 bit systems, int literals that use less than 64 bits are
185 now ints rather than longs.
186
Neal Norwitzed657552006-07-10 00:04:44 +0000187- Bug #1512814, Fix incorrect lineno's when code at module scope
188 started after line 256.
189
Tim Peters32a83612006-07-10 21:08:24 +0000190- New function ``sys._current_frames()`` returns a dict mapping thread
191 id to topmost thread stack frame. This is for expert use, and is
192 especially useful for debugging application deadlocks. The functionality
193 was previously available in Fazal Majid's ``threadframe`` extension
194 module, but it wasn't possible to do this in a wholly threadsafe way from
195 an extension.
196
Georg Brandlad29e632006-06-21 17:45:17 +0000197Library
198-------
199

201
Tim Peters32a83612006-07-10 21:08:24 +0000202- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000203 environment variable to be set in order to the SDK environment
204 for finding the compiler, include files, etc.
205
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000206- Bug #1515998: Properly generate logical ids for files in bdist_msi.

209
Thomas Woutersadd19112006-07-05 11:03:49 +0000210- string.Template() now correctly handles tuple-values. Previously,
211 multi-value tuples would raise an exception and single-value tuples would
212 be treated as the value they contain, instead.
213
Martin v. Löwisede77f52006-07-03 13:01:35 +0000214- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
215 even if some data are received.
216
Martin v. Löwis45482392006-07-03 12:28:58 +0000217- Bug #1267547: Put proper recursive setup.py call into the
218 spec file generated by bdist_rpm.
219
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000220- Bug #1514693: Update turtle's heading when switching between
221 degrees and radians.
222
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000223- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000224 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000225
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000226- Bug #1514703: Only setup canvas window in turtle when the canvas
227 is created.
228

233 attribute values.
234
235- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
236 sgmllib ('[' and ']' were not accepted).
237
Georg Brandl1be63af2006-06-28 20:23:25 +0000238- Fix a bug in the turtle module's end_fill function.
239
Brett Cannon53ab5b72006-06-22 16:49:14 +0000240- Bug #1510580: The 'warnings' module improperly required that a Warning
241 category be either a types.ClassType and a subclass of Warning. The proper
242 check is just that it is a subclass with Warning as the documentation states.
243
Georg Brandlad29e632006-06-21 17:45:17 +0000244- The compiler module now correctly compiles the new try-except-finally
245 statement (bug #1509132).
246
Neal Norwitz60373cd2006-06-22 06:30:50 +0000247- The wsgiref package is now installed properly on Unix.
248
Vinay Sajip28e57612006-07-01 10:45:20 +0000249- A bug was fixed in logging.config.fileConfig() which caused a crash on
250 shutdown when fileConfig() was called multiple times.
251
Gerhard Häring762fbd32006-07-02 17:48:30 +0000252- The sqlite3 module did cut off data from the SQLite database at the first
253 null character before sending it to a custom converter. This has been fixed
254 now.
255
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000256Extension Modules
257-----------------
258
Tim Peters112aad32006-07-19 00:03:19 +0000259- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
260 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
261 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000262
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000263- Assigning None to pointer type fields in ctypes structures possible
264 overwrote the wrong fields, this is fixed now.
265
266- Fixed a segfault in _ctypes when ctypes.wintypes were imported
267 on non-Windows platforms.
268
269- Bug #1518190: The ctypes.c_void_p constructor now accepts any
270 integer or long, without range checking.
271
272- Patch #1517790: It is now possible to use custom objects in the ctypes
273 foreign function argtypes sequence as long as they provide a from_param
274 method, no longer is it required that the object is a ctypes type.
275
276- The '_ctypes' extension module now works when Python is configured
277 with the --without-threads option.
278
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000279- Bug #1513646: os.access on Windows now correctly determines write
280 access, again.
281
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000282- Bug #1512695: cPickle.loads could crash if it was interrupted with
283 a KeyboardInterrupt.
284
Neal Norwitza12aa882006-07-06 06:45:08 +0000285- Bug #1296433: parsing XML with a non-default encoding and
286 a CharacterDataHandler could crash the interpreter in pyexpat.

291-----
292
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000293- Automate Windows build process for the Win64 SSL module.
294
Tim Peters32a83612006-07-10 21:08:24 +0000295- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000296 Previously, the slight difference could cause compilation errors of the
297 'zlib' module on systems with more than one version of zlib.
298
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000299- The MSI compileall step was fixed to also support a TARGETDIR
300 with spaces in it.

Neal Norwitzb15ac312006-06-29 04:10:08 +0000308Tests
309-----
310
311- Call os.waitpid() at the end of tests that spawn child processes in order

Anthony Baxter51bcb682006-04-05 14:51:42 +0000326
Anthony Baxterd1136802006-06-19 12:04:15 +0000327*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000328
329Core and builtins
330-----------------
331
Georg Brandla56b9152006-06-19 06:35:54 +0000332- Patch #1507676: Error messages returned by invalid abstract object operations
333 (such as iterating over an integer) have been improved and now include the
334 type of the offending object to help with debugging.
335
Brett Cannonea3912b2006-06-13 21:46:41 +0000336- Bug #992017: A classic class that defined a __coerce__() method that returned
337 its arguments swapped would infinitely recurse and segfault the interpreter.
338
Neal Norwitz909eb122006-06-12 02:13:21 +0000339- Fix the socket tests so they can be run concurrently.
340
Neal Norwitzb9845e72006-06-12 02:11:18 +0000341- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000342 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000343
Brett Cannon22565aa2006-06-09 22:31:23 +0000344- Bug #532646: object.__call__() will continue looking for the __call__
345 attribute on objects until one without one is found. This leads to recursion
346 when you take a class and set its __call__ attribute to an instance of the
347 class. Originally fixed for classic classes, but this fix is for new-style.
348 Removes the infinite_rec_3 crasher.
349
Georg Brandl24250812006-06-09 18:45:48 +0000350- The string and unicode methods startswith() and endswith() now accept
351 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
352
Brett Cannonde3b0522006-06-08 17:00:45 +0000353- Buffer objects, at the C level, never used the char buffer
354 implementation even when the char buffer for the wrapped object was
355 explicitly requested (originally returned the read or write buffer).
356 Now a TypeError is raised if the char buffer is not present but is
357 requested.
358
Georg Brandlddbaa662006-06-04 21:56:52 +0000359- Patch #1346214: Statements like "if 0: suite" are now again optimized
360 away like they were in Python 2.4.
361
Georg Brandlb7c8f542006-05-27 12:30:25 +0000362- Builtin exceptions are now full-blown new-style classes instead of
363 instances pretending to be classes, which speeds up exception handling
364 by about 80% in comparison to 2.5a2.
365
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000366- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
367 Unicode 4.1.
368
Georg Brandlf4ef1162006-05-26 18:03:31 +0000369- Patch #921466: sys.path_importer_cache is now used to cache valid and
370 invalid file paths for the built-in import machinery which leads to
371 fewer open calls on startup.
372
Tim Peters696cf432006-05-24 21:10:40 +0000373- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
374 of-2 bases. The largest speedup is for inputs with about 1000 decimal
375 digits. Conversion from non-power-of-2 bases remains quadratic-time in
376 the number of input digits (it was and remains linear-time for bases
377 2, 4, 8, 16 and 32).
378
Tim Petersb713ec22006-05-23 18:45:30 +0000379- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
380 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
381 an integer close to ``sys.maxint``. This was repaired by patch
382 #1335972, which also gives a nice speedup.
383
Richard Jonescebbefc2006-05-23 18:28:17 +0000384- Patch #1337051: reduced size of frame objects.
385
386- PyErr_NewException now accepts a tuple of base classes as its
387 "base" parameter.
388
Richard Jones7c88dcc2006-05-23 10:37:38 +0000389- Patch #876206: function call speedup by retaining allocated frame
390 objects.
391
Georg Brandl7b90e162006-05-18 07:01:27 +0000392- Bug #1462152: file() now checks more thoroughly for invalid mode
393 strings and removes a possible "U" before passing the mode to the
394 C library function.
395
Neal Norwitz1004a532006-05-15 07:17:23 +0000396- Patch #1488312, Fix memory alignment problem on SPARC in unicode
397
Neal Norwitz373f0a72006-05-15 07:04:36 +0000398- Bug #1487966: Fix SystemError with conditional expression in assignment
399
Martin v. Löwis879768d2006-05-11 13:28:43 +0000400- WindowsError now has two error code attributes: errno, which carries
401 the error values from errno.h, and winerror, which carries the error
402 values from winerror.h. Previous versions put the winerror.h values
403 (from GetLastError()) into the errno attribute.
404
Martin v. Löwis77736712006-05-04 05:51:03 +0000405- Patch #1475845: Raise IndentationError for unexpected indent.
406
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000407- Patch #1479181: split open() and file() from being aliases for each other.
408
Tim Peters44bd9862006-06-01 13:49:23 +0000409- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
410 methods were always silently ignored by dictionaries when comparing keys.
411 They are now passed through (except when using the C API function
412 ``PyDict_GetItem()``, whose semantics did not change).
413
414- Bug #1456209: In some obscure cases it was possible for a class with a
415 custom ``__eq__()`` method to confuse dict internals when class instances
416 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
417 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000419Extension Modules
420-----------------
421
Trent Mick960a3f82006-06-28 20:30:41 +0000422- Bug #1295808: expat symbols should be namespaced in pyexpat
423
424- Patch #1462338: Upgrade pyexpat to expat 2.0.0
425
Brett Cannon6ee7d012006-06-08 16:23:04 +0000426- Change binascii.hexlify to accept a read-only buffer instead of only a char
427 buffer and actually follow its documentation.
428
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000429- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
430
Nick Coghlanc649ec52006-05-29 12:43:05 +0000431- Patch #1478788 (modified version): The functional extension module has
432 been renamed to _functools and a functools Python wrapper module added.
433 This provides a home for additional function related utilities that are
434 not specifically about functional programming. See PEP 309.
435
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000436- Patch #1493701: performance enhancements for struct module.
437
Georg Brandl378d5922006-05-17 14:26:50 +0000438- Patch #1490224: time.altzone is now set correctly on Cygwin.
439
Georg Brandl8d3342b2006-05-16 07:38:27 +0000440- Patch #1435422: zlib's compress and decompress objects now have a
441 copy() method.
442
Andrew MacIntyre92913322006-06-13 15:04:24 +0000443- Patch #1454481: thread stack size is now tunable at runtime for thread
444 enabled builds on Windows and systems with Posix threads support.
445
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000446- On Win32, os.listdir now supports arbitrarily-long Unicode path names
447 (up to the system limit of 32K characters).
448
449- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
450 As a result, these functions now raise WindowsError instead of OSError.
451
Tim Peters7a822da2006-05-25 21:50:17 +0000452- ``time.clock()`` on Win64 should use the high-performance Windows
453 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
454 Windows platforms).
455
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000456- Calling Tk_Init twice is refused if the first call failed as that
457 may deadlock.
458
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000459- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
460 accept it without potentially using an uninitialized pointer.
461
462- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
463 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
464 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000465
Gregory P. Smith372b5832006-06-05 18:48:21 +0000466- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000467 [pybsddb project SF patch number 1466734]
468
Gregory P. Smith372b5832006-06-05 18:48:21 +0000469- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
470 parameter is supplied. [SF pybsddb bug #1477863]
471
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000472- bsddb: the __len__ method of a DB object has been fixed to return correct
473 results. It could previously incorrectly return 0 in some cases.
474 Fixes SF bug 1493322 (pybsddb bug 1184012).
475
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000476- bsddb: the bsddb.dbtables Modify method now raises the proper error and
477 aborts the db transaction safely when a modifier callback fails.
478 Fixes SF python patch/bug #1408584.
479
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000480- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000481 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000482 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
483 database calls that would previously deadlock. [SF python bug #775414]
484
Vinay Sajip28e57612006-07-01 10:45:20 +0000485- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000486
Walter Dörwald4994d952006-06-19 08:07:50 +0000487- Patch #1506645: add Python wrappers for the curses functions
488 is_term_resized, resize_term and resizeterm.

491-------
492
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000493- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
494 functions.
495
Martin v. Löwis3798da02006-06-17 18:44:27 +0000496- Patch #812986: Update turtle output even if not tracing.
497
Vinay Sajip28e57612006-07-01 10:45:20 +0000498- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000499 Tkinter.BaseWidget.
500
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000501- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
502
Martin v. Löwis337487e2006-06-17 09:15:14 +0000503- Patch #763580: Add name and value arguments to Tkinter variable
504 classes.
505
Georg Brandl83cc0d02006-06-14 08:50:03 +0000506- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
507 mime.types file for determining MIME types.
508
Georg Brandl2605ca82006-06-14 06:08:31 +0000509- Bug #1339007: Shelf objects now don't raise an exception in their
510 __del__ method when initialization failed.
511
Martin v. Löwisd8251432006-06-14 05:21:04 +0000512- Patch #1455898: The MBCS codec now supports the incremental mode for
513 double-byte encodings.
514
Tim Peters43898b42006-06-14 04:09:25 +0000515- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
516 guarantee that adjacent triples in the return list always describe
517 non-adjacent blocks. Previously, a pair of matching blocks could end
518 up being described by multiple adjacent triples that formed a partition
519 of the matching pair.
520
Greg Ward0e0c9f42006-06-11 16:24:11 +0000521- Bug #1498146: fix optparse to handle Unicode strings in option help,
522 description, and epilog.
523
Greg Wardd1c797e2006-06-11 14:42:41 +0000524- Bug #1366250: minor optparse documentation error.
525
Greg Ward7f547402006-06-11 00:40:49 +0000526- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
527 clarify docs.
528
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000529- The wsgiref package has been added to the standard library.
530
Nick Coghlan676725d2006-06-08 13:54:49 +0000531- The functions update_wrapper() and wraps() have been added to the functools
532 module. These make it easier to copy relevant metadata from the original
533 function when writing wrapper functions.
534
Tim Petersd6a9eef2006-06-05 01:48:21 +0000535- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
536 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000537
Martin v. Löwis3f767792006-06-04 19:36:28 +0000538- Patch #1359618: Speed up charmap encoder by using a trie structure
539 for lookup.
540
Tim Petersd609b1a2006-06-02 23:22:51 +0000541- The functions in the ``pprint`` module now sort dictionaries by key
542 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
543 if and only if its display required more than one line, although that
544 wasn't documented. The new behavior increases predictability; e.g.,
545 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
546
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000547- Patch #1497027: try HTTP digest auth before basic auth in urllib2
548 (thanks for J. J. Lee).
549
Georg Brandl2b330372006-05-28 20:23:12 +0000550- Patch #1496206: improve urllib2 handling of passwords with respect to
551 default HTTP and HTTPS ports.
552
George Yoshidaf3c65de2006-05-28 16:39:09 +0000553- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
554
Bob Ippolito7298f272006-05-23 18:43:47 +0000555- Patch #1281707: speed up gzip.readline.
556
Georg Brandlb89316f2006-05-17 15:51:16 +0000557- Patch #1180296: Two new functions were added to the locale module:
558 format_string() to get the effect of "format % items" but locale-aware,
559 and currency() to format a monetary number with currency sign.
560
Georg Brandle3a25832006-05-17 14:56:04 +0000561- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
562 and several features added, such as speed and geometry control.
563
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000564- Patch #1488881: add support for external file objects in bz2 compressed
565 tarfiles.
566
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000567- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
568 stdout arguments, making it possible to redirect input and output
569 for remote debugging.
570
571- Patch #1484695: Update the tarfile module to version 0.8. This fixes
572 a couple of issues, notably handling of long file names using the
573 GNU LONGNAME extension.
574
575- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
576 new flag when ``name`` is already the name of an option flag.
577
578- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
579 package.
580
581- Patch #1472854: make the rlcompleter.Completer class usable on non-
582 UNIX platforms.
583
584- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
585
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000586- Bug #1472827: correctly escape newlines and tabs in attribute values in
587 the saxutils.XMLGenerator class.

Martin v. Löwis45294a92006-04-18 06:24:08 +0000634- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
635
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000636- All uses of PyStructSequence_InitType have been changed to initialize
637 the type objects only once, even if the interpreter is initialized
638 multiple times.
639
Neal Norwitz61546162006-04-14 05:20:28 +0000640- Bug #1454485, array.array('u') could crash the interpreter. This was
641 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
642 to unicode when it didn't make sense. 'u#' now requires a unicode string.
643
644- Py_UNICODE is unsigned. It was always documented as unsigned, but
645 due to a bug had a signed value in previous versions.
646
Tim Peters3a5e8b12006-04-11 01:44:07 +0000647- Patch #837242: ``id()`` of any Python object always gives a positive
648 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
649 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000650 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000651 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000652
Tim Peters3a5e8b12006-04-11 01:44:07 +0000653 def __hash__(self):
654 return id(self) # WRONG
655
656 because a hash result must be a (short) Python int but it was always
657 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000658 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000659 was always usable as a hash value before this patch. That's no longer
660 necessarily so.
661
662- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000663 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000664 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000665 #1454844)
666
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000667- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
668 involving generators that have paused outside of any ``try`` or ``with``
669 blocks. (In 2.5a1, a paused generator that was part of a reference
670 cycle could not be garbage collected, regardless of whether it was
671 paused in a ``try`` or ``with`` block.)

677 is a macro.
678
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000679- Bug #1467952: os.listdir() now correctly raises an error if readdir()
680 fails with an error condition.
681
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000682- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
683
684- Bug #1117761: bsddb.*open() no longer raises an exception when using
685 the cachesize parameter.
686
687- Bug #1149413: bsddb.*open() no longer raises an exception when using
688 a temporary db (file=None) with the 'n' flag to truncate on open.
689
690- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
691 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000692
Armin Rigoa9017c32006-04-19 11:50:27 +0000693- Patch #1062014: AF_UNIX sockets under Linux have a special
694 abstract namespace that is now fully supported.
695
Anthony Baxter51bcb682006-04-05 14:51:42 +0000696Library
697-------
698
Peter Astrand7d1d4362006-07-14 14:04:45 +0000699- Bug #1223937: subprocess.CalledProcessError reports the exit status
700 of the process using the returncode attribute, instead of
701 abusing errno.
702
Tim Peters711bf302006-04-25 03:31:36 +0000703- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
704 a doctest to be skipped (the code is not run, and the expected output
705 or exception is ignored).
706
Nick Coghlanda2268f2006-04-24 04:37:15 +0000707- Fixed contextlib.nested to cope with exceptions being raised and
708 caught inside exit handlers.
709
Greg Wardab05edc2006-04-23 03:47:58 +0000710- Updated optparse module to Optik 1.5.1 (allow numeric constants in
711 hex, octal, or binary; add ``append_const`` action; keep going if
712 gettext cannot be imported; added ``OptionParser.destroy()`` method;
713 added ``epilog`` for better help generation).
714
Tim Peters21fbd572006-04-21 21:18:10 +0000715- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
716 called from a thread spawned as a side effect of importing a module.
717
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000718- The pydoc module now supports documenting packages contained in
719 .zip or .egg files.
720
721- The pkgutil module now has several new utility functions, such
722 as ``walk_packages()`` to support working with packages that are either
723 in the filesystem or zip files.
724
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000725- The mailbox module can now modify and delete messages from
726 mailboxes, in addition to simply reading them. Thanks to Gregory
727 K. Johnson for writing the code, and to the 2005 Google Summer of
728 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000729
Tim Petersc7605f22006-04-17 21:12:33 +0000730- The ``__del__`` method of class ``local`` in module ``_threading_local``
731 returned before accomplishing any of its intended cleanup.
732
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000733- Patch #790710: Add breakpoint command lists in pdb.
734
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000735- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +0000737- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
738
Anthony Baxtere29002c2006-04-12 12:07:31 +0000739- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
740 Windows. Bug #1469163.
741
Phillip J. Eby47032112006-04-11 01:07:43 +0000742- The warnings, linecache, inspect, traceback, site, and doctest modules
743 were updated to work correctly with modules imported from zipfiles or
744 via other PEP 302 __loader__ objects.
745
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000746- Patch #1467770: Reduce usage of subprocess._active to processes which
747 the application hasn't waited on.
748
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000749- Patch #1462222: Fix Tix.Grid.
750
Neal Norwitza31bf182006-04-09 03:35:43 +0000751- Fix exception when doing glob.glob('anything*/')
752
Skip Montanaro262fb922006-04-21 02:31:07 +0000753- The pstats.Stats class accepts an optional stream keyword argument to
754 direct output to an alternate file-like object.
755
Anthony Baxter51bcb682006-04-05 14:51:42 +0000756Build
757-----
758
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000759- The Makefile now has a reindent target, which runs reindent.py on
760 the library.
761
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000762- Patch #1470875: Building Python with MS Free Compiler
763
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000764- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000765
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000766- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
767 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000768 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000769 CXX from --with-cxx-main, see description in README.
770
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000771- Patch #1429775: Link extension modules with the shared libpython.
772
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000773- Fixed a libffi build problem on MIPS systems.
774
Tim Peters8931ff12006-05-13 23:28:20 +0000775- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
776 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
777 and "%zu" for unsigned integers of type ``size_t``.
778
Anthony Baxter51bcb682006-04-05 14:51:42 +0000779Tests
780-----
781
Nick Coghlanda2268f2006-04-24 04:37:15 +0000782- test_contextlib now checks contextlib.nested can cope with exceptions
783 being raised and caught inside exit handlers.
784
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000785- test_cmd_line now checks operation of the -m and -c command switches
786
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000787- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
788 it separately and by hand. It also wasn't cleaning up its changes to
789 the current Decimal context.
790
Thomas Woutersabd08882006-04-26 15:53:30 +0000791- regrtest.py now has a -M option to run tests that test the new limits of
792 containers, on 64-bit architectures. Running these tests is only sensible
793 on 64-bit machines with more than two gigabytes of memory. The argument
794 passed is the maximum amount of memory for the tests to use.

803-------------
804
Tim Petersb06d28c2006-05-12 01:57:59 +0000805- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
806
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000807- PEP 343: Added Context Types section to the library reference
808 and attempted to bring other PEP 343 related documentation into
809 line with the implementation and/or python-dev discussions.
810
Tim Peters8dc73d22006-04-24 02:03:16 +0000811- Bug #1337990: clarified that ``doctest`` does not support examples
812 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000820Core and builtins
821-----------------
822
Nick Coghlan43832302006-04-23 17:04:07 +0000823- PEP 338: -m command line switch now delegates to runpy.run_module
824 allowing it to support modules in packages and zipfiles
825
Martin v. Löwisc661b882006-04-20 04:54:23 +0000826- On Windows, .DLL is not an accepted file name extension for
827 extension modules anymore; extensions are only found if they
828 end in .PYD.
829
Martin v. Löwisea62d252006-04-03 10:56:49 +0000830- Bug #1421664: sys.stderr.encoding is now set to the same value as
831 sys.stdout.encoding.
832
Neal Norwitz92e212f2006-04-03 04:48:37 +0000833- __import__ accepts keyword arguments.
834
Georg Brandlccadf842006-03-31 18:54:53 +0000835- Patch #1460496: round() now accepts keyword arguments.
836
Anthony Baxter262c00a2006-03-30 10:53:17 +0000837- Fixed bug #1459029 - unicode reprs were double-escaped.
838
Hye-Shik Changd478f342006-03-23 12:32:36 +0000839- Patch #1396919: The system scope threads are reenabled on FreeBSD
840 5.4 and later versions.
841
Neal Norwitze98ccf62006-03-23 05:39:47 +0000842- Bug #1115379: Compiling a Unicode string with an encoding declaration
843 now gives a SyntaxError.
844
Georg Brandlabd1ff82006-03-18 07:59:59 +0000845- Previously, Python code had no easy way to access the contents of a
846 cell object. Now, a ``cell_contents`` attribute has been added
847 (closes patch #1170323).
848
Tim Peterscf79aac2006-03-16 01:14:46 +0000849- Patch #1123430: Python's small-object allocator now returns an arena to
850 the system ``free()`` when all memory within an arena becomes unused
851 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
852 freed. Some applications will see a drop in virtual memory size now,
853 especially long-running applications that, from time to time, temporarily
854 use a large number of small objects. Note that when Python returns an
855 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000856 platform C library will in turn return that memory to the operating system.
857 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000858 appears to be effective at least on Microsoft C and gcc-based systems.
859 Thanks to Evan Jones for hard work and patience.
860
Georg Brandl533ff6f2006-03-08 18:09:27 +0000861- Patch #1434038: property() now uses the getter's docstring if there is
862 no "doc" argument given. This makes it possible to legitimately use
863 property() as a decorator to produce a read-only property.
864
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000865- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
866 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
867 of requiring an int or long in slicing and a few other contexts, enabling
868 other objects (e.g. Numeric Python's integers) to be used as slice indices.
869
Neal Norwitz995acdf2006-03-07 05:01:00 +0000870- Fixed various bugs reported by Coverity's Prevent tool.
871
Brett Cannonbf364092006-03-01 04:25:17 +0000872- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
873 new exception base class, BaseException, which has a new message attribute.
874 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
875 Raising a string exception now raises a DeprecationWarning.
876
Thomas Woutersfb609f42006-02-28 16:37:25 +0000877- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
878 explicitly relative, using 'from .module import name' to mean 'from the same
879 package as this module is in. Imports without dots still default to the
880 old relative-then-absolute, unless 'from __future__ import
881 absolute_import' is used.
882
Brett Cannona7446e32006-02-27 23:39:10 +0000883- Properly check if 'warnings' raises an exception (usually when a filter set
884 to "error" is triggered) when raising a warning for raising string
885 exceptions.
886
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000887- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000888 The name was removed from Include/code.h.
889
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000890- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000891
Guido van Rossum1968ad32006-02-25 22:38:04 +0000892- Patch 1433928:
893 - The copy module now "copies" function objects (as atomic objects).
894 - dict.__getitem__ now looks for a __missing__ hook before raising
895 KeyError.
896
Tim Peters84ef21c2006-02-28 20:39:06 +0000897- PEP 343: with statement implemented. Needs ``from __future__ import
898 with_statement``. Use of 'with' as a variable will generate a warning.
899 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000900 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000901 The following objects have __context__ methods:
902 - The built-in file type.
903 - The thread.LockType type.
904 - The following types defined by the threading module:
905 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
906 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000907
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000908- Fix the encodings package codec search function to only search
909 inside its own package. Fixes problem reported in patch #1433198.
910
911 Note: Codec packages should implement and register their own
912 codec search function. PEP 100 has the details.
913
Tim Peters9ea89d22006-06-04 03:26:02 +0000914- PEP 353: Using ``Py_ssize_t`` as the index type.
915
916- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
917 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
918 now allow Python to make use of memory blocks exceeding 2**32 bytes for
919 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
920 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000921
Neal Norwitzfc76d632006-01-10 06:03:13 +0000922- Patch #1400181, fix unicode string formatting to not use the locale.
923 This is how string objects work. u'%f' could use , instead of .
924 for the decimal point. Now both strings and unicode always use periods.
925
Neal Norwitz671b9e32006-01-09 07:07:12 +0000926- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
927 configure would break checking curses.h.
928
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000929- Bug #959576: The pwd module is now builtin. This allows Python to be
930 built on UNIX platforms without $HOME set.

Neal Norwitzc10978f2005-12-19 06:07:16 +0000932- Bug #1072182, fix some potential problems if characters are signed.
933
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000934- Bug #889500, fix line number on SyntaxWarning for global declarations.
935
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000936- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
937
Neal Norwitze7214a12005-12-18 05:03:17 +0000938- Support for converting hex strings to floats no longer works.
939 This was not portable. float('0x3') now raises a ValueError.
940
Barry Warsaw2a38a862005-12-18 01:27:35 +0000941- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000942 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000943 is now displayed in interactive prompt banner.
944
Georg Brandlfa166682005-12-17 21:45:17 +0000945- Implementation of PEP 341 - Unification of try/except and try/finally.
946 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000947 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000948
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000949- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
950 now encodes backslash correctly.
951
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000952- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
953
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000954- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000955 and long longs.
956
Neal Norwitz67715f02005-11-09 06:59:35 +0000957- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000958 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000959 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000960
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000961- Replaced most Unicode charmap codecs with new ones using the
962 new Unicode translate string feature in the builtin charmap
963 codec; the codecs were created from the mapping tables available
964 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
965 encodings now include a mapping for the Apple logo)
966
Tim Peterse3547fd2005-12-16 23:13:57 +0000967- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000968
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000969- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000970
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000971- A new AST parser implementation was completed. The abstract
972 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000973 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000974
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000975- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000976 The following code now raises a SyntaxError: foo(a = i for i in range(10))
977
Neal Norwitz708e51a2005-10-03 04:48:15 +0000978- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
979
Neal Norwitz11bd1192005-10-03 00:54:56 +0000980- SF Bug #887946: fix segfault when redirecting stdin from a directory.
981 Provide a warning when a directory is passed on the command line.
982
Neal Norwitz40d37812005-10-02 01:48:49 +0000983- Fix segfault with invalid coding.
984
985- SF bug #772896: unknown encoding results in MemoryError.
986
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000987- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000988 supported a __len__() method which evaluated to False when the iterator
989 was empty.
990
Guido van Rossum630db602005-09-20 18:49:54 +0000991- On 64-bit platforms, when __len__() returns a value that cannot be
992 represented as a C int, raise OverflowError.
993
Skip Montanarof8948ca2005-09-19 03:54:46 +0000994- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000995 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000996
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000997- SF bug #893549: parsing keyword arguments was broken with a few format
998 codes.
999
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001000- Changes donated by Elemental Security to make it work on AIX 5.3
1001 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1002 bug #105470: test_pwd fails on 64bit system (Opteron).
1003
Guido van Rossum539c6622005-09-14 17:49:54 +00001004- Changes donated by Elemental Security to make it work on HP-UX 11 on
1005 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1006
Georg Brandl4550b8d2005-08-26 06:43:52 +00001007- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001008 (fixes bug #1119418).
1009
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001010- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1011
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001012- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1013 exceptions that cause a function to exit.
1014
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001015- The implementation of set() and frozenset() was revised to use its
1016 own internal data structure. Memory consumption is reduced by 1/3
1017 and there are modest speed-ups as well. The API is unchanged.
1018
Tim Petersde7990b2005-07-17 23:45:23 +00001019- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1020
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001021- SF bug #1229429: PyObject_CallMethod failed to decrement some
1022 reference counts in some error exit cases.
1023
Tim Petersecc6e6a2005-07-10 22:30:55 +00001024- SF bug #1185883: Python's small-object memory allocator took over
1025 a block managed by the platform C library whenever a realloc specified
1026 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001027 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001028 portable way to copy data from the C-managed block into Python's
1029 small-object space without risking a memory fault. Python's small-object
1030 realloc now leaves such blocks under the control of the platform C
1031 realloc.
1032
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001033- SF bug #1232517: An overflow error was not detected properly when
1034 attempting to convert a large float to an int in os.utime().
1035
Raymond Hettinger3296e692005-06-29 23:29:56 +00001036- SF bug #1224347: hex longs now print with lowercase letters just
1037 like their int counterparts.
1038
Michael W. Hudson188d4362005-06-20 16:52:57 +00001039- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1040 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1041 interpreter states; back out that fix and do a better job (see
1042 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1043 for a longer write-up of the problem).
1044
Michael W. Hudsondf888462005-06-03 14:41:55 +00001045- SF patch #1180995: marshal now uses a binary format by default when
1046 serializing floats.
1047
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001048- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1049 the routines that promise to produce IEEE 754 binary representations
1050 of floats now simply copy bytes around.
1051
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001052- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1053 278.
1054
Brett Cannonc3647ac2005-04-26 03:45:26 +00001055- patch #1109424: int, long, float, complex, and unicode now check for the
1056 proper magic slot for type conversions when subclassed. Previously the
1057 magic slot was ignored during conversion. Semantics now match the way
1058 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001059 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001060 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001061 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001062
Barry Warsawc8d907c2005-04-19 23:43:40 +00001063- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1064 NULL, now raise an AttributeError when attempting to set or delete the
1065 attribute. Previously a TypeError was raised, but this was inconsistent
1066 with the equivalent pure-Python implementation.
1067
Michael W. Hudson774479c2005-04-18 08:46:17 +00001068- It is now safe to call PyGILState_Release() before
1069 PyEval_InitThreads() (note that if there is reason to believe there
1070 are multiple threads around you still must call PyEval_InitThreads()
1071 before using the Python API; this fix is for extension modules that
1072 have no way of knowing if Python is multi-threaded yet).
1073
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001074- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1075 disabled caused a crash.
1076
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001077- Bug #1165306: instancemethod_new allowed the creation of a method
1078 with im_class == im_self == NULL, which caused a crash when called.
1079
Tim Petersecc6e6a2005-07-10 22:30:55 +00001080- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001081 fixes the crash seen in bug #1165761
1082
Raymond Hettinger96229b12005-03-11 06:49:40 +00001083- Added two new builtins, any() and all().
1084
Brett Cannon409d8f22005-03-05 06:47:57 +00001085- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001086 (e.g., ``class C(): pass`` is no longer a syntax error).
1087 Patch #1176012 added support to the 'parser' module and 'compiler' package
1088 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001089
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001090- Patch #1115086: Support PY_LONGLONG in structmember.
1091
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001092- Bug #1155938: new style classes did not check that __init__() was
1093 returning None.
1094
Tim Petersecc6e6a2005-07-10 22:30:55 +00001095- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001096 ('\') with a specific error message.
1097
Martin v. Löwisff232d72005-03-03 09:24:38 +00001098- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1099
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001100- Bug #1124295: the __name__ attribute of file objects was
1101 inadvertently made inaccessible in restricted mode.
1102
Tim Petersecc6e6a2005-07-10 22:30:55 +00001103- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001104 an ferror() call.
1105
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001106- min() and max() now support key= arguments with the same meaning as in
1107 list.sort().
1108
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001109- The peephole optimizer now performs simple constant folding in expressions:
1110 (2+3) --> (5).
1111
Raymond Hettingera422c342005-01-11 03:03:27 +00001112- set and frozenset objects can now be marshalled. SF #1098985.
1113
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001114- Bug #1077106: Poor argument checking could cause memory corruption
1115 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001116
Jeremy Hyltonab630502005-02-04 18:44:06 +00001117- The parser did not complain about future statements in illegal
1118 positions. It once again reports a syntax error if a future
1119 statement occurs after anything other than a doc string.
1120
Neil Schemenauercf52c072005-08-12 17:34:58 +00001121- Change the %s format specifier for str objects so that it returns a
1122 unicode instance if the argument is not an instance of basestring and
1123 calling __str__ on the argument returns a unicode instance.
1124
Tim Petersf4e69282006-02-27 17:15:31 +00001125- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1126 current thread state when the auto-GIL-state machinery knows about
1127 it (since the thread state is being deleted, continuing to remember it
1128 can't help, but can hurt if another thread happens to get created with
1129 the same thread id).
1130
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001131Extension Modules
1132-----------------
1133
Georg Brandl43f08a82006-03-31 18:01:16 +00001134- Patch #1380952: fix SSL objects timing out on consecutive read()s

1137
Anthony Baxterfa869072006-03-20 05:21:58 +00001138- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1139 In addition, the existing ulaw code was updated.
1140
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001141- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001142 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001143
Neal Norwitz10be10c2006-03-16 06:50:13 +00001144- Everything under lib-old was removed. This includes the following modules:
1145 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001146 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001147 util, whatsound, whrandom, zmod
1148
1149- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1150
1151- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001152 is deprecated. The undocumented re.engine variable no longer exists.
1153
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001154- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1155 SS2 (single-shift 2) escape sequences correctly.
1156
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001157- The unicodedata module was updated to the 4.1 version of the Unicode
1158 database. The 3.2 version is still available as unicodedata.db_3_2_0
1159 for applications that require this specific version (such as IDNA).
1160
Neal Norwitzb62c4332006-03-04 18:35:47 +00001161- The timing module is no longer built by default. It was deprecated
1162 in PEP 4 in Python 2.0 or earlier.
1163
Guido van Rossum1968ad32006-02-25 22:38:04 +00001164- Patch 1433928: Added a new type, defaultdict, to the collections module.
1165 This uses the new __missing__ hook behavior added to dict (see above).
1166
Georg Brandldbd83392006-02-20 09:42:33 +00001167- Bug #854823: socketmodule now builds on Sun platforms even when
1168 INET_ADDRSTRLEN is not defined.
1169
Georg Brandlf4f44152006-02-18 22:29:33 +00001170- Patch #1393157: os.startfile() now has an optional argument to specify
1171 a "command verb" to invoke on the file.
1172
Neal Norwitz082b2df2006-02-07 07:04:46 +00001173- Bug #876637, prevent stack corruption when socket descriptor
1174 is larger than FD_SETSIZE.
1175
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001176- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1177 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1178 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1179
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001180- Patch #1422385: The nis module now supports access to domains other
1181 than the system default domain.
1182
Martin v. Löwis14694662006-02-03 12:54:16 +00001183- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1184 are reported, the limit on path name lengths is removed, and stat reports
1185 WindowsError now (instead of OSError).
1186
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001187- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
1188
Neal Norwitz62a21122006-01-25 05:21:55 +00001189- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
1190 before the env.
1191

1323 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001324
Nick Coghlan43832302006-04-23 17:04:07 +00001325- PEP 338: new module runpy defines a run_module function to support
1326 executing modules which provide access to source code or a code object
1327 via the PEP 302 import mechanisms.
1328

1337 in attribute values.
1338
Anthony Baxterc51ee692006-04-01 00:57:31 +00001339- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001340 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001341 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001342 module will not be built.
1343
Tim Petersc17976e2006-04-01 00:26:53 +00001344- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1345 aren't officially supported here, and trying to use them will probably
1346 raise an exception some day. But dicts have been allowed, and "mostly
1347 worked", so support for them won't go away without warning.
1348
Georg Brandl338ef7d2006-03-31 18:42:16 +00001349- Bug #1445068: getpass.getpass() can now be given an explicit stream

1367
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001368- email 4.0 package now integrated. This is largely the same as the email 3.0
1369 package that was included in Python 2.3, except that PEP 8 module names are
1370 now used (e.g. mail.message instead of email.Message). The MIME classes
1371 have been moved to a subpackage (e.g. email.mime.text instead of
1372 email.MIMEText). The old names are still supported for now. Several
1373 deprecated Message methods have been removed and lots of bugs have been
1374 fixed. More details can be found in the email package documentation.
1375
Walter Dörwald40108c92006-03-27 08:15:44 +00001376- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1377 (a subclass of tuple) that provides incremental decoders and encoders
1378 (a way to use stateful codecs without the stream API). Python functions
1379 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1380 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1381 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001383- Patch #1359365: Calling next() on a closed StringIO.String object raises
1384 a ValueError instead of a StopIteration now (like file and cString.String do).
1385 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1386 called before (like file and StringIO.StringIO do).

Neal Norwitz338e7862005-12-23 21:27:46 +00001455- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
1456 LoadError as documented, instead of IOError. For compatibility,
1457 LoadError subclasses IOError.
1458
Brett Cannon3cbd0382005-12-16 22:49:23 +00001459- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001460 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1461 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1462 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1463 Ronald L. Rivest offered this advice for Python:
1464
1465 "The consensus of researchers in this area (at least as
1466 expressed at the NIST Hash Function Workshop 10/31/05),
1467 is that SHA-256 is a good choice for the time being, but
1468 that research should continue, and other alternatives may
1469 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001470
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001471- Added a subset of Fredrik Lundh's ElementTree package. Available

1513
Georg Brandl532efab2005-08-24 22:34:21 +00001514- Patch #848017: Make Cookie more RFC-compliant. Use CRLF as default output
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001515 separator and do not output trailing semicolon.
Georg Brandl532efab2005-08-24 22:34:21 +00001516
Georg Brandlb9256022005-08-24 18:46:39 +00001517- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
1518 ContentTooShortException, when the actually downloaded size does not
1519 match the Content-Length header.
1520

1524 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001525 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001526

1542 parameter, but uses the usual "kwargs=None".
1543
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001544- textwrap now processes text chunks at O(n) speed instead of O(n**2).

1548 to W3C name (404 -> 'Not Found'). RFE #1216944.
1549
Georg Brandl9e43acf2005-07-04 17:16:07 +00001550- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1551 as this can cause problems with apps closing all file descriptors.

1562
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001563- The tokenize module now detects and reports indentation errors.
1564 Bug #1224621.
1565
Raymond Hettinger68c04532005-06-10 11:05:19 +00001566- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001567 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001568 the generate_tokens() function now accepts a callable argument that
1569 terminates by raising StopIteration.
1570
Georg Brandl9166e1a2005-06-04 09:20:03 +00001571- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1575
Skip Montanaro174dd222005-05-14 20:54:16 +00001576- Patch #1120353: The xmlrpclib module provides better, more transparent,
1577 support for datetime.{datetime,date,time} objects. With use_datetime set
1578 to True, applications shouldn't have to fiddle with the DateTime wrapper
1579 class at all.
1580
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001581- distutils.commands.upload was added to support uploading distribution

1583
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001584- distutils.commands.register now encodes the data as UTF-8 before posting
1585 them to PyPI.
1586
Raymond Hettinger267b8682005-03-27 10:47:39 +00001587- decimal operator and comparison methods now return NotImplemented
1588 instead of raising a TypeError when interacting with other types. This
1589 allows other classes to implement __radd__ style methods and have them
1590 work as expected.
1591
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001592- Bug #1163325: Decimal infinities failed to hash. Attempting to
1593 hash a NaN raised an InvalidOperation instead of a TypeError.
1594
Tim Petersecc6e6a2005-07-10 22:30:55 +00001595- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001596 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1597

Martin v. Löwisa4dac402005-03-03 11:39:45 +00001607 profile.py if available.
1608
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001609- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1610

1619
Martin v. Löwisdf241532005-03-03 08:17:42 +00001620- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
1621

1629
Guido van Rossumd0641422005-02-03 15:01:24 +00001630- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1631 disables recursive traversal through instance attributes, which can
1632 be exploited in various ways.
1633
Tim Peterse3547fd2005-12-16 23:13:57 +00001634- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001635 flags on the HTTP listening socket.
1636
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001637- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1638 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1639
Tim Peterse3547fd2005-12-16 23:13:57 +00001640- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001641 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1642
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001643- Bug #1110478: Revert os.environ.update to do putenv again.

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001645- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1646
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001647- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1648
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001649- Enhancements to the csv module:
1650
1651 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001652 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001653 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001654 + Dialect parameter parsing has been re-implemented to improve error
1655 reporting.
1656 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1657 dictates.
1658 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001659 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001660 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001661 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1662 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001663 + reader now allows \r characters to be quoted (previously it only allowed
1664 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001665 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001666 + Dialect classes passed to the module are no longer instantiated by
1667 the module before being parsed (the former validation scheme required
1668 this, but the mechanism was unreliable).
1669 + The dialect registry now contains instances of the internal
1670 C-coded dialect type, rather than references to python objects.
1671 + the internal c-coded dialect type is now immutable.
1672 + register_dialect now accepts the same keyword dialect specifications
1673 as the reader and writer, allowing the user to register dialects
1674 without first creating a dialect class.
1675 + a configurable limit to the size of parsed fields has been added -
1676 previously, an unmatched quote character could result in the entire
1677 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001678 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001679 the parser field size limit (returning the former limit). The initial
1680 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001681 + A line_num attribute has been added to the reader object, which tracks
1682 the number of lines read from the source iterator. This is not
1683 the same as the number of records returned, as records can span
1684 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001685 + reader and writer objects were not being registered with the cyclic-GC.
1686 This has been fixed.
1687
Brett Cannone6539c42005-01-08 02:43:53 +00001688- _DummyThread objects in the threading module now delete self.__block that is
1689 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1690 lock primitives tend to be limited in number and thus should not be wasted on
1691 a _DummyThread object. Fixes bug #1089632.
1692
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001693- The imghdr module now detects Exif files.
1694
Raymond Hettinger6065d322004-12-20 23:51:53 +00001695- StringIO.truncate() now correctly adjusts the size attribute.
1696 (Bug #951915).
1697
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001698- locale.py now uses an updated locale alias table (built using
1699 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1700 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001701 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001702
Raymond Hettinger3557f422004-12-07 12:02:02 +00001703- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1704
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001705- the pickle module no longer accepts the deprecated None option in the
1706 args tuple returned by __reduce__().
1707
Brett Cannon84667c02004-12-07 03:25:18 +00001708- optparse now optionally imports gettext. This allows its use in setup.py.
1709
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001710- the pickle module no longer uses the deprecated bin parameter.
1711
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001712- the shelve module no longer uses the deprecated binary parameter.
1713
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001714- the pstats module no longer uses the deprecated ignore() method.
1715
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001716- the filecmp module no longer uses the deprecated use_statcache argument.
1717
Raymond Hettinger664347b2004-12-04 21:21:53 +00001718- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1719 extended or overridden by subclasses. Formerly, the subclassed method would
1720 be ignored by the rest of the module. (Bug #1078905).
1721
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001722- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001723 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001724
Walter Dörwald36733692004-12-22 12:50:50 +00001725- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1726 once when a size argument is given. This prevents a buffer overflow in the
1727 tokenizer with very long source lines.
1728
Barry Warsaw538561e2006-01-01 21:48:54 +00001729- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1730 immediately after creating the object, without any intervening
1731 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001732
Skip Montanaro05885812005-01-16 20:48:27 +00001733- The reconvert.quote function can now emit triple-quoted strings. The
1734 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001735
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001736- ``UserString.MutableString`` now supports negative indices in
1737 ``__setitem__`` and ``__delitem__``
1738
Greg Ward40407942005-03-05 02:53:17 +00001739- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1740 correctly.
1741
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001742- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1743 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1744 character even if the user has passed a size parameter to get a proper
1745 line ending. Remove the special handling of a "\r\n" that has been split
1746 between two lines.
1747
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001748- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1749 about illegal code points. The codec now supports PEP 293 style error
1750 handlers.
1751
Walter Dörwald78a78b02005-09-01 12:04:29 +00001752- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001753 from the input stream, so that the output is a byte string in the correct
1754 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001755
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001756- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1757 considering it exactly like a '*'.
1758
Walter Dörwald007f8df2005-10-09 19:42:27 +00001759- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1760 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001761
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001762- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1763
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001764- Patch #1413711: Certain patterns of differences were making difflib
1765 touch the recursion limit.
1766
Walter Dörwald58917a62006-03-31 15:26:22 +00001767- Bug #947906: An object oriented interface has been added to the calendar
1768 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001769 called as a script (e.g. via ``python -mcalendar``). Localized month and
1770 weekday names can be ouput (even if an exotic encoding is used) using
1771 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001773Build
1774-----
1775
Neal Norwitz602d3392006-03-31 08:21:40 +00001776- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1777 by using -mieee gcc option.
1778

1780
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001781- Build support for Win64-AMD64 was added.
1782
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001783- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1784
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001785- Patch #881820: look for openpty and forkpty also in libbsd.
1786
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001787- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1788 The zlib module is now builtin on Windows.
1789
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001790- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1791
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001792- Bug #1189330: configure did not correctly determine the necessary
1793 value of LINKCC if python was built with GCC 4.0.
1794
Trent Mick8321b422005-07-26 02:29:21 +00001795- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1796 vulnerability in zlib 1.2.1 and 1.2.2.
1797
Brett Cannon08cd5982005-04-24 22:26:38 +00001798- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1799 flags that change binary compatibility. Changes were also made to
1800 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001801 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001802
Bob Ippolitoed233462005-03-29 13:47:59 +00001803- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1804 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1805 no longer exists). This configure patch makes things right.
1806
Martin v. Löwise2713be2005-03-08 15:03:08 +00001807- Bug #1158607: Build with --disable-unicode again.
1808
Brett Cannon46d96232005-02-16 00:07:19 +00001809- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1810 defined. Discovered as a result of not being able to build on OS X.
1811
Brett Cannon516592f2004-12-07 00:42:59 +00001812- setup.py now uses the directories specified in LDFLAGS using the -L option
1813 and in CPPFLAGS using the -I option for adding library and include
1814 directories, respectively, for compiling extension modules against. This has
1815 led to the core being compiled using the values in CPPFLAGS. It also removes
1816 the need for the special-casing of both DarwinPorts and Fink for darwin since
1817 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1818 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1819 Fink, ``-I/opt/local/include`` for DarwinPorts).
1820
Brett Cannon43802422005-02-10 20:48:03 +00001821- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1822 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1823 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1824 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001826C API
1827-----
1828
Tim Petersc9d78aa2006-03-26 23:27:58 +00001829- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1830 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1831 is obtained via the ``PyObject_`` family, it must be released via the
1832 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1833 always been officially true, but when Python's small-object allocator was
1834 introduced, an attempt was made to cater to a few extension modules
1835 discovered at the time that obtained memory via ``PyObject_New`` but
1836 released it via ``PyMem_DEL``. It's years later, and if such code still
1837 exists it will fail now (probably with segfaults, but calling wrong
1838 low-level memory management functions can yield many symptoms).
1839
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001840- Added a C API for set and frozenset objects.
1841
Raymond Hettinger66517482004-12-03 11:45:13 +00001842- Removed PyRange_New().
1843
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001844- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1845 mapping argument now. This string is used as a mapping table. Byte values
1846 greater than the length of the string and 0xFFFE are treated as undefined
1847 mappings.

1852
Martin v. Löwis4d394df2005-01-23 09:19:22 +00001853- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001854
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001855- Patch #1276356: New resource "urlfetch" is implemented. This enables
1856 even impatient people to run tests that require remote files.
