Fred Drake53912162006-07-29 13:22:49 +00007What's New in Python 2.5 beta 3?
8================================
Neal Norwitza1f10902006-07-12 07:28:29 +00009
10*Release date: XX-AUG-2006*
11
12Core and builtins
13-----------------
14
Neal Norwitzf71ec5a2006-07-30 06:57:04 +000015- Bug #1515471: string.replace() accepts character buffers again.
16
Neal Norwitz07aadb12006-07-30 06:55:48 +000017- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
18 This provides the proper warning for struct.pack().
19 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
20
Neal Norwitz0d62a062006-07-30 06:53:31 +000021- Patch #1531113: Fix augmented assignment with yield expressions.
22 Also fix a SystemError when trying to assign to yield expressions.
23
Phillip J. Ebyf7575d02006-07-28 21:12:07 +000024- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
25 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
26 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
27 excessive filesystem operations during imports.
28
Tim Petersbc24eee2006-07-27 01:14:53 +000029- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
30 operations on signed longs that are formally undefined by C.
31 Unfortunately, at least one compiler now cares about that, so complicated
32 the code to make that compiler happy again.
33
Martin v. Löwis982e9fe2006-07-24 12:54:17 +000034- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
35
Martin v. Löwisd22968a2006-07-24 11:54:53 +000036- Patch #1232023: Stop including current directory in search
37 path on Windows.
38
Neal Norwitze1fdb322006-07-21 05:32:28 +000039- Fix some potential crashes found with failmalloc.
40
Neal Norwitze7563102006-07-17 01:00:16 +000041- Fix warnings reported by Klocwork's static analysis tool.
42
Neal Norwitz84be93b2006-07-16 01:50:38 +000043- Bug #1512814, Fix incorrect lineno's when code within a function
44 had more than 255 blank lines.
45
Georg Brandl9dceedb2006-07-12 15:31:17 +000046- Patch #1521179: Python now accepts the standard options ``--help`` and
47 ``--version`` as well as ``/?`` on Windows.
48
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +000049- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +000050 again. Fixing this problem required changing the .pyc magic number.
51 This means that .pyc files generated before 2.5c1 will be regenerated.
52
Tim Peters112aad32006-07-19 00:03:19 +000053- Bug #1524317: Compiling Python ``--without-threads`` failed.
54 The Python core compiles again then, and, in a build without threads, the
55 new ``sys._current_frames()`` returns a dictionary with one entry,
56 mapping the faux "thread id" 0 to the current frame.
57
Ronald Oussoren3075e162006-07-25 20:28:55 +000058- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +000059
Ronald Oussoren3075e162006-07-25 20:28:55 +000060
Neal Norwitza1f10902006-07-12 07:28:29 +000061Library
62-------
63
Georg Brandl07fec3a2006-08-01 18:49:24 +000064- os.urandom no longer masks unrelated exceptions like SystemExit or
65 KeyboardInterrupt.
66
Martin v. Löwis4e678382006-07-30 13:00:31 +000067- Bug #1525866: Don't copy directory stat times in
68 shutil.copytree on Windows
69
Georg Brandle34ac7c2006-07-30 11:07:23 +000070- Bug #1002398: The documentation for os.path.sameopenfile now correctly
71 refers to file descriptors, not file objects.
72
Fred Drakefbdeaad2006-07-29 16:56:15 +000073- Rename of the xml package to xmlcore, and the import hackery done to
74 make it appear at both names, has been removed. Bug #1511497,
75 #1513611, and probably others.
76
Georg Brandledd9b0d2006-07-29 09:33:26 +000077- Bug #1441397: The compiler module now recognizes module and function
78 docstrings correctly as it did in Python 2.4.
79
Tim Peters6f681472006-07-27 23:44:37 +000080- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
81 lost that tests are sorted by name before being run. This rarely
82 matters for well-written tests, but can create baffling symptoms if
83 side effects from one test to the next affect outcomes. ``DocTestFinder``
84 has been changed to sort the list of tests it returns.
85
Martin v. Löwis1f30c372006-07-30 13:14:05 +000086- The distutils version has been changed to 2.5.0, and are now kept
87 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +000088
Martin v. Löwis9298eff2006-07-26 12:12:56 +000089- Bug #978833: Really close underlying socket in _socketobject.close.
90
Georg Brandl0619a322006-07-26 07:40:17 +000091- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
92 with title().
93
Georg Brandlcf0c1722006-07-26 07:23:32 +000094- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
95 to recursive calls and call it with the failing package name.
96
Martin v. Löwis0b483032006-07-25 09:53:12 +000097- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
98
Georg Brandlc13c34c2006-07-24 14:09:56 +000099- Patch #1515343: Fix printing of deprecated string exceptions with a
100 value in the traceback module.
101
Greg Ward48fae7a2006-07-23 16:05:51 +0000102- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
103
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000104- Patch #1524429: Use repr() instead of backticks in Tkinter again.
105
Brett Cannoncaebe222006-07-18 04:41:36 +0000106- Bug #1520914: Change time.strftime() to accept a zero for any position in its
107 argument tuple. For arguments where zero is illegal, the value is forced to
108 the minimum value that is correct. This is to support an undocumented but
109 common way people used to fill in inconsequential information in the time
110 tuple pre-2.4.
111
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000112- Patch #1220874: Update the binhex module for Mach-O.
113
Barry Warsawb110bad2006-07-21 14:51:07 +0000114- The email package has improved RFC 2231 support, specifically for
115 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
116 (name*0=<blah>) parameter continuations. This may change the types of
117 values returned from email.message.Message.get_param() and friends.
118 Specifically in some cases where non-encoded continuations were used,
119 get_param() used to return a 3-tuple of (None, None, string) whereas now it
120 will just return the string (since non-encoded continuations don't have
121 charset and language parts).
122
123 Also, whereas % values were decoded in all parameter continuations, they are
124 now only decoded in encoded parameter parts.
125
Ronald Oussoren3075e162006-07-25 20:28:55 +0000126- Bug #1517990: IDLE keybindings on MacOS X now work correctly
127
128- Bug #1517996: IDLE now longer shows the default Tk menu when a
129 path browser, class browser or debugger is the frontmost window on MacOS X
130
Barry Warsaw00decd72006-07-27 23:43:15 +0000131- Patch #1520294: Support for getset and member descriptors in types.py,
132 inspect.py, and pydoc.py. Specifically, this allows for querying the type
133 of an object against these built-in types and more importantly, for getting
134 their docstrings printed in the interactive interpreter's help() function.
135
Ronald Oussoren3075e162006-07-25 20:28:55 +0000136
Neal Norwitza1f10902006-07-12 07:28:29 +0000137Extension Modules
138-----------------
139
Thomas Heller1393d6a2006-07-28 21:43:20 +0000140- Patch #1529514: The _ctypes extension is now compiled on more
141 openbsd target platforms.
142
Tim Peters9cab5932006-07-28 00:30:00 +0000143- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
144 a memory leak, affecting pickles and deep copies.
145
Tim Petersbc24eee2006-07-27 01:14:53 +0000146- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000147 Paul Eggert.
148
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000149- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
150
Thomas Hellerce049a02006-07-14 17:51:14 +0000151- Patch #1521817: Index range checking on ctypes arrays containing
152 exactly one element enabled again. This allows iterating over these
153 arrays, without the need to check the array size before.
154
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000155- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000156 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000157 /dev/null in certain cases; this is now fixed.
158
Thomas Heller47d7a062006-07-12 08:43:47 +0000159- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
160 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000161
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000162- Because of a misspelled preprocessor symbol, ctypes was always
163 compiled without thread support; this is now fixed.
164
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000165- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
166 methods now allow their database parameter to be None as the
167 sleepycat API allows.
168
Matt Flemingec926502006-07-28 11:27:27 +0000169- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
170 bluetooth API compared with Linux and FreeBSD.
171
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000172Tests
173-----
174
175- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
176 how long the test file should take to play. Now accepts taking 2.93 secs
177 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
178
Georg Brandl4793aa32006-07-28 18:31:39 +0000179- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
180 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
181 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000182
Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000183Build
184-----
185
186- Bug #1439538: Drop usage of test -e in configure as it is not portable.
187
Ronald Oussoren26cad082006-08-01 21:00:57 +0000188Mac
189---
190
191- PythonLauncher now works correctly when the path to the script contains
192 characters that are treated specially by the shell (such as quotes).
193
194- Bug #1527397: PythonLauncher now launches scripts with the working directory
195 set to the directory that contains the script instead of the user home
196 directory. That latter was an implementation accident and not what users
197 expect.
198

Georg Brandlad29e632006-06-21 17:45:17 +0000200What's New in Python 2.5 beta 2?
201================================
202
Anthony Baxter70e8e872006-07-10 07:41:04 +0000203*Release date: 11-JUL-2006*
Georg Brandlad29e632006-06-21 17:45:17 +0000204
205Core and builtins
206-----------------
207
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000208- Bug #1441486: The literal representation of -(sys.maxint - 1)
209 again evaluates to a int object, not a long.
210
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000211- Bug #1501934: The scope of global variables that are locally assigned
212 using augmented assignment is now correctly determined.
213
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000214- Bug #927248: Recursive method-wrapper objects can now safely
215 be released.
216
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000217- Bug #1417699: Reject locale-specific decimal point in float()
218 and atof().
219
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000220- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
221 omit a default "error" argument for NULL pointer. This allows
222 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000223
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000224- Bug #1519018: 'as' is now validated properly in import statements.
225
Neal Norwitz28746ab2006-07-09 22:14:42 +0000226- On 64 bit systems, int literals that use less than 64 bits are
227 now ints rather than longs.
228
Neal Norwitzed657552006-07-10 00:04:44 +0000229- Bug #1512814, Fix incorrect lineno's when code at module scope
230 started after line 256.
231
Tim Peters32a83612006-07-10 21:08:24 +0000232- New function ``sys._current_frames()`` returns a dict mapping thread
233 id to topmost thread stack frame. This is for expert use, and is
234 especially useful for debugging application deadlocks. The functionality
235 was previously available in Fazal Majid's ``threadframe`` extension
236 module, but it wasn't possible to do this in a wholly threadsafe way from
237 an extension.
238
Georg Brandlad29e632006-06-21 17:45:17 +0000239Library
240-------
241
Martin v. Löwis77621582006-07-30 13:27:31 +0000242- Bug #1257728: Mention Cygwin in distutils error message about a missing
243 VS 2003.
244

Martin v. Löwis8d656812006-07-10 07:23:48 +0000248 environment variable to be set in order to the SDK environment
249 for finding the compiler, include files, etc.
250

254
Thomas Woutersadd19112006-07-05 11:03:49 +0000255- string.Template() now correctly handles tuple-values. Previously,
256 multi-value tuples would raise an exception and single-value tuples would
257 be treated as the value they contain, instead.
258
Martin v. Löwisede77f52006-07-03 13:01:35 +0000259- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

266 degrees and radians.
267
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000268- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000269 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000270
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000271- Bug #1514703: Only setup canvas window in turtle when the canvas
272 is created.
273
Martin v. Löwis7596e832006-07-01 15:33:37 +0000274- Bug #1513223: .close() of a _socketobj now releases the underlying
275 socket again, which then gets closed as it becomes unreferenced.
276
Fred Drake10497c82006-06-29 02:57:48 +0000277- Bug #1504333: Make sgmllib support angle brackets in quoted

281 sgmllib ('[' and ']' were not accepted).
282
Georg Brandl1be63af2006-06-28 20:23:25 +0000283- Fix a bug in the turtle module's end_fill function.
284
Brett Cannon53ab5b72006-06-22 16:49:14 +0000285- Bug #1510580: The 'warnings' module improperly required that a Warning
286 category be either a types.ClassType and a subclass of Warning. The proper
287 check is just that it is a subclass with Warning as the documentation states.
288
Georg Brandlad29e632006-06-21 17:45:17 +0000289- The compiler module now correctly compiles the new try-except-finally
290 statement (bug #1509132).
291
Neal Norwitz60373cd2006-06-22 06:30:50 +0000292- The wsgiref package is now installed properly on Unix.
293
Vinay Sajip28e57612006-07-01 10:45:20 +0000294- A bug was fixed in logging.config.fileConfig() which caused a crash on
295 shutdown when fileConfig() was called multiple times.
296
Gerhard Häring762fbd32006-07-02 17:48:30 +0000297- The sqlite3 module did cut off data from the SQLite database at the first
298 null character before sending it to a custom converter. This has been fixed
299 now.
300
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000301Extension Modules
302-----------------
303
Tim Peters112aad32006-07-19 00:03:19 +0000304- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
305 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
306 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000307
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000308- Assigning None to pointer type fields in ctypes structures possible
309 overwrote the wrong fields, this is fixed now.
310
311- Fixed a segfault in _ctypes when ctypes.wintypes were imported
312 on non-Windows platforms.
313
314- Bug #1518190: The ctypes.c_void_p constructor now accepts any
315 integer or long, without range checking.
316
317- Patch #1517790: It is now possible to use custom objects in the ctypes
318 foreign function argtypes sequence as long as they provide a from_param
319 method, no longer is it required that the object is a ctypes type.
320
321- The '_ctypes' extension module now works when Python is configured
322 with the --without-threads option.
323
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000324- Bug #1513646: os.access on Windows now correctly determines write
325 access, again.
326
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000327- Bug #1512695: cPickle.loads could crash if it was interrupted with
328 a KeyboardInterrupt.
329
Neal Norwitza12aa882006-07-06 06:45:08 +0000330- Bug #1296433: parsing XML with a non-default encoding and
331 a CharacterDataHandler could crash the interpreter in pyexpat.
332
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000333- Patch #1516912: improve Modules support for OpenVMS.

336-----
337
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000338- Automate Windows build process for the Win64 SSL module.
339
Tim Peters32a83612006-07-10 21:08:24 +0000340- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000341 Previously, the slight difference could cause compilation errors of the
342 'zlib' module on systems with more than one version of zlib.
343
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000344- The MSI compileall step was fixed to also support a TARGETDIR
345 with spaces in it.
346
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000347- Bug #1517388: sqlite3.dll is now installed on Windows independent
348 of Tcl/Tk.
349
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000350- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000351 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +0000353Tests
354-----
355
356- Call os.waitpid() at the end of tests that spawn child processes in order
357 to minimize resources (zombies).
358
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000359Documentation

361
Nick Coghlan2d792252006-07-06 13:47:18 +0000362- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
363 documentation for the warnings module.
364
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000365- Patch #1509163: MS Toolkit Compiler no longer available.
366
Neal Norwitz56640df2006-07-10 02:36:41 +0000367- Patch #1504046: Add documentation for xml.etree.

Nick Coghlanc649ec52006-05-29 12:43:05 +0000369What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +0000370================================
Anthony Baxter51bcb682006-04-05 14:51:42 +0000371
Anthony Baxterd1136802006-06-19 12:04:15 +0000372*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000373
374Core and builtins
375-----------------
376
Georg Brandla56b9152006-06-19 06:35:54 +0000377- Patch #1507676: Error messages returned by invalid abstract object operations
378 (such as iterating over an integer) have been improved and now include the
379 type of the offending object to help with debugging.
380
Brett Cannonea3912b2006-06-13 21:46:41 +0000381- Bug #992017: A classic class that defined a __coerce__() method that returned
382 its arguments swapped would infinitely recurse and segfault the interpreter.
383
Neal Norwitz909eb122006-06-12 02:13:21 +0000384- Fix the socket tests so they can be run concurrently.
385
Neal Norwitzb9845e72006-06-12 02:11:18 +0000386- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000387 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000388
Brett Cannon22565aa2006-06-09 22:31:23 +0000389- Bug #532646: object.__call__() will continue looking for the __call__
390 attribute on objects until one without one is found. This leads to recursion
391 when you take a class and set its __call__ attribute to an instance of the
392 class. Originally fixed for classic classes, but this fix is for new-style.
393 Removes the infinite_rec_3 crasher.
394
Georg Brandl24250812006-06-09 18:45:48 +0000395- The string and unicode methods startswith() and endswith() now accept
396 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
397
Brett Cannonde3b0522006-06-08 17:00:45 +0000398- Buffer objects, at the C level, never used the char buffer
399 implementation even when the char buffer for the wrapped object was
400 explicitly requested (originally returned the read or write buffer).
401 Now a TypeError is raised if the char buffer is not present but is
402 requested.
403
Georg Brandlddbaa662006-06-04 21:56:52 +0000404- Patch #1346214: Statements like "if 0: suite" are now again optimized
405 away like they were in Python 2.4.
406
Georg Brandlb7c8f542006-05-27 12:30:25 +0000407- Builtin exceptions are now full-blown new-style classes instead of
408 instances pretending to be classes, which speeds up exception handling
409 by about 80% in comparison to 2.5a2.
410
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000411- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
412 Unicode 4.1.
413
Georg Brandlf4ef1162006-05-26 18:03:31 +0000414- Patch #921466: sys.path_importer_cache is now used to cache valid and
415 invalid file paths for the built-in import machinery which leads to
416 fewer open calls on startup.
417
Tim Peters696cf432006-05-24 21:10:40 +0000418- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
419 of-2 bases. The largest speedup is for inputs with about 1000 decimal
420 digits. Conversion from non-power-of-2 bases remains quadratic-time in
421 the number of input digits (it was and remains linear-time for bases
422 2, 4, 8, 16 and 32).
423
Tim Petersb713ec22006-05-23 18:45:30 +0000424- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
425 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
426 an integer close to ``sys.maxint``. This was repaired by patch
427 #1335972, which also gives a nice speedup.
428
Richard Jonescebbefc2006-05-23 18:28:17 +0000429- Patch #1337051: reduced size of frame objects.
430
431- PyErr_NewException now accepts a tuple of base classes as its
432 "base" parameter.
433
Richard Jones7c88dcc2006-05-23 10:37:38 +0000434- Patch #876206: function call speedup by retaining allocated frame
435 objects.
436
Georg Brandl7b90e162006-05-18 07:01:27 +0000437- Bug #1462152: file() now checks more thoroughly for invalid mode
438 strings and removes a possible "U" before passing the mode to the
439 C library function.
440
Neal Norwitz1004a532006-05-15 07:17:23 +0000441- Patch #1488312, Fix memory alignment problem on SPARC in unicode
442
Neal Norwitz373f0a72006-05-15 07:04:36 +0000443- Bug #1487966: Fix SystemError with conditional expression in assignment
444
Martin v. Löwis879768d2006-05-11 13:28:43 +0000445- WindowsError now has two error code attributes: errno, which carries
446 the error values from errno.h, and winerror, which carries the error
447 values from winerror.h. Previous versions put the winerror.h values
448 (from GetLastError()) into the errno attribute.
449
Martin v. Löwis77736712006-05-04 05:51:03 +0000450- Patch #1475845: Raise IndentationError for unexpected indent.
451
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000452- Patch #1479181: split open() and file() from being aliases for each other.
453
Tim Peters44bd9862006-06-01 13:49:23 +0000454- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
455 methods were always silently ignored by dictionaries when comparing keys.
456 They are now passed through (except when using the C API function
457 ``PyDict_GetItem()``, whose semantics did not change).
458
459- Bug #1456209: In some obscure cases it was possible for a class with a
460 custom ``__eq__()`` method to confuse dict internals when class instances
461 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
462 No, you don't have any code that did this ;-)

468
469- Patch #1462338: Upgrade pyexpat to expat 2.0.0
470
Brett Cannon6ee7d012006-06-08 16:23:04 +0000471- Change binascii.hexlify to accept a read-only buffer instead of only a char
472 buffer and actually follow its documentation.
473
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000474- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
475
Nick Coghlanc649ec52006-05-29 12:43:05 +0000476- Patch #1478788 (modified version): The functional extension module has
477 been renamed to _functools and a functools Python wrapper module added.
478 This provides a home for additional function related utilities that are
479 not specifically about functional programming. See PEP 309.
480
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000481- Patch #1493701: performance enhancements for struct module.
482
Georg Brandl378d5922006-05-17 14:26:50 +0000483- Patch #1490224: time.altzone is now set correctly on Cygwin.
484
Georg Brandl8d3342b2006-05-16 07:38:27 +0000485- Patch #1435422: zlib's compress and decompress objects now have a
486 copy() method.
487
Andrew MacIntyre92913322006-06-13 15:04:24 +0000488- Patch #1454481: thread stack size is now tunable at runtime for thread
489 enabled builds on Windows and systems with Posix threads support.
490
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000491- On Win32, os.listdir now supports arbitrarily-long Unicode path names
492 (up to the system limit of 32K characters).
493
494- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
495 As a result, these functions now raise WindowsError instead of OSError.
496
Tim Peters7a822da2006-05-25 21:50:17 +0000497- ``time.clock()`` on Win64 should use the high-performance Windows
498 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
499 Windows platforms).
500
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000501- Calling Tk_Init twice is refused if the first call failed as that
502 may deadlock.
503
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000504- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
505 accept it without potentially using an uninitialized pointer.
506
507- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
508 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
509 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000510
Gregory P. Smith372b5832006-06-05 18:48:21 +0000511- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000512 [pybsddb project SF patch number 1466734]
513
Gregory P. Smith372b5832006-06-05 18:48:21 +0000514- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
515 parameter is supplied. [SF pybsddb bug #1477863]
516
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000517- bsddb: the __len__ method of a DB object has been fixed to return correct
518 results. It could previously incorrectly return 0 in some cases.
519 Fixes SF bug 1493322 (pybsddb bug 1184012).
520
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000521- bsddb: the bsddb.dbtables Modify method now raises the proper error and
522 aborts the db transaction safely when a modifier callback fails.
523 Fixes SF python patch/bug #1408584.
524
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000525- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000526 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000527 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
528 database calls that would previously deadlock. [SF python bug #775414]
529
Vinay Sajip28e57612006-07-01 10:45:20 +0000530- Patch #1446489: add support for the ZIP64 extensions to zipfile.

Walter Dörwald4994d952006-06-19 08:07:50 +0000532- Patch #1506645: add Python wrappers for the curses functions
533 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000534
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000535Library
536-------
537
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000538- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
539 functions.
540
Martin v. Löwis3798da02006-06-17 18:44:27 +0000541- Patch #812986: Update turtle output even if not tracing.
542
Vinay Sajip28e57612006-07-01 10:45:20 +0000543- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000544 Tkinter.BaseWidget.
545
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000546- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
547
Martin v. Löwis337487e2006-06-17 09:15:14 +0000548- Patch #763580: Add name and value arguments to Tkinter variable
549 classes.
550
Georg Brandl83cc0d02006-06-14 08:50:03 +0000551- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
552 mime.types file for determining MIME types.
553
Georg Brandl2605ca82006-06-14 06:08:31 +0000554- Bug #1339007: Shelf objects now don't raise an exception in their
555 __del__ method when initialization failed.
556
Martin v. Löwisd8251432006-06-14 05:21:04 +0000557- Patch #1455898: The MBCS codec now supports the incremental mode for
558 double-byte encodings.
559
Tim Peters43898b42006-06-14 04:09:25 +0000560- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
561 guarantee that adjacent triples in the return list always describe
562 non-adjacent blocks. Previously, a pair of matching blocks could end
563 up being described by multiple adjacent triples that formed a partition
564 of the matching pair.
565
Greg Ward0e0c9f42006-06-11 16:24:11 +0000566- Bug #1498146: fix optparse to handle Unicode strings in option help,
567 description, and epilog.
568
Greg Wardd1c797e2006-06-11 14:42:41 +0000569- Bug #1366250: minor optparse documentation error.
570
Greg Ward7f547402006-06-11 00:40:49 +0000571- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
572 clarify docs.
573
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000574- The wsgiref package has been added to the standard library.
575
Nick Coghlan676725d2006-06-08 13:54:49 +0000576- The functions update_wrapper() and wraps() have been added to the functools
577 module. These make it easier to copy relevant metadata from the original
578 function when writing wrapper functions.
579
Tim Petersd6a9eef2006-06-05 01:48:21 +0000580- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
581 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000582
Martin v. Löwis3f767792006-06-04 19:36:28 +0000583- Patch #1359618: Speed up charmap encoder by using a trie structure
584 for lookup.
585
Tim Petersd609b1a2006-06-02 23:22:51 +0000586- The functions in the ``pprint`` module now sort dictionaries by key
587 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
588 if and only if its display required more than one line, although that
589 wasn't documented. The new behavior increases predictability; e.g.,
590 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
591
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000592- Patch #1497027: try HTTP digest auth before basic auth in urllib2
593 (thanks for J. J. Lee).
594
Georg Brandl2b330372006-05-28 20:23:12 +0000595- Patch #1496206: improve urllib2 handling of passwords with respect to
596 default HTTP and HTTPS ports.
597
George Yoshidaf3c65de2006-05-28 16:39:09 +0000598- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
599
Bob Ippolito7298f272006-05-23 18:43:47 +0000600- Patch #1281707: speed up gzip.readline.
601
Georg Brandlb89316f2006-05-17 15:51:16 +0000602- Patch #1180296: Two new functions were added to the locale module:
603 format_string() to get the effect of "format % items" but locale-aware,
604 and currency() to format a monetary number with currency sign.
605
Georg Brandle3a25832006-05-17 14:56:04 +0000606- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
607 and several features added, such as speed and geometry control.
608
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000609- Patch #1488881: add support for external file objects in bz2 compressed
610 tarfiles.
611
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000612- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
613 stdout arguments, making it possible to redirect input and output

618 GNU LONGNAME extension.
619
620- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
621 new flag when ``name`` is already the name of an option flag.

661
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000662What's New in Python 2.5 alpha 2?
663=================================
664
665*Release date: 27-APR-2006*
666
667Core and builtins
668-----------------
669
Thomas Heller1b046642006-04-18 18:51:06 +0000670- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
671 by converting these apis from macros into exported functions again:
672
673 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
674 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
675 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
676 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
677 PyRun_String Py_CompileString
678
Martin v. Löwis45294a92006-04-18 06:24:08 +0000679- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
680
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000681- All uses of PyStructSequence_InitType have been changed to initialize
682 the type objects only once, even if the interpreter is initialized
683 multiple times.
684
Neal Norwitz61546162006-04-14 05:20:28 +0000685- Bug #1454485, array.array('u') could crash the interpreter. This was
686 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
687 to unicode when it didn't make sense. 'u#' now requires a unicode string.
688
689- Py_UNICODE is unsigned. It was always documented as unsigned, but
690 due to a bug had a signed value in previous versions.
691
Tim Peters3a5e8b12006-04-11 01:44:07 +0000692- Patch #837242: ``id()`` of any Python object always gives a positive
693 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
694 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000695 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000696 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000697
Tim Peters3a5e8b12006-04-11 01:44:07 +0000698 def __hash__(self):
699 return id(self) # WRONG
700
701 because a hash result must be a (short) Python int but it was always
702 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000703 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000704 was always usable as a hash value before this patch. That's no longer
705 necessarily so.
706
707- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000708 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000709 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000710 #1454844)
711
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000712- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
713 involving generators that have paused outside of any ``try`` or ``with``
714 blocks. (In 2.5a1, a paused generator that was part of a reference
715 cycle could not be garbage collected, regardless of whether it was
716 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000718Extension Modules

Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000721- Patch #1191065: Fix preprocessor problems on systems where recvfrom
722 is a macro.
723
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000724- Bug #1467952: os.listdir() now correctly raises an error if readdir()
725 fails with an error condition.
726
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000727- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
728
729- Bug #1117761: bsddb.*open() no longer raises an exception when using
730 the cachesize parameter.
731
732- Bug #1149413: bsddb.*open() no longer raises an exception when using
733 a temporary db (file=None) with the 'n' flag to truncate on open.
734
735- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
736 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000737
Armin Rigoa9017c32006-04-19 11:50:27 +0000738- Patch #1062014: AF_UNIX sockets under Linux have a special
739 abstract namespace that is now fully supported.
740
Anthony Baxter51bcb682006-04-05 14:51:42 +0000741Library
742-------
743
Peter Astrand7d1d4362006-07-14 14:04:45 +0000744- Bug #1223937: subprocess.CalledProcessError reports the exit status
745 of the process using the returncode attribute, instead of
746 abusing errno.
747
Tim Peters711bf302006-04-25 03:31:36 +0000748- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
749 a doctest to be skipped (the code is not run, and the expected output
750 or exception is ignored).
751
Nick Coghlanda2268f2006-04-24 04:37:15 +0000752- Fixed contextlib.nested to cope with exceptions being raised and
753 caught inside exit handlers.
754
Greg Wardab05edc2006-04-23 03:47:58 +0000755- Updated optparse module to Optik 1.5.1 (allow numeric constants in
756 hex, octal, or binary; add ``append_const`` action; keep going if
757 gettext cannot be imported; added ``OptionParser.destroy()`` method;
758 added ``epilog`` for better help generation).
759
Tim Peters21fbd572006-04-21 21:18:10 +0000760- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
761 called from a thread spawned as a side effect of importing a module.
762
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000763- The pydoc module now supports documenting packages contained in
764 .zip or .egg files.
765
766- The pkgutil module now has several new utility functions, such
767 as ``walk_packages()`` to support working with packages that are either
768 in the filesystem or zip files.
769
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000770- The mailbox module can now modify and delete messages from
771 mailboxes, in addition to simply reading them. Thanks to Gregory
772 K. Johnson for writing the code, and to the 2005 Google Summer of
773 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000774
Tim Petersc7605f22006-04-17 21:12:33 +0000775- The ``__del__`` method of class ``local`` in module ``_threading_local``
776 returned before accomplishing any of its intended cleanup.
777
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000778- Patch #790710: Add breakpoint command lists in pdb.
779
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000780- Patch #1063914: Add Tkinter.Misc.clipboard_get().
781
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000782- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
783
Anthony Baxtere29002c2006-04-12 12:07:31 +0000784- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
785 Windows. Bug #1469163.
786
Phillip J. Eby47032112006-04-11 01:07:43 +0000787- The warnings, linecache, inspect, traceback, site, and doctest modules
788 were updated to work correctly with modules imported from zipfiles or
789 via other PEP 302 __loader__ objects.
790
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000791- Patch #1467770: Reduce usage of subprocess._active to processes which
792 the application hasn't waited on.
793
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000794- Patch #1462222: Fix Tix.Grid.
795
Neal Norwitza31bf182006-04-09 03:35:43 +0000796- Fix exception when doing glob.glob('anything*/')
797
Skip Montanaro262fb922006-04-21 02:31:07 +0000798- The pstats.Stats class accepts an optional stream keyword argument to
799 direct output to an alternate file-like object.
800

802-----
803
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000804- The Makefile now has a reindent target, which runs reindent.py on
805 the library.
806
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000807- Patch #1470875: Building Python with MS Free Compiler
808
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000809- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000810
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000811- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
812 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000813 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000814 CXX from --with-cxx-main, see description in README.
815
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000816- Patch #1429775: Link extension modules with the shared libpython.
817
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000818- Fixed a libffi build problem on MIPS systems.
819
Tim Peters8931ff12006-05-13 23:28:20 +0000820- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
821 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
822 and "%zu" for unsigned integers of type ``size_t``.
823
Anthony Baxter51bcb682006-04-05 14:51:42 +0000824Tests
825-----
826
Nick Coghlanda2268f2006-04-24 04:37:15 +0000827- test_contextlib now checks contextlib.nested can cope with exceptions
828 being raised and caught inside exit handlers.
829
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000830- test_cmd_line now checks operation of the -m and -c command switches
831
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000832- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
833 it separately and by hand. It also wasn't cleaning up its changes to
834 the current Decimal context.
835
Thomas Woutersabd08882006-04-26 15:53:30 +0000836- regrtest.py now has a -M option to run tests that test the new limits of
837 containers, on 64-bit architectures. Running these tests is only sensible
838 on 64-bit machines with more than two gigabytes of memory. The argument
839 passed is the maximum amount of memory for the tests to use.

848-------------
849
Tim Petersb06d28c2006-05-12 01:57:59 +0000850- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
851
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000852- PEP 343: Added Context Types section to the library reference
853 and attempted to bring other PEP 343 related documentation into
854 line with the implementation and/or python-dev discussions.
855
Tim Peters8dc73d22006-04-24 02:03:16 +0000856- Bug #1337990: clarified that ``doctest`` does not support examples
857 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000860What's New in Python 2.5 alpha 1?
861=================================
862
Anthony Baxterebed3f62006-04-03 15:03:44 +0000863*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000864
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000865Core and builtins
866-----------------
867
Nick Coghlan43832302006-04-23 17:04:07 +0000868- PEP 338: -m command line switch now delegates to runpy.run_module
869 allowing it to support modules in packages and zipfiles
870
Martin v. Löwisc661b882006-04-20 04:54:23 +0000871- On Windows, .DLL is not an accepted file name extension for
872 extension modules anymore; extensions are only found if they
873 end in .PYD.
874
Martin v. Löwisea62d252006-04-03 10:56:49 +0000875- Bug #1421664: sys.stderr.encoding is now set to the same value as
876 sys.stdout.encoding.
877
Neal Norwitz92e212f2006-04-03 04:48:37 +0000878- __import__ accepts keyword arguments.
879
Georg Brandlccadf842006-03-31 18:54:53 +0000880- Patch #1460496: round() now accepts keyword arguments.
881
Anthony Baxter262c00a2006-03-30 10:53:17 +0000882- Fixed bug #1459029 - unicode reprs were double-escaped.
883
Hye-Shik Changd478f342006-03-23 12:32:36 +0000884- Patch #1396919: The system scope threads are reenabled on FreeBSD
885 5.4 and later versions.
886
Neal Norwitze98ccf62006-03-23 05:39:47 +0000887- Bug #1115379: Compiling a Unicode string with an encoding declaration
888 now gives a SyntaxError.
889
Georg Brandlabd1ff82006-03-18 07:59:59 +0000890- Previously, Python code had no easy way to access the contents of a
891 cell object. Now, a ``cell_contents`` attribute has been added
892 (closes patch #1170323).
893
Tim Peterscf79aac2006-03-16 01:14:46 +0000894- Patch #1123430: Python's small-object allocator now returns an arena to
895 the system ``free()`` when all memory within an arena becomes unused
896 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
897 freed. Some applications will see a drop in virtual memory size now,
898 especially long-running applications that, from time to time, temporarily
899 use a large number of small objects. Note that when Python returns an
900 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000901 platform C library will in turn return that memory to the operating system.
902 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000903 appears to be effective at least on Microsoft C and gcc-based systems.
904 Thanks to Evan Jones for hard work and patience.
905
Georg Brandl533ff6f2006-03-08 18:09:27 +0000906- Patch #1434038: property() now uses the getter's docstring if there is
907 no "doc" argument given. This makes it possible to legitimately use
908 property() as a decorator to produce a read-only property.
909
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000910- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
911 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
912 of requiring an int or long in slicing and a few other contexts, enabling
913 other objects (e.g. Numeric Python's integers) to be used as slice indices.
914
Neal Norwitz995acdf2006-03-07 05:01:00 +0000915- Fixed various bugs reported by Coverity's Prevent tool.
916
Brett Cannonbf364092006-03-01 04:25:17 +0000917- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
918 new exception base class, BaseException, which has a new message attribute.
919 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
920 Raising a string exception now raises a DeprecationWarning.
921
Thomas Woutersfb609f42006-02-28 16:37:25 +0000922- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
923 explicitly relative, using 'from .module import name' to mean 'from the same
924 package as this module is in. Imports without dots still default to the
925 old relative-then-absolute, unless 'from __future__ import
926 absolute_import' is used.
927
Brett Cannona7446e32006-02-27 23:39:10 +0000928- Properly check if 'warnings' raises an exception (usually when a filter set
929 to "error" is triggered) when raising a warning for raising string
930 exceptions.
931
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000932- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000933 The name was removed from Include/code.h.
934
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000935- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000936
Guido van Rossum1968ad32006-02-25 22:38:04 +0000937- Patch 1433928:
938 - The copy module now "copies" function objects (as atomic objects).
939 - dict.__getitem__ now looks for a __missing__ hook before raising
940 KeyError.
941
Tim Peters84ef21c2006-02-28 20:39:06 +0000942- PEP 343: with statement implemented. Needs ``from __future__ import
943 with_statement``. Use of 'with' as a variable will generate a warning.
944 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000945 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000946 The following objects have __context__ methods:
947 - The built-in file type.
948 - The thread.LockType type.
949 - The following types defined by the threading module:
950 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
951 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000952
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000953- Fix the encodings package codec search function to only search
954 inside its own package. Fixes problem reported in patch #1433198.
955
956 Note: Codec packages should implement and register their own
957 codec search function. PEP 100 has the details.
958
Tim Peters9ea89d22006-06-04 03:26:02 +0000959- PEP 353: Using ``Py_ssize_t`` as the index type.
960
961- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
962 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
963 now allow Python to make use of memory blocks exceeding 2**32 bytes for
964 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
965 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000966
Neal Norwitzfc76d632006-01-10 06:03:13 +0000967- Patch #1400181, fix unicode string formatting to not use the locale.
968 This is how string objects work. u'%f' could use , instead of .
969 for the decimal point. Now both strings and unicode always use periods.
970
Neal Norwitz671b9e32006-01-09 07:07:12 +0000971- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
972 configure would break checking curses.h.
973
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000974- Bug #959576: The pwd module is now builtin. This allows Python to be
975 built on UNIX platforms without $HOME set.
976
Neal Norwitzc10978f2005-12-19 06:07:16 +0000977- Bug #1072182, fix some potential problems if characters are signed.
978
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000979- Bug #889500, fix line number on SyntaxWarning for global declarations.
980
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000981- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
982
Neal Norwitze7214a12005-12-18 05:03:17 +0000983- Support for converting hex strings to floats no longer works.
984 This was not portable. float('0x3') now raises a ValueError.
985
Barry Warsaw2a38a862005-12-18 01:27:35 +0000986- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000987 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000988 is now displayed in interactive prompt banner.
989
Georg Brandlfa166682005-12-17 21:45:17 +0000990- Implementation of PEP 341 - Unification of try/except and try/finally.
991 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000992 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000993
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000994- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
995 now encodes backslash correctly.
996
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000997- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
998
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000999- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001000 and long longs.
1001
Neal Norwitz67715f02005-11-09 06:59:35 +00001002- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001003 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001004 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001005
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001006- Replaced most Unicode charmap codecs with new ones using the
1007 new Unicode translate string feature in the builtin charmap
1008 codec; the codecs were created from the mapping tables available
1009 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1010 encodings now include a mapping for the Apple logo)
1011
Tim Peterse3547fd2005-12-16 23:13:57 +00001012- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001013
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001014- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001015
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001016- A new AST parser implementation was completed. The abstract
1017 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001018 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001019
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001020- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001021 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1022
Neal Norwitz708e51a2005-10-03 04:48:15 +00001023- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1024
Neal Norwitz11bd1192005-10-03 00:54:56 +00001025- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1026 Provide a warning when a directory is passed on the command line.
1027
Neal Norwitz40d37812005-10-02 01:48:49 +00001028- Fix segfault with invalid coding.
1029
1030- SF bug #772896: unknown encoding results in MemoryError.
1031
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001032- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001033 supported a __len__() method which evaluated to False when the iterator
1034 was empty.
1035
Guido van Rossum630db602005-09-20 18:49:54 +00001036- On 64-bit platforms, when __len__() returns a value that cannot be
1037 represented as a C int, raise OverflowError.
1038
Skip Montanarof8948ca2005-09-19 03:54:46 +00001039- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001040 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001041
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001042- SF bug #893549: parsing keyword arguments was broken with a few format
1043 codes.
1044
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001045- Changes donated by Elemental Security to make it work on AIX 5.3
1046 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1047 bug #105470: test_pwd fails on 64bit system (Opteron).
1048
Guido van Rossum539c6622005-09-14 17:49:54 +00001049- Changes donated by Elemental Security to make it work on HP-UX 11 on
1050 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1051
Georg Brandl4550b8d2005-08-26 06:43:52 +00001052- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001053 (fixes bug #1119418).
1054
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001055- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1056
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001057- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1058 exceptions that cause a function to exit.
1059
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001060- The implementation of set() and frozenset() was revised to use its
1061 own internal data structure. Memory consumption is reduced by 1/3
1062 and there are modest speed-ups as well. The API is unchanged.
1063
Tim Petersde7990b2005-07-17 23:45:23 +00001064- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1065
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001066- SF bug #1229429: PyObject_CallMethod failed to decrement some
1067 reference counts in some error exit cases.
1068
Tim Petersecc6e6a2005-07-10 22:30:55 +00001069- SF bug #1185883: Python's small-object memory allocator took over
1070 a block managed by the platform C library whenever a realloc specified
1071 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001072 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001073 portable way to copy data from the C-managed block into Python's
1074 small-object space without risking a memory fault. Python's small-object
1075 realloc now leaves such blocks under the control of the platform C
1076 realloc.
1077
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001078- SF bug #1232517: An overflow error was not detected properly when
1079 attempting to convert a large float to an int in os.utime().
1080
Raymond Hettinger3296e692005-06-29 23:29:56 +00001081- SF bug #1224347: hex longs now print with lowercase letters just
1082 like their int counterparts.
1083
Michael W. Hudson188d4362005-06-20 16:52:57 +00001084- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1085 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1086 interpreter states; back out that fix and do a better job (see
1087 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1088 for a longer write-up of the problem).
1089
Michael W. Hudsondf888462005-06-03 14:41:55 +00001090- SF patch #1180995: marshal now uses a binary format by default when
1091 serializing floats.
1092
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001093- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1094 the routines that promise to produce IEEE 754 binary representations
1095 of floats now simply copy bytes around.
1096
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001097- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1098 278.
1099
Brett Cannonc3647ac2005-04-26 03:45:26 +00001100- patch #1109424: int, long, float, complex, and unicode now check for the
1101 proper magic slot for type conversions when subclassed. Previously the
1102 magic slot was ignored during conversion. Semantics now match the way
1103 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001104 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001105 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001106 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001107
Barry Warsawc8d907c2005-04-19 23:43:40 +00001108- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1109 NULL, now raise an AttributeError when attempting to set or delete the
1110 attribute. Previously a TypeError was raised, but this was inconsistent
1111 with the equivalent pure-Python implementation.
1112
Michael W. Hudson774479c2005-04-18 08:46:17 +00001113- It is now safe to call PyGILState_Release() before
1114 PyEval_InitThreads() (note that if there is reason to believe there
1115 are multiple threads around you still must call PyEval_InitThreads()
1116 before using the Python API; this fix is for extension modules that
1117 have no way of knowing if Python is multi-threaded yet).
1118
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001119- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1120 disabled caused a crash.
1121
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001122- Bug #1165306: instancemethod_new allowed the creation of a method
1123 with im_class == im_self == NULL, which caused a crash when called.
1124
Tim Petersecc6e6a2005-07-10 22:30:55 +00001125- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001126 fixes the crash seen in bug #1165761
1127
Raymond Hettinger96229b12005-03-11 06:49:40 +00001128- Added two new builtins, any() and all().
1129
Brett Cannon409d8f22005-03-05 06:47:57 +00001130- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001131 (e.g., ``class C(): pass`` is no longer a syntax error).
1132 Patch #1176012 added support to the 'parser' module and 'compiler' package
1133 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001134
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001135- Patch #1115086: Support PY_LONGLONG in structmember.
1136
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001137- Bug #1155938: new style classes did not check that __init__() was
1138 returning None.
1139
Tim Petersecc6e6a2005-07-10 22:30:55 +00001140- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001141 ('\') with a specific error message.
1142
Martin v. Löwisff232d72005-03-03 09:24:38 +00001143- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1144
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001145- Bug #1124295: the __name__ attribute of file objects was
1146 inadvertently made inaccessible in restricted mode.
1147
Tim Petersecc6e6a2005-07-10 22:30:55 +00001148- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001149 an ferror() call.
1150
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001151- min() and max() now support key= arguments with the same meaning as in
1152 list.sort().
1153
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001154- The peephole optimizer now performs simple constant folding in expressions:
1155 (2+3) --> (5).
1156
Raymond Hettingera422c342005-01-11 03:03:27 +00001157- set and frozenset objects can now be marshalled. SF #1098985.
1158
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001159- Bug #1077106: Poor argument checking could cause memory corruption
1160 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001161
Jeremy Hyltonab630502005-02-04 18:44:06 +00001162- The parser did not complain about future statements in illegal
1163 positions. It once again reports a syntax error if a future
1164 statement occurs after anything other than a doc string.
1165
Neil Schemenauercf52c072005-08-12 17:34:58 +00001166- Change the %s format specifier for str objects so that it returns a
1167 unicode instance if the argument is not an instance of basestring and
1168 calling __str__ on the argument returns a unicode instance.
1169
Tim Petersf4e69282006-02-27 17:15:31 +00001170- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1171 current thread state when the auto-GIL-state machinery knows about
1172 it (since the thread state is being deleted, continuing to remember it
1173 can't help, but can hurt if another thread happens to get created with
1174 the same thread id).
1175
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001176Extension Modules
1177-----------------
1178
Georg Brandl43f08a82006-03-31 18:01:16 +00001179- Patch #1380952: fix SSL objects timing out on consecutive read()s
1180
Neal Norwitz05a45592006-03-20 06:30:08 +00001181- Patch #1309579: wait3 and wait4 were added to the posix module.
1182
Anthony Baxterfa869072006-03-20 05:21:58 +00001183- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1184 In addition, the existing ulaw code was updated.
1185
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001186- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001187 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001188
Neal Norwitz10be10c2006-03-16 06:50:13 +00001189- Everything under lib-old was removed. This includes the following modules:
1190 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001191 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001192 util, whatsound, whrandom, zmod
1193
1194- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1195
1196- re and sre were swapped, so help(re) provides full help. importing sre

1352
Raymond Hettingerb2594052004-12-05 09:25:51 +00001353- itertools.islice() now accepts None for the start and step arguments.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001366- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1367 been renamed to have only a single underscore prefix. This was done to
1368 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001369
Nick Coghlan43832302006-04-23 17:04:07 +00001370- PEP 338: new module runpy defines a run_module function to support
1371 executing modules which provide access to source code or a code object
1372 via the PEP 302 import mechanisms.
1373
Anthony Baxter93f5b932006-04-03 08:05:07 +00001374- The email module's parsedate_tz function now sets the daylight savings

1382 in attribute values.
1383
Anthony Baxterc51ee692006-04-01 00:57:31 +00001384- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001385 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001386 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001387 module will not be built.
1388
Tim Petersc17976e2006-04-01 00:26:53 +00001389- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1390 aren't officially supported here, and trying to use them will probably
1391 raise an exception some day. But dicts have been allowed, and "mostly
1392 worked", so support for them won't go away without warning.
1393
Georg Brandl338ef7d2006-03-31 18:42:16 +00001394- Bug #1445068: getpass.getpass() can now be given an explicit stream
1395 argument to specify where to write the prompt.

1412
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001413- email 4.0 package now integrated. This is largely the same as the email 3.0
1414 package that was included in Python 2.3, except that PEP 8 module names are
1415 now used (e.g. mail.message instead of email.Message). The MIME classes
1416 have been moved to a subpackage (e.g. email.mime.text instead of
1417 email.MIMEText). The old names are still supported for now. Several
1418 deprecated Message methods have been removed and lots of bugs have been
1419 fixed. More details can be found in the email package documentation.
1420
Walter Dörwald40108c92006-03-27 08:15:44 +00001421- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1422 (a subclass of tuple) that provides incremental decoders and encoders
1423 (a way to use stateful codecs without the stream API). Python functions
1424 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1425 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1426 have been added.

1429 a ValueError instead of a StopIteration now (like file and cString.String do).
1430 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1431 called before (like file and StringIO.StringIO do).

1501 LoadError as documented, instead of IOError. For compatibility,
1502 LoadError subclasses IOError.
1503
Brett Cannon3cbd0382005-12-16 22:49:23 +00001504- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001505 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1506 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1507 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1508 Ronald L. Rivest offered this advice for Python:
1509
1510 "The consensus of researchers in this area (at least as
1511 expressed at the NIST Hash Function Workshop 10/31/05),
1512 is that SHA-256 is a good choice for the time being, but
1513 that research should continue, and other alternatives may
1514 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001515
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001516- Added a subset of Fredrik Lundh's ElementTree package. Available

1635 work as expected.
1636
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001637- Bug #1163325: Decimal infinities failed to hash. Attempting to

Guido van Rossumd0641422005-02-03 15:01:24 +00001675- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1676 disables recursive traversal through instance attributes, which can
1677 be exploited in various ways.
1678
Tim Peterse3547fd2005-12-16 23:13:57 +00001679- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec

1693
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001694- Enhancements to the csv module:
1695
1696 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001697 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001698 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001699 + Dialect parameter parsing has been re-implemented to improve error
1700 reporting.
1701 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1702 dictates.
1703 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001704 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001705 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001706 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1707 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001708 + reader now allows \r characters to be quoted (previously it only allowed
1709 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001710 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001711 + Dialect classes passed to the module are no longer instantiated by
1712 the module before being parsed (the former validation scheme required
1713 this, but the mechanism was unreliable).
1714 + The dialect registry now contains instances of the internal
1715 C-coded dialect type, rather than references to python objects.
1716 + the internal c-coded dialect type is now immutable.
1717 + register_dialect now accepts the same keyword dialect specifications
1718 as the reader and writer, allowing the user to register dialects
1719 without first creating a dialect class.
1720 + a configurable limit to the size of parsed fields has been added -
1721 previously, an unmatched quote character could result in the entire
1722 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001723 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001724 the parser field size limit (returning the former limit). The initial
1725 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001726 + A line_num attribute has been added to the reader object, which tracks
1727 the number of lines read from the source iterator. This is not
1728 the same as the number of records returned, as records can span
1729 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001730 + reader and writer objects were not being registered with the cyclic-GC.
1731 This has been fixed.
1732
Brett Cannone6539c42005-01-08 02:43:53 +00001733- _DummyThread objects in the threading module now delete self.__block that is
1734 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1735 lock primitives tend to be limited in number and thus should not be wasted on
1736 a _DummyThread object. Fixes bug #1089632.
1737
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001738- The imghdr module now detects Exif files.
1739
Raymond Hettinger6065d322004-12-20 23:51:53 +00001740- StringIO.truncate() now correctly adjusts the size attribute.
1741 (Bug #951915).
1742
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001743- locale.py now uses an updated locale alias table (built using
1744 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1745 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001746 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001747
Raymond Hettinger3557f422004-12-07 12:02:02 +00001748- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1749
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001750- the pickle module no longer accepts the deprecated None option in the
1751 args tuple returned by __reduce__().
1752
Brett Cannon84667c02004-12-07 03:25:18 +00001753- optparse now optionally imports gettext. This allows its use in setup.py.
1754
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001755- the pickle module no longer uses the deprecated bin parameter.
1756
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001757- the shelve module no longer uses the deprecated binary parameter.
1758
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001759- the pstats module no longer uses the deprecated ignore() method.
1760
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001761- the filecmp module no longer uses the deprecated use_statcache argument.
1762
Raymond Hettinger664347b2004-12-04 21:21:53 +00001763- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1764 extended or overridden by subclasses. Formerly, the subclassed method would
1765 be ignored by the rest of the module. (Bug #1078905).
1766
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001767- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001768 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001769
Walter Dörwald36733692004-12-22 12:50:50 +00001770- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1771 once when a size argument is given. This prevents a buffer overflow in the
1772 tokenizer with very long source lines.
1773
Barry Warsaw538561e2006-01-01 21:48:54 +00001774- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1775 immediately after creating the object, without any intervening
1776 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001777
Skip Montanaro05885812005-01-16 20:48:27 +00001778- The reconvert.quote function can now emit triple-quoted strings. The
1779 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001780
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001781- ``UserString.MutableString`` now supports negative indices in
1782 ``__setitem__`` and ``__delitem__``
1783
Greg Ward40407942005-03-05 02:53:17 +00001784- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1785 correctly.
1786
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001787- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1788 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1789 character even if the user has passed a size parameter to get a proper
1790 line ending. Remove the special handling of a "\r\n" that has been split
1791 between two lines.
1792
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001793- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1794 about illegal code points. The codec now supports PEP 293 style error
1795 handlers.
1796
Walter Dörwald78a78b02005-09-01 12:04:29 +00001797- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001798 from the input stream, so that the output is a byte string in the correct
1799 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001800
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001801- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1802 considering it exactly like a '*'.
1803
Walter Dörwald007f8df2005-10-09 19:42:27 +00001804- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1805 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001806
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001807- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1808
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001809- Patch #1413711: Certain patterns of differences were making difflib
1810 touch the recursion limit.
1811
Walter Dörwald58917a62006-03-31 15:26:22 +00001812- Bug #947906: An object oriented interface has been added to the calendar
1813 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001814 called as a script (e.g. via ``python -mcalendar``). Localized month and
1815 weekday names can be ouput (even if an exotic encoding is used) using
1816 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001817
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001818Build
1819-----
1820
Neal Norwitz602d3392006-03-31 08:21:40 +00001821- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1822 by using -mieee gcc option.
1823
Martin v. Löwis86d66262006-02-17 08:40:11 +00001824- Patch #1432345: Make python compile on DragonFly.
1825
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001826- Build support for Win64-AMD64 was added.
1827
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001828- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1829
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001830- Patch #881820: look for openpty and forkpty also in libbsd.
1831
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001832- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1833 The zlib module is now builtin on Windows.
1834
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001835- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1836
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001837- Bug #1189330: configure did not correctly determine the necessary
1838 value of LINKCC if python was built with GCC 4.0.
1839
Trent Mick8321b422005-07-26 02:29:21 +00001840- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1841 vulnerability in zlib 1.2.1 and 1.2.2.
1842
Brett Cannon08cd5982005-04-24 22:26:38 +00001843- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1844 flags that change binary compatibility. Changes were also made to
1845 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001846 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001847
Bob Ippolitoed233462005-03-29 13:47:59 +00001848- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1849 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1850 no longer exists). This configure patch makes things right.
1851
Martin v. Löwise2713be2005-03-08 15:03:08 +00001852- Bug #1158607: Build with --disable-unicode again.
1853
Brett Cannon46d96232005-02-16 00:07:19 +00001854- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1855 defined. Discovered as a result of not being able to build on OS X.
1856
Brett Cannon516592f2004-12-07 00:42:59 +00001857- setup.py now uses the directories specified in LDFLAGS using the -L option
1858 and in CPPFLAGS using the -I option for adding library and include
1859 directories, respectively, for compiling extension modules against. This has
1860 led to the core being compiled using the values in CPPFLAGS. It also removes
1861 the need for the special-casing of both DarwinPorts and Fink for darwin since
1862 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1863 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1864 Fink, ``-I/opt/local/include`` for DarwinPorts).
1865
Brett Cannon43802422005-02-10 20:48:03 +00001866- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1867 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1868 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1869 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001871C API
1872-----
1873
Tim Petersc9d78aa2006-03-26 23:27:58 +00001874- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1875 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1876 is obtained via the ``PyObject_`` family, it must be released via the
1877 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1878 always been officially true, but when Python's small-object allocator was
1879 introduced, an attempt was made to cater to a few extension modules
1880 discovered at the time that obtained memory via ``PyObject_New`` but
1881 released it via ``PyMem_DEL``. It's years later, and if such code still
1882 exists it will fail now (probably with segfaults, but calling wrong
1883 low-level memory management functions can yield many symptoms).
1884
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001885- Added a C API for set and frozenset objects.
1886
Raymond Hettinger66517482004-12-03 11:45:13 +00001887- Removed PyRange_New().
1888
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001889- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1890 mapping argument now. This string is used as a mapping table. Byte values
1891 greater than the length of the string and 0xFFFE are treated as undefined
1892 mappings.
