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

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

Georg Brandlad29e632006-06-21 17:45:17 +0000189What's New in Python 2.5 beta 2?
190================================

Anthony Baxter70e8e872006-07-10 07:41:04 +0000192*Release date: 11-JUL-2006*
Georg Brandlad29e632006-06-21 17:45:17 +0000193
194Core and builtins
195-----------------
196
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000197- Bug #1441486: The literal representation of -(sys.maxint - 1)
198 again evaluates to a int object, not a long.
199
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000200- Bug #1501934: The scope of global variables that are locally assigned
201 using augmented assignment is now correctly determined.
202
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000203- Bug #927248: Recursive method-wrapper objects can now safely
204 be released.
205
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000206- Bug #1417699: Reject locale-specific decimal point in float()
207 and atof().
208
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000209- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
210 omit a default "error" argument for NULL pointer. This allows
211 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000212
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000213- Bug #1519018: 'as' is now validated properly in import statements.
214
Neal Norwitz28746ab2006-07-09 22:14:42 +0000215- On 64 bit systems, int literals that use less than 64 bits are
216 now ints rather than longs.
217
Neal Norwitzed657552006-07-10 00:04:44 +0000218- Bug #1512814, Fix incorrect lineno's when code at module scope
219 started after line 256.
220
Tim Peters32a83612006-07-10 21:08:24 +0000221- New function ``sys._current_frames()`` returns a dict mapping thread
222 id to topmost thread stack frame. This is for expert use, and is
223 especially useful for debugging application deadlocks. The functionality
224 was previously available in Fazal Majid's ``threadframe`` extension
225 module, but it wasn't possible to do this in a wholly threadsafe way from
226 an extension.
227

229-------
230
Martin v. Löwis77621582006-07-30 13:27:31 +0000231- Bug #1257728: Mention Cygwin in distutils error message about a missing
232 VS 2003.
233
Martin v. Löwis06c68b82006-07-10 22:11:28 +0000234- Patch #1519566: Update turtle demo, make begin_fill idempotent.
235
Tim Peters32a83612006-07-10 21:08:24 +0000236- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000237 environment variable to be set in order to the SDK environment
238 for finding the compiler, include files, etc.
239

243
Thomas Woutersadd19112006-07-05 11:03:49 +0000244- string.Template() now correctly handles tuple-values. Previously,
245 multi-value tuples would raise an exception and single-value tuples would
246 be treated as the value they contain, instead.
247
Martin v. Löwisede77f52006-07-03 13:01:35 +0000248- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

255 degrees and radians.
256
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000257- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000258 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000259
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000260- Bug #1514703: Only setup canvas window in turtle when the canvas
261 is created.

270 sgmllib ('[' and ']' were not accepted).
271
Georg Brandl1be63af2006-06-28 20:23:25 +0000272- Fix a bug in the turtle module's end_fill function.
273
Brett Cannon53ab5b72006-06-22 16:49:14 +0000274- Bug #1510580: The 'warnings' module improperly required that a Warning
275 category be either a types.ClassType and a subclass of Warning. The proper
276 check is just that it is a subclass with Warning as the documentation states.
277
Georg Brandlad29e632006-06-21 17:45:17 +0000278- The compiler module now correctly compiles the new try-except-finally
279 statement (bug #1509132).
280
Neal Norwitz60373cd2006-06-22 06:30:50 +0000281- The wsgiref package is now installed properly on Unix.
282
Vinay Sajip28e57612006-07-01 10:45:20 +0000283- A bug was fixed in logging.config.fileConfig() which caused a crash on
284 shutdown when fileConfig() was called multiple times.
285
Gerhard Häring762fbd32006-07-02 17:48:30 +0000286- The sqlite3 module did cut off data from the SQLite database at the first
287 null character before sending it to a custom converter. This has been fixed
288 now.
289
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000290Extension Modules
291-----------------
292
Tim Peters112aad32006-07-19 00:03:19 +0000293- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
294 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
295 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000296
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000297- Assigning None to pointer type fields in ctypes structures possible
298 overwrote the wrong fields, this is fixed now.
299
300- Fixed a segfault in _ctypes when ctypes.wintypes were imported
301 on non-Windows platforms.
302
303- Bug #1518190: The ctypes.c_void_p constructor now accepts any
304 integer or long, without range checking.
305
306- Patch #1517790: It is now possible to use custom objects in the ctypes
307 foreign function argtypes sequence as long as they provide a from_param
308 method, no longer is it required that the object is a ctypes type.
309
310- The '_ctypes' extension module now works when Python is configured
311 with the --without-threads option.

326
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000327- Automate Windows build process for the Win64 SSL module.
328
Tim Peters32a83612006-07-10 21:08:24 +0000329- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000330 Previously, the slight difference could cause compilation errors of the
331 'zlib' module on systems with more than one version of zlib.
332
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000333- The MSI compileall step was fixed to also support a TARGETDIR
334 with spaces in it.
335
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000336- Bug #1517388: sqlite3.dll is now installed on Windows independent
337 of Tcl/Tk.
338
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000339- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old

Anthony Baxter51bcb682006-04-05 14:51:42 +0000360
Anthony Baxterd1136802006-06-19 12:04:15 +0000361*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000362
363Core and builtins
364-----------------
365
Georg Brandla56b9152006-06-19 06:35:54 +0000366- Patch #1507676: Error messages returned by invalid abstract object operations
367 (such as iterating over an integer) have been improved and now include the
368 type of the offending object to help with debugging.
369
Brett Cannonea3912b2006-06-13 21:46:41 +0000370- Bug #992017: A classic class that defined a __coerce__() method that returned
371 its arguments swapped would infinitely recurse and segfault the interpreter.
372
Neal Norwitz909eb122006-06-12 02:13:21 +0000373- Fix the socket tests so they can be run concurrently.
374
Neal Norwitzb9845e72006-06-12 02:11:18 +0000375- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000376 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000377
Brett Cannon22565aa2006-06-09 22:31:23 +0000378- Bug #532646: object.__call__() will continue looking for the __call__
379 attribute on objects until one without one is found. This leads to recursion
380 when you take a class and set its __call__ attribute to an instance of the
381 class. Originally fixed for classic classes, but this fix is for new-style.
382 Removes the infinite_rec_3 crasher.
383
Georg Brandl24250812006-06-09 18:45:48 +0000384- The string and unicode methods startswith() and endswith() now accept
385 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
386
Brett Cannonde3b0522006-06-08 17:00:45 +0000387- Buffer objects, at the C level, never used the char buffer
388 implementation even when the char buffer for the wrapped object was
389 explicitly requested (originally returned the read or write buffer).
390 Now a TypeError is raised if the char buffer is not present but is
391 requested.
392
Georg Brandlddbaa662006-06-04 21:56:52 +0000393- Patch #1346214: Statements like "if 0: suite" are now again optimized
394 away like they were in Python 2.4.
395
Georg Brandlb7c8f542006-05-27 12:30:25 +0000396- Builtin exceptions are now full-blown new-style classes instead of
397 instances pretending to be classes, which speeds up exception handling
398 by about 80% in comparison to 2.5a2.
399
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000400- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
401 Unicode 4.1.
402
Georg Brandlf4ef1162006-05-26 18:03:31 +0000403- Patch #921466: sys.path_importer_cache is now used to cache valid and
404 invalid file paths for the built-in import machinery which leads to
405 fewer open calls on startup.
406
Tim Peters696cf432006-05-24 21:10:40 +0000407- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
408 of-2 bases. The largest speedup is for inputs with about 1000 decimal
409 digits. Conversion from non-power-of-2 bases remains quadratic-time in
410 the number of input digits (it was and remains linear-time for bases
411 2, 4, 8, 16 and 32).
412
Tim Petersb713ec22006-05-23 18:45:30 +0000413- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
414 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
415 an integer close to ``sys.maxint``. This was repaired by patch
416 #1335972, which also gives a nice speedup.
417
Richard Jonescebbefc2006-05-23 18:28:17 +0000418- Patch #1337051: reduced size of frame objects.
419
420- PyErr_NewException now accepts a tuple of base classes as its
421 "base" parameter.
422
Richard Jones7c88dcc2006-05-23 10:37:38 +0000423- Patch #876206: function call speedup by retaining allocated frame
424 objects.
425
Georg Brandl7b90e162006-05-18 07:01:27 +0000426- Bug #1462152: file() now checks more thoroughly for invalid mode
427 strings and removes a possible "U" before passing the mode to the
428 C library function.
429
Neal Norwitz1004a532006-05-15 07:17:23 +0000430- Patch #1488312, Fix memory alignment problem on SPARC in unicode
431
Neal Norwitz373f0a72006-05-15 07:04:36 +0000432- Bug #1487966: Fix SystemError with conditional expression in assignment
433
Martin v. Löwis879768d2006-05-11 13:28:43 +0000434- WindowsError now has two error code attributes: errno, which carries
435 the error values from errno.h, and winerror, which carries the error
436 values from winerror.h. Previous versions put the winerror.h values
437 (from GetLastError()) into the errno attribute.
438
Martin v. Löwis77736712006-05-04 05:51:03 +0000439- Patch #1475845: Raise IndentationError for unexpected indent.
440
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000441- Patch #1479181: split open() and file() from being aliases for each other.
442
Tim Peters44bd9862006-06-01 13:49:23 +0000443- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
444 methods were always silently ignored by dictionaries when comparing keys.
445 They are now passed through (except when using the C API function
446 ``PyDict_GetItem()``, whose semantics did not change).
447
448- Bug #1456209: In some obscure cases it was possible for a class with a
449 custom ``__eq__()`` method to confuse dict internals when class instances
450 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
451 No, you don't have any code that did this ;-)

457
458- Patch #1462338: Upgrade pyexpat to expat 2.0.0
459
Brett Cannon6ee7d012006-06-08 16:23:04 +0000460- Change binascii.hexlify to accept a read-only buffer instead of only a char
461 buffer and actually follow its documentation.
462
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000463- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
464
Nick Coghlanc649ec52006-05-29 12:43:05 +0000465- Patch #1478788 (modified version): The functional extension module has
466 been renamed to _functools and a functools Python wrapper module added.
467 This provides a home for additional function related utilities that are
468 not specifically about functional programming. See PEP 309.
469
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000470- Patch #1493701: performance enhancements for struct module.
471
Georg Brandl378d5922006-05-17 14:26:50 +0000472- Patch #1490224: time.altzone is now set correctly on Cygwin.
473
Georg Brandl8d3342b2006-05-16 07:38:27 +0000474- Patch #1435422: zlib's compress and decompress objects now have a
475 copy() method.
476
Andrew MacIntyre92913322006-06-13 15:04:24 +0000477- Patch #1454481: thread stack size is now tunable at runtime for thread
478 enabled builds on Windows and systems with Posix threads support.
479
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000480- On Win32, os.listdir now supports arbitrarily-long Unicode path names
481 (up to the system limit of 32K characters).
482
483- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
484 As a result, these functions now raise WindowsError instead of OSError.
485
Tim Peters7a822da2006-05-25 21:50:17 +0000486- ``time.clock()`` on Win64 should use the high-performance Windows
487 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
488 Windows platforms).
489
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000490- Calling Tk_Init twice is refused if the first call failed as that
491 may deadlock.
492
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000493- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
494 accept it without potentially using an uninitialized pointer.
495
496- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
497 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
498 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000499
Gregory P. Smith372b5832006-06-05 18:48:21 +0000500- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000501 [pybsddb project SF patch number 1466734]
502
Gregory P. Smith372b5832006-06-05 18:48:21 +0000503- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
504 parameter is supplied. [SF pybsddb bug #1477863]
505
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000506- bsddb: the __len__ method of a DB object has been fixed to return correct
507 results. It could previously incorrectly return 0 in some cases.
508 Fixes SF bug 1493322 (pybsddb bug 1184012).
509
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000510- bsddb: the bsddb.dbtables Modify method now raises the proper error and
511 aborts the db transaction safely when a modifier callback fails.
512 Fixes SF python patch/bug #1408584.
513
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000514- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000515 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000516 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
517 database calls that would previously deadlock. [SF python bug #775414]
518
Vinay Sajip28e57612006-07-01 10:45:20 +0000519- Patch #1446489: add support for the ZIP64 extensions to zipfile.

525-------
526
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000527- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
528 functions.
529
Martin v. Löwis3798da02006-06-17 18:44:27 +0000530- Patch #812986: Update turtle output even if not tracing.
531
Vinay Sajip28e57612006-07-01 10:45:20 +0000532- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000533 Tkinter.BaseWidget.
534
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000535- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
536
Martin v. Löwis337487e2006-06-17 09:15:14 +0000537- Patch #763580: Add name and value arguments to Tkinter variable
538 classes.
539
Georg Brandl83cc0d02006-06-14 08:50:03 +0000540- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
541 mime.types file for determining MIME types.
542
Georg Brandl2605ca82006-06-14 06:08:31 +0000543- Bug #1339007: Shelf objects now don't raise an exception in their
544 __del__ method when initialization failed.
545
Martin v. Löwisd8251432006-06-14 05:21:04 +0000546- Patch #1455898: The MBCS codec now supports the incremental mode for
547 double-byte encodings.
548
Tim Peters43898b42006-06-14 04:09:25 +0000549- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
550 guarantee that adjacent triples in the return list always describe
551 non-adjacent blocks. Previously, a pair of matching blocks could end
552 up being described by multiple adjacent triples that formed a partition
553 of the matching pair.
554
Greg Ward0e0c9f42006-06-11 16:24:11 +0000555- Bug #1498146: fix optparse to handle Unicode strings in option help,
556 description, and epilog.
557
Greg Wardd1c797e2006-06-11 14:42:41 +0000558- Bug #1366250: minor optparse documentation error.
559
Greg Ward7f547402006-06-11 00:40:49 +0000560- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
561 clarify docs.
562
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000563- The wsgiref package has been added to the standard library.
564
Nick Coghlan676725d2006-06-08 13:54:49 +0000565- The functions update_wrapper() and wraps() have been added to the functools
566 module. These make it easier to copy relevant metadata from the original
567 function when writing wrapper functions.
568
Tim Petersd6a9eef2006-06-05 01:48:21 +0000569- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
570 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000571
Martin v. Löwis3f767792006-06-04 19:36:28 +0000572- Patch #1359618: Speed up charmap encoder by using a trie structure
573 for lookup.
574
Tim Petersd609b1a2006-06-02 23:22:51 +0000575- The functions in the ``pprint`` module now sort dictionaries by key
576 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
577 if and only if its display required more than one line, although that
578 wasn't documented. The new behavior increases predictability; e.g.,
579 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
580
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000581- Patch #1497027: try HTTP digest auth before basic auth in urllib2
582 (thanks for J. J. Lee).
583
Georg Brandl2b330372006-05-28 20:23:12 +0000584- Patch #1496206: improve urllib2 handling of passwords with respect to
585 default HTTP and HTTPS ports.
586
George Yoshidaf3c65de2006-05-28 16:39:09 +0000587- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
588
Bob Ippolito7298f272006-05-23 18:43:47 +0000589- Patch #1281707: speed up gzip.readline.
590
Georg Brandlb89316f2006-05-17 15:51:16 +0000591- Patch #1180296: Two new functions were added to the locale module:
592 format_string() to get the effect of "format % items" but locale-aware,
593 and currency() to format a monetary number with currency sign.
594
Georg Brandle3a25832006-05-17 14:56:04 +0000595- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
596 and several features added, such as speed and geometry control.
597
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000598- Patch #1488881: add support for external file objects in bz2 compressed
599 tarfiles.
600
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000601- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
602 stdout arguments, making it possible to redirect input and output
603 for remote debugging.
604
605- Patch #1484695: Update the tarfile module to version 0.8. This fixes
606 a couple of issues, notably handling of long file names using the
607 GNU LONGNAME extension.
608
609- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
610 new flag when ``name`` is already the name of an option flag.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000651What's New in Python 2.5 alpha 2?
652=================================
653
654*Release date: 27-APR-2006*
655
656Core and builtins
657-----------------
658
Thomas Heller1b046642006-04-18 18:51:06 +0000659- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
660 by converting these apis from macros into exported functions again:
661
662 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
663 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
664 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
665 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
666 PyRun_String Py_CompileString
667
Martin v. Löwis45294a92006-04-18 06:24:08 +0000668- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
669
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000670- All uses of PyStructSequence_InitType have been changed to initialize
671 the type objects only once, even if the interpreter is initialized
672 multiple times.
673
Neal Norwitz61546162006-04-14 05:20:28 +0000674- Bug #1454485, array.array('u') could crash the interpreter. This was
675 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
676 to unicode when it didn't make sense. 'u#' now requires a unicode string.
677
678- Py_UNICODE is unsigned. It was always documented as unsigned, but
679 due to a bug had a signed value in previous versions.
680
Tim Peters3a5e8b12006-04-11 01:44:07 +0000681- Patch #837242: ``id()`` of any Python object always gives a positive
682 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
683 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000684 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000685 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000686
Tim Peters3a5e8b12006-04-11 01:44:07 +0000687 def __hash__(self):
688 return id(self) # WRONG
689
690 because a hash result must be a (short) Python int but it was always
691 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000692 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000693 was always usable as a hash value before this patch. That's no longer
694 necessarily so.
695
696- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000697 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000698 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000699 #1454844)
700
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000701- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
702 involving generators that have paused outside of any ``try`` or ``with``
703 blocks. (In 2.5a1, a paused generator that was part of a reference
704 cycle could not be garbage collected, regardless of whether it was
705 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000707Extension Modules
708-----------------
709
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000710- Patch #1191065: Fix preprocessor problems on systems where recvfrom
711 is a macro.
712
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000713- Bug #1467952: os.listdir() now correctly raises an error if readdir()
714 fails with an error condition.
715
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000716- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
717
718- Bug #1117761: bsddb.*open() no longer raises an exception when using
719 the cachesize parameter.
720
721- Bug #1149413: bsddb.*open() no longer raises an exception when using
722 a temporary db (file=None) with the 'n' flag to truncate on open.
723
724- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
725 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000726
Armin Rigoa9017c32006-04-19 11:50:27 +0000727- Patch #1062014: AF_UNIX sockets under Linux have a special
728 abstract namespace that is now fully supported.
729
Anthony Baxter51bcb682006-04-05 14:51:42 +0000730Library
731-------
732
Peter Astrand7d1d4362006-07-14 14:04:45 +0000733- Bug #1223937: subprocess.CalledProcessError reports the exit status
734 of the process using the returncode attribute, instead of
735 abusing errno.
736
Tim Peters711bf302006-04-25 03:31:36 +0000737- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
738 a doctest to be skipped (the code is not run, and the expected output
739 or exception is ignored).
740
Nick Coghlanda2268f2006-04-24 04:37:15 +0000741- Fixed contextlib.nested to cope with exceptions being raised and
742 caught inside exit handlers.
743
Greg Wardab05edc2006-04-23 03:47:58 +0000744- Updated optparse module to Optik 1.5.1 (allow numeric constants in
745 hex, octal, or binary; add ``append_const`` action; keep going if
746 gettext cannot be imported; added ``OptionParser.destroy()`` method;
747 added ``epilog`` for better help generation).
748
Tim Peters21fbd572006-04-21 21:18:10 +0000749- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
750 called from a thread spawned as a side effect of importing a module.
751
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000752- The pydoc module now supports documenting packages contained in
753 .zip or .egg files.
754
755- The pkgutil module now has several new utility functions, such
756 as ``walk_packages()`` to support working with packages that are either
757 in the filesystem or zip files.
758
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000759- The mailbox module can now modify and delete messages from
760 mailboxes, in addition to simply reading them. Thanks to Gregory
761 K. Johnson for writing the code, and to the 2005 Google Summer of
762 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000763
Tim Petersc7605f22006-04-17 21:12:33 +0000764- The ``__del__`` method of class ``local`` in module ``_threading_local``
765 returned before accomplishing any of its intended cleanup.
766
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000767- Patch #790710: Add breakpoint command lists in pdb.
768
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000769- Patch #1063914: Add Tkinter.Misc.clipboard_get().
770
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000771- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
772
Anthony Baxtere29002c2006-04-12 12:07:31 +0000773- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
774 Windows. Bug #1469163.
775
Phillip J. Eby47032112006-04-11 01:07:43 +0000776- The warnings, linecache, inspect, traceback, site, and doctest modules
777 were updated to work correctly with modules imported from zipfiles or
778 via other PEP 302 __loader__ objects.
779
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000780- Patch #1467770: Reduce usage of subprocess._active to processes which
781 the application hasn't waited on.
782
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000783- Patch #1462222: Fix Tix.Grid.
784
Neal Norwitza31bf182006-04-09 03:35:43 +0000785- Fix exception when doing glob.glob('anything*/')
786
Skip Montanaro262fb922006-04-21 02:31:07 +0000787- The pstats.Stats class accepts an optional stream keyword argument to
788 direct output to an alternate file-like object.
789
Anthony Baxter51bcb682006-04-05 14:51:42 +0000790Build
791-----
792
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000793- The Makefile now has a reindent target, which runs reindent.py on
794 the library.
795
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000796- Patch #1470875: Building Python with MS Free Compiler
797
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000798- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000799
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000800- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
801 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000802 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000803 CXX from --with-cxx-main, see description in README.
804
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000805- Patch #1429775: Link extension modules with the shared libpython.
806
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000807- Fixed a libffi build problem on MIPS systems.
808
Tim Peters8931ff12006-05-13 23:28:20 +0000809- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
810 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
811 and "%zu" for unsigned integers of type ``size_t``.
812
Anthony Baxter51bcb682006-04-05 14:51:42 +0000813Tests
814-----
815
Nick Coghlanda2268f2006-04-24 04:37:15 +0000816- test_contextlib now checks contextlib.nested can cope with exceptions
817 being raised and caught inside exit handlers.
818
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000819- test_cmd_line now checks operation of the -m and -c command switches
820
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000821- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
822 it separately and by hand. It also wasn't cleaning up its changes to
823 the current Decimal context.
824
Thomas Woutersabd08882006-04-26 15:53:30 +0000825- regrtest.py now has a -M option to run tests that test the new limits of
826 containers, on 64-bit architectures. Running these tests is only sensible
827 on 64-bit machines with more than two gigabytes of memory. The argument
828 passed is the maximum amount of memory for the tests to use.

837-------------
838
Tim Petersb06d28c2006-05-12 01:57:59 +0000839- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
840
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000841- PEP 343: Added Context Types section to the library reference
842 and attempted to bring other PEP 343 related documentation into
843 line with the implementation and/or python-dev discussions.
844
Tim Peters8dc73d22006-04-24 02:03:16 +0000845- Bug #1337990: clarified that ``doctest`` does not support examples
846 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000849What's New in Python 2.5 alpha 1?
850=================================
851
Anthony Baxterebed3f62006-04-03 15:03:44 +0000852*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000853
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000854Core and builtins
855-----------------
856
Nick Coghlan43832302006-04-23 17:04:07 +0000857- PEP 338: -m command line switch now delegates to runpy.run_module
858 allowing it to support modules in packages and zipfiles
859
Martin v. Löwisc661b882006-04-20 04:54:23 +0000860- On Windows, .DLL is not an accepted file name extension for
861 extension modules anymore; extensions are only found if they
862 end in .PYD.
863
Martin v. Löwisea62d252006-04-03 10:56:49 +0000864- Bug #1421664: sys.stderr.encoding is now set to the same value as
865 sys.stdout.encoding.
866
Neal Norwitz92e212f2006-04-03 04:48:37 +0000867- __import__ accepts keyword arguments.
868
Georg Brandlccadf842006-03-31 18:54:53 +0000869- Patch #1460496: round() now accepts keyword arguments.
870
Anthony Baxter262c00a2006-03-30 10:53:17 +0000871- Fixed bug #1459029 - unicode reprs were double-escaped.
872
Hye-Shik Changd478f342006-03-23 12:32:36 +0000873- Patch #1396919: The system scope threads are reenabled on FreeBSD
874 5.4 and later versions.
875
Neal Norwitze98ccf62006-03-23 05:39:47 +0000876- Bug #1115379: Compiling a Unicode string with an encoding declaration
877 now gives a SyntaxError.
878
Georg Brandlabd1ff82006-03-18 07:59:59 +0000879- Previously, Python code had no easy way to access the contents of a
880 cell object. Now, a ``cell_contents`` attribute has been added
881 (closes patch #1170323).
882
Tim Peterscf79aac2006-03-16 01:14:46 +0000883- Patch #1123430: Python's small-object allocator now returns an arena to
884 the system ``free()`` when all memory within an arena becomes unused
885 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
886 freed. Some applications will see a drop in virtual memory size now,
887 especially long-running applications that, from time to time, temporarily
888 use a large number of small objects. Note that when Python returns an
889 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000890 platform C library will in turn return that memory to the operating system.
891 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000892 appears to be effective at least on Microsoft C and gcc-based systems.
893 Thanks to Evan Jones for hard work and patience.
894
Georg Brandl533ff6f2006-03-08 18:09:27 +0000895- Patch #1434038: property() now uses the getter's docstring if there is
896 no "doc" argument given. This makes it possible to legitimately use
897 property() as a decorator to produce a read-only property.
898
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000899- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
900 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
901 of requiring an int or long in slicing and a few other contexts, enabling
902 other objects (e.g. Numeric Python's integers) to be used as slice indices.
903
Neal Norwitz995acdf2006-03-07 05:01:00 +0000904- Fixed various bugs reported by Coverity's Prevent tool.
905
Brett Cannonbf364092006-03-01 04:25:17 +0000906- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
907 new exception base class, BaseException, which has a new message attribute.
908 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
909 Raising a string exception now raises a DeprecationWarning.
910
Thomas Woutersfb609f42006-02-28 16:37:25 +0000911- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
912 explicitly relative, using 'from .module import name' to mean 'from the same
913 package as this module is in. Imports without dots still default to the
914 old relative-then-absolute, unless 'from __future__ import
915 absolute_import' is used.
916
Brett Cannona7446e32006-02-27 23:39:10 +0000917- Properly check if 'warnings' raises an exception (usually when a filter set
918 to "error" is triggered) when raising a warning for raising string
919 exceptions.
920
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000921- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000922 The name was removed from Include/code.h.
923
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000924- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000925
Guido van Rossum1968ad32006-02-25 22:38:04 +0000926- Patch 1433928:
927 - The copy module now "copies" function objects (as atomic objects).
928 - dict.__getitem__ now looks for a __missing__ hook before raising
929 KeyError.

Tim Peters84ef21c2006-02-28 20:39:06 +0000931- PEP 343: with statement implemented. Needs ``from __future__ import
932 with_statement``. Use of 'with' as a variable will generate a warning.
933 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000934 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000935 The following objects have __context__ methods:
936 - The built-in file type.
937 - The thread.LockType type.
938 - The following types defined by the threading module:
939 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
940 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000941
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000942- Fix the encodings package codec search function to only search
943 inside its own package. Fixes problem reported in patch #1433198.
944
945 Note: Codec packages should implement and register their own
946 codec search function. PEP 100 has the details.
947
Tim Peters9ea89d22006-06-04 03:26:02 +0000948- PEP 353: Using ``Py_ssize_t`` as the index type.
949
950- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
951 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
952 now allow Python to make use of memory blocks exceeding 2**32 bytes for
953 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
954 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000955
Neal Norwitzfc76d632006-01-10 06:03:13 +0000956- Patch #1400181, fix unicode string formatting to not use the locale.
957 This is how string objects work. u'%f' could use , instead of .
958 for the decimal point. Now both strings and unicode always use periods.
959
Neal Norwitz671b9e32006-01-09 07:07:12 +0000960- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
961 configure would break checking curses.h.
962
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000963- Bug #959576: The pwd module is now builtin. This allows Python to be
964 built on UNIX platforms without $HOME set.
965
Neal Norwitzc10978f2005-12-19 06:07:16 +0000966- Bug #1072182, fix some potential problems if characters are signed.
967
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000968- Bug #889500, fix line number on SyntaxWarning for global declarations.
969
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000970- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
971
Neal Norwitze7214a12005-12-18 05:03:17 +0000972- Support for converting hex strings to floats no longer works.
973 This was not portable. float('0x3') now raises a ValueError.
974
Barry Warsaw2a38a862005-12-18 01:27:35 +0000975- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000976 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000977 is now displayed in interactive prompt banner.
978
Georg Brandlfa166682005-12-17 21:45:17 +0000979- Implementation of PEP 341 - Unification of try/except and try/finally.
980 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000981 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000982
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000983- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
984 now encodes backslash correctly.
985
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000986- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
987
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000988- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000989 and long longs.
990
Neal Norwitz67715f02005-11-09 06:59:35 +0000991- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000992 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000993 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000994
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000995- Replaced most Unicode charmap codecs with new ones using the
996 new Unicode translate string feature in the builtin charmap
997 codec; the codecs were created from the mapping tables available
998 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
999 encodings now include a mapping for the Apple logo)
1000
Tim Peterse3547fd2005-12-16 23:13:57 +00001001- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001002
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001003- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001004
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001005- A new AST parser implementation was completed. The abstract
1006 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001007 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001008
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001009- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001010 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1011
Neal Norwitz708e51a2005-10-03 04:48:15 +00001012- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1013
Neal Norwitz11bd1192005-10-03 00:54:56 +00001014- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1015 Provide a warning when a directory is passed on the command line.
1016
Neal Norwitz40d37812005-10-02 01:48:49 +00001017- Fix segfault with invalid coding.
1018
1019- SF bug #772896: unknown encoding results in MemoryError.
1020
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001021- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001022 supported a __len__() method which evaluated to False when the iterator
1023 was empty.
1024
Guido van Rossum630db602005-09-20 18:49:54 +00001025- On 64-bit platforms, when __len__() returns a value that cannot be
1026 represented as a C int, raise OverflowError.
1027
Skip Montanarof8948ca2005-09-19 03:54:46 +00001028- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001029 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001030
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001031- SF bug #893549: parsing keyword arguments was broken with a few format
1032 codes.
1033
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001034- Changes donated by Elemental Security to make it work on AIX 5.3
1035 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1036 bug #105470: test_pwd fails on 64bit system (Opteron).
1037
Guido van Rossum539c6622005-09-14 17:49:54 +00001038- Changes donated by Elemental Security to make it work on HP-UX 11 on
1039 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1040
Georg Brandl4550b8d2005-08-26 06:43:52 +00001041- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001042 (fixes bug #1119418).
1043
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001044- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1045
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001046- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1047 exceptions that cause a function to exit.
1048
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001049- The implementation of set() and frozenset() was revised to use its
1050 own internal data structure. Memory consumption is reduced by 1/3
1051 and there are modest speed-ups as well. The API is unchanged.
1052
Tim Petersde7990b2005-07-17 23:45:23 +00001053- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1054
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001055- SF bug #1229429: PyObject_CallMethod failed to decrement some
1056 reference counts in some error exit cases.
1057
Tim Petersecc6e6a2005-07-10 22:30:55 +00001058- SF bug #1185883: Python's small-object memory allocator took over
1059 a block managed by the platform C library whenever a realloc specified
1060 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001061 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001062 portable way to copy data from the C-managed block into Python's
1063 small-object space without risking a memory fault. Python's small-object
1064 realloc now leaves such blocks under the control of the platform C
1065 realloc.
1066
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001067- SF bug #1232517: An overflow error was not detected properly when
1068 attempting to convert a large float to an int in os.utime().
1069
Raymond Hettinger3296e692005-06-29 23:29:56 +00001070- SF bug #1224347: hex longs now print with lowercase letters just
1071 like their int counterparts.
1072
Michael W. Hudson188d4362005-06-20 16:52:57 +00001073- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1074 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1075 interpreter states; back out that fix and do a better job (see
1076 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1077 for a longer write-up of the problem).
1078
Michael W. Hudsondf888462005-06-03 14:41:55 +00001079- SF patch #1180995: marshal now uses a binary format by default when
1080 serializing floats.
1081
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001082- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1083 the routines that promise to produce IEEE 754 binary representations
1084 of floats now simply copy bytes around.
1085
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001086- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1087 278.
1088
Brett Cannonc3647ac2005-04-26 03:45:26 +00001089- patch #1109424: int, long, float, complex, and unicode now check for the
1090 proper magic slot for type conversions when subclassed. Previously the
1091 magic slot was ignored during conversion. Semantics now match the way
1092 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001093 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001094 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001095 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001096
Barry Warsawc8d907c2005-04-19 23:43:40 +00001097- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1098 NULL, now raise an AttributeError when attempting to set or delete the
1099 attribute. Previously a TypeError was raised, but this was inconsistent
1100 with the equivalent pure-Python implementation.
1101
Michael W. Hudson774479c2005-04-18 08:46:17 +00001102- It is now safe to call PyGILState_Release() before
1103 PyEval_InitThreads() (note that if there is reason to believe there
1104 are multiple threads around you still must call PyEval_InitThreads()
1105 before using the Python API; this fix is for extension modules that
1106 have no way of knowing if Python is multi-threaded yet).
1107
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001108- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1109 disabled caused a crash.
1110
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001111- Bug #1165306: instancemethod_new allowed the creation of a method
1112 with im_class == im_self == NULL, which caused a crash when called.
1113
Tim Petersecc6e6a2005-07-10 22:30:55 +00001114- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001115 fixes the crash seen in bug #1165761
1116
Raymond Hettinger96229b12005-03-11 06:49:40 +00001117- Added two new builtins, any() and all().
1118
Brett Cannon409d8f22005-03-05 06:47:57 +00001119- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001120 (e.g., ``class C(): pass`` is no longer a syntax error).
1121 Patch #1176012 added support to the 'parser' module and 'compiler' package
1122 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001123
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001124- Patch #1115086: Support PY_LONGLONG in structmember.
1125
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001126- Bug #1155938: new style classes did not check that __init__() was
1127 returning None.
1128
Tim Petersecc6e6a2005-07-10 22:30:55 +00001129- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001130 ('\') with a specific error message.
1131
Martin v. Löwisff232d72005-03-03 09:24:38 +00001132- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1133
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001134- Bug #1124295: the __name__ attribute of file objects was
1135 inadvertently made inaccessible in restricted mode.
1136
Tim Petersecc6e6a2005-07-10 22:30:55 +00001137- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001138 an ferror() call.
1139
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001140- min() and max() now support key= arguments with the same meaning as in
1141 list.sort().
1142
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001143- The peephole optimizer now performs simple constant folding in expressions:
1144 (2+3) --> (5).
1145
Raymond Hettingera422c342005-01-11 03:03:27 +00001146- set and frozenset objects can now be marshalled. SF #1098985.
1147
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001148- Bug #1077106: Poor argument checking could cause memory corruption
1149 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001150
Jeremy Hyltonab630502005-02-04 18:44:06 +00001151- The parser did not complain about future statements in illegal
1152 positions. It once again reports a syntax error if a future
1153 statement occurs after anything other than a doc string.
1154
Neil Schemenauercf52c072005-08-12 17:34:58 +00001155- Change the %s format specifier for str objects so that it returns a
1156 unicode instance if the argument is not an instance of basestring and
1157 calling __str__ on the argument returns a unicode instance.
1158
Tim Petersf4e69282006-02-27 17:15:31 +00001159- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1160 current thread state when the auto-GIL-state machinery knows about
1161 it (since the thread state is being deleted, continuing to remember it
1162 can't help, but can hurt if another thread happens to get created with
1163 the same thread id).
1164
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001165Extension Modules
1166-----------------
1167
Georg Brandl43f08a82006-03-31 18:01:16 +00001168- Patch #1380952: fix SSL objects timing out on consecutive read()s
1169
Neal Norwitz05a45592006-03-20 06:30:08 +00001170- Patch #1309579: wait3 and wait4 were added to the posix module.
1171
Anthony Baxterfa869072006-03-20 05:21:58 +00001172- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1173 In addition, the existing ulaw code was updated.
1174
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001175- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001176 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001177
Neal Norwitz10be10c2006-03-16 06:50:13 +00001178- Everything under lib-old was removed. This includes the following modules:
1179 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001180 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001181 util, whatsound, whrandom, zmod
1182
1183- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1184
1185- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001186 is deprecated. The undocumented re.engine variable no longer exists.
1187
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001188- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1189 SS2 (single-shift 2) escape sequences correctly.
1190

1194
Neal Norwitzb62c4332006-03-04 18:35:47 +00001195- The timing module is no longer built by default. It was deprecated

1296 the request code argument, which results in more C-like behaviour
1297 for large or negative values.
1298
Tim Petersecc6e6a2005-07-10 22:30:55 +00001299- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

1341
Raymond Hettingerb2594052004-12-05 09:25:51 +00001342- itertools.islice() now accepts None for the start and step arguments.
1343 This allows islice() to work more readily with slices:
1344 islice(s.start, s.stop, s.step)
1345
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001346- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001355- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1356 been renamed to have only a single underscore prefix. This was done to
1357 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001358
Nick Coghlan43832302006-04-23 17:04:07 +00001359- PEP 338: new module runpy defines a run_module function to support
1360 executing modules which provide access to source code or a code object
1361 via the PEP 302 import mechanisms.
1362
Anthony Baxter93f5b932006-04-03 08:05:07 +00001363- The email module's parsedate_tz function now sets the daylight savings

1371 in attribute values.
1372
Anthony Baxterc51ee692006-04-01 00:57:31 +00001373- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001374 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001375 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001376 module will not be built.
1377
Tim Petersc17976e2006-04-01 00:26:53 +00001378- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1379 aren't officially supported here, and trying to use them will probably
1380 raise an exception some day. But dicts have been allowed, and "mostly
1381 worked", so support for them won't go away without warning.
1382
Georg Brandl338ef7d2006-03-31 18:42:16 +00001383- Bug #1445068: getpass.getpass() can now be given an explicit stream
1384 argument to specify where to write the prompt.
1385

1401
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001402- email 4.0 package now integrated. This is largely the same as the email 3.0
1403 package that was included in Python 2.3, except that PEP 8 module names are
1404 now used (e.g. mail.message instead of email.Message). The MIME classes
1405 have been moved to a subpackage (e.g. email.mime.text instead of
1406 email.MIMEText). The old names are still supported for now. Several
1407 deprecated Message methods have been removed and lots of bugs have been
1408 fixed. More details can be found in the email package documentation.
1409
Walter Dörwald40108c92006-03-27 08:15:44 +00001410- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1411 (a subclass of tuple) that provides incremental decoders and encoders
1412 (a way to use stateful codecs without the stream API). Python functions
1413 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1414 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1415 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001417- Patch #1359365: Calling next() on a closed StringIO.String object raises
1418 a ValueError instead of a StopIteration now (like file and cString.String do).
1419 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1420 called before (like file and StringIO.StringIO do).

1488
Neal Norwitz338e7862005-12-23 21:27:46 +00001489- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
1490 LoadError as documented, instead of IOError. For compatibility,
1491 LoadError subclasses IOError.
1492
Brett Cannon3cbd0382005-12-16 22:49:23 +00001493- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001494 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1495 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1496 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1497 Ronald L. Rivest offered this advice for Python:
1498
1499 "The consensus of researchers in this area (at least as
1500 expressed at the NIST Hash Function Workshop 10/31/05),
1501 is that SHA-256 is a good choice for the time being, but
1502 that research should continue, and other alternatives may
1503 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001504
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001505- Added a subset of Fredrik Lundh's ElementTree package. Available

1558 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001559 correct line numbers for decoding errors in source code.

1598 Bug #1224621.
1599
Raymond Hettinger68c04532005-06-10 11:05:19 +00001600- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001601 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001602 the generate_tokens() function now accepts a callable argument that
1603 terminates by raising StopIteration.
1604

1622 instead of raising a TypeError when interacting with other types. This
1623 allows other classes to implement __radd__ style methods and have them
1624 work as expected.
1625
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001626- Bug #1163325: Decimal infinities failed to hash. Attempting to

Guido van Rossumd0641422005-02-03 15:01:24 +00001664- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1665 disables recursive traversal through instance attributes, which can
1666 be exploited in various ways.
1667
Tim Peterse3547fd2005-12-16 23:13:57 +00001668- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec

1682
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001683- Enhancements to the csv module:
1684
1685 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001686 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001687 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001688 + Dialect parameter parsing has been re-implemented to improve error
1689 reporting.
1690 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1691 dictates.
1692 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001693 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001694 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001695 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1696 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001697 + reader now allows \r characters to be quoted (previously it only allowed
1698 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001699 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001700 + Dialect classes passed to the module are no longer instantiated by
1701 the module before being parsed (the former validation scheme required
1702 this, but the mechanism was unreliable).
1703 + The dialect registry now contains instances of the internal
1704 C-coded dialect type, rather than references to python objects.
1705 + the internal c-coded dialect type is now immutable.
1706 + register_dialect now accepts the same keyword dialect specifications
1707 as the reader and writer, allowing the user to register dialects
1708 without first creating a dialect class.
1709 + a configurable limit to the size of parsed fields has been added -
1710 previously, an unmatched quote character could result in the entire
1711 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001712 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001713 the parser field size limit (returning the former limit). The initial
1714 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001715 + A line_num attribute has been added to the reader object, which tracks
1716 the number of lines read from the source iterator. This is not
1717 the same as the number of records returned, as records can span
1718 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001719 + reader and writer objects were not being registered with the cyclic-GC.
1720 This has been fixed.
1721
Brett Cannone6539c42005-01-08 02:43:53 +00001722- _DummyThread objects in the threading module now delete self.__block that is
1723 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1724 lock primitives tend to be limited in number and thus should not be wasted on
1725 a _DummyThread object. Fixes bug #1089632.
1726
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001727- The imghdr module now detects Exif files.
1728
Raymond Hettinger6065d322004-12-20 23:51:53 +00001729- StringIO.truncate() now correctly adjusts the size attribute.
1730 (Bug #951915).
1731
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001732- locale.py now uses an updated locale alias table (built using
1733 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1734 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001735 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001736
Raymond Hettinger3557f422004-12-07 12:02:02 +00001737- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1738
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001739- the pickle module no longer accepts the deprecated None option in the
1740 args tuple returned by __reduce__().
1741
Brett Cannon84667c02004-12-07 03:25:18 +00001742- optparse now optionally imports gettext. This allows its use in setup.py.
1743
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001744- the pickle module no longer uses the deprecated bin parameter.
1745
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001746- the shelve module no longer uses the deprecated binary parameter.
1747

1749
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001750- the filecmp module no longer uses the deprecated use_statcache argument.
1751
Raymond Hettinger664347b2004-12-04 21:21:53 +00001752- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1753 extended or overridden by subclasses. Formerly, the subclassed method would
1754 be ignored by the rest of the module. (Bug #1078905).
1755
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001756- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001757 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001758
Walter Dörwald36733692004-12-22 12:50:50 +00001759- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1760 once when a size argument is given. This prevents a buffer overflow in the
1761 tokenizer with very long source lines.
1762
Barry Warsaw538561e2006-01-01 21:48:54 +00001763- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1764 immediately after creating the object, without any intervening
1765 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001766
Skip Montanaro05885812005-01-16 20:48:27 +00001767- The reconvert.quote function can now emit triple-quoted strings. The
1768 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001769
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001770- ``UserString.MutableString`` now supports negative indices in
1771 ``__setitem__`` and ``__delitem__``
1772
Greg Ward40407942005-03-05 02:53:17 +00001773- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1774 correctly.
1775
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001776- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1777 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1778 character even if the user has passed a size parameter to get a proper
1779 line ending. Remove the special handling of a "\r\n" that has been split
1780 between two lines.
1781
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001782- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1783 about illegal code points. The codec now supports PEP 293 style error
1784 handlers.
1785
Walter Dörwald78a78b02005-09-01 12:04:29 +00001786- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001787 from the input stream, so that the output is a byte string in the correct
1788 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001789
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001790- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1791 considering it exactly like a '*'.
1792
Walter Dörwald007f8df2005-10-09 19:42:27 +00001793- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1794 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001795
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001796- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1797
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001798- Patch #1413711: Certain patterns of differences were making difflib
1799 touch the recursion limit.
1800
Walter Dörwald58917a62006-03-31 15:26:22 +00001801- Bug #947906: An object oriented interface has been added to the calendar
1802 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001803 called as a script (e.g. via ``python -mcalendar``). Localized month and
1804 weekday names can be ouput (even if an exotic encoding is used) using
1805 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001806
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001807Build
1808-----
1809
Neal Norwitz602d3392006-03-31 08:21:40 +00001810- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1811 by using -mieee gcc option.
1812
Martin v. Löwis86d66262006-02-17 08:40:11 +00001813- Patch #1432345: Make python compile on DragonFly.
1814
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001815- Build support for Win64-AMD64 was added.
1816
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001817- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1818
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001819- Patch #881820: look for openpty and forkpty also in libbsd.
1820
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001821- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1822 The zlib module is now builtin on Windows.
1823
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001824- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1825
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001826- Bug #1189330: configure did not correctly determine the necessary
1827 value of LINKCC if python was built with GCC 4.0.
1828
Trent Mick8321b422005-07-26 02:29:21 +00001829- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1830 vulnerability in zlib 1.2.1 and 1.2.2.
1831
Brett Cannon08cd5982005-04-24 22:26:38 +00001832- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1833 flags that change binary compatibility. Changes were also made to
1834 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001835 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001836
Bob Ippolitoed233462005-03-29 13:47:59 +00001837- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1838 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1839 no longer exists). This configure patch makes things right.
1840
Martin v. Löwise2713be2005-03-08 15:03:08 +00001841- Bug #1158607: Build with --disable-unicode again.
1842
Brett Cannon46d96232005-02-16 00:07:19 +00001843- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1844 defined. Discovered as a result of not being able to build on OS X.
1845
Brett Cannon516592f2004-12-07 00:42:59 +00001846- setup.py now uses the directories specified in LDFLAGS using the -L option
1847 and in CPPFLAGS using the -I option for adding library and include
1848 directories, respectively, for compiling extension modules against. This has
1849 led to the core being compiled using the values in CPPFLAGS. It also removes
1850 the need for the special-casing of both DarwinPorts and Fink for darwin since
1851 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1852 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1853 Fink, ``-I/opt/local/include`` for DarwinPorts).
1854
Brett Cannon43802422005-02-10 20:48:03 +00001855- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1856 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1857 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1858 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001860C API
1861-----
1862
Tim Petersc9d78aa2006-03-26 23:27:58 +00001863- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1864 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1865 is obtained via the ``PyObject_`` family, it must be released via the
1866 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1867 always been officially true, but when Python's small-object allocator was
1868 introduced, an attempt was made to cater to a few extension modules
1869 discovered at the time that obtained memory via ``PyObject_New`` but
1870 released it via ``PyMem_DEL``. It's years later, and if such code still
1871 exists it will fail now (probably with segfaults, but calling wrong
1872 low-level memory management functions can yield many symptoms).
1873
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001874- Added a C API for set and frozenset objects.
1875
Raymond Hettinger66517482004-12-03 11:45:13 +00001876- Removed PyRange_New().
1877
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001878- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1879 mapping argument now. This string is used as a mapping table. Byte values
1880 greater than the length of the string and 0xFFFE are treated as undefined
1881 mappings.
