16 on each iteration. Fixing this problem required changing the .pyc
17 magic number. This means that .pyc files generated before 2.5c1

Fred Drake53912162006-07-29 13:22:49 +000044What's New in Python 2.5 beta 3?
45================================
Neal Norwitza1f10902006-07-12 07:28:29 +000046
Anthony Baxter5d32a9f2006-08-02 07:43:09 +000047*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +000048
49Core and builtins
50-----------------
51
Neal Norwitzc5e060d2006-08-02 06:14:22 +000052- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t, it previously
53 returned a long (see PEP 353).
54
Neal Norwitzf71ec5a2006-07-30 06:57:04 +000055- Bug #1515471: string.replace() accepts character buffers again.
56
Neal Norwitz07aadb12006-07-30 06:55:48 +000057- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
58 This provides the proper warning for struct.pack().
59 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
60
Neal Norwitz0d62a062006-07-30 06:53:31 +000061- Patch #1531113: Fix augmented assignment with yield expressions.
62 Also fix a SystemError when trying to assign to yield expressions.
63
Phillip J. Ebyf7575d02006-07-28 21:12:07 +000064- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
65 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
66 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
67 excessive filesystem operations during imports.
68
Tim Petersbc24eee2006-07-27 01:14:53 +000069- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
70 operations on signed longs that are formally undefined by C.
71 Unfortunately, at least one compiler now cares about that, so complicated
72 the code to make that compiler happy again.
73
Martin v. Löwis982e9fe2006-07-24 12:54:17 +000074- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
75
Martin v. Löwisd22968a2006-07-24 11:54:53 +000076- Patch #1232023: Stop including current directory in search
77 path on Windows.
78
Neal Norwitze1fdb322006-07-21 05:32:28 +000079- Fix some potential crashes found with failmalloc.
80
Neal Norwitze7563102006-07-17 01:00:16 +000081- Fix warnings reported by Klocwork's static analysis tool.
82
Neal Norwitz84be93b2006-07-16 01:50:38 +000083- Bug #1512814, Fix incorrect lineno's when code within a function
84 had more than 255 blank lines.
85
Georg Brandl9dceedb2006-07-12 15:31:17 +000086- Patch #1521179: Python now accepts the standard options ``--help`` and
87 ``--version`` as well as ``/?`` on Windows.
88
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +000089- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +000090 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +000091 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +000092
Tim Peters112aad32006-07-19 00:03:19 +000093- Bug #1524317: Compiling Python ``--without-threads`` failed.
94 The Python core compiles again then, and, in a build without threads, the
95 new ``sys._current_frames()`` returns a dictionary with one entry,
96 mapping the faux "thread id" 0 to the current frame.
97
Ronald Oussoren3075e162006-07-25 20:28:55 +000098- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +000099
Ronald Oussoren3075e162006-07-25 20:28:55 +0000100
Neal Norwitza1f10902006-07-12 07:28:29 +0000101Library
102-------
103
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000104- Correction of patch #1455898: In the mbcs decoder, set final=False
105 for stream decoder, but final=True for the decode function.
106
Georg Brandl07fec3a2006-08-01 18:49:24 +0000107- os.urandom no longer masks unrelated exceptions like SystemExit or
108 KeyboardInterrupt.
109
Martin v. Löwis4e678382006-07-30 13:00:31 +0000110- Bug #1525866: Don't copy directory stat times in
111 shutil.copytree on Windows
112
Georg Brandle34ac7c2006-07-30 11:07:23 +0000113- Bug #1002398: The documentation for os.path.sameopenfile now correctly
114 refers to file descriptors, not file objects.
115
Fred Drakefbdeaad2006-07-29 16:56:15 +0000116- Rename of the xml package to xmlcore, and the import hackery done to
117 make it appear at both names, has been removed. Bug #1511497,
118 #1513611, and probably others.
119
Georg Brandledd9b0d2006-07-29 09:33:26 +0000120- Bug #1441397: The compiler module now recognizes module and function
121 docstrings correctly as it did in Python 2.4.
122
Tim Peters6f681472006-07-27 23:44:37 +0000123- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
124 lost that tests are sorted by name before being run. This rarely
125 matters for well-written tests, but can create baffling symptoms if
126 side effects from one test to the next affect outcomes. ``DocTestFinder``
127 has been changed to sort the list of tests it returns.
128
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000129- The distutils version has been changed to 2.5.0, and are now kept
130 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000131
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000132- Bug #978833: Really close underlying socket in _socketobject.close.
133
Georg Brandl0619a322006-07-26 07:40:17 +0000134- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
135 with title().
136
Georg Brandlcf0c1722006-07-26 07:23:32 +0000137- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
138 to recursive calls and call it with the failing package name.
139
Martin v. Löwis0b483032006-07-25 09:53:12 +0000140- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
141
Georg Brandlc13c34c2006-07-24 14:09:56 +0000142- Patch #1515343: Fix printing of deprecated string exceptions with a
143 value in the traceback module.
144
Greg Ward48fae7a2006-07-23 16:05:51 +0000145- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
146
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000147- Patch #1524429: Use repr() instead of backticks in Tkinter again.
148
Brett Cannoncaebe222006-07-18 04:41:36 +0000149- Bug #1520914: Change time.strftime() to accept a zero for any position in its
150 argument tuple. For arguments where zero is illegal, the value is forced to
151 the minimum value that is correct. This is to support an undocumented but
152 common way people used to fill in inconsequential information in the time
153 tuple pre-2.4.
154
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000155- Patch #1220874: Update the binhex module for Mach-O.
156
Barry Warsawb110bad2006-07-21 14:51:07 +0000157- The email package has improved RFC 2231 support, specifically for
158 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
159 (name*0=<blah>) parameter continuations. This may change the types of
160 values returned from email.message.Message.get_param() and friends.
161 Specifically in some cases where non-encoded continuations were used,
162 get_param() used to return a 3-tuple of (None, None, string) whereas now it
163 will just return the string (since non-encoded continuations don't have
164 charset and language parts).
165
166 Also, whereas % values were decoded in all parameter continuations, they are
167 now only decoded in encoded parameter parts.
168
Ronald Oussoren3075e162006-07-25 20:28:55 +0000169- Bug #1517990: IDLE keybindings on MacOS X now work correctly
170
171- Bug #1517996: IDLE now longer shows the default Tk menu when a
172 path browser, class browser or debugger is the frontmost window on MacOS X
173
Barry Warsaw00decd72006-07-27 23:43:15 +0000174- Patch #1520294: Support for getset and member descriptors in types.py,
175 inspect.py, and pydoc.py. Specifically, this allows for querying the type
176 of an object against these built-in types and more importantly, for getting
177 their docstrings printed in the interactive interpreter's help() function.

181-----------------
182
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000183- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
184 a socket operation on a socket with a timeout, the exception will be
185 caught correctly. Previously, the exception was not caught.
186
Thomas Heller1393d6a2006-07-28 21:43:20 +0000187- Patch #1529514: The _ctypes extension is now compiled on more
188 openbsd target platforms.
189
Tim Peters9cab5932006-07-28 00:30:00 +0000190- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
191 a memory leak, affecting pickles and deep copies.
192
Tim Petersbc24eee2006-07-27 01:14:53 +0000193- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000194 Paul Eggert.
195
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000196- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
197
Thomas Hellerce049a02006-07-14 17:51:14 +0000198- Patch #1521817: Index range checking on ctypes arrays containing
199 exactly one element enabled again. This allows iterating over these
200 arrays, without the need to check the array size before.
201
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000202- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000203 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000204 /dev/null in certain cases; this is now fixed.
205
Thomas Heller47d7a062006-07-12 08:43:47 +0000206- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
207 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000208
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000209- Because of a misspelled preprocessor symbol, ctypes was always
210 compiled without thread support; this is now fixed.
211
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000212- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
213 methods now allow their database parameter to be None as the
214 sleepycat API allows.
215
Matt Flemingec926502006-07-28 11:27:27 +0000216- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
217 bluetooth API compared with Linux and FreeBSD.
218
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000219Tests
220-----
221
222- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
223 how long the test file should take to play. Now accepts taking 2.93 secs
224 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
225
Georg Brandl4793aa32006-07-28 18:31:39 +0000226- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
227 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
228 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000229

Ronald Oussoren26cad082006-08-01 21:00:57 +0000235Mac
236---
237
238- PythonLauncher now works correctly when the path to the script contains
239 characters that are treated specially by the shell (such as quotes).
240
241- Bug #1527397: PythonLauncher now launches scripts with the working directory
242 set to the directory that contains the script instead of the user home
243 directory. That latter was an implementation accident and not what users
244 expect.

253-----------------
254
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000255- Bug #1441486: The literal representation of -(sys.maxint - 1)
256 again evaluates to a int object, not a long.
257
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000258- Bug #1501934: The scope of global variables that are locally assigned
259 using augmented assignment is now correctly determined.
260
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000261- Bug #927248: Recursive method-wrapper objects can now safely
262 be released.
263
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000264- Bug #1417699: Reject locale-specific decimal point in float()
265 and atof().
266
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000267- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
268 omit a default "error" argument for NULL pointer. This allows
269 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000270
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000271- Bug #1519018: 'as' is now validated properly in import statements.
272
Neal Norwitz28746ab2006-07-09 22:14:42 +0000273- On 64 bit systems, int literals that use less than 64 bits are
274 now ints rather than longs.
275
Neal Norwitzed657552006-07-10 00:04:44 +0000276- Bug #1512814, Fix incorrect lineno's when code at module scope
277 started after line 256.
278
Tim Peters32a83612006-07-10 21:08:24 +0000279- New function ``sys._current_frames()`` returns a dict mapping thread
280 id to topmost thread stack frame. This is for expert use, and is
281 especially useful for debugging application deadlocks. The functionality
282 was previously available in Fazal Majid's ``threadframe`` extension
283 module, but it wasn't possible to do this in a wholly threadsafe way from
284 an extension.

Thomas Woutersadd19112006-07-05 11:03:49 +0000302- string.Template() now correctly handles tuple-values. Previously,
303 multi-value tuples would raise an exception and single-value tuples would
304 be treated as the value they contain, instead.
305
Martin v. Löwisede77f52006-07-03 13:01:35 +0000306- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

331
Brett Cannon53ab5b72006-06-22 16:49:14 +0000332- Bug #1510580: The 'warnings' module improperly required that a Warning
333 category be either a types.ClassType and a subclass of Warning. The proper
334 check is just that it is a subclass with Warning as the documentation states.
335
Georg Brandlad29e632006-06-21 17:45:17 +0000336- The compiler module now correctly compiles the new try-except-finally
337 statement (bug #1509132).

343
Gerhard Häring762fbd32006-07-02 17:48:30 +0000344- The sqlite3 module did cut off data from the SQLite database at the first
345 null character before sending it to a custom converter. This has been fixed
346 now.

Tim Peters112aad32006-07-19 00:03:19 +0000351- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
352 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
353 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000354
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000355- Assigning None to pointer type fields in ctypes structures possible
356 overwrote the wrong fields, this is fixed now.
357
358- Fixed a segfault in _ctypes when ctypes.wintypes were imported
359 on non-Windows platforms.
360
361- Bug #1518190: The ctypes.c_void_p constructor now accepts any
362 integer or long, without range checking.
363
364- Patch #1517790: It is now possible to use custom objects in the ctypes
365 foreign function argtypes sequence as long as they provide a from_param
366 method, no longer is it required that the object is a ctypes type.
367
368- The '_ctypes' extension module now works when Python is configured
369 with the --without-threads option.
370
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000371- Bug #1513646: os.access on Windows now correctly determines write
372 access, again.
373
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000374- Bug #1512695: cPickle.loads could crash if it was interrupted with
375 a KeyboardInterrupt.
376
Neal Norwitza12aa882006-07-06 06:45:08 +0000377- Bug #1296433: parsing XML with a non-default encoding and
378 a CharacterDataHandler could crash the interpreter in pyexpat.
379

386
Tim Peters32a83612006-07-10 21:08:24 +0000387- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000388 Previously, the slight difference could cause compilation errors of the
389 'zlib' module on systems with more than one version of zlib.
390
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000391- The MSI compileall step was fixed to also support a TARGETDIR
392 with spaces in it.
393

421Core and builtins
422-----------------
423
Georg Brandla56b9152006-06-19 06:35:54 +0000424- Patch #1507676: Error messages returned by invalid abstract object operations
425 (such as iterating over an integer) have been improved and now include the
426 type of the offending object to help with debugging.
427
Brett Cannonea3912b2006-06-13 21:46:41 +0000428- Bug #992017: A classic class that defined a __coerce__() method that returned
429 its arguments swapped would infinitely recurse and segfault the interpreter.
430
Neal Norwitz909eb122006-06-12 02:13:21 +0000431- Fix the socket tests so they can be run concurrently.
432
Neal Norwitzb9845e72006-06-12 02:11:18 +0000433- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000434 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000435
Brett Cannon22565aa2006-06-09 22:31:23 +0000436- Bug #532646: object.__call__() will continue looking for the __call__
437 attribute on objects until one without one is found. This leads to recursion
438 when you take a class and set its __call__ attribute to an instance of the
439 class. Originally fixed for classic classes, but this fix is for new-style.
440 Removes the infinite_rec_3 crasher.
441
Georg Brandl24250812006-06-09 18:45:48 +0000442- The string and unicode methods startswith() and endswith() now accept
443 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
444
Brett Cannonde3b0522006-06-08 17:00:45 +0000445- Buffer objects, at the C level, never used the char buffer
446 implementation even when the char buffer for the wrapped object was
447 explicitly requested (originally returned the read or write buffer).
448 Now a TypeError is raised if the char buffer is not present but is
449 requested.
450
Georg Brandlddbaa662006-06-04 21:56:52 +0000451- Patch #1346214: Statements like "if 0: suite" are now again optimized
452 away like they were in Python 2.4.
453
Georg Brandlb7c8f542006-05-27 12:30:25 +0000454- Builtin exceptions are now full-blown new-style classes instead of
455 instances pretending to be classes, which speeds up exception handling
456 by about 80% in comparison to 2.5a2.
457
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000458- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
459 Unicode 4.1.
460
Georg Brandlf4ef1162006-05-26 18:03:31 +0000461- Patch #921466: sys.path_importer_cache is now used to cache valid and
462 invalid file paths for the built-in import machinery which leads to
463 fewer open calls on startup.
464
Tim Peters696cf432006-05-24 21:10:40 +0000465- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
466 of-2 bases. The largest speedup is for inputs with about 1000 decimal
467 digits. Conversion from non-power-of-2 bases remains quadratic-time in
468 the number of input digits (it was and remains linear-time for bases
469 2, 4, 8, 16 and 32).
470
Tim Petersb713ec22006-05-23 18:45:30 +0000471- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
472 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
473 an integer close to ``sys.maxint``. This was repaired by patch
474 #1335972, which also gives a nice speedup.
475
Richard Jonescebbefc2006-05-23 18:28:17 +0000476- Patch #1337051: reduced size of frame objects.
477
478- PyErr_NewException now accepts a tuple of base classes as its
479 "base" parameter.
480
Richard Jones7c88dcc2006-05-23 10:37:38 +0000481- Patch #876206: function call speedup by retaining allocated frame
482 objects.
483
Georg Brandl7b90e162006-05-18 07:01:27 +0000484- Bug #1462152: file() now checks more thoroughly for invalid mode
485 strings and removes a possible "U" before passing the mode to the
486 C library function.
487
Neal Norwitz1004a532006-05-15 07:17:23 +0000488- Patch #1488312, Fix memory alignment problem on SPARC in unicode
489
Neal Norwitz373f0a72006-05-15 07:04:36 +0000490- Bug #1487966: Fix SystemError with conditional expression in assignment
491
Martin v. Löwis879768d2006-05-11 13:28:43 +0000492- WindowsError now has two error code attributes: errno, which carries
493 the error values from errno.h, and winerror, which carries the error
494 values from winerror.h. Previous versions put the winerror.h values
495 (from GetLastError()) into the errno attribute.
496
Martin v. Löwis77736712006-05-04 05:51:03 +0000497- Patch #1475845: Raise IndentationError for unexpected indent.
498
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000499- Patch #1479181: split open() and file() from being aliases for each other.
500
Tim Peters44bd9862006-06-01 13:49:23 +0000501- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
502 methods were always silently ignored by dictionaries when comparing keys.
503 They are now passed through (except when using the C API function
504 ``PyDict_GetItem()``, whose semantics did not change).
505
506- Bug #1456209: In some obscure cases it was possible for a class with a
507 custom ``__eq__()`` method to confuse dict internals when class instances
508 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
509 No, you don't have any code that did this ;-)

Brett Cannon6ee7d012006-06-08 16:23:04 +0000518- Change binascii.hexlify to accept a read-only buffer instead of only a char
519 buffer and actually follow its documentation.
520
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000521- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
522
Nick Coghlanc649ec52006-05-29 12:43:05 +0000523- Patch #1478788 (modified version): The functional extension module has
524 been renamed to _functools and a functools Python wrapper module added.
525 This provides a home for additional function related utilities that are
526 not specifically about functional programming. See PEP 309.
527
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000528- Patch #1493701: performance enhancements for struct module.

534
Andrew MacIntyre92913322006-06-13 15:04:24 +0000535- Patch #1454481: thread stack size is now tunable at runtime for thread
536 enabled builds on Windows and systems with Posix threads support.
537
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000538- On Win32, os.listdir now supports arbitrarily-long Unicode path names
539 (up to the system limit of 32K characters).
540
541- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
542 As a result, these functions now raise WindowsError instead of OSError.
543
Tim Peters7a822da2006-05-25 21:50:17 +0000544- ``time.clock()`` on Win64 should use the high-performance Windows
545 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
546 Windows platforms).
547
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000548- Calling Tk_Init twice is refused if the first call failed as that
549 may deadlock.
550
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000551- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
552 accept it without potentially using an uninitialized pointer.
553
554- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
555 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

562 parameter is supplied. [SF pybsddb bug #1477863]
563
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000564- bsddb: the __len__ method of a DB object has been fixed to return correct
565 results. It could previously incorrectly return 0 in some cases.

567
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000568- bsddb: the bsddb.dbtables Modify method now raises the proper error and
569 aborts the db transaction safely when a modifier callback fails.

571
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000572- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000573 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000574 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
575 database calls that would previously deadlock. [SF python bug #775414]

605 double-byte encodings.
606
Tim Peters43898b42006-06-14 04:09:25 +0000607- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
608 guarantee that adjacent triples in the return list always describe
609 non-adjacent blocks. Previously, a pair of matching blocks could end
610 up being described by multiple adjacent triples that formed a partition
611 of the matching pair.
612
Greg Ward0e0c9f42006-06-11 16:24:11 +0000613- Bug #1498146: fix optparse to handle Unicode strings in option help,

Nick Coghlan676725d2006-06-08 13:54:49 +0000623- The functions update_wrapper() and wraps() have been added to the functools
624 module. These make it easier to copy relevant metadata from the original
625 function when writing wrapper functions.
626
Tim Petersd6a9eef2006-06-05 01:48:21 +0000627- The optional ``isprivate`` argument to ``doctest.testmod()``, and the

Martin v. Löwis3f767792006-06-04 19:36:28 +0000630- Patch #1359618: Speed up charmap encoder by using a trie structure
631 for lookup.
632
Tim Petersd609b1a2006-06-02 23:22:51 +0000633- The functions in the ``pprint`` module now sort dictionaries by key
634 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
635 if and only if its display required more than one line, although that
636 wasn't documented. The new behavior increases predictability; e.g.,
637 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
638
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000639- Patch #1497027: try HTTP digest auth before basic auth in urllib2
640 (thanks for J. J. Lee).
641
Georg Brandl2b330372006-05-28 20:23:12 +0000642- Patch #1496206: improve urllib2 handling of passwords with respect to
643 default HTTP and HTTPS ports.
644
George Yoshidaf3c65de2006-05-28 16:39:09 +0000645- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
646
Bob Ippolito7298f272006-05-23 18:43:47 +0000647- Patch #1281707: speed up gzip.readline.
648
Georg Brandlb89316f2006-05-17 15:51:16 +0000649- Patch #1180296: Two new functions were added to the locale module:
650 format_string() to get the effect of "format % items" but locale-aware,
651 and currency() to format a monetary number with currency sign.
652
Georg Brandle3a25832006-05-17 14:56:04 +0000653- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
654 and several features added, such as speed and geometry control.
655
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000656- Patch #1488881: add support for external file objects in bz2 compressed
657 tarfiles.
658
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000659- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
660 stdout arguments, making it possible to redirect input and output
661 for remote debugging.
662
663- Patch #1484695: Update the tarfile module to version 0.8. This fixes
664 a couple of issues, notably handling of long file names using the
665 GNU LONGNAME extension.
666
667- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
668 new flag when ``name`` is already the name of an option flag.
669
670- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
671 package.
672
673- Patch #1472854: make the rlcompleter.Completer class usable on non-
674 UNIX platforms.
675
676- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
677
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000678- Bug #1472827: correctly escape newlines and tabs in attribute values in
679 the saxutils.XMLGenerator class.

708
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000709What's New in Python 2.5 alpha 2?
710=================================
711
712*Release date: 27-APR-2006*
713
714Core and builtins
715-----------------
716
Thomas Heller1b046642006-04-18 18:51:06 +0000717- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
718 by converting these apis from macros into exported functions again:
719
720 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
721 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
722 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
723 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
724 PyRun_String Py_CompileString
725
Martin v. Löwis45294a92006-04-18 06:24:08 +0000726- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
727
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000728- All uses of PyStructSequence_InitType have been changed to initialize
729 the type objects only once, even if the interpreter is initialized
730 multiple times.
731
Neal Norwitz61546162006-04-14 05:20:28 +0000732- Bug #1454485, array.array('u') could crash the interpreter. This was
733 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
734 to unicode when it didn't make sense. 'u#' now requires a unicode string.
735
736- Py_UNICODE is unsigned. It was always documented as unsigned, but
737 due to a bug had a signed value in previous versions.
738
Tim Peters3a5e8b12006-04-11 01:44:07 +0000739- Patch #837242: ``id()`` of any Python object always gives a positive
740 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
741 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000742 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000743 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000744
Tim Peters3a5e8b12006-04-11 01:44:07 +0000745 def __hash__(self):
746 return id(self) # WRONG
747
748 because a hash result must be a (short) Python int but it was always
749 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000750 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000751 was always usable as a hash value before this patch. That's no longer
752 necessarily so.
753
754- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000755 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000756 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000757 #1454844)
758
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000759- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
760 involving generators that have paused outside of any ``try`` or ``with``
761 blocks. (In 2.5a1, a paused generator that was part of a reference
762 cycle could not be garbage collected, regardless of whether it was
763 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000765Extension Modules
766-----------------
767
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000768- Patch #1191065: Fix preprocessor problems on systems where recvfrom
769 is a macro.
770
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000771- Bug #1467952: os.listdir() now correctly raises an error if readdir()
772 fails with an error condition.
773
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000774- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
775
776- Bug #1117761: bsddb.*open() no longer raises an exception when using
777 the cachesize parameter.
778
779- Bug #1149413: bsddb.*open() no longer raises an exception when using
780 a temporary db (file=None) with the 'n' flag to truncate on open.
781
782- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
783 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000784
Armin Rigoa9017c32006-04-19 11:50:27 +0000785- Patch #1062014: AF_UNIX sockets under Linux have a special
786 abstract namespace that is now fully supported.
787
Anthony Baxter51bcb682006-04-05 14:51:42 +0000788Library
789-------
790
Peter Astrand7d1d4362006-07-14 14:04:45 +0000791- Bug #1223937: subprocess.CalledProcessError reports the exit status
792 of the process using the returncode attribute, instead of
793 abusing errno.
794
Tim Peters711bf302006-04-25 03:31:36 +0000795- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
796 a doctest to be skipped (the code is not run, and the expected output
797 or exception is ignored).
798
Nick Coghlanda2268f2006-04-24 04:37:15 +0000799- Fixed contextlib.nested to cope with exceptions being raised and
800 caught inside exit handlers.
801
Greg Wardab05edc2006-04-23 03:47:58 +0000802- Updated optparse module to Optik 1.5.1 (allow numeric constants in
803 hex, octal, or binary; add ``append_const`` action; keep going if
804 gettext cannot be imported; added ``OptionParser.destroy()`` method;
805 added ``epilog`` for better help generation).
806
Tim Peters21fbd572006-04-21 21:18:10 +0000807- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
808 called from a thread spawned as a side effect of importing a module.
809
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000810- The pydoc module now supports documenting packages contained in
811 .zip or .egg files.
812
813- The pkgutil module now has several new utility functions, such
814 as ``walk_packages()`` to support working with packages that are either
815 in the filesystem or zip files.
816
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000817- The mailbox module can now modify and delete messages from
818 mailboxes, in addition to simply reading them. Thanks to Gregory
819 K. Johnson for writing the code, and to the 2005 Google Summer of
820 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000821
Tim Petersc7605f22006-04-17 21:12:33 +0000822- The ``__del__`` method of class ``local`` in module ``_threading_local``
823 returned before accomplishing any of its intended cleanup.
824
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000825- Patch #790710: Add breakpoint command lists in pdb.
826
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000827- Patch #1063914: Add Tkinter.Misc.clipboard_get().
828
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000829- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
830
Anthony Baxtere29002c2006-04-12 12:07:31 +0000831- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
832 Windows. Bug #1469163.
833
Phillip J. Eby47032112006-04-11 01:07:43 +0000834- The warnings, linecache, inspect, traceback, site, and doctest modules
835 were updated to work correctly with modules imported from zipfiles or
836 via other PEP 302 __loader__ objects.
837
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000838- Patch #1467770: Reduce usage of subprocess._active to processes which
839 the application hasn't waited on.
840
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000841- Patch #1462222: Fix Tix.Grid.
842
Neal Norwitza31bf182006-04-09 03:35:43 +0000843- Fix exception when doing glob.glob('anything*/')
844
Skip Montanaro262fb922006-04-21 02:31:07 +0000845- The pstats.Stats class accepts an optional stream keyword argument to
846 direct output to an alternate file-like object.
847

849-----
850
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000851- The Makefile now has a reindent target, which runs reindent.py on
852 the library.
853
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000854- Patch #1470875: Building Python with MS Free Compiler
855
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000856- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000857
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000858- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
859 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000860 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000861 CXX from --with-cxx-main, see description in README.
862
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000863- Patch #1429775: Link extension modules with the shared libpython.
864
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000865- Fixed a libffi build problem on MIPS systems.
866
Tim Peters8931ff12006-05-13 23:28:20 +0000867- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
868 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
869 and "%zu" for unsigned integers of type ``size_t``.
870
Anthony Baxter51bcb682006-04-05 14:51:42 +0000871Tests
872-----
873
Nick Coghlanda2268f2006-04-24 04:37:15 +0000874- test_contextlib now checks contextlib.nested can cope with exceptions
875 being raised and caught inside exit handlers.
876
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000877- test_cmd_line now checks operation of the -m and -c command switches
878
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000879- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
880 it separately and by hand. It also wasn't cleaning up its changes to
881 the current Decimal context.
882
Thomas Woutersabd08882006-04-26 15:53:30 +0000883- regrtest.py now has a -M option to run tests that test the new limits of
884 containers, on 64-bit architectures. Running these tests is only sensible
885 on 64-bit machines with more than two gigabytes of memory. The argument
886 passed is the maximum amount of memory for the tests to use.

895-------------
896
Tim Petersb06d28c2006-05-12 01:57:59 +0000897- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
898
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000899- PEP 343: Added Context Types section to the library reference
900 and attempted to bring other PEP 343 related documentation into
901 line with the implementation and/or python-dev discussions.
902
Tim Peters8dc73d22006-04-24 02:03:16 +0000903- Bug #1337990: clarified that ``doctest`` does not support examples
904 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000907What's New in Python 2.5 alpha 1?
908=================================
909
Anthony Baxterebed3f62006-04-03 15:03:44 +0000910*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000911
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000912Core and builtins
913-----------------
914
Nick Coghlan43832302006-04-23 17:04:07 +0000915- PEP 338: -m command line switch now delegates to runpy.run_module
916 allowing it to support modules in packages and zipfiles
917
Martin v. Löwisc661b882006-04-20 04:54:23 +0000918- On Windows, .DLL is not an accepted file name extension for
919 extension modules anymore; extensions are only found if they
920 end in .PYD.
921
Martin v. Löwisea62d252006-04-03 10:56:49 +0000922- Bug #1421664: sys.stderr.encoding is now set to the same value as
923 sys.stdout.encoding.
924
Neal Norwitz92e212f2006-04-03 04:48:37 +0000925- __import__ accepts keyword arguments.
926
Georg Brandlccadf842006-03-31 18:54:53 +0000927- Patch #1460496: round() now accepts keyword arguments.
928
Anthony Baxter262c00a2006-03-30 10:53:17 +0000929- Fixed bug #1459029 - unicode reprs were double-escaped.
930
Hye-Shik Changd478f342006-03-23 12:32:36 +0000931- Patch #1396919: The system scope threads are reenabled on FreeBSD
932 5.4 and later versions.
933
Neal Norwitze98ccf62006-03-23 05:39:47 +0000934- Bug #1115379: Compiling a Unicode string with an encoding declaration
935 now gives a SyntaxError.
936
Georg Brandlabd1ff82006-03-18 07:59:59 +0000937- Previously, Python code had no easy way to access the contents of a
938 cell object. Now, a ``cell_contents`` attribute has been added
939 (closes patch #1170323).
940
Tim Peterscf79aac2006-03-16 01:14:46 +0000941- Patch #1123430: Python's small-object allocator now returns an arena to
942 the system ``free()`` when all memory within an arena becomes unused
943 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
944 freed. Some applications will see a drop in virtual memory size now,
945 especially long-running applications that, from time to time, temporarily
946 use a large number of small objects. Note that when Python returns an
947 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000948 platform C library will in turn return that memory to the operating system.
949 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000950 appears to be effective at least on Microsoft C and gcc-based systems.
951 Thanks to Evan Jones for hard work and patience.
952
Georg Brandl533ff6f2006-03-08 18:09:27 +0000953- Patch #1434038: property() now uses the getter's docstring if there is
954 no "doc" argument given. This makes it possible to legitimately use
955 property() as a decorator to produce a read-only property.
956
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000957- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
958 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
959 of requiring an int or long in slicing and a few other contexts, enabling
960 other objects (e.g. Numeric Python's integers) to be used as slice indices.
961
Neal Norwitz995acdf2006-03-07 05:01:00 +0000962- Fixed various bugs reported by Coverity's Prevent tool.
963
Brett Cannonbf364092006-03-01 04:25:17 +0000964- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
965 new exception base class, BaseException, which has a new message attribute.
966 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
967 Raising a string exception now raises a DeprecationWarning.
968
Thomas Woutersfb609f42006-02-28 16:37:25 +0000969- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
970 explicitly relative, using 'from .module import name' to mean 'from the same
971 package as this module is in. Imports without dots still default to the
972 old relative-then-absolute, unless 'from __future__ import
973 absolute_import' is used.
974
Brett Cannona7446e32006-02-27 23:39:10 +0000975- Properly check if 'warnings' raises an exception (usually when a filter set
976 to "error" is triggered) when raising a warning for raising string
977 exceptions.
978
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000979- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000980 The name was removed from Include/code.h.
981
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000982- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000983
Guido van Rossum1968ad32006-02-25 22:38:04 +0000984- Patch 1433928:
985 - The copy module now "copies" function objects (as atomic objects).
986 - dict.__getitem__ now looks for a __missing__ hook before raising
987 KeyError.
988
Tim Peters84ef21c2006-02-28 20:39:06 +0000989- PEP 343: with statement implemented. Needs ``from __future__ import
990 with_statement``. Use of 'with' as a variable will generate a warning.
991 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000992 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000993 The following objects have __context__ methods:
994 - The built-in file type.
995 - The thread.LockType type.
996 - The following types defined by the threading module:
997 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
998 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000999
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001000- Fix the encodings package codec search function to only search
1001 inside its own package. Fixes problem reported in patch #1433198.
1002
1003 Note: Codec packages should implement and register their own
1004 codec search function. PEP 100 has the details.
1005
Tim Peters9ea89d22006-06-04 03:26:02 +00001006- PEP 353: Using ``Py_ssize_t`` as the index type.
1007
1008- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1009 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1010 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1011 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1012 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001013
Neal Norwitzfc76d632006-01-10 06:03:13 +00001014- Patch #1400181, fix unicode string formatting to not use the locale.
1015 This is how string objects work. u'%f' could use , instead of .
1016 for the decimal point. Now both strings and unicode always use periods.
1017
Neal Norwitz671b9e32006-01-09 07:07:12 +00001018- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1019 configure would break checking curses.h.
1020
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001021- Bug #959576: The pwd module is now builtin. This allows Python to be
1022 built on UNIX platforms without $HOME set.
1023
Neal Norwitzc10978f2005-12-19 06:07:16 +00001024- Bug #1072182, fix some potential problems if characters are signed.
1025
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001026- Bug #889500, fix line number on SyntaxWarning for global declarations.
1027
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001028- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1029
Neal Norwitze7214a12005-12-18 05:03:17 +00001030- Support for converting hex strings to floats no longer works.
1031 This was not portable. float('0x3') now raises a ValueError.
1032
Barry Warsaw2a38a862005-12-18 01:27:35 +00001033- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001034 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001035 is now displayed in interactive prompt banner.
1036
Georg Brandlfa166682005-12-17 21:45:17 +00001037- Implementation of PEP 341 - Unification of try/except and try/finally.
1038 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001039 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001040
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001041- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1042 now encodes backslash correctly.
1043
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001044- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1045
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001046- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001047 and long longs.
1048
Neal Norwitz67715f02005-11-09 06:59:35 +00001049- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001050 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001051 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001052
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001053- Replaced most Unicode charmap codecs with new ones using the
1054 new Unicode translate string feature in the builtin charmap
1055 codec; the codecs were created from the mapping tables available
1056 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1057 encodings now include a mapping for the Apple logo)
1058
Tim Peterse3547fd2005-12-16 23:13:57 +00001059- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001060
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001061- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001062
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001063- A new AST parser implementation was completed. The abstract
1064 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001065 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001066
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001067- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001068 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1069
Neal Norwitz708e51a2005-10-03 04:48:15 +00001070- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1071
Neal Norwitz11bd1192005-10-03 00:54:56 +00001072- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1073 Provide a warning when a directory is passed on the command line.
1074
Neal Norwitz40d37812005-10-02 01:48:49 +00001075- Fix segfault with invalid coding.
1076
1077- SF bug #772896: unknown encoding results in MemoryError.
1078
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001079- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001080 supported a __len__() method which evaluated to False when the iterator
1081 was empty.
1082
Guido van Rossum630db602005-09-20 18:49:54 +00001083- On 64-bit platforms, when __len__() returns a value that cannot be
1084 represented as a C int, raise OverflowError.
1085
Skip Montanarof8948ca2005-09-19 03:54:46 +00001086- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001087 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001088
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001089- SF bug #893549: parsing keyword arguments was broken with a few format
1090 codes.
1091
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001092- Changes donated by Elemental Security to make it work on AIX 5.3
1093 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1094 bug #105470: test_pwd fails on 64bit system (Opteron).
1095
Guido van Rossum539c6622005-09-14 17:49:54 +00001096- Changes donated by Elemental Security to make it work on HP-UX 11 on
1097 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1098
Georg Brandl4550b8d2005-08-26 06:43:52 +00001099- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001100 (fixes bug #1119418).
1101
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001102- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1103
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001104- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1105 exceptions that cause a function to exit.
1106
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001107- The implementation of set() and frozenset() was revised to use its
1108 own internal data structure. Memory consumption is reduced by 1/3
1109 and there are modest speed-ups as well. The API is unchanged.
1110
Tim Petersde7990b2005-07-17 23:45:23 +00001111- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1112
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001113- SF bug #1229429: PyObject_CallMethod failed to decrement some
1114 reference counts in some error exit cases.
1115
Tim Petersecc6e6a2005-07-10 22:30:55 +00001116- SF bug #1185883: Python's small-object memory allocator took over
1117 a block managed by the platform C library whenever a realloc specified
1118 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001119 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001120 portable way to copy data from the C-managed block into Python's
1121 small-object space without risking a memory fault. Python's small-object
1122 realloc now leaves such blocks under the control of the platform C
1123 realloc.
1124
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001125- SF bug #1232517: An overflow error was not detected properly when
1126 attempting to convert a large float to an int in os.utime().
1127
Raymond Hettinger3296e692005-06-29 23:29:56 +00001128- SF bug #1224347: hex longs now print with lowercase letters just
1129 like their int counterparts.
1130
Michael W. Hudson188d4362005-06-20 16:52:57 +00001131- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1132 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1133 interpreter states; back out that fix and do a better job (see
1134 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1135 for a longer write-up of the problem).
1136
Michael W. Hudsondf888462005-06-03 14:41:55 +00001137- SF patch #1180995: marshal now uses a binary format by default when
1138 serializing floats.
1139
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001140- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1141 the routines that promise to produce IEEE 754 binary representations
1142 of floats now simply copy bytes around.
1143
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001144- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1145 278.
1146
Brett Cannonc3647ac2005-04-26 03:45:26 +00001147- patch #1109424: int, long, float, complex, and unicode now check for the
1148 proper magic slot for type conversions when subclassed. Previously the
1149 magic slot was ignored during conversion. Semantics now match the way
1150 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001151 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001152 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001153 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001154
Barry Warsawc8d907c2005-04-19 23:43:40 +00001155- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1156 NULL, now raise an AttributeError when attempting to set or delete the
1157 attribute. Previously a TypeError was raised, but this was inconsistent
1158 with the equivalent pure-Python implementation.
1159
Michael W. Hudson774479c2005-04-18 08:46:17 +00001160- It is now safe to call PyGILState_Release() before
1161 PyEval_InitThreads() (note that if there is reason to believe there
1162 are multiple threads around you still must call PyEval_InitThreads()
1163 before using the Python API; this fix is for extension modules that
1164 have no way of knowing if Python is multi-threaded yet).
1165
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001166- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1167 disabled caused a crash.
1168
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001169- Bug #1165306: instancemethod_new allowed the creation of a method
1170 with im_class == im_self == NULL, which caused a crash when called.
1171
Tim Petersecc6e6a2005-07-10 22:30:55 +00001172- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001173 fixes the crash seen in bug #1165761
1174
Raymond Hettinger96229b12005-03-11 06:49:40 +00001175- Added two new builtins, any() and all().
1176
Brett Cannon409d8f22005-03-05 06:47:57 +00001177- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001178 (e.g., ``class C(): pass`` is no longer a syntax error).
1179 Patch #1176012 added support to the 'parser' module and 'compiler' package
1180 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001181
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001182- Patch #1115086: Support PY_LONGLONG in structmember.
1183
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001184- Bug #1155938: new style classes did not check that __init__() was
1185 returning None.
1186
Tim Petersecc6e6a2005-07-10 22:30:55 +00001187- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001188 ('\') with a specific error message.
1189
Martin v. Löwisff232d72005-03-03 09:24:38 +00001190- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1191
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001192- Bug #1124295: the __name__ attribute of file objects was
1193 inadvertently made inaccessible in restricted mode.
1194
Tim Petersecc6e6a2005-07-10 22:30:55 +00001195- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001196 an ferror() call.
1197
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001198- min() and max() now support key= arguments with the same meaning as in
1199 list.sort().
1200
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001201- The peephole optimizer now performs simple constant folding in expressions:
1202 (2+3) --> (5).
1203
Raymond Hettingera422c342005-01-11 03:03:27 +00001204- set and frozenset objects can now be marshalled. SF #1098985.
1205
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001206- Bug #1077106: Poor argument checking could cause memory corruption
1207 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001208
Jeremy Hyltonab630502005-02-04 18:44:06 +00001209- The parser did not complain about future statements in illegal
1210 positions. It once again reports a syntax error if a future
1211 statement occurs after anything other than a doc string.
1212
Neil Schemenauercf52c072005-08-12 17:34:58 +00001213- Change the %s format specifier for str objects so that it returns a
1214 unicode instance if the argument is not an instance of basestring and
1215 calling __str__ on the argument returns a unicode instance.
1216
Tim Petersf4e69282006-02-27 17:15:31 +00001217- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1218 current thread state when the auto-GIL-state machinery knows about
1219 it (since the thread state is being deleted, continuing to remember it
1220 can't help, but can hurt if another thread happens to get created with
1221 the same thread id).

Michael W. Hudson8137bea2005-07-27 20:24:40 +00001353- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
1354 the request code argument, which results in more C-like behaviour
1355 for large or negative values.
1356
Tim Petersecc6e6a2005-07-10 22:30:55 +00001357- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

1366 available on the platform.
1367
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001368- Bug #1166660: The readline module could segfault if hook functions
1369 were set in a different thread than that which called readline.

1372
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00001373- operator.itemgetter() and operator.attrgetter() now support retrieving

1396
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001397- the cPickle module no longer accepts the deprecated None option in the
1398 args tuple returned by __reduce__().
1399
Raymond Hettingerb2594052004-12-05 09:25:51 +00001400- itertools.islice() now accepts None for the start and step arguments.
1401 This allows islice() to work more readily with slices:
1402 islice(s.start, s.stop, s.step)
1403
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001404- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001413- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1414 been renamed to have only a single underscore prefix. This was done to
1415 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001416
Nick Coghlan43832302006-04-23 17:04:07 +00001417- PEP 338: new module runpy defines a run_module function to support
1418 executing modules which provide access to source code or a code object
1419 via the PEP 302 import mechanisms.
1420
Anthony Baxter93f5b932006-04-03 08:05:07 +00001421- The email module's parsedate_tz function now sets the daylight savings
1422 flag to -1 (unknown) since it can't tell from the date whether it should
1423 be set.
1424
Fred Drakead5177c2006-04-01 22:14:43 +00001425- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results
1426 now sport attributes that provide access to the parts of the result.
1427

1429 in attribute values.
1430
Anthony Baxterc51ee692006-04-01 00:57:31 +00001431- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001432 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001433 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001434 module will not be built.
1435
Tim Petersc17976e2006-04-01 00:26:53 +00001436- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1437 aren't officially supported here, and trying to use them will probably
1438 raise an exception some day. But dicts have been allowed, and "mostly
1439 worked", so support for them won't go away without warning.
1440
Georg Brandl338ef7d2006-03-31 18:42:16 +00001441- Bug #1445068: getpass.getpass() can now be given an explicit stream
1442 argument to specify where to write the prompt.
1443
Georg Brandl22ec80b2006-03-31 18:25:44 +00001444- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1459
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001460- email 4.0 package now integrated. This is largely the same as the email 3.0
1461 package that was included in Python 2.3, except that PEP 8 module names are
1462 now used (e.g. mail.message instead of email.Message). The MIME classes
1463 have been moved to a subpackage (e.g. email.mime.text instead of
1464 email.MIMEText). The old names are still supported for now. Several
1465 deprecated Message methods have been removed and lots of bugs have been
1466 fixed. More details can be found in the email package documentation.
1467
Walter Dörwald40108c92006-03-27 08:15:44 +00001468- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1469 (a subclass of tuple) that provides incremental decoders and encoders
1470 (a way to use stateful codecs without the stream API). Python functions
1471 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1472 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1473 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001475- Patch #1359365: Calling next() on a closed StringIO.String object raises
1476 a ValueError instead of a StopIteration now (like file and cString.String do).
1477 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1478 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001479

1558 expressed at the NIST Hash Function Workshop 10/31/05),
1559 is that SHA-256 is a good choice for the time being, but
1560 that research should continue, and other alternatives may
1561 arise from this research. The larger SHA's also seem OK."

Martin v. Löwis22b457e2005-01-16 08:40:58 +00001739- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1740
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001741- Enhancements to the csv module:
1742
1743 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001744 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001745 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001746 + Dialect parameter parsing has been re-implemented to improve error
1747 reporting.
1748 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1749 dictates.
1750 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001751 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001752 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001753 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1754 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001755 + reader now allows \r characters to be quoted (previously it only allowed
1756 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001757 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001758 + Dialect classes passed to the module are no longer instantiated by
1759 the module before being parsed (the former validation scheme required
1760 this, but the mechanism was unreliable).
1761 + The dialect registry now contains instances of the internal
1762 C-coded dialect type, rather than references to python objects.
1763 + the internal c-coded dialect type is now immutable.
1764 + register_dialect now accepts the same keyword dialect specifications
1765 as the reader and writer, allowing the user to register dialects
1766 without first creating a dialect class.
1767 + a configurable limit to the size of parsed fields has been added -
1768 previously, an unmatched quote character could result in the entire
1769 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001770 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001771 the parser field size limit (returning the former limit). The initial
1772 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001773 + A line_num attribute has been added to the reader object, which tracks
1774 the number of lines read from the source iterator. This is not
1775 the same as the number of records returned, as records can span
1776 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001777 + reader and writer objects were not being registered with the cyclic-GC.
1778 This has been fixed.
1779
Brett Cannone6539c42005-01-08 02:43:53 +00001780- _DummyThread objects in the threading module now delete self.__block that is
1781 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1782 lock primitives tend to be limited in number and thus should not be wasted on
1783 a _DummyThread object. Fixes bug #1089632.
1784
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001785- The imghdr module now detects Exif files.
1786
Raymond Hettinger6065d322004-12-20 23:51:53 +00001787- StringIO.truncate() now correctly adjusts the size attribute.
1788 (Bug #951915).
1789
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001790- locale.py now uses an updated locale alias table (built using
1791 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1792 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001793 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001794
Raymond Hettinger3557f422004-12-07 12:02:02 +00001795- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1796
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001797- the pickle module no longer accepts the deprecated None option in the
1798 args tuple returned by __reduce__().
1799
Brett Cannon84667c02004-12-07 03:25:18 +00001800- optparse now optionally imports gettext. This allows its use in setup.py.
1801
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001802- the pickle module no longer uses the deprecated bin parameter.
1803
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001804- the shelve module no longer uses the deprecated binary parameter.
1805
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001806- the pstats module no longer uses the deprecated ignore() method.
1807
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001808- the filecmp module no longer uses the deprecated use_statcache argument.
1809
Raymond Hettinger664347b2004-12-04 21:21:53 +00001810- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1811 extended or overridden by subclasses. Formerly, the subclassed method would
1812 be ignored by the rest of the module. (Bug #1078905).
1813
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001814- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001815 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001816
Walter Dörwald36733692004-12-22 12:50:50 +00001817- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1818 once when a size argument is given. This prevents a buffer overflow in the
1819 tokenizer with very long source lines.
1820
Barry Warsaw538561e2006-01-01 21:48:54 +00001821- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1822 immediately after creating the object, without any intervening
1823 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001824
Skip Montanaro05885812005-01-16 20:48:27 +00001825- The reconvert.quote function can now emit triple-quoted strings. The
1826 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001827
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001828- ``UserString.MutableString`` now supports negative indices in
1829 ``__setitem__`` and ``__delitem__``
1830
Greg Ward40407942005-03-05 02:53:17 +00001831- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1832 correctly.
1833
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001834- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1835 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1836 character even if the user has passed a size parameter to get a proper
1837 line ending. Remove the special handling of a "\r\n" that has been split
1838 between two lines.
1839
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001840- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1841 about illegal code points. The codec now supports PEP 293 style error
1842 handlers.
1843
Walter Dörwald78a78b02005-09-01 12:04:29 +00001844- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001845 from the input stream, so that the output is a byte string in the correct
1846 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001847
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001848- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1849 considering it exactly like a '*'.
1850
Walter Dörwald007f8df2005-10-09 19:42:27 +00001851- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1852 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001853
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001854- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1855
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001856- Patch #1413711: Certain patterns of differences were making difflib
1857 touch the recursion limit.
1858
Walter Dörwald58917a62006-03-31 15:26:22 +00001859- Bug #947906: An object oriented interface has been added to the calendar
1860 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001861 called as a script (e.g. via ``python -mcalendar``). Localized month and
1862 weekday names can be ouput (even if an exotic encoding is used) using
1863 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001864
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001865Build
1866-----
1867
Neal Norwitz602d3392006-03-31 08:21:40 +00001868- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1869 by using -mieee gcc option.
1870

1872
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001873- Build support for Win64-AMD64 was added.
1874
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001875- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1876
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001877- Patch #881820: look for openpty and forkpty also in libbsd.
1878
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001879- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1880 The zlib module is now builtin on Windows.
1881
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001882- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1883
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001884- Bug #1189330: configure did not correctly determine the necessary
1885 value of LINKCC if python was built with GCC 4.0.
1886
Trent Mick8321b422005-07-26 02:29:21 +00001887- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1888 vulnerability in zlib 1.2.1 and 1.2.2.
1889
Brett Cannon08cd5982005-04-24 22:26:38 +00001890- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1891 flags that change binary compatibility. Changes were also made to
1892 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001893 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001894
Bob Ippolitoed233462005-03-29 13:47:59 +00001895- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1896 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1897 no longer exists). This configure patch makes things right.
1898
Martin v. Löwise2713be2005-03-08 15:03:08 +00001899- Bug #1158607: Build with --disable-unicode again.
1900
Brett Cannon46d96232005-02-16 00:07:19 +00001901- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1902 defined. Discovered as a result of not being able to build on OS X.
1903
Brett Cannon516592f2004-12-07 00:42:59 +00001904- setup.py now uses the directories specified in LDFLAGS using the -L option
1905 and in CPPFLAGS using the -I option for adding library and include
1906 directories, respectively, for compiling extension modules against. This has
1907 led to the core being compiled using the values in CPPFLAGS. It also removes
1908 the need for the special-casing of both DarwinPorts and Fink for darwin since
1909 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1910 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1911 Fink, ``-I/opt/local/include`` for DarwinPorts).
1912
Brett Cannon43802422005-02-10 20:48:03 +00001913- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1914 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1915 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1916 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001918C API
1919-----
1920
Tim Petersc9d78aa2006-03-26 23:27:58 +00001921- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1922 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1923 is obtained via the ``PyObject_`` family, it must be released via the
1924 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1925 always been officially true, but when Python's small-object allocator was
1926 introduced, an attempt was made to cater to a few extension modules
1927 discovered at the time that obtained memory via ``PyObject_New`` but
1928 released it via ``PyMem_DEL``. It's years later, and if such code still
1929 exists it will fail now (probably with segfaults, but calling wrong
1930 low-level memory management functions can yield many symptoms).
1931
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001932- Added a C API for set and frozenset objects.
1933
Raymond Hettinger66517482004-12-03 11:45:13 +00001934- Removed PyRange_New().
1935
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001936- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1937 mapping argument now. This string is used as a mapping table. Byte values
1938 greater than the length of the string and 0xFFFE are treated as undefined
1939 mappings.
