89Core and builtins
90-----------------
91
Marc-André Lemburg040f76b2006-08-14 10:55:19 +000092- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +000093 compared equal or unequal to a string and a UnicodeDecodeError
94 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +000095
Marc-André Lemburg040f76b2006-08-14 10:55:19 +000096 Instead, the equal (==) and unequal (!=) comparison operators will
97 now issue a UnicodeWarning and interpret the two objects as
98 unequal. The UnicodeWarning can be filtered as desired using
99 the warning framework, e.g. silenced completely, turned into an
100 exception, logged, etc.
101
102 Note that compare operators other than equal and unequal will still
103 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000104
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000105- Fix segfault when doing string formatting on subclasses of long.
106
107- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
108 with new-style classes.
109
110- Fix bug related to __len__ functions returning negative values with
111 classic classes.
112
113- Patch #1538606, Fix __index__() clipping. There were some problems
114 discovered with the API and how integers that didn't fit into Py_ssize_t
115 were handled. This patch attempts to provide enough alternatives
116 to effectively use __index__.
117
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000118- Bug #1536021: __hash__ may now return long int; the final hash
119 value is obtained by invoking hash on the long int.
120
Thomas Hellerab1049c2006-08-08 17:37:00 +0000121- Bug #1536786: buffer comparison could emit a RuntimeWarning.
122
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000123- Bug #1535165: fixed a segfault in input() and raw_input() when
124 sys.stdin is closed.
125
Thomas Heller74d36f02006-08-04 18:17:40 +0000126- On Windows, the PyErr_Warn function is now exported from
127 the Python dll again.
128
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000129- Bug #1191458: tracing over for loops now produces a line event
130 on each iteration. Fixing this problem required changing the .pyc
131 magic number. This means that .pyc files generated before 2.5c1
132 will be regenerated.
133
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000134- Bug #1333982: string/number constants were inappropriately stored
135 in the byte code and co_consts even if they were not used, ie
136 immediately popped off the stack.
137
Georg Brandle9462c72006-08-04 18:03:37 +0000138- Fixed a reference-counting problem in property().

141Library
142-------
143
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000144- Fix a bug in the ``compiler`` package that caused invalid code to be
145 generated for generator expressions.
146
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000147- The distutils version has been changed to 2.5.0. The change to
148 keep it programmatically in sync with the Python version running
149 the code (introduced in 2.5b3) has been reverted. It will continue
150 to be maintained manually as static string literal.
151
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000152- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000153 and this cannot be converted to the required C type, an exception is
154 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000155 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000156
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000157- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000158 an exception.
159
Tim Peterscbdd3502006-09-05 01:47:53 +0000160- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000161 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000162 workarounds for clocks with low resolution, to stop the code yielding
163 duplicate UUIDs.
164
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000165- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
166 before raising SystemExit, allowing IDLE to honor quit() and exit().
167
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000168- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
169
Georg Brandl7a1af772006-08-14 21:55:28 +0000170- Patch #1536071: trace.py should now find the full module name of a
171 file correctly even on Windows.
172
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000173- logging's atexit hook now runs even if the rest of the module has
174 already been cleaned up.
175
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000176- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000177
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000178- Bug #1531405, format_exception no longer raises an exception if
179 str(exception) raised an exception.
180
Neil Schemenauer06ded092006-08-04 16:20:30 +0000181- Fix a bug in the ``compiler`` package that caused invalid code to be
182 generated for nested functions.

189
Georg Brandl3335a7a2006-08-14 21:42:55 +0000190- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
191 raises the correct exceptions.
192
Thomas Heller1ce433e2006-08-14 16:20:04 +0000193- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
194 '-no-stack-protector' compiler flag for OpenBSD has been removed.
195
Thomas Heller86720042006-08-14 11:17:48 +0000196- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
197 uses the _as_parameter_ attribute when objects are passed to foreign
198 function calls. The ctypes version number was changed to 1.0.1.
199
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000200- Bug #1530559, struct.pack raises TypeError where it used to convert.
201 Passing float arguments to struct.pack when integers are expected
202 now triggers a DeprecationWarning.

Andrew MacIntyre16ee33a2006-08-06 12:37:03 +0000215- test_threading now skips testing alternate thread stack sizes on
216 platforms that don't support changing thread stack size.
217
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000218

252Core and builtins
253-----------------
254
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000255- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000256 returned a long (see PEP 353).
257
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000258- Bug #1515471: string.replace() accepts character buffers again.
259
Neal Norwitz07aadb12006-07-30 06:55:48 +0000260- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
261 This provides the proper warning for struct.pack().
262 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
263
Neal Norwitz0d62a062006-07-30 06:53:31 +0000264- Patch #1531113: Fix augmented assignment with yield expressions.
265 Also fix a SystemError when trying to assign to yield expressions.
266
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000267- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
268 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
269 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
270 excessive filesystem operations during imports.
271
Tim Petersbc24eee2006-07-27 01:14:53 +0000272- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
273 operations on signed longs that are formally undefined by C.
274 Unfortunately, at least one compiler now cares about that, so complicated
275 the code to make that compiler happy again.
276
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000277- Bug #1524310: Properly report errors from FindNextFile in os.listdir.

283
Neal Norwitze7563102006-07-17 01:00:16 +0000284- Fix warnings reported by Klocwork's static analysis tool.
285
Neal Norwitz84be93b2006-07-16 01:50:38 +0000286- Bug #1512814, Fix incorrect lineno's when code within a function
287 had more than 255 blank lines.
288
Georg Brandl9dceedb2006-07-12 15:31:17 +0000289- Patch #1521179: Python now accepts the standard options ``--help`` and
290 ``--version`` as well as ``/?`` on Windows.
291
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000292- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000293 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000294 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000295
Tim Peters112aad32006-07-19 00:03:19 +0000296- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000297 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000298 new ``sys._current_frames()`` returns a dictionary with one entry,
299 mapping the faux "thread id" 0 to the current frame.
300
Ronald Oussoren3075e162006-07-25 20:28:55 +0000301- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

Martin v. Löwis961b91b2006-08-02 13:53:55 +0000307- Correction of patch #1455898: In the mbcs decoder, set final=False
308 for stream decoder, but final=True for the decode function.
309
Georg Brandl07fec3a2006-08-01 18:49:24 +0000310- os.urandom no longer masks unrelated exceptions like SystemExit or
311 KeyboardInterrupt.
312
Tim Peters4643c2f2006-08-10 22:45:34 +0000313- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000314 shutil.copytree on Windows
315
Georg Brandle34ac7c2006-07-30 11:07:23 +0000316- Bug #1002398: The documentation for os.path.sameopenfile now correctly
317 refers to file descriptors, not file objects.
318
Tim Peterscbdd3502006-09-05 01:47:53 +0000319- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000320 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000321 #1513611, and probably others.
322
Georg Brandledd9b0d2006-07-29 09:33:26 +0000323- Bug #1441397: The compiler module now recognizes module and function
324 docstrings correctly as it did in Python 2.4.
325
Tim Peters6f681472006-07-27 23:44:37 +0000326- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
327 lost that tests are sorted by name before being run. This rarely
328 matters for well-written tests, but can create baffling symptoms if
329 side effects from one test to the next affect outcomes. ``DocTestFinder``
330 has been changed to sort the list of tests it returns.
331
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000332- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000333 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000334
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000335- Bug #978833: Really close underlying socket in _socketobject.close.
336
Georg Brandldb232dc2006-08-20 13:15:43 +0000337- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
338 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000339
Georg Brandlcf0c1722006-07-26 07:23:32 +0000340- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
341 to recursive calls and call it with the failing package name.
342
Martin v. Löwis0b483032006-07-25 09:53:12 +0000343- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
344
Georg Brandlc13c34c2006-07-24 14:09:56 +0000345- Patch #1515343: Fix printing of deprecated string exceptions with a
346 value in the traceback module.
347
Greg Ward48fae7a2006-07-23 16:05:51 +0000348- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
349
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000350- Patch #1524429: Use repr() instead of backticks in Tkinter again.
351
Brett Cannoncaebe222006-07-18 04:41:36 +0000352- Bug #1520914: Change time.strftime() to accept a zero for any position in its
353 argument tuple. For arguments where zero is illegal, the value is forced to
354 the minimum value that is correct. This is to support an undocumented but
355 common way people used to fill in inconsequential information in the time
356 tuple pre-2.4.
357
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000358- Patch #1220874: Update the binhex module for Mach-O.
359
Barry Warsawb110bad2006-07-21 14:51:07 +0000360- The email package has improved RFC 2231 support, specifically for
361 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
362 (name*0=<blah>) parameter continuations. This may change the types of
363 values returned from email.message.Message.get_param() and friends.
364 Specifically in some cases where non-encoded continuations were used,
365 get_param() used to return a 3-tuple of (None, None, string) whereas now it
366 will just return the string (since non-encoded continuations don't have
367 charset and language parts).
368
369 Also, whereas % values were decoded in all parameter continuations, they are
370 now only decoded in encoded parameter parts.
371
Ronald Oussoren3075e162006-07-25 20:28:55 +0000372- Bug #1517990: IDLE keybindings on MacOS X now work correctly
373
374- Bug #1517996: IDLE now longer shows the default Tk menu when a
375 path browser, class browser or debugger is the frontmost window on MacOS X
376
Barry Warsaw00decd72006-07-27 23:43:15 +0000377- Patch #1520294: Support for getset and member descriptors in types.py,
378 inspect.py, and pydoc.py. Specifically, this allows for querying the type
379 of an object against these built-in types and more importantly, for getting
380 their docstrings printed in the interactive interpreter's help() function.

384-----------------
385
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000386- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
387 a socket operation on a socket with a timeout, the exception will be
388 caught correctly. Previously, the exception was not caught.
389
Thomas Heller1393d6a2006-07-28 21:43:20 +0000390- Patch #1529514: The _ctypes extension is now compiled on more
391 openbsd target platforms.
392
Tim Peters9cab5932006-07-28 00:30:00 +0000393- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
394 a memory leak, affecting pickles and deep copies.
395
Tim Petersbc24eee2006-07-27 01:14:53 +0000396- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

398
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000399- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
400
Thomas Hellerce049a02006-07-14 17:51:14 +0000401- Patch #1521817: Index range checking on ctypes arrays containing
402 exactly one element enabled again. This allows iterating over these
403 arrays, without the need to check the array size before.
404
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000405- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000406 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000407 /dev/null in certain cases; this is now fixed.
408
Thomas Heller47d7a062006-07-12 08:43:47 +0000409- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
410 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000411
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000412- Because of a misspelled preprocessor symbol, ctypes was always
413 compiled without thread support; this is now fixed.
414
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000415- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
416 methods now allow their database parameter to be None as the
417 sleepycat API allows.
418
Matt Flemingec926502006-07-28 11:27:27 +0000419- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
420 bluetooth API compared with Linux and FreeBSD.
421
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000422Tests
423-----
424
425- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
426 how long the test file should take to play. Now accepts taking 2.93 secs
427 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
428
Georg Brandl4793aa32006-07-28 18:31:39 +0000429- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
430 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
431 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000432

436- Bug #1439538: Drop usage of test -e in configure as it is not portable.
437
Ronald Oussoren26cad082006-08-01 21:00:57 +0000438Mac
439---
440
441- PythonLauncher now works correctly when the path to the script contains
442 characters that are treated specially by the shell (such as quotes).
443
444- Bug #1527397: PythonLauncher now launches scripts with the working directory
445 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000446 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000447 expect.

455Core and builtins
456-----------------
457
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000458- Bug #1441486: The literal representation of -(sys.maxint - 1)
459 again evaluates to a int object, not a long.
460
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000461- Bug #1501934: The scope of global variables that are locally assigned
462 using augmented assignment is now correctly determined.
463
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000464- Bug #927248: Recursive method-wrapper objects can now safely
465 be released.
466
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000467- Bug #1417699: Reject locale-specific decimal point in float()
468 and atof().
469
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000470- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
471 omit a default "error" argument for NULL pointer. This allows
472 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000473
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000474- Bug #1519018: 'as' is now validated properly in import statements.
475
Neal Norwitz28746ab2006-07-09 22:14:42 +0000476- On 64 bit systems, int literals that use less than 64 bits are
477 now ints rather than longs.
478
Neal Norwitzed657552006-07-10 00:04:44 +0000479- Bug #1512814, Fix incorrect lineno's when code at module scope
480 started after line 256.
481
Tim Peters32a83612006-07-10 21:08:24 +0000482- New function ``sys._current_frames()`` returns a dict mapping thread
483 id to topmost thread stack frame. This is for expert use, and is
484 especially useful for debugging application deadlocks. The functionality
485 was previously available in Fazal Majid's ``threadframe`` extension
486 module, but it wasn't possible to do this in a wholly threadsafe way from
487 an extension.

Tim Peters32a83612006-07-10 21:08:24 +0000497- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000498 environment variable to be set in order to the SDK environment
499 for finding the compiler, include files, etc.

504
Thomas Woutersadd19112006-07-05 11:03:49 +0000505- string.Template() now correctly handles tuple-values. Previously,
506 multi-value tuples would raise an exception and single-value tuples would
507 be treated as the value they contain, instead.
508
Martin v. Löwisede77f52006-07-03 13:01:35 +0000509- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

Martin v. Löwis2b88f632006-07-03 10:19:49 +0000519 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000520

522 is created.
523

528 attribute values.
529
530- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
531 sgmllib ('[' and ']' were not accepted).
532
Georg Brandl1be63af2006-06-28 20:23:25 +0000533- Fix a bug in the turtle module's end_fill function.
534
Brett Cannon53ab5b72006-06-22 16:49:14 +0000535- Bug #1510580: The 'warnings' module improperly required that a Warning
536 category be either a types.ClassType and a subclass of Warning. The proper
537 check is just that it is a subclass with Warning as the documentation states.
538
Georg Brandlad29e632006-06-21 17:45:17 +0000539- The compiler module now correctly compiles the new try-except-finally
540 statement (bug #1509132).
541
Neal Norwitz60373cd2006-06-22 06:30:50 +0000542- The wsgiref package is now installed properly on Unix.
543
Vinay Sajip28e57612006-07-01 10:45:20 +0000544- A bug was fixed in logging.config.fileConfig() which caused a crash on
545 shutdown when fileConfig() was called multiple times.
546
Gerhard Häring762fbd32006-07-02 17:48:30 +0000547- The sqlite3 module did cut off data from the SQLite database at the first
548 null character before sending it to a custom converter. This has been fixed
549 now.

552-----------------
553
Tim Peters112aad32006-07-19 00:03:19 +0000554- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
555 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
556 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000557
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000558- Assigning None to pointer type fields in ctypes structures possible
559 overwrote the wrong fields, this is fixed now.
560
561- Fixed a segfault in _ctypes when ctypes.wintypes were imported
562 on non-Windows platforms.
563
564- Bug #1518190: The ctypes.c_void_p constructor now accepts any
565 integer or long, without range checking.
566
567- Patch #1517790: It is now possible to use custom objects in the ctypes
568 foreign function argtypes sequence as long as they provide a from_param
569 method, no longer is it required that the object is a ctypes type.
570
571- The '_ctypes' extension module now works when Python is configured
572 with the --without-threads option.
573
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000574- Bug #1513646: os.access on Windows now correctly determines write
575 access, again.
576
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000577- Bug #1512695: cPickle.loads could crash if it was interrupted with

589
Tim Peters32a83612006-07-10 21:08:24 +0000590- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000591 Previously, the slight difference could cause compilation errors of the
592 'zlib' module on systems with more than one version of zlib.
593
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000594- The MSI compileall step was fixed to also support a TARGETDIR

613 documentation for the warnings module.
614
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000615- Patch #1509163: MS Toolkit Compiler no longer available.
616

Anthony Baxterd1136802006-06-19 12:04:15 +0000623*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000624
625Core and builtins
626-----------------
627
Georg Brandla56b9152006-06-19 06:35:54 +0000628- Patch #1507676: Error messages returned by invalid abstract object operations
629 (such as iterating over an integer) have been improved and now include the
630 type of the offending object to help with debugging.
631
Brett Cannonea3912b2006-06-13 21:46:41 +0000632- Bug #992017: A classic class that defined a __coerce__() method that returned
633 its arguments swapped would infinitely recurse and segfault the interpreter.
634
Neal Norwitz909eb122006-06-12 02:13:21 +0000635- Fix the socket tests so they can be run concurrently.
636
Neal Norwitzb9845e72006-06-12 02:11:18 +0000637- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000638 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000639
Brett Cannon22565aa2006-06-09 22:31:23 +0000640- Bug #532646: object.__call__() will continue looking for the __call__
641 attribute on objects until one without one is found. This leads to recursion
642 when you take a class and set its __call__ attribute to an instance of the
643 class. Originally fixed for classic classes, but this fix is for new-style.
644 Removes the infinite_rec_3 crasher.
645
Georg Brandl24250812006-06-09 18:45:48 +0000646- The string and unicode methods startswith() and endswith() now accept
647 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
648
Brett Cannonde3b0522006-06-08 17:00:45 +0000649- Buffer objects, at the C level, never used the char buffer
650 implementation even when the char buffer for the wrapped object was
651 explicitly requested (originally returned the read or write buffer).
652 Now a TypeError is raised if the char buffer is not present but is
653 requested.
654
Georg Brandlddbaa662006-06-04 21:56:52 +0000655- Patch #1346214: Statements like "if 0: suite" are now again optimized
656 away like they were in Python 2.4.
657
Georg Brandlb7c8f542006-05-27 12:30:25 +0000658- Builtin exceptions are now full-blown new-style classes instead of
659 instances pretending to be classes, which speeds up exception handling
660 by about 80% in comparison to 2.5a2.
661
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000662- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
663 Unicode 4.1.
664
Georg Brandlf4ef1162006-05-26 18:03:31 +0000665- Patch #921466: sys.path_importer_cache is now used to cache valid and
666 invalid file paths for the built-in import machinery which leads to
667 fewer open calls on startup.
668
Tim Peters696cf432006-05-24 21:10:40 +0000669- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
670 of-2 bases. The largest speedup is for inputs with about 1000 decimal
671 digits. Conversion from non-power-of-2 bases remains quadratic-time in
672 the number of input digits (it was and remains linear-time for bases
673 2, 4, 8, 16 and 32).
674
Tim Petersb713ec22006-05-23 18:45:30 +0000675- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
676 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
677 an integer close to ``sys.maxint``. This was repaired by patch
678 #1335972, which also gives a nice speedup.
679
Richard Jonescebbefc2006-05-23 18:28:17 +0000680- Patch #1337051: reduced size of frame objects.
681
682- PyErr_NewException now accepts a tuple of base classes as its
683 "base" parameter.
684
Richard Jones7c88dcc2006-05-23 10:37:38 +0000685- Patch #876206: function call speedup by retaining allocated frame
686 objects.
687
Georg Brandl7b90e162006-05-18 07:01:27 +0000688- Bug #1462152: file() now checks more thoroughly for invalid mode
689 strings and removes a possible "U" before passing the mode to the
690 C library function.
691
Neal Norwitz1004a532006-05-15 07:17:23 +0000692- Patch #1488312, Fix memory alignment problem on SPARC in unicode
693
Neal Norwitz373f0a72006-05-15 07:04:36 +0000694- Bug #1487966: Fix SystemError with conditional expression in assignment
695
Martin v. Löwis879768d2006-05-11 13:28:43 +0000696- WindowsError now has two error code attributes: errno, which carries
697 the error values from errno.h, and winerror, which carries the error
698 values from winerror.h. Previous versions put the winerror.h values
699 (from GetLastError()) into the errno attribute.
700
Martin v. Löwis77736712006-05-04 05:51:03 +0000701- Patch #1475845: Raise IndentationError for unexpected indent.
702
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000703- Patch #1479181: split open() and file() from being aliases for each other.
704
Tim Peters44bd9862006-06-01 13:49:23 +0000705- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
706 methods were always silently ignored by dictionaries when comparing keys.
707 They are now passed through (except when using the C API function
708 ``PyDict_GetItem()``, whose semantics did not change).
709
710- Bug #1456209: In some obscure cases it was possible for a class with a
711 custom ``__eq__()`` method to confuse dict internals when class instances
712 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
713 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000715Extension Modules
716-----------------
717
Trent Mick960a3f82006-06-28 20:30:41 +0000718- Bug #1295808: expat symbols should be namespaced in pyexpat
719
720- Patch #1462338: Upgrade pyexpat to expat 2.0.0
721
Brett Cannon6ee7d012006-06-08 16:23:04 +0000722- Change binascii.hexlify to accept a read-only buffer instead of only a char
723 buffer and actually follow its documentation.
724
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000725- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
726
Nick Coghlanc649ec52006-05-29 12:43:05 +0000727- Patch #1478788 (modified version): The functional extension module has
728 been renamed to _functools and a functools Python wrapper module added.
729 This provides a home for additional function related utilities that are
730 not specifically about functional programming. See PEP 309.
731
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000732- Patch #1493701: performance enhancements for struct module.
733
Georg Brandl378d5922006-05-17 14:26:50 +0000734- Patch #1490224: time.altzone is now set correctly on Cygwin.
735
Georg Brandl8d3342b2006-05-16 07:38:27 +0000736- Patch #1435422: zlib's compress and decompress objects now have a
737 copy() method.
738
Andrew MacIntyre92913322006-06-13 15:04:24 +0000739- Patch #1454481: thread stack size is now tunable at runtime for thread
740 enabled builds on Windows and systems with Posix threads support.
741
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000742- On Win32, os.listdir now supports arbitrarily-long Unicode path names
743 (up to the system limit of 32K characters).
744
745- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
746 As a result, these functions now raise WindowsError instead of OSError.
747
Tim Peters7a822da2006-05-25 21:50:17 +0000748- ``time.clock()`` on Win64 should use the high-performance Windows
749 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
750 Windows platforms).
751
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000752- Calling Tk_Init twice is refused if the first call failed as that
753 may deadlock.
754
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000755- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
756 accept it without potentially using an uninitialized pointer.
757
758- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
759 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
760 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000761
Gregory P. Smith372b5832006-06-05 18:48:21 +0000762- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000763 [pybsddb project SF patch number 1466734]
764
Gregory P. Smith372b5832006-06-05 18:48:21 +0000765- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
766 parameter is supplied. [SF pybsddb bug #1477863]
767
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000768- bsddb: the __len__ method of a DB object has been fixed to return correct
769 results. It could previously incorrectly return 0 in some cases.
770 Fixes SF bug 1493322 (pybsddb bug 1184012).
771
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000772- bsddb: the bsddb.dbtables Modify method now raises the proper error and
773 aborts the db transaction safely when a modifier callback fails.
774 Fixes SF python patch/bug #1408584.
775
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000776- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000777 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000778 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
779 database calls that would previously deadlock. [SF python bug #775414]
780
Vinay Sajip28e57612006-07-01 10:45:20 +0000781- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000782
Walter Dörwald4994d952006-06-19 08:07:50 +0000783- Patch #1506645: add Python wrappers for the curses functions
784 is_term_resized, resize_term and resizeterm.

787-------
788
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000789- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
790 functions.
791
Martin v. Löwis3798da02006-06-17 18:44:27 +0000792- Patch #812986: Update turtle output even if not tracing.
793
Vinay Sajip28e57612006-07-01 10:45:20 +0000794- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000795 Tkinter.BaseWidget.
796
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000797- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
798
Martin v. Löwis337487e2006-06-17 09:15:14 +0000799- Patch #763580: Add name and value arguments to Tkinter variable
800 classes.
801
Georg Brandl83cc0d02006-06-14 08:50:03 +0000802- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
803 mime.types file for determining MIME types.
804
Georg Brandl2605ca82006-06-14 06:08:31 +0000805- Bug #1339007: Shelf objects now don't raise an exception in their
806 __del__ method when initialization failed.
807
Martin v. Löwisd8251432006-06-14 05:21:04 +0000808- Patch #1455898: The MBCS codec now supports the incremental mode for
809 double-byte encodings.
810
Tim Peters43898b42006-06-14 04:09:25 +0000811- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
812 guarantee that adjacent triples in the return list always describe
813 non-adjacent blocks. Previously, a pair of matching blocks could end
814 up being described by multiple adjacent triples that formed a partition
815 of the matching pair.
816
Greg Ward0e0c9f42006-06-11 16:24:11 +0000817- Bug #1498146: fix optparse to handle Unicode strings in option help,
818 description, and epilog.
819
Greg Wardd1c797e2006-06-11 14:42:41 +0000820- Bug #1366250: minor optparse documentation error.
821
Greg Ward7f547402006-06-11 00:40:49 +0000822- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
823 clarify docs.
824
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000825- The wsgiref package has been added to the standard library.
826
Nick Coghlan676725d2006-06-08 13:54:49 +0000827- The functions update_wrapper() and wraps() have been added to the functools
828 module. These make it easier to copy relevant metadata from the original
829 function when writing wrapper functions.
830
Tim Petersd6a9eef2006-06-05 01:48:21 +0000831- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
832 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000833
Martin v. Löwis3f767792006-06-04 19:36:28 +0000834- Patch #1359618: Speed up charmap encoder by using a trie structure
835 for lookup.
836
Tim Petersd609b1a2006-06-02 23:22:51 +0000837- The functions in the ``pprint`` module now sort dictionaries by key
838 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
839 if and only if its display required more than one line, although that
840 wasn't documented. The new behavior increases predictability; e.g.,
841 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
842
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000843- Patch #1497027: try HTTP digest auth before basic auth in urllib2
844 (thanks for J. J. Lee).
845
Georg Brandl2b330372006-05-28 20:23:12 +0000846- Patch #1496206: improve urllib2 handling of passwords with respect to
847 default HTTP and HTTPS ports.
848
George Yoshidaf3c65de2006-05-28 16:39:09 +0000849- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
850
Bob Ippolito7298f272006-05-23 18:43:47 +0000851- Patch #1281707: speed up gzip.readline.
852
Georg Brandlb89316f2006-05-17 15:51:16 +0000853- Patch #1180296: Two new functions were added to the locale module:
854 format_string() to get the effect of "format % items" but locale-aware,
855 and currency() to format a monetary number with currency sign.
856
Georg Brandle3a25832006-05-17 14:56:04 +0000857- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
858 and several features added, such as speed and geometry control.
859
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000860- Patch #1488881: add support for external file objects in bz2 compressed
861 tarfiles.
862
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000863- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
864 stdout arguments, making it possible to redirect input and output
865 for remote debugging.
866
867- Patch #1484695: Update the tarfile module to version 0.8. This fixes
868 a couple of issues, notably handling of long file names using the
869 GNU LONGNAME extension.
870
871- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
872 new flag when ``name`` is already the name of an option flag.
873
874- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
875 package.
876
877- Patch #1472854: make the rlcompleter.Completer class usable on non-
878 UNIX platforms.
879
880- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
881
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000882- Bug #1472827: correctly escape newlines and tabs in attribute values in
883 the saxutils.XMLGenerator class.

918Core and builtins
919-----------------
920
Thomas Heller1b046642006-04-18 18:51:06 +0000921- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
922 by converting these apis from macros into exported functions again:
923
924 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile

Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000932- All uses of PyStructSequence_InitType have been changed to initialize
933 the type objects only once, even if the interpreter is initialized
934 multiple times.
935
Neal Norwitz61546162006-04-14 05:20:28 +0000936- Bug #1454485, array.array('u') could crash the interpreter. This was
937 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
938 to unicode when it didn't make sense. 'u#' now requires a unicode string.
939
940- Py_UNICODE is unsigned. It was always documented as unsigned, but
941 due to a bug had a signed value in previous versions.
942
Tim Peters3a5e8b12006-04-11 01:44:07 +0000943- Patch #837242: ``id()`` of any Python object always gives a positive
944 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
945 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000946 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000947 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000948
Tim Peters3a5e8b12006-04-11 01:44:07 +0000949 def __hash__(self):
950 return id(self) # WRONG
951
952 because a hash result must be a (short) Python int but it was always
953 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000954 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000955 was always usable as a hash value before this patch. That's no longer
956 necessarily so.
957
958- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000959 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000960 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000961 #1454844)
962
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000963- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
964 involving generators that have paused outside of any ``try`` or ``with``
965 blocks. (In 2.5a1, a paused generator that was part of a reference
966 cycle could not be garbage collected, regardless of whether it was
967 paused in a ``try`` or ``with`` block.)

973 is a macro.
974
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000975- Bug #1467952: os.listdir() now correctly raises an error if readdir()
976 fails with an error condition.
977
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000978- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
979
980- Bug #1117761: bsddb.*open() no longer raises an exception when using
981 the cachesize parameter.
982
983- Bug #1149413: bsddb.*open() no longer raises an exception when using
984 a temporary db (file=None) with the 'n' flag to truncate on open.
985
986- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
987 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000988
Armin Rigoa9017c32006-04-19 11:50:27 +0000989- Patch #1062014: AF_UNIX sockets under Linux have a special
990 abstract namespace that is now fully supported.
991
Anthony Baxter51bcb682006-04-05 14:51:42 +0000992Library
993-------
994
Peter Astrand7d1d4362006-07-14 14:04:45 +0000995- Bug #1223937: subprocess.CalledProcessError reports the exit status
996 of the process using the returncode attribute, instead of
997 abusing errno.
998
Tim Peters711bf302006-04-25 03:31:36 +0000999- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1000 a doctest to be skipped (the code is not run, and the expected output
1001 or exception is ignored).
1002
Nick Coghlanda2268f2006-04-24 04:37:15 +00001003- Fixed contextlib.nested to cope with exceptions being raised and
1004 caught inside exit handlers.
1005
Greg Wardab05edc2006-04-23 03:47:58 +00001006- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1007 hex, octal, or binary; add ``append_const`` action; keep going if
1008 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1009 added ``epilog`` for better help generation).
1010
Tim Peters21fbd572006-04-21 21:18:10 +00001011- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1012 called from a thread spawned as a side effect of importing a module.
1013
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001014- The pydoc module now supports documenting packages contained in
1015 .zip or .egg files.
1016
1017- The pkgutil module now has several new utility functions, such
1018 as ``walk_packages()`` to support working with packages that are either
1019 in the filesystem or zip files.
1020
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001021- The mailbox module can now modify and delete messages from
1022 mailboxes, in addition to simply reading them. Thanks to Gregory
1023 K. Johnson for writing the code, and to the 2005 Google Summer of
1024 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001025
Tim Petersc7605f22006-04-17 21:12:33 +00001026- The ``__del__`` method of class ``local`` in module ``_threading_local``
1027 returned before accomplishing any of its intended cleanup.

1034
Anthony Baxtere29002c2006-04-12 12:07:31 +00001035- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1036 Windows. Bug #1469163.
1037
Phillip J. Eby47032112006-04-11 01:07:43 +00001038- The warnings, linecache, inspect, traceback, site, and doctest modules
1039 were updated to work correctly with modules imported from zipfiles or
1040 via other PEP 302 __loader__ objects.
1041
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001042- Patch #1467770: Reduce usage of subprocess._active to processes which
1043 the application hasn't waited on.

1048
Skip Montanaro262fb922006-04-21 02:31:07 +00001049- The pstats.Stats class accepts an optional stream keyword argument to
1050 direct output to an alternate file-like object.
1051
Anthony Baxter51bcb682006-04-05 14:51:42 +00001052Build
1053-----
1054
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001055- The Makefile now has a reindent target, which runs reindent.py on
1056 the library.
1057
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001058- Patch #1470875: Building Python with MS Free Compiler
1059
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001060- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001061
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001062- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1063 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001064 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001065 CXX from --with-cxx-main, see description in README.
1066
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001067- Patch #1429775: Link extension modules with the shared libpython.
1068
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001069- Fixed a libffi build problem on MIPS systems.
1070
Tim Peters8931ff12006-05-13 23:28:20 +00001071- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1072 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1073 and "%zu" for unsigned integers of type ``size_t``.
1074
Anthony Baxter51bcb682006-04-05 14:51:42 +00001075Tests
1076-----
1077
Nick Coghlanda2268f2006-04-24 04:37:15 +00001078- test_contextlib now checks contextlib.nested can cope with exceptions
1079 being raised and caught inside exit handlers.
1080
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001081- test_cmd_line now checks operation of the -m and -c command switches
1082
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001083- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1084 it separately and by hand. It also wasn't cleaning up its changes to
1085 the current Decimal context.
1086
Thomas Woutersabd08882006-04-26 15:53:30 +00001087- regrtest.py now has a -M option to run tests that test the new limits of
1088 containers, on 64-bit architectures. Running these tests is only sensible
1089 on 64-bit machines with more than two gigabytes of memory. The argument
1090 passed is the maximum amount of memory for the tests to use.

1099-------------
1100
Tim Petersb06d28c2006-05-12 01:57:59 +00001101- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1102
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001103- PEP 343: Added Context Types section to the library reference
1104 and attempted to bring other PEP 343 related documentation into
1105 line with the implementation and/or python-dev discussions.
1106
Tim Peters8dc73d22006-04-24 02:03:16 +00001107- Bug #1337990: clarified that ``doctest`` does not support examples
1108 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001111What's New in Python 2.5 alpha 1?
1112=================================
1113
Anthony Baxterebed3f62006-04-03 15:03:44 +00001114*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001115
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001116Core and builtins
1117-----------------
1118
Nick Coghlan43832302006-04-23 17:04:07 +00001119- PEP 338: -m command line switch now delegates to runpy.run_module
1120 allowing it to support modules in packages and zipfiles
1121
Martin v. Löwisc661b882006-04-20 04:54:23 +00001122- On Windows, .DLL is not an accepted file name extension for
1123 extension modules anymore; extensions are only found if they
1124 end in .PYD.
1125
Martin v. Löwisea62d252006-04-03 10:56:49 +00001126- Bug #1421664: sys.stderr.encoding is now set to the same value as
1127 sys.stdout.encoding.
1128
Neal Norwitz92e212f2006-04-03 04:48:37 +00001129- __import__ accepts keyword arguments.
1130
Georg Brandlccadf842006-03-31 18:54:53 +00001131- Patch #1460496: round() now accepts keyword arguments.
1132
Anthony Baxter262c00a2006-03-30 10:53:17 +00001133- Fixed bug #1459029 - unicode reprs were double-escaped.
1134
Hye-Shik Changd478f342006-03-23 12:32:36 +00001135- Patch #1396919: The system scope threads are reenabled on FreeBSD
1136 5.4 and later versions.
1137
Neal Norwitze98ccf62006-03-23 05:39:47 +00001138- Bug #1115379: Compiling a Unicode string with an encoding declaration
1139 now gives a SyntaxError.
1140
Georg Brandlabd1ff82006-03-18 07:59:59 +00001141- Previously, Python code had no easy way to access the contents of a
1142 cell object. Now, a ``cell_contents`` attribute has been added
1143 (closes patch #1170323).
1144
Tim Peterscf79aac2006-03-16 01:14:46 +00001145- Patch #1123430: Python's small-object allocator now returns an arena to
1146 the system ``free()`` when all memory within an arena becomes unused
1147 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1148 freed. Some applications will see a drop in virtual memory size now,
1149 especially long-running applications that, from time to time, temporarily
1150 use a large number of small objects. Note that when Python returns an
1151 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001152 platform C library will in turn return that memory to the operating system.
1153 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001154 appears to be effective at least on Microsoft C and gcc-based systems.
1155 Thanks to Evan Jones for hard work and patience.
1156
Georg Brandl533ff6f2006-03-08 18:09:27 +00001157- Patch #1434038: property() now uses the getter's docstring if there is
1158 no "doc" argument given. This makes it possible to legitimately use
1159 property() as a decorator to produce a read-only property.
1160
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001161- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1162 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1163 of requiring an int or long in slicing and a few other contexts, enabling
1164 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1165
Neal Norwitz995acdf2006-03-07 05:01:00 +00001166- Fixed various bugs reported by Coverity's Prevent tool.
1167
Brett Cannonbf364092006-03-01 04:25:17 +00001168- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1169 new exception base class, BaseException, which has a new message attribute.
1170 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1171 Raising a string exception now raises a DeprecationWarning.
1172
Thomas Woutersfb609f42006-02-28 16:37:25 +00001173- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1174 explicitly relative, using 'from .module import name' to mean 'from the same
1175 package as this module is in. Imports without dots still default to the
1176 old relative-then-absolute, unless 'from __future__ import
1177 absolute_import' is used.
1178
Brett Cannona7446e32006-02-27 23:39:10 +00001179- Properly check if 'warnings' raises an exception (usually when a filter set
1180 to "error" is triggered) when raising a warning for raising string
1181 exceptions.
1182
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001183- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001184 The name was removed from Include/code.h.
1185
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001186- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001187
Guido van Rossum1968ad32006-02-25 22:38:04 +00001188- Patch 1433928:
1189 - The copy module now "copies" function objects (as atomic objects).
1190 - dict.__getitem__ now looks for a __missing__ hook before raising
1191 KeyError.
1192
Tim Peters84ef21c2006-02-28 20:39:06 +00001193- PEP 343: with statement implemented. Needs ``from __future__ import
1194 with_statement``. Use of 'with' as a variable will generate a warning.
1195 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001196 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001197 The following objects have __context__ methods:
1198 - The built-in file type.
1199 - The thread.LockType type.
1200 - The following types defined by the threading module:
1201 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1202 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001203
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001204- Fix the encodings package codec search function to only search
1205 inside its own package. Fixes problem reported in patch #1433198.
1206
1207 Note: Codec packages should implement and register their own
1208 codec search function. PEP 100 has the details.
1209
Tim Peters9ea89d22006-06-04 03:26:02 +00001210- PEP 353: Using ``Py_ssize_t`` as the index type.
1211
1212- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1213 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1214 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1215 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1216 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001217
Neal Norwitzfc76d632006-01-10 06:03:13 +00001218- Patch #1400181, fix unicode string formatting to not use the locale.
1219 This is how string objects work. u'%f' could use , instead of .
1220 for the decimal point. Now both strings and unicode always use periods.
1221
Neal Norwitz671b9e32006-01-09 07:07:12 +00001222- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1223 configure would break checking curses.h.
1224
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001225- Bug #959576: The pwd module is now builtin. This allows Python to be
1226 built on UNIX platforms without $HOME set.
1227
Neal Norwitzc10978f2005-12-19 06:07:16 +00001228- Bug #1072182, fix some potential problems if characters are signed.
1229
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001230- Bug #889500, fix line number on SyntaxWarning for global declarations.
1231
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001232- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1233
Neal Norwitze7214a12005-12-18 05:03:17 +00001234- Support for converting hex strings to floats no longer works.
1235 This was not portable. float('0x3') now raises a ValueError.
1236
Barry Warsaw2a38a862005-12-18 01:27:35 +00001237- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001238 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001239 is now displayed in interactive prompt banner.
1240
Georg Brandlfa166682005-12-17 21:45:17 +00001241- Implementation of PEP 341 - Unification of try/except and try/finally.
1242 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001243 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001244
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001245- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1246 now encodes backslash correctly.
1247
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001248- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1249
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001250- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001251 and long longs.
1252
Neal Norwitz67715f02005-11-09 06:59:35 +00001253- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001254 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001255 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001256
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001257- Replaced most Unicode charmap codecs with new ones using the
1258 new Unicode translate string feature in the builtin charmap
1259 codec; the codecs were created from the mapping tables available
1260 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1261 encodings now include a mapping for the Apple logo)
1262
Tim Peterse3547fd2005-12-16 23:13:57 +00001263- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001264
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001265- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001266
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001267- A new AST parser implementation was completed. The abstract
1268 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001269 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001270
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001271- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001272 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1273
Neal Norwitz708e51a2005-10-03 04:48:15 +00001274- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1275
Neal Norwitz11bd1192005-10-03 00:54:56 +00001276- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1277 Provide a warning when a directory is passed on the command line.
1278
Neal Norwitz40d37812005-10-02 01:48:49 +00001279- Fix segfault with invalid coding.
1280
1281- SF bug #772896: unknown encoding results in MemoryError.
1282
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001283- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001284 supported a __len__() method which evaluated to False when the iterator
1285 was empty.
1286
Guido van Rossum630db602005-09-20 18:49:54 +00001287- On 64-bit platforms, when __len__() returns a value that cannot be
1288 represented as a C int, raise OverflowError.
1289
Skip Montanarof8948ca2005-09-19 03:54:46 +00001290- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001291 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001292
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001293- SF bug #893549: parsing keyword arguments was broken with a few format
1294 codes.
1295
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001296- Changes donated by Elemental Security to make it work on AIX 5.3
1297 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1298 bug #105470: test_pwd fails on 64bit system (Opteron).
1299
Guido van Rossum539c6622005-09-14 17:49:54 +00001300- Changes donated by Elemental Security to make it work on HP-UX 11 on
1301 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1302
Georg Brandl4550b8d2005-08-26 06:43:52 +00001303- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001304 (fixes bug #1119418).
1305
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001306- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1307
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001308- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1309 exceptions that cause a function to exit.
1310
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001311- The implementation of set() and frozenset() was revised to use its
1312 own internal data structure. Memory consumption is reduced by 1/3
1313 and there are modest speed-ups as well. The API is unchanged.
1314
Tim Petersde7990b2005-07-17 23:45:23 +00001315- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1316
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001317- SF bug #1229429: PyObject_CallMethod failed to decrement some
1318 reference counts in some error exit cases.
1319
Tim Petersecc6e6a2005-07-10 22:30:55 +00001320- SF bug #1185883: Python's small-object memory allocator took over
1321 a block managed by the platform C library whenever a realloc specified
1322 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001323 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001324 portable way to copy data from the C-managed block into Python's
1325 small-object space without risking a memory fault. Python's small-object
1326 realloc now leaves such blocks under the control of the platform C
1327 realloc.
1328
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001329- SF bug #1232517: An overflow error was not detected properly when
1330 attempting to convert a large float to an int in os.utime().
1331
Raymond Hettinger3296e692005-06-29 23:29:56 +00001332- SF bug #1224347: hex longs now print with lowercase letters just
1333 like their int counterparts.
1334
Michael W. Hudson188d4362005-06-20 16:52:57 +00001335- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1336 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1337 interpreter states; back out that fix and do a better job (see
1338 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1339 for a longer write-up of the problem).
1340
Michael W. Hudsondf888462005-06-03 14:41:55 +00001341- SF patch #1180995: marshal now uses a binary format by default when
1342 serializing floats.
1343
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001344- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1345 the routines that promise to produce IEEE 754 binary representations
1346 of floats now simply copy bytes around.
1347
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001348- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1349 278.
1350
Brett Cannonc3647ac2005-04-26 03:45:26 +00001351- patch #1109424: int, long, float, complex, and unicode now check for the
1352 proper magic slot for type conversions when subclassed. Previously the
1353 magic slot was ignored during conversion. Semantics now match the way
1354 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001355 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001356 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001357 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001358
Barry Warsawc8d907c2005-04-19 23:43:40 +00001359- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1360 NULL, now raise an AttributeError when attempting to set or delete the
1361 attribute. Previously a TypeError was raised, but this was inconsistent
1362 with the equivalent pure-Python implementation.
1363
Michael W. Hudson774479c2005-04-18 08:46:17 +00001364- It is now safe to call PyGILState_Release() before
1365 PyEval_InitThreads() (note that if there is reason to believe there
1366 are multiple threads around you still must call PyEval_InitThreads()
1367 before using the Python API; this fix is for extension modules that
1368 have no way of knowing if Python is multi-threaded yet).
1369
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001370- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1371 disabled caused a crash.
1372
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001373- Bug #1165306: instancemethod_new allowed the creation of a method
1374 with im_class == im_self == NULL, which caused a crash when called.
1375
Tim Petersecc6e6a2005-07-10 22:30:55 +00001376- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001377 fixes the crash seen in bug #1165761
1378
Raymond Hettinger96229b12005-03-11 06:49:40 +00001379- Added two new builtins, any() and all().
1380
Brett Cannon409d8f22005-03-05 06:47:57 +00001381- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001382 (e.g., ``class C(): pass`` is no longer a syntax error).
1383 Patch #1176012 added support to the 'parser' module and 'compiler' package
1384 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001385
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001386- Patch #1115086: Support PY_LONGLONG in structmember.
1387
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001388- Bug #1155938: new style classes did not check that __init__() was
1389 returning None.
1390
Tim Petersecc6e6a2005-07-10 22:30:55 +00001391- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001392 ('\') with a specific error message.
1393
Martin v. Löwisff232d72005-03-03 09:24:38 +00001394- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1395
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001396- Bug #1124295: the __name__ attribute of file objects was
1397 inadvertently made inaccessible in restricted mode.
1398
Tim Petersecc6e6a2005-07-10 22:30:55 +00001399- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001400 an ferror() call.
1401
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001402- min() and max() now support key= arguments with the same meaning as in
1403 list.sort().
1404
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001405- The peephole optimizer now performs simple constant folding in expressions:
1406 (2+3) --> (5).
1407
Raymond Hettingera422c342005-01-11 03:03:27 +00001408- set and frozenset objects can now be marshalled. SF #1098985.
1409
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001410- Bug #1077106: Poor argument checking could cause memory corruption
1411 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001412
Jeremy Hyltonab630502005-02-04 18:44:06 +00001413- The parser did not complain about future statements in illegal
1414 positions. It once again reports a syntax error if a future
1415 statement occurs after anything other than a doc string.
1416
Neil Schemenauercf52c072005-08-12 17:34:58 +00001417- Change the %s format specifier for str objects so that it returns a
1418 unicode instance if the argument is not an instance of basestring and
1419 calling __str__ on the argument returns a unicode instance.
1420
Tim Petersf4e69282006-02-27 17:15:31 +00001421- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1422 current thread state when the auto-GIL-state machinery knows about
1423 it (since the thread state is being deleted, continuing to remember it
1424 can't help, but can hurt if another thread happens to get created with
1425 the same thread id).
1426
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001427Extension Modules
1428-----------------
1429
Georg Brandl43f08a82006-03-31 18:01:16 +00001430- Patch #1380952: fix SSL objects timing out on consecutive read()s
1431
Neal Norwitz05a45592006-03-20 06:30:08 +00001432- Patch #1309579: wait3 and wait4 were added to the posix module.
1433
Anthony Baxterfa869072006-03-20 05:21:58 +00001434- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1435 In addition, the existing ulaw code was updated.
1436
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001437- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001438 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001439
Neal Norwitz10be10c2006-03-16 06:50:13 +00001440- Everything under lib-old was removed. This includes the following modules:
1441 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001442 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001443 util, whatsound, whrandom, zmod
1444
1445- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1446
1447- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001448 is deprecated. The undocumented re.engine variable no longer exists.
1449
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001450- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1451 SS2 (single-shift 2) escape sequences correctly.
1452
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001453- The unicodedata module was updated to the 4.1 version of the Unicode
1454 database. The 3.2 version is still available as unicodedata.db_3_2_0
1455 for applications that require this specific version (such as IDNA).
1456
Neal Norwitzb62c4332006-03-04 18:35:47 +00001457- The timing module is no longer built by default. It was deprecated
1458 in PEP 4 in Python 2.0 or earlier.
1459
Guido van Rossum1968ad32006-02-25 22:38:04 +00001460- Patch 1433928: Added a new type, defaultdict, to the collections module.
1461 This uses the new __missing__ hook behavior added to dict (see above).
1462
Georg Brandldbd83392006-02-20 09:42:33 +00001463- Bug #854823: socketmodule now builds on Sun platforms even when
1464 INET_ADDRSTRLEN is not defined.
1465
Georg Brandlf4f44152006-02-18 22:29:33 +00001466- Patch #1393157: os.startfile() now has an optional argument to specify
1467 a "command verb" to invoke on the file.
1468
Neal Norwitz082b2df2006-02-07 07:04:46 +00001469- Bug #876637, prevent stack corruption when socket descriptor
1470 is larger than FD_SETSIZE.
1471
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001472- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1473 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1474 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1475
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001476- Patch #1422385: The nis module now supports access to domains other
1477 than the system default domain.
1478
Martin v. Löwis14694662006-02-03 12:54:16 +00001479- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1480 are reported, the limit on path name lengths is removed, and stat reports
1481 WindowsError now (instead of OSError).

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001617- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1618 been renamed to have only a single underscore prefix. This was done to
1619 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001620
Nick Coghlan43832302006-04-23 17:04:07 +00001621- PEP 338: new module runpy defines a run_module function to support
1622 executing modules which provide access to source code or a code object
1623 via the PEP 302 import mechanisms.
1624
Anthony Baxter93f5b932006-04-03 08:05:07 +00001625- The email module's parsedate_tz function now sets the daylight savings

1633 in attribute values.
1634
Anthony Baxterc51ee692006-04-01 00:57:31 +00001635- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001636 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001637 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001638 module will not be built.
1639
Tim Petersc17976e2006-04-01 00:26:53 +00001640- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1641 aren't officially supported here, and trying to use them will probably
1642 raise an exception some day. But dicts have been allowed, and "mostly
1643 worked", so support for them won't go away without warning.
1644
Georg Brandl338ef7d2006-03-31 18:42:16 +00001645- Bug #1445068: getpass.getpass() can now be given an explicit stream

1663
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001664- email 4.0 package now integrated. This is largely the same as the email 3.0
1665 package that was included in Python 2.3, except that PEP 8 module names are
1666 now used (e.g. mail.message instead of email.Message). The MIME classes
1667 have been moved to a subpackage (e.g. email.mime.text instead of
1668 email.MIMEText). The old names are still supported for now. Several
1669 deprecated Message methods have been removed and lots of bugs have been
1670 fixed. More details can be found in the email package documentation.
1671
Walter Dörwald40108c92006-03-27 08:15:44 +00001672- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1673 (a subclass of tuple) that provides incremental decoders and encoders
1674 (a way to use stateful codecs without the stream API). Python functions
1675 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1676 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1677 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001679- Patch #1359365: Calling next() on a closed StringIO.String object raises
1680 a ValueError instead of a StopIteration now (like file and cString.String do).
1681 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1682 called before (like file and StringIO.StringIO do).

1750
Neal Norwitz338e7862005-12-23 21:27:46 +00001751- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
1752 LoadError as documented, instead of IOError. For compatibility,
1753 LoadError subclasses IOError.
1754
Brett Cannon3cbd0382005-12-16 22:49:23 +00001755- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001756 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1757 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1758 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1759 Ronald L. Rivest offered this advice for Python:
1760
1761 "The consensus of researchers in this area (at least as
1762 expressed at the NIST Hash Function Workshop 10/31/05),
1763 is that SHA-256 is a good choice for the time being, but
1764 that research should continue, and other alternatives may
1765 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001766
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001767- Added a subset of Fredrik Lundh's ElementTree package. Available

Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001811 separator and do not output trailing semicolon.
Georg Brandl532efab2005-08-24 22:34:21 +00001812
Georg Brandlb9256022005-08-24 18:46:39 +00001813- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
1814 ContentTooShortException, when the actually downloaded size does not
1815 match the Content-Length header.
1816

1820 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001821 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001822

1836
Georg Brandla4a8b822005-07-15 09:13:21 +00001837- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
1838 parameter, but uses the usual "kwargs=None".
1839
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001840- textwrap now processes text chunks at O(n) speed instead of O(n**2).

1844 to W3C name (404 -> 'Not Found'). RFE #1216944.
1845
Georg Brandl9e43acf2005-07-04 17:16:07 +00001846- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1847 as this can cause problems with apps closing all file descriptors.

1860 Bug #1224621.
1861
Raymond Hettinger68c04532005-06-10 11:05:19 +00001862- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001863 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001864 the generate_tokens() function now accepts a callable argument that
1865 terminates by raising StopIteration.
1866
Georg Brandl9166e1a2005-06-04 09:20:03 +00001867- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1875 class at all.
1876
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001877- distutils.commands.upload was added to support uploading distribution

1881 them to PyPI.
1882
Raymond Hettinger267b8682005-03-27 10:47:39 +00001883- decimal operator and comparison methods now return NotImplemented
1884 instead of raising a TypeError when interacting with other types. This
1885 allows other classes to implement __radd__ style methods and have them
1886 work as expected.
1887
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001888- Bug #1163325: Decimal infinities failed to hash. Attempting to
1889 hash a NaN raised an InvalidOperation instead of a TypeError.
1890
Tim Petersecc6e6a2005-07-10 22:30:55 +00001891- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1904
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001905- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1906

1925
Guido van Rossumd0641422005-02-03 15:01:24 +00001926- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1927 disables recursive traversal through instance attributes, which can
1928 be exploited in various ways.
1929
Tim Peterse3547fd2005-12-16 23:13:57 +00001930- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001931 flags on the HTTP listening socket.
1932
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001933- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1934 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1935
Fred Drakefbdeaad2006-07-29 16:56:15 +00001936- Patches #893642, #1039083: add allow_none, encoding arguments to
1937 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001938

1942
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001943- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1944
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001945- Enhancements to the csv module:
1946
1947 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001948 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001949 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001950 + Dialect parameter parsing has been re-implemented to improve error
1951 reporting.
1952 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1953 dictates.
1954 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001955 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001956 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001957 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1958 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001959 + reader now allows \r characters to be quoted (previously it only allowed
1960 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001961 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001962 + Dialect classes passed to the module are no longer instantiated by
1963 the module before being parsed (the former validation scheme required
1964 this, but the mechanism was unreliable).
1965 + The dialect registry now contains instances of the internal
1966 C-coded dialect type, rather than references to python objects.
1967 + the internal c-coded dialect type is now immutable.
1968 + register_dialect now accepts the same keyword dialect specifications
1969 as the reader and writer, allowing the user to register dialects
1970 without first creating a dialect class.
1971 + a configurable limit to the size of parsed fields has been added -
1972 previously, an unmatched quote character could result in the entire
1973 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001974 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001975 the parser field size limit (returning the former limit). The initial
1976 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001977 + A line_num attribute has been added to the reader object, which tracks
1978 the number of lines read from the source iterator. This is not
1979 the same as the number of records returned, as records can span
1980 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001981 + reader and writer objects were not being registered with the cyclic-GC.
1982 This has been fixed.
1983
Brett Cannone6539c42005-01-08 02:43:53 +00001984- _DummyThread objects in the threading module now delete self.__block that is
1985 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1986 lock primitives tend to be limited in number and thus should not be wasted on
1987 a _DummyThread object. Fixes bug #1089632.
1988
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001989- The imghdr module now detects Exif files.
1990
Raymond Hettinger6065d322004-12-20 23:51:53 +00001991- StringIO.truncate() now correctly adjusts the size attribute.
1992 (Bug #951915).
1993
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001994- locale.py now uses an updated locale alias table (built using
1995 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1996 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001997 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001998
Raymond Hettinger3557f422004-12-07 12:02:02 +00001999- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2000
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002001- the pickle module no longer accepts the deprecated None option in the
2002 args tuple returned by __reduce__().
2003
Brett Cannon84667c02004-12-07 03:25:18 +00002004- optparse now optionally imports gettext. This allows its use in setup.py.
2005
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002006- the pickle module no longer uses the deprecated bin parameter.
2007

2013
Raymond Hettinger664347b2004-12-04 21:21:53 +00002014- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2015 extended or overridden by subclasses. Formerly, the subclassed method would
2016 be ignored by the rest of the module. (Bug #1078905).
2017
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002018- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002019 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002020
Walter Dörwald36733692004-12-22 12:50:50 +00002021- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2022 once when a size argument is given. This prevents a buffer overflow in the
2023 tokenizer with very long source lines.
2024
Barry Warsaw538561e2006-01-01 21:48:54 +00002025- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2026 immediately after creating the object, without any intervening
2027 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002028
Skip Montanaro05885812005-01-16 20:48:27 +00002029- The reconvert.quote function can now emit triple-quoted strings. The
2030 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002031
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002032- ``UserString.MutableString`` now supports negative indices in
2033 ``__setitem__`` and ``__delitem__``
2034
Greg Ward40407942005-03-05 02:53:17 +00002035- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2036 correctly.
2037
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002038- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2039 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2040 character even if the user has passed a size parameter to get a proper
2041 line ending. Remove the special handling of a "\r\n" that has been split
2042 between two lines.
2043
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002044- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2045 about illegal code points. The codec now supports PEP 293 style error
2046 handlers.
2047
Walter Dörwald78a78b02005-09-01 12:04:29 +00002048- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002049 from the input stream, so that the output is a byte string in the correct
2050 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002051
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002052- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2053 considering it exactly like a '*'.
2054
Walter Dörwald007f8df2005-10-09 19:42:27 +00002055- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2056 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002057
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002058- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2059
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002060- Patch #1413711: Certain patterns of differences were making difflib
2061 touch the recursion limit.
2062
Walter Dörwald58917a62006-03-31 15:26:22 +00002063- Bug #947906: An object oriented interface has been added to the calendar
2064 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002065 called as a script (e.g. via ``python -mcalendar``). Localized month and
2066 weekday names can be ouput (even if an exotic encoding is used) using
2067 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002069Build
2070-----
2071
Neal Norwitz602d3392006-03-31 08:21:40 +00002072- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2073 by using -mieee gcc option.
2074

2076
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002077- Build support for Win64-AMD64 was added.
2078
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002079- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2080
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002081- Patch #881820: look for openpty and forkpty also in libbsd.
2082
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002083- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2084 The zlib module is now builtin on Windows.
2085
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002086- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2087
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002088- Bug #1189330: configure did not correctly determine the necessary
2089 value of LINKCC if python was built with GCC 4.0.
2090
Trent Mick8321b422005-07-26 02:29:21 +00002091- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2092 vulnerability in zlib 1.2.1 and 1.2.2.
2093
Brett Cannon08cd5982005-04-24 22:26:38 +00002094- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2095 flags that change binary compatibility. Changes were also made to
2096 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002097 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002098
Bob Ippolitoed233462005-03-29 13:47:59 +00002099- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2100 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2101 no longer exists). This configure patch makes things right.
2102
Martin v. Löwise2713be2005-03-08 15:03:08 +00002103- Bug #1158607: Build with --disable-unicode again.
2104
Brett Cannon46d96232005-02-16 00:07:19 +00002105- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2106 defined. Discovered as a result of not being able to build on OS X.
2107
Brett Cannon516592f2004-12-07 00:42:59 +00002108- setup.py now uses the directories specified in LDFLAGS using the -L option
2109 and in CPPFLAGS using the -I option for adding library and include
2110 directories, respectively, for compiling extension modules against. This has
2111 led to the core being compiled using the values in CPPFLAGS. It also removes
2112 the need for the special-casing of both DarwinPorts and Fink for darwin since
2113 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2114 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2115 Fink, ``-I/opt/local/include`` for DarwinPorts).
2116
Brett Cannon43802422005-02-10 20:48:03 +00002117- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2118 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2119 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2120 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002122C API
2123-----
2124
Tim Petersc9d78aa2006-03-26 23:27:58 +00002125- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2126 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2127 is obtained via the ``PyObject_`` family, it must be released via the
2128 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2129 always been officially true, but when Python's small-object allocator was
2130 introduced, an attempt was made to cater to a few extension modules
2131 discovered at the time that obtained memory via ``PyObject_New`` but
2132 released it via ``PyMem_DEL``. It's years later, and if such code still
2133 exists it will fail now (probably with segfaults, but calling wrong
2134 low-level memory management functions can yield many symptoms).
2135
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002136- Added a C API for set and frozenset objects.
2137

2139
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002140- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2141 mapping argument now. This string is used as a mapping table. Byte values
2142 greater than the length of the string and 0xFFFE are treated as undefined
2143 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002149- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002150
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002151- Patch #1276356: New resource "urlfetch" is implemented. This enables
2152 even impatient people to run tests that require remote files.
