13-----------------
14
Georg Brandlec6c2df2006-09-11 09:38:35 +000015- Make _PyGILState_NoteThreadState() static, it was not used anywhere

33 head is the original string if sep was not found.
34
Neal Norwitzdac090d2006-09-05 03:53:08 +000035- Bug #1520864: unpacking singleton tuples in list comprehensions and
36 generator expressions (x for x, in ... ) works again. Fixing this problem
37 required changing the .pyc magic number. This means that .pyc files
38 generated before 2.5c2 will be regenerated.
39
Neal Norwitzca460d92006-09-06 06:28:06 +000040- with and as are now keywords.

Guido van Rossumc69ac252006-08-10 18:09:25 +0000118What's New in Python 2.5 release candidate 1?
119=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000120
Anthony Baxterb4096662006-08-16 03:42:26 +0000121*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000122
123Core and builtins
124-----------------
125
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000126- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000127 compared equal or unequal to a string and a UnicodeDecodeError
128 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000129
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000130 Instead, the equal (==) and unequal (!=) comparison operators will
131 now issue a UnicodeWarning and interpret the two objects as
132 unequal. The UnicodeWarning can be filtered as desired using
133 the warning framework, e.g. silenced completely, turned into an
134 exception, logged, etc.
135
136 Note that compare operators other than equal and unequal will still
137 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000138
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000139- Fix segfault when doing string formatting on subclasses of long.
140
141- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
142 with new-style classes.
143
144- Fix bug related to __len__ functions returning negative values with
145 classic classes.
146
147- Patch #1538606, Fix __index__() clipping. There were some problems
148 discovered with the API and how integers that didn't fit into Py_ssize_t
149 were handled. This patch attempts to provide enough alternatives
150 to effectively use __index__.
151
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000152- Bug #1536021: __hash__ may now return long int; the final hash
153 value is obtained by invoking hash on the long int.
154
Thomas Hellerab1049c2006-08-08 17:37:00 +0000155- Bug #1536786: buffer comparison could emit a RuntimeWarning.
156
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000157- Bug #1535165: fixed a segfault in input() and raw_input() when
158 sys.stdin is closed.
159
Thomas Heller74d36f02006-08-04 18:17:40 +0000160- On Windows, the PyErr_Warn function is now exported from
161 the Python dll again.
162
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000163- Bug #1191458: tracing over for loops now produces a line event
164 on each iteration. Fixing this problem required changing the .pyc
165 magic number. This means that .pyc files generated before 2.5c1
166 will be regenerated.
167
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000168- Bug #1333982: string/number constants were inappropriately stored
169 in the byte code and co_consts even if they were not used, ie
170 immediately popped off the stack.
171
Georg Brandle9462c72006-08-04 18:03:37 +0000172- Fixed a reference-counting problem in property().
173
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000174
175Library
176-------
177
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000178- Fix a bug in the ``compiler`` package that caused invalid code to be
179 generated for generator expressions.
180
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000181- The distutils version has been changed to 2.5.0. The change to
182 keep it programmatically in sync with the Python version running
183 the code (introduced in 2.5b3) has been reverted. It will continue
184 to be maintained manually as static string literal.
185
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000186- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000187 and this cannot be converted to the required C type, an exception is
188 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000189 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000190
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000191- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000192 an exception.
193
Tim Petersc10c9d02006-09-05 02:18:09 +0000194- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000195 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000196 workarounds for clocks with low resolution, to stop the code yielding
197 duplicate UUIDs.
198
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000199- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
200 before raising SystemExit, allowing IDLE to honor quit() and exit().
201
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000202- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
203
Georg Brandl7a1af772006-08-14 21:55:28 +0000204- Patch #1536071: trace.py should now find the full module name of a
205 file correctly even on Windows.
206
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000207- logging's atexit hook now runs even if the rest of the module has
208 already been cleaned up.
209
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000210- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000211
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000212- Bug #1531405, format_exception no longer raises an exception if
213 str(exception) raised an exception.
214
Neil Schemenauer06ded092006-08-04 16:20:30 +0000215- Fix a bug in the ``compiler`` package that caused invalid code to be
216 generated for nested functions.

225 raises the correct exceptions.
226
Thomas Heller1ce433e2006-08-14 16:20:04 +0000227- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
228 '-no-stack-protector' compiler flag for OpenBSD has been removed.
229
Thomas Heller86720042006-08-14 11:17:48 +0000230- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
231 uses the _as_parameter_ attribute when objects are passed to foreign
232 function calls. The ctypes version number was changed to 1.0.1.
233
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000234- Bug #1530559, struct.pack raises TypeError where it used to convert.
235 Passing float arguments to struct.pack when integers are expected
236 now triggers a DeprecationWarning.

286Core and builtins
287-----------------
288
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000289- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000290 returned a long (see PEP 353).
291
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000292- Bug #1515471: string.replace() accepts character buffers again.
293
Neal Norwitz07aadb12006-07-30 06:55:48 +0000294- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
295 This provides the proper warning for struct.pack().
296 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
297
Neal Norwitz0d62a062006-07-30 06:53:31 +0000298- Patch #1531113: Fix augmented assignment with yield expressions.
299 Also fix a SystemError when trying to assign to yield expressions.
300
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000301- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
302 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
303 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
304 excessive filesystem operations during imports.
305
Tim Petersbc24eee2006-07-27 01:14:53 +0000306- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
307 operations on signed longs that are formally undefined by C.
308 Unfortunately, at least one compiler now cares about that, so complicated
309 the code to make that compiler happy again.
310
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000311- Bug #1524310: Properly report errors from FindNextFile in os.listdir.

Martin v. Löwisd22968a2006-07-24 11:54:53 +0000313- Patch #1232023: Stop including current directory in search
314 path on Windows.
315
Neal Norwitze1fdb322006-07-21 05:32:28 +0000316- Fix some potential crashes found with failmalloc.
317
Neal Norwitze7563102006-07-17 01:00:16 +0000318- Fix warnings reported by Klocwork's static analysis tool.
319
Neal Norwitz84be93b2006-07-16 01:50:38 +0000320- Bug #1512814, Fix incorrect lineno's when code within a function
321 had more than 255 blank lines.
322
Georg Brandl9dceedb2006-07-12 15:31:17 +0000323- Patch #1521179: Python now accepts the standard options ``--help`` and
324 ``--version`` as well as ``/?`` on Windows.
325
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000326- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000327 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000328 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000329
Tim Peters112aad32006-07-19 00:03:19 +0000330- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000331 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000332 new ``sys._current_frames()`` returns a dictionary with one entry,
333 mapping the faux "thread id" 0 to the current frame.
334
Ronald Oussoren3075e162006-07-25 20:28:55 +0000335- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

339-------
340
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000341- Correction of patch #1455898: In the mbcs decoder, set final=False
342 for stream decoder, but final=True for the decode function.
343
Georg Brandl07fec3a2006-08-01 18:49:24 +0000344- os.urandom no longer masks unrelated exceptions like SystemExit or
345 KeyboardInterrupt.
346
Tim Peters4643c2f2006-08-10 22:45:34 +0000347- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000348 shutil.copytree on Windows
349
Georg Brandle34ac7c2006-07-30 11:07:23 +0000350- Bug #1002398: The documentation for os.path.sameopenfile now correctly
351 refers to file descriptors, not file objects.
352
Tim Petersc10c9d02006-09-05 02:18:09 +0000353- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000354 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000355 #1513611, and probably others.
356
Georg Brandledd9b0d2006-07-29 09:33:26 +0000357- Bug #1441397: The compiler module now recognizes module and function
358 docstrings correctly as it did in Python 2.4.
359
Tim Peters6f681472006-07-27 23:44:37 +0000360- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
361 lost that tests are sorted by name before being run. This rarely
362 matters for well-written tests, but can create baffling symptoms if
363 side effects from one test to the next affect outcomes. ``DocTestFinder``
364 has been changed to sort the list of tests it returns.
365
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000366- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000367 in sync with sys.version_info[:3].

Georg Brandl8c036cc2006-08-20 13:15:39 +0000371- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
372 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000373
Georg Brandlcf0c1722006-07-26 07:23:32 +0000374- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
375 to recursive calls and call it with the failing package name.
376
Martin v. Löwis0b483032006-07-25 09:53:12 +0000377- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
378
Georg Brandlc13c34c2006-07-24 14:09:56 +0000379- Patch #1515343: Fix printing of deprecated string exceptions with a
380 value in the traceback module.
381
Greg Ward48fae7a2006-07-23 16:05:51 +0000382- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
383
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000384- Patch #1524429: Use repr() instead of backticks in Tkinter again.
385
Brett Cannoncaebe222006-07-18 04:41:36 +0000386- Bug #1520914: Change time.strftime() to accept a zero for any position in its
387 argument tuple. For arguments where zero is illegal, the value is forced to
388 the minimum value that is correct. This is to support an undocumented but
389 common way people used to fill in inconsequential information in the time
390 tuple pre-2.4.
391
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000392- Patch #1220874: Update the binhex module for Mach-O.
393
Barry Warsawb110bad2006-07-21 14:51:07 +0000394- The email package has improved RFC 2231 support, specifically for
395 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
396 (name*0=<blah>) parameter continuations. This may change the types of
397 values returned from email.message.Message.get_param() and friends.
398 Specifically in some cases where non-encoded continuations were used,
399 get_param() used to return a 3-tuple of (None, None, string) whereas now it
400 will just return the string (since non-encoded continuations don't have
401 charset and language parts).
402
403 Also, whereas % values were decoded in all parameter continuations, they are
404 now only decoded in encoded parameter parts.
405
Ronald Oussoren3075e162006-07-25 20:28:55 +0000406- Bug #1517990: IDLE keybindings on MacOS X now work correctly
407
408- Bug #1517996: IDLE now longer shows the default Tk menu when a
409 path browser, class browser or debugger is the frontmost window on MacOS X
410
Barry Warsaw00decd72006-07-27 23:43:15 +0000411- Patch #1520294: Support for getset and member descriptors in types.py,
412 inspect.py, and pydoc.py. Specifically, this allows for querying the type
413 of an object against these built-in types and more importantly, for getting
414 their docstrings printed in the interactive interpreter's help() function.

418-----------------
419
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000420- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
421 a socket operation on a socket with a timeout, the exception will be
422 caught correctly. Previously, the exception was not caught.
423
Thomas Heller1393d6a2006-07-28 21:43:20 +0000424- Patch #1529514: The _ctypes extension is now compiled on more
425 openbsd target platforms.
426
Tim Peters9cab5932006-07-28 00:30:00 +0000427- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
428 a memory leak, affecting pickles and deep copies.
429
Tim Petersbc24eee2006-07-27 01:14:53 +0000430- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

432
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000433- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
434
Thomas Hellerce049a02006-07-14 17:51:14 +0000435- Patch #1521817: Index range checking on ctypes arrays containing
436 exactly one element enabled again. This allows iterating over these
437 arrays, without the need to check the array size before.
438
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000439- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000440 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000441 /dev/null in certain cases; this is now fixed.
442
Thomas Heller47d7a062006-07-12 08:43:47 +0000443- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
444 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000445
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000446- Because of a misspelled preprocessor symbol, ctypes was always
447 compiled without thread support; this is now fixed.
448
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000449- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
450 methods now allow their database parameter to be None as the
451 sleepycat API allows.
452
Matt Flemingec926502006-07-28 11:27:27 +0000453- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
454 bluetooth API compared with Linux and FreeBSD.
455
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000456Tests
457-----
458
459- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
460 how long the test file should take to play. Now accepts taking 2.93 secs
461 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
462
Georg Brandl4793aa32006-07-28 18:31:39 +0000463- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
464 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
465 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000472Mac
473---
474
475- PythonLauncher now works correctly when the path to the script contains
476 characters that are treated specially by the shell (such as quotes).
477
478- Bug #1527397: PythonLauncher now launches scripts with the working directory
479 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000480 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000481 expect.

490-----------------
491
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000492- Bug #1441486: The literal representation of -(sys.maxint - 1)
493 again evaluates to a int object, not a long.
494
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000495- Bug #1501934: The scope of global variables that are locally assigned
496 using augmented assignment is now correctly determined.
497
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000498- Bug #927248: Recursive method-wrapper objects can now safely
499 be released.
500
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000501- Bug #1417699: Reject locale-specific decimal point in float()
502 and atof().
503
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000504- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
505 omit a default "error" argument for NULL pointer. This allows
506 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000507
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000508- Bug #1519018: 'as' is now validated properly in import statements.
509
Neal Norwitz28746ab2006-07-09 22:14:42 +0000510- On 64 bit systems, int literals that use less than 64 bits are
511 now ints rather than longs.
512
Neal Norwitzed657552006-07-10 00:04:44 +0000513- Bug #1512814, Fix incorrect lineno's when code at module scope
514 started after line 256.
515
Tim Peters32a83612006-07-10 21:08:24 +0000516- New function ``sys._current_frames()`` returns a dict mapping thread
517 id to topmost thread stack frame. This is for expert use, and is
518 especially useful for debugging application deadlocks. The functionality
519 was previously available in Fazal Majid's ``threadframe`` extension
520 module, but it wasn't possible to do this in a wholly threadsafe way from
521 an extension.

538
Thomas Woutersadd19112006-07-05 11:03:49 +0000539- string.Template() now correctly handles tuple-values. Previously,
540 multi-value tuples would raise an exception and single-value tuples would
541 be treated as the value they contain, instead.
542
Martin v. Löwisede77f52006-07-03 13:01:35 +0000543- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

550 degrees and radians.
551
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000552- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000553 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000554
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000555- Bug #1514703: Only setup canvas window in turtle when the canvas
556 is created.
557
Martin v. Löwis7596e832006-07-01 15:33:37 +0000558- Bug #1513223: .close() of a _socketobj now releases the underlying
559 socket again, which then gets closed as it becomes unreferenced.
560
Fred Drake10497c82006-06-29 02:57:48 +0000561- Bug #1504333: Make sgmllib support angle brackets in quoted
562 attribute values.
563
564- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
565 sgmllib ('[' and ']' were not accepted).
566
Georg Brandl1be63af2006-06-28 20:23:25 +0000567- Fix a bug in the turtle module's end_fill function.
568
Brett Cannon53ab5b72006-06-22 16:49:14 +0000569- Bug #1510580: The 'warnings' module improperly required that a Warning
570 category be either a types.ClassType and a subclass of Warning. The proper
571 check is just that it is a subclass with Warning as the documentation states.
572
Georg Brandlad29e632006-06-21 17:45:17 +0000573- The compiler module now correctly compiles the new try-except-finally
574 statement (bug #1509132).
575
Neal Norwitz60373cd2006-06-22 06:30:50 +0000576- The wsgiref package is now installed properly on Unix.
577
Vinay Sajip28e57612006-07-01 10:45:20 +0000578- A bug was fixed in logging.config.fileConfig() which caused a crash on
579 shutdown when fileConfig() was called multiple times.
580
Gerhard Häring762fbd32006-07-02 17:48:30 +0000581- The sqlite3 module did cut off data from the SQLite database at the first
582 null character before sending it to a custom converter. This has been fixed
583 now.

587
Tim Peters112aad32006-07-19 00:03:19 +0000588- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
589 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
590 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000591
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000592- Assigning None to pointer type fields in ctypes structures possible
593 overwrote the wrong fields, this is fixed now.
594
595- Fixed a segfault in _ctypes when ctypes.wintypes were imported
596 on non-Windows platforms.
597
598- Bug #1518190: The ctypes.c_void_p constructor now accepts any
599 integer or long, without range checking.
600
601- Patch #1517790: It is now possible to use custom objects in the ctypes
602 foreign function argtypes sequence as long as they provide a from_param
603 method, no longer is it required that the object is a ctypes type.
604
605- The '_ctypes' extension module now works when Python is configured
606 with the --without-threads option.
607
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000608- Bug #1513646: os.access on Windows now correctly determines write
609 access, again.
610
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000611- Bug #1512695: cPickle.loads could crash if it was interrupted with

623
Tim Peters32a83612006-07-10 21:08:24 +0000624- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000625 Previously, the slight difference could cause compilation errors of the
626 'zlib' module on systems with more than one version of zlib.
627
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000628- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +0000656
Anthony Baxterd1136802006-06-19 12:04:15 +0000657*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000658
659Core and builtins
660-----------------
661
Georg Brandla56b9152006-06-19 06:35:54 +0000662- Patch #1507676: Error messages returned by invalid abstract object operations
663 (such as iterating over an integer) have been improved and now include the
664 type of the offending object to help with debugging.
665
Brett Cannonea3912b2006-06-13 21:46:41 +0000666- Bug #992017: A classic class that defined a __coerce__() method that returned
667 its arguments swapped would infinitely recurse and segfault the interpreter.
668
Neal Norwitz909eb122006-06-12 02:13:21 +0000669- Fix the socket tests so they can be run concurrently.
670
Neal Norwitzb9845e72006-06-12 02:11:18 +0000671- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000672 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000673
Brett Cannon22565aa2006-06-09 22:31:23 +0000674- Bug #532646: object.__call__() will continue looking for the __call__
675 attribute on objects until one without one is found. This leads to recursion
676 when you take a class and set its __call__ attribute to an instance of the
677 class. Originally fixed for classic classes, but this fix is for new-style.
678 Removes the infinite_rec_3 crasher.
679
Georg Brandl24250812006-06-09 18:45:48 +0000680- The string and unicode methods startswith() and endswith() now accept
681 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
682
Brett Cannonde3b0522006-06-08 17:00:45 +0000683- Buffer objects, at the C level, never used the char buffer
684 implementation even when the char buffer for the wrapped object was
685 explicitly requested (originally returned the read or write buffer).
686 Now a TypeError is raised if the char buffer is not present but is
687 requested.
688
Georg Brandlddbaa662006-06-04 21:56:52 +0000689- Patch #1346214: Statements like "if 0: suite" are now again optimized
690 away like they were in Python 2.4.
691
Georg Brandlb7c8f542006-05-27 12:30:25 +0000692- Builtin exceptions are now full-blown new-style classes instead of
693 instances pretending to be classes, which speeds up exception handling
694 by about 80% in comparison to 2.5a2.
695
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000696- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
697 Unicode 4.1.
698
Georg Brandlf4ef1162006-05-26 18:03:31 +0000699- Patch #921466: sys.path_importer_cache is now used to cache valid and
700 invalid file paths for the built-in import machinery which leads to
701 fewer open calls on startup.
702
Tim Peters696cf432006-05-24 21:10:40 +0000703- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
704 of-2 bases. The largest speedup is for inputs with about 1000 decimal
705 digits. Conversion from non-power-of-2 bases remains quadratic-time in
706 the number of input digits (it was and remains linear-time for bases
707 2, 4, 8, 16 and 32).
708
Tim Petersb713ec22006-05-23 18:45:30 +0000709- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
710 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
711 an integer close to ``sys.maxint``. This was repaired by patch
712 #1335972, which also gives a nice speedup.
713
Richard Jonescebbefc2006-05-23 18:28:17 +0000714- Patch #1337051: reduced size of frame objects.
715
716- PyErr_NewException now accepts a tuple of base classes as its
717 "base" parameter.
718
Richard Jones7c88dcc2006-05-23 10:37:38 +0000719- Patch #876206: function call speedup by retaining allocated frame
720 objects.
721
Georg Brandl7b90e162006-05-18 07:01:27 +0000722- Bug #1462152: file() now checks more thoroughly for invalid mode
723 strings and removes a possible "U" before passing the mode to the
724 C library function.
725
Neal Norwitz1004a532006-05-15 07:17:23 +0000726- Patch #1488312, Fix memory alignment problem on SPARC in unicode
727
Neal Norwitz373f0a72006-05-15 07:04:36 +0000728- Bug #1487966: Fix SystemError with conditional expression in assignment
729
Martin v. Löwis879768d2006-05-11 13:28:43 +0000730- WindowsError now has two error code attributes: errno, which carries
731 the error values from errno.h, and winerror, which carries the error
732 values from winerror.h. Previous versions put the winerror.h values
733 (from GetLastError()) into the errno attribute.
734
Martin v. Löwis77736712006-05-04 05:51:03 +0000735- Patch #1475845: Raise IndentationError for unexpected indent.
736
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000737- Patch #1479181: split open() and file() from being aliases for each other.
738
Tim Peters44bd9862006-06-01 13:49:23 +0000739- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
740 methods were always silently ignored by dictionaries when comparing keys.
741 They are now passed through (except when using the C API function
742 ``PyDict_GetItem()``, whose semantics did not change).
743
744- Bug #1456209: In some obscure cases it was possible for a class with a
745 custom ``__eq__()`` method to confuse dict internals when class instances
746 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
747 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000749Extension Modules
750-----------------
751

753
754- Patch #1462338: Upgrade pyexpat to expat 2.0.0
755
Brett Cannon6ee7d012006-06-08 16:23:04 +0000756- Change binascii.hexlify to accept a read-only buffer instead of only a char
757 buffer and actually follow its documentation.
758
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000759- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
760
Nick Coghlanc649ec52006-05-29 12:43:05 +0000761- Patch #1478788 (modified version): The functional extension module has
762 been renamed to _functools and a functools Python wrapper module added.
763 This provides a home for additional function related utilities that are
764 not specifically about functional programming. See PEP 309.
765
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000766- Patch #1493701: performance enhancements for struct module.
767
Georg Brandl378d5922006-05-17 14:26:50 +0000768- Patch #1490224: time.altzone is now set correctly on Cygwin.
769
Georg Brandl8d3342b2006-05-16 07:38:27 +0000770- Patch #1435422: zlib's compress and decompress objects now have a
771 copy() method.
772
Andrew MacIntyre92913322006-06-13 15:04:24 +0000773- Patch #1454481: thread stack size is now tunable at runtime for thread
774 enabled builds on Windows and systems with Posix threads support.
775
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000776- On Win32, os.listdir now supports arbitrarily-long Unicode path names
777 (up to the system limit of 32K characters).
778
779- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
780 As a result, these functions now raise WindowsError instead of OSError.
781
Tim Peters7a822da2006-05-25 21:50:17 +0000782- ``time.clock()`` on Win64 should use the high-performance Windows
783 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
784 Windows platforms).
785
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000786- Calling Tk_Init twice is refused if the first call failed as that
787 may deadlock.
788
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000789- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
790 accept it without potentially using an uninitialized pointer.
791
792- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
793 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
794 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000795
Gregory P. Smith372b5832006-06-05 18:48:21 +0000796- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000797 [pybsddb project SF patch number 1466734]
798
Gregory P. Smith372b5832006-06-05 18:48:21 +0000799- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
800 parameter is supplied. [SF pybsddb bug #1477863]
801
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000802- bsddb: the __len__ method of a DB object has been fixed to return correct
803 results. It could previously incorrectly return 0 in some cases.
804 Fixes SF bug 1493322 (pybsddb bug 1184012).
805
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000806- bsddb: the bsddb.dbtables Modify method now raises the proper error and
807 aborts the db transaction safely when a modifier callback fails.
808 Fixes SF python patch/bug #1408584.
809
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000810- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000811 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000812 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
813 database calls that would previously deadlock. [SF python bug #775414]
814
Vinay Sajip28e57612006-07-01 10:45:20 +0000815- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000816
Walter Dörwald4994d952006-06-19 08:07:50 +0000817- Patch #1506645: add Python wrappers for the curses functions
818 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000819
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000820Library
821-------
822
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000823- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
824 functions.
825
Martin v. Löwis3798da02006-06-17 18:44:27 +0000826- Patch #812986: Update turtle output even if not tracing.
827
Vinay Sajip28e57612006-07-01 10:45:20 +0000828- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000829 Tkinter.BaseWidget.
830
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000831- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
832
Martin v. Löwis337487e2006-06-17 09:15:14 +0000833- Patch #763580: Add name and value arguments to Tkinter variable
834 classes.
835
Georg Brandl83cc0d02006-06-14 08:50:03 +0000836- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
837 mime.types file for determining MIME types.
838
Georg Brandl2605ca82006-06-14 06:08:31 +0000839- Bug #1339007: Shelf objects now don't raise an exception in their
840 __del__ method when initialization failed.
841
Martin v. Löwisd8251432006-06-14 05:21:04 +0000842- Patch #1455898: The MBCS codec now supports the incremental mode for
843 double-byte encodings.
844
Tim Peters43898b42006-06-14 04:09:25 +0000845- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
846 guarantee that adjacent triples in the return list always describe
847 non-adjacent blocks. Previously, a pair of matching blocks could end
848 up being described by multiple adjacent triples that formed a partition
849 of the matching pair.
850
Greg Ward0e0c9f42006-06-11 16:24:11 +0000851- Bug #1498146: fix optparse to handle Unicode strings in option help,
852 description, and epilog.
853
Greg Wardd1c797e2006-06-11 14:42:41 +0000854- Bug #1366250: minor optparse documentation error.
855
Greg Ward7f547402006-06-11 00:40:49 +0000856- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
857 clarify docs.
858
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000859- The wsgiref package has been added to the standard library.
860
Nick Coghlan676725d2006-06-08 13:54:49 +0000861- The functions update_wrapper() and wraps() have been added to the functools
862 module. These make it easier to copy relevant metadata from the original
863 function when writing wrapper functions.
864
Tim Petersd6a9eef2006-06-05 01:48:21 +0000865- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
866 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000867
Martin v. Löwis3f767792006-06-04 19:36:28 +0000868- Patch #1359618: Speed up charmap encoder by using a trie structure
869 for lookup.
870
Tim Petersd609b1a2006-06-02 23:22:51 +0000871- The functions in the ``pprint`` module now sort dictionaries by key
872 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
873 if and only if its display required more than one line, although that
874 wasn't documented. The new behavior increases predictability; e.g.,
875 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
876
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000877- Patch #1497027: try HTTP digest auth before basic auth in urllib2
878 (thanks for J. J. Lee).
879
Georg Brandl2b330372006-05-28 20:23:12 +0000880- Patch #1496206: improve urllib2 handling of passwords with respect to
881 default HTTP and HTTPS ports.
882
George Yoshidaf3c65de2006-05-28 16:39:09 +0000883- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
884
Bob Ippolito7298f272006-05-23 18:43:47 +0000885- Patch #1281707: speed up gzip.readline.
886
Georg Brandlb89316f2006-05-17 15:51:16 +0000887- Patch #1180296: Two new functions were added to the locale module:
888 format_string() to get the effect of "format % items" but locale-aware,
889 and currency() to format a monetary number with currency sign.
890
Georg Brandle3a25832006-05-17 14:56:04 +0000891- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
892 and several features added, such as speed and geometry control.
893
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000894- Patch #1488881: add support for external file objects in bz2 compressed
895 tarfiles.
896
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000897- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
898 stdout arguments, making it possible to redirect input and output
899 for remote debugging.
900
901- Patch #1484695: Update the tarfile module to version 0.8. This fixes
902 a couple of issues, notably handling of long file names using the
903 GNU LONGNAME extension.
904
905- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
906 new flag when ``name`` is already the name of an option flag.
907
908- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
909 package.
910
911- Patch #1472854: make the rlcompleter.Completer class usable on non-
912 UNIX platforms.
913
914- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000947What's New in Python 2.5 alpha 2?
948=================================
949
950*Release date: 27-APR-2006*
951
952Core and builtins
953-----------------
954
Thomas Heller1b046642006-04-18 18:51:06 +0000955- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
956 by converting these apis from macros into exported functions again:
957
958 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
959 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
960 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
961 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
962 PyRun_String Py_CompileString
963
Martin v. Löwis45294a92006-04-18 06:24:08 +0000964- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
965
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000966- All uses of PyStructSequence_InitType have been changed to initialize
967 the type objects only once, even if the interpreter is initialized
968 multiple times.
969
Neal Norwitz61546162006-04-14 05:20:28 +0000970- Bug #1454485, array.array('u') could crash the interpreter. This was
971 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
972 to unicode when it didn't make sense. 'u#' now requires a unicode string.
973
974- Py_UNICODE is unsigned. It was always documented as unsigned, but
975 due to a bug had a signed value in previous versions.
976
Tim Peters3a5e8b12006-04-11 01:44:07 +0000977- Patch #837242: ``id()`` of any Python object always gives a positive
978 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
979 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000980 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000981 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000982
Tim Peters3a5e8b12006-04-11 01:44:07 +0000983 def __hash__(self):
984 return id(self) # WRONG
985
986 because a hash result must be a (short) Python int but it was always
987 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000988 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000989 was always usable as a hash value before this patch. That's no longer
990 necessarily so.
991
992- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000993 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000994 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000995 #1454844)
996
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000997- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
998 involving generators that have paused outside of any ``try`` or ``with``
999 blocks. (In 2.5a1, a paused generator that was part of a reference
1000 cycle could not be garbage collected, regardless of whether it was
1001 paused in a ``try`` or ``with`` block.)

1005
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001006- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1007 is a macro.
1008
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001009- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1010 fails with an error condition.
1011
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001012- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1013
1014- Bug #1117761: bsddb.*open() no longer raises an exception when using
1015 the cachesize parameter.
1016
1017- Bug #1149413: bsddb.*open() no longer raises an exception when using
1018 a temporary db (file=None) with the 'n' flag to truncate on open.
1019
1020- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1021 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001022
Armin Rigoa9017c32006-04-19 11:50:27 +00001023- Patch #1062014: AF_UNIX sockets under Linux have a special
1024 abstract namespace that is now fully supported.
1025
Anthony Baxter51bcb682006-04-05 14:51:42 +00001026Library
1027-------
1028
Peter Astrand7d1d4362006-07-14 14:04:45 +00001029- Bug #1223937: subprocess.CalledProcessError reports the exit status
1030 of the process using the returncode attribute, instead of
1031 abusing errno.
1032
Tim Peters711bf302006-04-25 03:31:36 +00001033- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1034 a doctest to be skipped (the code is not run, and the expected output
1035 or exception is ignored).
1036
Nick Coghlanda2268f2006-04-24 04:37:15 +00001037- Fixed contextlib.nested to cope with exceptions being raised and
1038 caught inside exit handlers.
1039
Greg Wardab05edc2006-04-23 03:47:58 +00001040- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1041 hex, octal, or binary; add ``append_const`` action; keep going if
1042 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1043 added ``epilog`` for better help generation).
1044
Tim Peters21fbd572006-04-21 21:18:10 +00001045- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1046 called from a thread spawned as a side effect of importing a module.
1047
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001048- The pydoc module now supports documenting packages contained in
1049 .zip or .egg files.
1050
1051- The pkgutil module now has several new utility functions, such
1052 as ``walk_packages()`` to support working with packages that are either
1053 in the filesystem or zip files.
1054
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001055- The mailbox module can now modify and delete messages from
1056 mailboxes, in addition to simply reading them. Thanks to Gregory
1057 K. Johnson for writing the code, and to the 2005 Google Summer of
1058 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001059
Tim Petersc7605f22006-04-17 21:12:33 +00001060- The ``__del__`` method of class ``local`` in module ``_threading_local``
1061 returned before accomplishing any of its intended cleanup.
1062
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001063- Patch #790710: Add breakpoint command lists in pdb.
1064
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001065- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +00001067- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1068
Anthony Baxtere29002c2006-04-12 12:07:31 +00001069- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1070 Windows. Bug #1469163.
1071
Phillip J. Eby47032112006-04-11 01:07:43 +00001072- The warnings, linecache, inspect, traceback, site, and doctest modules
1073 were updated to work correctly with modules imported from zipfiles or
1074 via other PEP 302 __loader__ objects.
1075
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001076- Patch #1467770: Reduce usage of subprocess._active to processes which
1077 the application hasn't waited on.
1078
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001079- Patch #1462222: Fix Tix.Grid.
1080
Neal Norwitza31bf182006-04-09 03:35:43 +00001081- Fix exception when doing glob.glob('anything*/')
1082
Skip Montanaro262fb922006-04-21 02:31:07 +00001083- The pstats.Stats class accepts an optional stream keyword argument to
1084 direct output to an alternate file-like object.
1085
Anthony Baxter51bcb682006-04-05 14:51:42 +00001086Build
1087-----
1088
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001089- The Makefile now has a reindent target, which runs reindent.py on
1090 the library.
1091
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001092- Patch #1470875: Building Python with MS Free Compiler
1093
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001094- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001095
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001096- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1097 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001098 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001099 CXX from --with-cxx-main, see description in README.
1100
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001101- Patch #1429775: Link extension modules with the shared libpython.
1102
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001103- Fixed a libffi build problem on MIPS systems.
1104
Tim Peters8931ff12006-05-13 23:28:20 +00001105- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1106 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1107 and "%zu" for unsigned integers of type ``size_t``.
1108
Anthony Baxter51bcb682006-04-05 14:51:42 +00001109Tests
1110-----
1111
Nick Coghlanda2268f2006-04-24 04:37:15 +00001112- test_contextlib now checks contextlib.nested can cope with exceptions
1113 being raised and caught inside exit handlers.
1114
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001115- test_cmd_line now checks operation of the -m and -c command switches
1116
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001117- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1118 it separately and by hand. It also wasn't cleaning up its changes to
1119 the current Decimal context.
1120
Thomas Woutersabd08882006-04-26 15:53:30 +00001121- regrtest.py now has a -M option to run tests that test the new limits of
1122 containers, on 64-bit architectures. Running these tests is only sensible
1123 on 64-bit machines with more than two gigabytes of memory. The argument
1124 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001132Documentation
1133-------------
1134
Tim Petersb06d28c2006-05-12 01:57:59 +00001135- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1136
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001137- PEP 343: Added Context Types section to the library reference
1138 and attempted to bring other PEP 343 related documentation into
1139 line with the implementation and/or python-dev discussions.
1140
Tim Peters8dc73d22006-04-24 02:03:16 +00001141- Bug #1337990: clarified that ``doctest`` does not support examples
1142 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001145What's New in Python 2.5 alpha 1?
1146=================================
1147
Anthony Baxterebed3f62006-04-03 15:03:44 +00001148*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001149
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001150Core and builtins
1151-----------------
1152
Nick Coghlan43832302006-04-23 17:04:07 +00001153- PEP 338: -m command line switch now delegates to runpy.run_module
1154 allowing it to support modules in packages and zipfiles
1155
Martin v. Löwisc661b882006-04-20 04:54:23 +00001156- On Windows, .DLL is not an accepted file name extension for
1157 extension modules anymore; extensions are only found if they
1158 end in .PYD.
1159
Martin v. Löwisea62d252006-04-03 10:56:49 +00001160- Bug #1421664: sys.stderr.encoding is now set to the same value as
1161 sys.stdout.encoding.
1162
Neal Norwitz92e212f2006-04-03 04:48:37 +00001163- __import__ accepts keyword arguments.
1164
Georg Brandlccadf842006-03-31 18:54:53 +00001165- Patch #1460496: round() now accepts keyword arguments.
1166
Anthony Baxter262c00a2006-03-30 10:53:17 +00001167- Fixed bug #1459029 - unicode reprs were double-escaped.
1168
Hye-Shik Changd478f342006-03-23 12:32:36 +00001169- Patch #1396919: The system scope threads are reenabled on FreeBSD
1170 5.4 and later versions.
1171
Neal Norwitze98ccf62006-03-23 05:39:47 +00001172- Bug #1115379: Compiling a Unicode string with an encoding declaration
1173 now gives a SyntaxError.
1174
Georg Brandlabd1ff82006-03-18 07:59:59 +00001175- Previously, Python code had no easy way to access the contents of a
1176 cell object. Now, a ``cell_contents`` attribute has been added
1177 (closes patch #1170323).
1178
Tim Peterscf79aac2006-03-16 01:14:46 +00001179- Patch #1123430: Python's small-object allocator now returns an arena to
1180 the system ``free()`` when all memory within an arena becomes unused
1181 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1182 freed. Some applications will see a drop in virtual memory size now,
1183 especially long-running applications that, from time to time, temporarily
1184 use a large number of small objects. Note that when Python returns an
1185 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001186 platform C library will in turn return that memory to the operating system.
1187 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001188 appears to be effective at least on Microsoft C and gcc-based systems.
1189 Thanks to Evan Jones for hard work and patience.
1190
Georg Brandl533ff6f2006-03-08 18:09:27 +00001191- Patch #1434038: property() now uses the getter's docstring if there is
1192 no "doc" argument given. This makes it possible to legitimately use
1193 property() as a decorator to produce a read-only property.
1194
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001195- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1196 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1197 of requiring an int or long in slicing and a few other contexts, enabling
1198 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1199
Neal Norwitz995acdf2006-03-07 05:01:00 +00001200- Fixed various bugs reported by Coverity's Prevent tool.
1201
Brett Cannonbf364092006-03-01 04:25:17 +00001202- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1203 new exception base class, BaseException, which has a new message attribute.
1204 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1205 Raising a string exception now raises a DeprecationWarning.
1206
Thomas Woutersfb609f42006-02-28 16:37:25 +00001207- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1208 explicitly relative, using 'from .module import name' to mean 'from the same
1209 package as this module is in. Imports without dots still default to the
1210 old relative-then-absolute, unless 'from __future__ import
1211 absolute_import' is used.
1212
Brett Cannona7446e32006-02-27 23:39:10 +00001213- Properly check if 'warnings' raises an exception (usually when a filter set
1214 to "error" is triggered) when raising a warning for raising string
1215 exceptions.
1216
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001217- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001218 The name was removed from Include/code.h.
1219
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001220- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001221
Guido van Rossum1968ad32006-02-25 22:38:04 +00001222- Patch 1433928:
1223 - The copy module now "copies" function objects (as atomic objects).
1224 - dict.__getitem__ now looks for a __missing__ hook before raising
1225 KeyError.
1226
Tim Peters84ef21c2006-02-28 20:39:06 +00001227- PEP 343: with statement implemented. Needs ``from __future__ import
1228 with_statement``. Use of 'with' as a variable will generate a warning.
1229 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001230 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001231 The following objects have __context__ methods:
1232 - The built-in file type.
1233 - The thread.LockType type.
1234 - The following types defined by the threading module:
1235 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1236 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001237
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001238- Fix the encodings package codec search function to only search
1239 inside its own package. Fixes problem reported in patch #1433198.
1240
1241 Note: Codec packages should implement and register their own
1242 codec search function. PEP 100 has the details.
1243
Tim Peters9ea89d22006-06-04 03:26:02 +00001244- PEP 353: Using ``Py_ssize_t`` as the index type.
1245
1246- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1247 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1248 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1249 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1250 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001251
Neal Norwitzfc76d632006-01-10 06:03:13 +00001252- Patch #1400181, fix unicode string formatting to not use the locale.
1253 This is how string objects work. u'%f' could use , instead of .
1254 for the decimal point. Now both strings and unicode always use periods.
1255
Neal Norwitz671b9e32006-01-09 07:07:12 +00001256- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1257 configure would break checking curses.h.
1258
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001259- Bug #959576: The pwd module is now builtin. This allows Python to be
1260 built on UNIX platforms without $HOME set.
1261
Neal Norwitzc10978f2005-12-19 06:07:16 +00001262- Bug #1072182, fix some potential problems if characters are signed.
1263
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001264- Bug #889500, fix line number on SyntaxWarning for global declarations.
1265
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001266- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1267
Neal Norwitze7214a12005-12-18 05:03:17 +00001268- Support for converting hex strings to floats no longer works.
1269 This was not portable. float('0x3') now raises a ValueError.
1270
Barry Warsaw2a38a862005-12-18 01:27:35 +00001271- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001272 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001273 is now displayed in interactive prompt banner.
1274
Georg Brandlfa166682005-12-17 21:45:17 +00001275- Implementation of PEP 341 - Unification of try/except and try/finally.
1276 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001277 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001278
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001279- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1280 now encodes backslash correctly.
1281
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001282- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1283
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001284- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001285 and long longs.
1286
Neal Norwitz67715f02005-11-09 06:59:35 +00001287- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001288 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001289 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001290
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001291- Replaced most Unicode charmap codecs with new ones using the
1292 new Unicode translate string feature in the builtin charmap
1293 codec; the codecs were created from the mapping tables available
1294 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1295 encodings now include a mapping for the Apple logo)
1296
Tim Peterse3547fd2005-12-16 23:13:57 +00001297- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001298
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001299- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001300
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001301- A new AST parser implementation was completed. The abstract
1302 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001303 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001304
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001305- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001306 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1307
Neal Norwitz708e51a2005-10-03 04:48:15 +00001308- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1309
Neal Norwitz11bd1192005-10-03 00:54:56 +00001310- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1311 Provide a warning when a directory is passed on the command line.
1312
Neal Norwitz40d37812005-10-02 01:48:49 +00001313- Fix segfault with invalid coding.
1314
1315- SF bug #772896: unknown encoding results in MemoryError.
1316
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001317- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001318 supported a __len__() method which evaluated to False when the iterator
1319 was empty.
1320
Guido van Rossum630db602005-09-20 18:49:54 +00001321- On 64-bit platforms, when __len__() returns a value that cannot be
1322 represented as a C int, raise OverflowError.
1323
Skip Montanarof8948ca2005-09-19 03:54:46 +00001324- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001325 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001326
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001327- SF bug #893549: parsing keyword arguments was broken with a few format
1328 codes.
1329
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001330- Changes donated by Elemental Security to make it work on AIX 5.3
1331 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1332 bug #105470: test_pwd fails on 64bit system (Opteron).
1333
Guido van Rossum539c6622005-09-14 17:49:54 +00001334- Changes donated by Elemental Security to make it work on HP-UX 11 on
1335 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1336
Georg Brandl4550b8d2005-08-26 06:43:52 +00001337- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001338 (fixes bug #1119418).
1339
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001340- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1341
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001342- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1343 exceptions that cause a function to exit.
1344
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001345- The implementation of set() and frozenset() was revised to use its
1346 own internal data structure. Memory consumption is reduced by 1/3
1347 and there are modest speed-ups as well. The API is unchanged.
1348
Tim Petersde7990b2005-07-17 23:45:23 +00001349- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1350
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001351- SF bug #1229429: PyObject_CallMethod failed to decrement some
1352 reference counts in some error exit cases.
1353
Tim Petersecc6e6a2005-07-10 22:30:55 +00001354- SF bug #1185883: Python's small-object memory allocator took over
1355 a block managed by the platform C library whenever a realloc specified
1356 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001357 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001358 portable way to copy data from the C-managed block into Python's
1359 small-object space without risking a memory fault. Python's small-object
1360 realloc now leaves such blocks under the control of the platform C
1361 realloc.
1362
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001363- SF bug #1232517: An overflow error was not detected properly when
1364 attempting to convert a large float to an int in os.utime().
1365
Raymond Hettinger3296e692005-06-29 23:29:56 +00001366- SF bug #1224347: hex longs now print with lowercase letters just
1367 like their int counterparts.
1368
Michael W. Hudson188d4362005-06-20 16:52:57 +00001369- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1370 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1371 interpreter states; back out that fix and do a better job (see
1372 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1373 for a longer write-up of the problem).
1374
Michael W. Hudsondf888462005-06-03 14:41:55 +00001375- SF patch #1180995: marshal now uses a binary format by default when
1376 serializing floats.
1377
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001378- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1379 the routines that promise to produce IEEE 754 binary representations
1380 of floats now simply copy bytes around.
1381
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001382- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1383 278.
1384
Brett Cannonc3647ac2005-04-26 03:45:26 +00001385- patch #1109424: int, long, float, complex, and unicode now check for the
1386 proper magic slot for type conversions when subclassed. Previously the
1387 magic slot was ignored during conversion. Semantics now match the way
1388 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001389 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001390 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001391 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001392
Barry Warsawc8d907c2005-04-19 23:43:40 +00001393- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1394 NULL, now raise an AttributeError when attempting to set or delete the
1395 attribute. Previously a TypeError was raised, but this was inconsistent
1396 with the equivalent pure-Python implementation.
1397
Michael W. Hudson774479c2005-04-18 08:46:17 +00001398- It is now safe to call PyGILState_Release() before
1399 PyEval_InitThreads() (note that if there is reason to believe there
1400 are multiple threads around you still must call PyEval_InitThreads()
1401 before using the Python API; this fix is for extension modules that
1402 have no way of knowing if Python is multi-threaded yet).
1403
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001404- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1405 disabled caused a crash.
1406
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001407- Bug #1165306: instancemethod_new allowed the creation of a method
1408 with im_class == im_self == NULL, which caused a crash when called.
1409
Tim Petersecc6e6a2005-07-10 22:30:55 +00001410- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001411 fixes the crash seen in bug #1165761
1412
Raymond Hettinger96229b12005-03-11 06:49:40 +00001413- Added two new builtins, any() and all().
1414
Brett Cannon409d8f22005-03-05 06:47:57 +00001415- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001416 (e.g., ``class C(): pass`` is no longer a syntax error).
1417 Patch #1176012 added support to the 'parser' module and 'compiler' package
1418 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001419
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001420- Patch #1115086: Support PY_LONGLONG in structmember.
1421
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001422- Bug #1155938: new style classes did not check that __init__() was
1423 returning None.
1424
Tim Petersecc6e6a2005-07-10 22:30:55 +00001425- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001426 ('\') with a specific error message.
1427
Martin v. Löwisff232d72005-03-03 09:24:38 +00001428- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1429
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001430- Bug #1124295: the __name__ attribute of file objects was
1431 inadvertently made inaccessible in restricted mode.
1432
Tim Petersecc6e6a2005-07-10 22:30:55 +00001433- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001434 an ferror() call.
1435
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001436- min() and max() now support key= arguments with the same meaning as in
1437 list.sort().
1438
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001439- The peephole optimizer now performs simple constant folding in expressions:
1440 (2+3) --> (5).
1441
Raymond Hettingera422c342005-01-11 03:03:27 +00001442- set and frozenset objects can now be marshalled. SF #1098985.
1443
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001444- Bug #1077106: Poor argument checking could cause memory corruption
1445 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001446
Jeremy Hyltonab630502005-02-04 18:44:06 +00001447- The parser did not complain about future statements in illegal
1448 positions. It once again reports a syntax error if a future
1449 statement occurs after anything other than a doc string.
1450
Neil Schemenauercf52c072005-08-12 17:34:58 +00001451- Change the %s format specifier for str objects so that it returns a
1452 unicode instance if the argument is not an instance of basestring and
1453 calling __str__ on the argument returns a unicode instance.
1454
Tim Petersf4e69282006-02-27 17:15:31 +00001455- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1456 current thread state when the auto-GIL-state machinery knows about
1457 it (since the thread state is being deleted, continuing to remember it
1458 can't help, but can hurt if another thread happens to get created with
1459 the same thread id).
1460
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001461Extension Modules
1462-----------------
1463
Georg Brandl43f08a82006-03-31 18:01:16 +00001464- Patch #1380952: fix SSL objects timing out on consecutive read()s
1465
Neal Norwitz05a45592006-03-20 06:30:08 +00001466- Patch #1309579: wait3 and wait4 were added to the posix module.
1467
Anthony Baxterfa869072006-03-20 05:21:58 +00001468- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1469 In addition, the existing ulaw code was updated.
1470
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001471- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001472 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001473
Neal Norwitz10be10c2006-03-16 06:50:13 +00001474- Everything under lib-old was removed. This includes the following modules:
1475 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001476 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001477 util, whatsound, whrandom, zmod
1478
1479- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1480
1481- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001482 is deprecated. The undocumented re.engine variable no longer exists.

1592 the request code argument, which results in more C-like behaviour
1593 for large or negative values.
1594
Tim Petersecc6e6a2005-07-10 22:30:55 +00001595- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001635- the cPickle module no longer accepts the deprecated None option in the
1636 args tuple returned by __reduce__().
1637
Raymond Hettingerb2594052004-12-05 09:25:51 +00001638- itertools.islice() now accepts None for the start and step arguments.
1639 This allows islice() to work more readily with slices:
1640 islice(s.start, s.stop, s.step)
1641
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001642- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001651- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1652 been renamed to have only a single underscore prefix. This was done to
1653 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001654
Nick Coghlan43832302006-04-23 17:04:07 +00001655- PEP 338: new module runpy defines a run_module function to support
1656 executing modules which provide access to source code or a code object
1657 via the PEP 302 import mechanisms.
1658
Anthony Baxter93f5b932006-04-03 08:05:07 +00001659- The email module's parsedate_tz function now sets the daylight savings

1667 in attribute values.
1668
Anthony Baxterc51ee692006-04-01 00:57:31 +00001669- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001670 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001671 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001672 module will not be built.
1673
Tim Petersc17976e2006-04-01 00:26:53 +00001674- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1675 aren't officially supported here, and trying to use them will probably
1676 raise an exception some day. But dicts have been allowed, and "mostly
1677 worked", so support for them won't go away without warning.
1678
Georg Brandl338ef7d2006-03-31 18:42:16 +00001679- Bug #1445068: getpass.getpass() can now be given an explicit stream
1680 argument to specify where to write the prompt.
1681

1697
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001698- email 4.0 package now integrated. This is largely the same as the email 3.0
1699 package that was included in Python 2.3, except that PEP 8 module names are
1700 now used (e.g. mail.message instead of email.Message). The MIME classes
1701 have been moved to a subpackage (e.g. email.mime.text instead of
1702 email.MIMEText). The old names are still supported for now. Several
1703 deprecated Message methods have been removed and lots of bugs have been
1704 fixed. More details can be found in the email package documentation.
1705
Walter Dörwald40108c92006-03-27 08:15:44 +00001706- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1707 (a subclass of tuple) that provides incremental decoders and encoders
1708 (a way to use stateful codecs without the stream API). Python functions
1709 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1710 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1711 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001713- Patch #1359365: Calling next() on a closed StringIO.String object raises
1714 a ValueError instead of a StopIteration now (like file and cString.String do).
1715 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1716 called before (like file and StringIO.StringIO do).

1786 LoadError as documented, instead of IOError. For compatibility,
1787 LoadError subclasses IOError.
1788
Brett Cannon3cbd0382005-12-16 22:49:23 +00001789- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001790 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1791 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1792 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1793 Ronald L. Rivest offered this advice for Python:
1794
1795 "The consensus of researchers in this area (at least as
1796 expressed at the NIST Hash Function Workshop 10/31/05),
1797 is that SHA-256 is a good choice for the time being, but
1798 that research should continue, and other alternatives may
1799 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001800
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001801- Added a subset of Fredrik Lundh's ElementTree package. Available

1920 work as expected.
1921
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001922- Bug #1163325: Decimal infinities failed to hash. Attempting to

Guido van Rossumd0641422005-02-03 15:01:24 +00001960- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1961 disables recursive traversal through instance attributes, which can
1962 be exploited in various ways.
1963
Tim Peterse3547fd2005-12-16 23:13:57 +00001964- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec

1978
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001979- Enhancements to the csv module:
1980
1981 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001982 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001983 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001984 + Dialect parameter parsing has been re-implemented to improve error
1985 reporting.
1986 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1987 dictates.
1988 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001989 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001990 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001991 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1992 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001993 + reader now allows \r characters to be quoted (previously it only allowed
1994 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001995 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001996 + Dialect classes passed to the module are no longer instantiated by
1997 the module before being parsed (the former validation scheme required
1998 this, but the mechanism was unreliable).
1999 + The dialect registry now contains instances of the internal
2000 C-coded dialect type, rather than references to python objects.
2001 + the internal c-coded dialect type is now immutable.
2002 + register_dialect now accepts the same keyword dialect specifications
2003 as the reader and writer, allowing the user to register dialects
2004 without first creating a dialect class.
2005 + a configurable limit to the size of parsed fields has been added -
2006 previously, an unmatched quote character could result in the entire
2007 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002008 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002009 the parser field size limit (returning the former limit). The initial
2010 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002011 + A line_num attribute has been added to the reader object, which tracks
2012 the number of lines read from the source iterator. This is not
2013 the same as the number of records returned, as records can span
2014 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002015 + reader and writer objects were not being registered with the cyclic-GC.
2016 This has been fixed.
2017
Brett Cannone6539c42005-01-08 02:43:53 +00002018- _DummyThread objects in the threading module now delete self.__block that is
2019 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2020 lock primitives tend to be limited in number and thus should not be wasted on
2021 a _DummyThread object. Fixes bug #1089632.
2022
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002023- The imghdr module now detects Exif files.
2024
Raymond Hettinger6065d322004-12-20 23:51:53 +00002025- StringIO.truncate() now correctly adjusts the size attribute.
2026 (Bug #951915).
2027
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002028- locale.py now uses an updated locale alias table (built using
2029 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2030 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002031 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002032
Raymond Hettinger3557f422004-12-07 12:02:02 +00002033- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2034
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002035- the pickle module no longer accepts the deprecated None option in the
2036 args tuple returned by __reduce__().
2037
Brett Cannon84667c02004-12-07 03:25:18 +00002038- optparse now optionally imports gettext. This allows its use in setup.py.
2039
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002040- the pickle module no longer uses the deprecated bin parameter.
2041
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002042- the shelve module no longer uses the deprecated binary parameter.
2043

2045
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002046- the filecmp module no longer uses the deprecated use_statcache argument.
2047
Raymond Hettinger664347b2004-12-04 21:21:53 +00002048- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2049 extended or overridden by subclasses. Formerly, the subclassed method would
2050 be ignored by the rest of the module. (Bug #1078905).
2051
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002052- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002053 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002054
Walter Dörwald36733692004-12-22 12:50:50 +00002055- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2056 once when a size argument is given. This prevents a buffer overflow in the
2057 tokenizer with very long source lines.
2058
Barry Warsaw538561e2006-01-01 21:48:54 +00002059- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2060 immediately after creating the object, without any intervening
2061 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002062
Skip Montanaro05885812005-01-16 20:48:27 +00002063- The reconvert.quote function can now emit triple-quoted strings. The
2064 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002065
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002066- ``UserString.MutableString`` now supports negative indices in
2067 ``__setitem__`` and ``__delitem__``
2068
Greg Ward40407942005-03-05 02:53:17 +00002069- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2070 correctly.
2071
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002072- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2073 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2074 character even if the user has passed a size parameter to get a proper
2075 line ending. Remove the special handling of a "\r\n" that has been split
2076 between two lines.
2077
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002078- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2079 about illegal code points. The codec now supports PEP 293 style error
2080 handlers.
2081
Walter Dörwald78a78b02005-09-01 12:04:29 +00002082- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002083 from the input stream, so that the output is a byte string in the correct
2084 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002085
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002086- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2087 considering it exactly like a '*'.
2088
Walter Dörwald007f8df2005-10-09 19:42:27 +00002089- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2090 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002091
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002092- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2093
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002094- Patch #1413711: Certain patterns of differences were making difflib
2095 touch the recursion limit.
2096
Walter Dörwald58917a62006-03-31 15:26:22 +00002097- Bug #947906: An object oriented interface has been added to the calendar
2098 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002099 called as a script (e.g. via ``python -mcalendar``). Localized month and
2100 weekday names can be ouput (even if an exotic encoding is used) using
2101 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002102

2104-----
2105
Neal Norwitz602d3392006-03-31 08:21:40 +00002106- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2107 by using -mieee gcc option.
2108
Martin v. Löwis86d66262006-02-17 08:40:11 +00002109- Patch #1432345: Make python compile on DragonFly.
2110
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002111- Build support for Win64-AMD64 was added.
2112
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002113- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2114
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002115- Patch #881820: look for openpty and forkpty also in libbsd.
2116
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002117- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2118 The zlib module is now builtin on Windows.
2119
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002120- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2121
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002122- Bug #1189330: configure did not correctly determine the necessary
2123 value of LINKCC if python was built with GCC 4.0.
2124
Trent Mick8321b422005-07-26 02:29:21 +00002125- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2126 vulnerability in zlib 1.2.1 and 1.2.2.
2127
Brett Cannon08cd5982005-04-24 22:26:38 +00002128- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2129 flags that change binary compatibility. Changes were also made to
2130 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002131 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002132
Bob Ippolitoed233462005-03-29 13:47:59 +00002133- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2134 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2135 no longer exists). This configure patch makes things right.
2136
Martin v. Löwise2713be2005-03-08 15:03:08 +00002137- Bug #1158607: Build with --disable-unicode again.
2138
Brett Cannon46d96232005-02-16 00:07:19 +00002139- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2140 defined. Discovered as a result of not being able to build on OS X.
2141
Brett Cannon516592f2004-12-07 00:42:59 +00002142- setup.py now uses the directories specified in LDFLAGS using the -L option
2143 and in CPPFLAGS using the -I option for adding library and include
2144 directories, respectively, for compiling extension modules against. This has
2145 led to the core being compiled using the values in CPPFLAGS. It also removes
2146 the need for the special-casing of both DarwinPorts and Fink for darwin since
2147 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2148 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2149 Fink, ``-I/opt/local/include`` for DarwinPorts).
2150
Brett Cannon43802422005-02-10 20:48:03 +00002151- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2152 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2153 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2154 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002156C API
2157-----
2158
Tim Petersc9d78aa2006-03-26 23:27:58 +00002159- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2160 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2161 is obtained via the ``PyObject_`` family, it must be released via the
2162 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2163 always been officially true, but when Python's small-object allocator was
2164 introduced, an attempt was made to cater to a few extension modules
2165 discovered at the time that obtained memory via ``PyObject_New`` but
2166 released it via ``PyMem_DEL``. It's years later, and if such code still
2167 exists it will fail now (probably with segfaults, but calling wrong
2168 low-level memory management functions can yield many symptoms).
2169
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002170- Added a C API for set and frozenset objects.
2171
Raymond Hettinger66517482004-12-03 11:45:13 +00002172- Removed PyRange_New().
2173
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002174- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2175 mapping argument now. This string is used as a mapping table. Byte values
2176 greater than the length of the string and 0xFFFE are treated as undefined
2177 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002184
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002185- Patch #1276356: New resource "urlfetch" is implemented. This enables
