82-----------------
83
Neal Norwitz0bcafac2006-09-11 08:51:17 +000084- Make _PyGILState_NoteThreadState() static, it was not used anywhere
85 outside of pystate.c and should not be necessary.
86
Brett Cannon19d76c52006-09-09 07:18:44 +000087- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
88 allows calling unicode() on exceptions classes directly to succeed.
89
Georg Brandlecab6232006-09-06 06:47:02 +000090- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl37a9e572006-09-06 06:09:34 +000094- Bug #1550983: emit better error messages for erroneous relative
95 imports (if not in package and if beyond toplevel package).
96
Tim Peterscbdd3502006-09-05 01:47:53 +000097- Overflow checking code in integer division ran afoul of new gcc
98 optimizations. Changed to be more standard-conforming.

104
Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000105- The return tuple from str.rpartition(sep) is (tail, sep, head) where
106 head is the original string if sep was not found.
107
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000108- Bug #1520864: unpacking singleton tuples in list comprehensions and
109 generator expressions (x for x, in ... ) works again. Fixing this problem
110 required changing the .pyc magic number. This means that .pyc files
111 generated before 2.5c2 will be regenerated.

202Core and builtins
203-----------------
204
Neal Norwitz24b6f202006-09-05 04:43:56 +0000205- Fix infinite recursion when subclassing long and overriding __hash__.
206
207- Fix concatenation (+=) of long strings.
208
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000209- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000210 compared equal or unequal to a string and a UnicodeDecodeError
211 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000212
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000213 Instead, the equal (==) and unequal (!=) comparison operators will
214 now issue a UnicodeWarning and interpret the two objects as
215 unequal. The UnicodeWarning can be filtered as desired using
216 the warning framework, e.g. silenced completely, turned into an
217 exception, logged, etc.
218
219 Note that compare operators other than equal and unequal will still
220 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000221
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000222- Fix segfault when doing string formatting on subclasses of long.
223
224- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
225 with new-style classes.
226
227- Fix bug related to __len__ functions returning negative values with
228 classic classes.
229
230- Patch #1538606, Fix __index__() clipping. There were some problems
231 discovered with the API and how integers that didn't fit into Py_ssize_t
232 were handled. This patch attempts to provide enough alternatives
233 to effectively use __index__.
234
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000235- Bug #1536021: __hash__ may now return long int; the final hash
236 value is obtained by invoking hash on the long int.
237
Thomas Hellerab1049c2006-08-08 17:37:00 +0000238- Bug #1536786: buffer comparison could emit a RuntimeWarning.
239
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000240- Bug #1535165: fixed a segfault in input() and raw_input() when
241 sys.stdin is closed.
242
Thomas Heller74d36f02006-08-04 18:17:40 +0000243- On Windows, the PyErr_Warn function is now exported from
244 the Python dll again.
245
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000246- Bug #1191458: tracing over for loops now produces a line event
247 on each iteration. Fixing this problem required changing the .pyc
248 magic number. This means that .pyc files generated before 2.5c1
249 will be regenerated.
250
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000251- Bug #1333982: string/number constants were inappropriately stored
252 in the byte code and co_consts even if they were not used, ie
253 immediately popped off the stack.
254
Georg Brandle9462c72006-08-04 18:03:37 +0000255- Fixed a reference-counting problem in property().
256
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000257
258Library
259-------
260
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000261- Fix a bug in the ``compiler`` package that caused invalid code to be
262 generated for generator expressions.
263
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000264- The distutils version has been changed to 2.5.0. The change to
265 keep it programmatically in sync with the Python version running
266 the code (introduced in 2.5b3) has been reverted. It will continue
267 to be maintained manually as static string literal.
268
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000269- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000270 and this cannot be converted to the required C type, an exception is
271 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000272 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000273
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000274- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000275 an exception.
276
Tim Peterscbdd3502006-09-05 01:47:53 +0000277- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000278 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000279 workarounds for clocks with low resolution, to stop the code yielding
280 duplicate UUIDs.
281
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000282- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
283 before raising SystemExit, allowing IDLE to honor quit() and exit().
284
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000285- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
286
Georg Brandl7a1af772006-08-14 21:55:28 +0000287- Patch #1536071: trace.py should now find the full module name of a
288 file correctly even on Windows.
289
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000290- logging's atexit hook now runs even if the rest of the module has
291 already been cleaned up.
292
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000293- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000294
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000295- Bug #1531405, format_exception no longer raises an exception if
296 str(exception) raised an exception.
297
Neil Schemenauer06ded092006-08-04 16:20:30 +0000298- Fix a bug in the ``compiler`` package that caused invalid code to be
299 generated for nested functions.

310 raises the correct exceptions.
311
Thomas Heller1ce433e2006-08-14 16:20:04 +0000312- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
313 '-no-stack-protector' compiler flag for OpenBSD has been removed.
314
Thomas Heller86720042006-08-14 11:17:48 +0000315- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
316 uses the _as_parameter_ attribute when objects are passed to foreign
317 function calls. The ctypes version number was changed to 1.0.1.
318
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000319- Bug #1530559, struct.pack raises TypeError where it used to convert.
320 Passing float arguments to struct.pack when integers are expected

Fred Drake53912162006-07-29 13:22:49 +0000366What's New in Python 2.5 beta 3?
367================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000368
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000369*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000370
371Core and builtins
372-----------------
373
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000374- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000375 returned a long (see PEP 353).
376
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000377- Bug #1515471: string.replace() accepts character buffers again.
378
Neal Norwitz07aadb12006-07-30 06:55:48 +0000379- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
380 This provides the proper warning for struct.pack().
381 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
382
Neal Norwitz0d62a062006-07-30 06:53:31 +0000383- Patch #1531113: Fix augmented assignment with yield expressions.
384 Also fix a SystemError when trying to assign to yield expressions.
385
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000386- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
387 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
388 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
389 excessive filesystem operations during imports.
390
Tim Petersbc24eee2006-07-27 01:14:53 +0000391- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
392 operations on signed longs that are formally undefined by C.
393 Unfortunately, at least one compiler now cares about that, so complicated
394 the code to make that compiler happy again.
395
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000396- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
397
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000398- Patch #1232023: Stop including current directory in search
399 path on Windows.
400
Neal Norwitze1fdb322006-07-21 05:32:28 +0000401- Fix some potential crashes found with failmalloc.
402
Neal Norwitze7563102006-07-17 01:00:16 +0000403- Fix warnings reported by Klocwork's static analysis tool.
404
Neal Norwitz84be93b2006-07-16 01:50:38 +0000405- Bug #1512814, Fix incorrect lineno's when code within a function
406 had more than 255 blank lines.
407
Georg Brandl9dceedb2006-07-12 15:31:17 +0000408- Patch #1521179: Python now accepts the standard options ``--help`` and
409 ``--version`` as well as ``/?`` on Windows.
410
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000411- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000412 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000413 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000414
Tim Peters112aad32006-07-19 00:03:19 +0000415- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000416 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000417 new ``sys._current_frames()`` returns a dictionary with one entry,
418 mapping the faux "thread id" 0 to the current frame.
419
Ronald Oussoren3075e162006-07-25 20:28:55 +0000420- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000421
Ronald Oussoren3075e162006-07-25 20:28:55 +0000422
Neal Norwitza1f10902006-07-12 07:28:29 +0000423Library
424-------
425
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000426- Correction of patch #1455898: In the mbcs decoder, set final=False
427 for stream decoder, but final=True for the decode function.
428
Georg Brandl07fec3a2006-08-01 18:49:24 +0000429- os.urandom no longer masks unrelated exceptions like SystemExit or
430 KeyboardInterrupt.
431
Tim Peters4643c2f2006-08-10 22:45:34 +0000432- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000433 shutil.copytree on Windows
434
Georg Brandle34ac7c2006-07-30 11:07:23 +0000435- Bug #1002398: The documentation for os.path.sameopenfile now correctly
436 refers to file descriptors, not file objects.
437
Tim Peterscbdd3502006-09-05 01:47:53 +0000438- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000439 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000440 #1513611, and probably others.
441
Georg Brandledd9b0d2006-07-29 09:33:26 +0000442- Bug #1441397: The compiler module now recognizes module and function
443 docstrings correctly as it did in Python 2.4.
444
Tim Peters6f681472006-07-27 23:44:37 +0000445- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
446 lost that tests are sorted by name before being run. This rarely
447 matters for well-written tests, but can create baffling symptoms if
448 side effects from one test to the next affect outcomes. ``DocTestFinder``
449 has been changed to sort the list of tests it returns.
450
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000451- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000452 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000453
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000454- Bug #978833: Really close underlying socket in _socketobject.close.
455
Georg Brandldb232dc2006-08-20 13:15:43 +0000456- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
457 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000458
Georg Brandlcf0c1722006-07-26 07:23:32 +0000459- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
460 to recursive calls and call it with the failing package name.
461
Martin v. Löwis0b483032006-07-25 09:53:12 +0000462- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
463
Georg Brandlc13c34c2006-07-24 14:09:56 +0000464- Patch #1515343: Fix printing of deprecated string exceptions with a
465 value in the traceback module.
466
Greg Ward48fae7a2006-07-23 16:05:51 +0000467- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
468
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000469- Patch #1524429: Use repr() instead of backticks in Tkinter again.
470
Brett Cannoncaebe222006-07-18 04:41:36 +0000471- Bug #1520914: Change time.strftime() to accept a zero for any position in its
472 argument tuple. For arguments where zero is illegal, the value is forced to
473 the minimum value that is correct. This is to support an undocumented but
474 common way people used to fill in inconsequential information in the time
475 tuple pre-2.4.
476
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000477- Patch #1220874: Update the binhex module for Mach-O.
478
Barry Warsawb110bad2006-07-21 14:51:07 +0000479- The email package has improved RFC 2231 support, specifically for
480 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
481 (name*0=<blah>) parameter continuations. This may change the types of
482 values returned from email.message.Message.get_param() and friends.
483 Specifically in some cases where non-encoded continuations were used,
484 get_param() used to return a 3-tuple of (None, None, string) whereas now it
485 will just return the string (since non-encoded continuations don't have
486 charset and language parts).
487
488 Also, whereas % values were decoded in all parameter continuations, they are
489 now only decoded in encoded parameter parts.
490
Ronald Oussoren3075e162006-07-25 20:28:55 +0000491- Bug #1517990: IDLE keybindings on MacOS X now work correctly
492
493- Bug #1517996: IDLE now longer shows the default Tk menu when a
494 path browser, class browser or debugger is the frontmost window on MacOS X
495
Barry Warsaw00decd72006-07-27 23:43:15 +0000496- Patch #1520294: Support for getset and member descriptors in types.py,
497 inspect.py, and pydoc.py. Specifically, this allows for querying the type
498 of an object against these built-in types and more importantly, for getting
499 their docstrings printed in the interactive interpreter's help() function.

503-----------------
504
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000505- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
506 a socket operation on a socket with a timeout, the exception will be
507 caught correctly. Previously, the exception was not caught.
508
Thomas Heller1393d6a2006-07-28 21:43:20 +0000509- Patch #1529514: The _ctypes extension is now compiled on more
510 openbsd target platforms.
511
Tim Peters9cab5932006-07-28 00:30:00 +0000512- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
513 a memory leak, affecting pickles and deep copies.
514
Tim Petersbc24eee2006-07-27 01:14:53 +0000515- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000516 Paul Eggert.
517
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000518- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
519
Thomas Hellerce049a02006-07-14 17:51:14 +0000520- Patch #1521817: Index range checking on ctypes arrays containing
521 exactly one element enabled again. This allows iterating over these
522 arrays, without the need to check the array size before.
523
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000524- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000525 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000526 /dev/null in certain cases; this is now fixed.
527
Thomas Heller47d7a062006-07-12 08:43:47 +0000528- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
529 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000530
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000531- Because of a misspelled preprocessor symbol, ctypes was always
532 compiled without thread support; this is now fixed.
533
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000534- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
535 methods now allow their database parameter to be None as the
536 sleepycat API allows.
537
Matt Flemingec926502006-07-28 11:27:27 +0000538- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
539 bluetooth API compared with Linux and FreeBSD.
540
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000541Tests
542-----
543
544- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
545 how long the test file should take to play. Now accepts taking 2.93 secs
546 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
547
Georg Brandl4793aa32006-07-28 18:31:39 +0000548- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
549 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
550 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000557Mac
558---
559
560- PythonLauncher now works correctly when the path to the script contains
561 characters that are treated specially by the shell (such as quotes).
562
563- Bug #1527397: PythonLauncher now launches scripts with the working directory
564 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000565 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000566 expect.

575-----------------
576
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000577- Bug #1441486: The literal representation of -(sys.maxint - 1)
578 again evaluates to a int object, not a long.
579
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000580- Bug #1501934: The scope of global variables that are locally assigned
581 using augmented assignment is now correctly determined.
582
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000583- Bug #927248: Recursive method-wrapper objects can now safely
584 be released.
585
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000586- Bug #1417699: Reject locale-specific decimal point in float()
587 and atof().
588
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000589- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
590 omit a default "error" argument for NULL pointer. This allows
591 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000592
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000593- Bug #1519018: 'as' is now validated properly in import statements.
594
Neal Norwitz28746ab2006-07-09 22:14:42 +0000595- On 64 bit systems, int literals that use less than 64 bits are
596 now ints rather than longs.
597
Neal Norwitzed657552006-07-10 00:04:44 +0000598- Bug #1512814, Fix incorrect lineno's when code at module scope
599 started after line 256.
600
Tim Peters32a83612006-07-10 21:08:24 +0000601- New function ``sys._current_frames()`` returns a dict mapping thread
602 id to topmost thread stack frame. This is for expert use, and is
603 especially useful for debugging application deadlocks. The functionality
604 was previously available in Fazal Majid's ``threadframe`` extension
605 module, but it wasn't possible to do this in a wholly threadsafe way from
606 an extension.

623
Thomas Woutersadd19112006-07-05 11:03:49 +0000624- string.Template() now correctly handles tuple-values. Previously,
625 multi-value tuples would raise an exception and single-value tuples would
626 be treated as the value they contain, instead.
627
Martin v. Löwisede77f52006-07-03 13:01:35 +0000628- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
629 even if some data are received.
630

641 is created.
642
Martin v. Löwis7596e832006-07-01 15:33:37 +0000643- Bug #1513223: .close() of a _socketobj now releases the underlying
644 socket again, which then gets closed as it becomes unreferenced.
645
Fred Drake10497c82006-06-29 02:57:48 +0000646- Bug #1504333: Make sgmllib support angle brackets in quoted
647 attribute values.
648
649- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
650 sgmllib ('[' and ']' were not accepted).
651

653
Brett Cannon53ab5b72006-06-22 16:49:14 +0000654- Bug #1510580: The 'warnings' module improperly required that a Warning
655 category be either a types.ClassType and a subclass of Warning. The proper
656 check is just that it is a subclass with Warning as the documentation states.
657
Georg Brandlad29e632006-06-21 17:45:17 +0000658- The compiler module now correctly compiles the new try-except-finally
659 statement (bug #1509132).
660
Neal Norwitz60373cd2006-06-22 06:30:50 +0000661- The wsgiref package is now installed properly on Unix.
662
Vinay Sajip28e57612006-07-01 10:45:20 +0000663- A bug was fixed in logging.config.fileConfig() which caused a crash on
664 shutdown when fileConfig() was called multiple times.
665
Gerhard Häring762fbd32006-07-02 17:48:30 +0000666- The sqlite3 module did cut off data from the SQLite database at the first
667 null character before sending it to a custom converter. This has been fixed
668 now.

671-----------------
672
Tim Peters112aad32006-07-19 00:03:19 +0000673- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
674 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
675 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000676
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000677- Assigning None to pointer type fields in ctypes structures possible
678 overwrote the wrong fields, this is fixed now.
679
680- Fixed a segfault in _ctypes when ctypes.wintypes were imported
681 on non-Windows platforms.
682
683- Bug #1518190: The ctypes.c_void_p constructor now accepts any
684 integer or long, without range checking.
685
686- Patch #1517790: It is now possible to use custom objects in the ctypes
687 foreign function argtypes sequence as long as they provide a from_param
688 method, no longer is it required that the object is a ctypes type.
689
690- The '_ctypes' extension module now works when Python is configured
691 with the --without-threads option.
692
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000693- Bug #1513646: os.access on Windows now correctly determines write

706
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000707- Automate Windows build process for the Win64 SSL module.
708
Tim Peters32a83612006-07-10 21:08:24 +0000709- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000710 Previously, the slight difference could cause compilation errors of the
711 'zlib' module on systems with more than one version of zlib.
712
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000713- The MSI compileall step was fixed to also support a TARGETDIR
714 with spaces in it.

744Core and builtins
745-----------------
746
Georg Brandla56b9152006-06-19 06:35:54 +0000747- Patch #1507676: Error messages returned by invalid abstract object operations
748 (such as iterating over an integer) have been improved and now include the
749 type of the offending object to help with debugging.
750
Brett Cannonea3912b2006-06-13 21:46:41 +0000751- Bug #992017: A classic class that defined a __coerce__() method that returned
752 its arguments swapped would infinitely recurse and segfault the interpreter.
753
Neal Norwitz909eb122006-06-12 02:13:21 +0000754- Fix the socket tests so they can be run concurrently.
755
Neal Norwitzb9845e72006-06-12 02:11:18 +0000756- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000757 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000758
Brett Cannon22565aa2006-06-09 22:31:23 +0000759- Bug #532646: object.__call__() will continue looking for the __call__
760 attribute on objects until one without one is found. This leads to recursion
761 when you take a class and set its __call__ attribute to an instance of the
762 class. Originally fixed for classic classes, but this fix is for new-style.
763 Removes the infinite_rec_3 crasher.
764
Georg Brandl24250812006-06-09 18:45:48 +0000765- The string and unicode methods startswith() and endswith() now accept
766 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
767
Brett Cannonde3b0522006-06-08 17:00:45 +0000768- Buffer objects, at the C level, never used the char buffer
769 implementation even when the char buffer for the wrapped object was
770 explicitly requested (originally returned the read or write buffer).
771 Now a TypeError is raised if the char buffer is not present but is
772 requested.
773
Georg Brandlddbaa662006-06-04 21:56:52 +0000774- Patch #1346214: Statements like "if 0: suite" are now again optimized
775 away like they were in Python 2.4.
776
Georg Brandlb7c8f542006-05-27 12:30:25 +0000777- Builtin exceptions are now full-blown new-style classes instead of
778 instances pretending to be classes, which speeds up exception handling
779 by about 80% in comparison to 2.5a2.
780
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000781- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
782 Unicode 4.1.
783
Georg Brandlf4ef1162006-05-26 18:03:31 +0000784- Patch #921466: sys.path_importer_cache is now used to cache valid and
785 invalid file paths for the built-in import machinery which leads to
786 fewer open calls on startup.
787
Tim Peters696cf432006-05-24 21:10:40 +0000788- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
789 of-2 bases. The largest speedup is for inputs with about 1000 decimal
790 digits. Conversion from non-power-of-2 bases remains quadratic-time in
791 the number of input digits (it was and remains linear-time for bases
792 2, 4, 8, 16 and 32).
793
Tim Petersb713ec22006-05-23 18:45:30 +0000794- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
795 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
796 an integer close to ``sys.maxint``. This was repaired by patch
797 #1335972, which also gives a nice speedup.
798
Richard Jonescebbefc2006-05-23 18:28:17 +0000799- Patch #1337051: reduced size of frame objects.
800
801- PyErr_NewException now accepts a tuple of base classes as its
802 "base" parameter.
803
Richard Jones7c88dcc2006-05-23 10:37:38 +0000804- Patch #876206: function call speedup by retaining allocated frame
805 objects.
806
Georg Brandl7b90e162006-05-18 07:01:27 +0000807- Bug #1462152: file() now checks more thoroughly for invalid mode
808 strings and removes a possible "U" before passing the mode to the
809 C library function.
810
Neal Norwitz1004a532006-05-15 07:17:23 +0000811- Patch #1488312, Fix memory alignment problem on SPARC in unicode
812
Neal Norwitz373f0a72006-05-15 07:04:36 +0000813- Bug #1487966: Fix SystemError with conditional expression in assignment
814
Martin v. Löwis879768d2006-05-11 13:28:43 +0000815- WindowsError now has two error code attributes: errno, which carries
816 the error values from errno.h, and winerror, which carries the error
817 values from winerror.h. Previous versions put the winerror.h values
818 (from GetLastError()) into the errno attribute.
819
Martin v. Löwis77736712006-05-04 05:51:03 +0000820- Patch #1475845: Raise IndentationError for unexpected indent.
821
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000822- Patch #1479181: split open() and file() from being aliases for each other.
823
Tim Peters44bd9862006-06-01 13:49:23 +0000824- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
825 methods were always silently ignored by dictionaries when comparing keys.
826 They are now passed through (except when using the C API function
827 ``PyDict_GetItem()``, whose semantics did not change).
828
829- Bug #1456209: In some obscure cases it was possible for a class with a
830 custom ``__eq__()`` method to confuse dict internals when class instances
831 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
832 No, you don't have any code that did this ;-)

842 buffer and actually follow its documentation.
843
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000844- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
845
Nick Coghlanc649ec52006-05-29 12:43:05 +0000846- Patch #1478788 (modified version): The functional extension module has
847 been renamed to _functools and a functools Python wrapper module added.
848 This provides a home for additional function related utilities that are
849 not specifically about functional programming. See PEP 309.
850
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000851- Patch #1493701: performance enhancements for struct module.

860
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000861- On Win32, os.listdir now supports arbitrarily-long Unicode path names
862 (up to the system limit of 32K characters).
863
864- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
865 As a result, these functions now raise WindowsError instead of OSError.
866
Tim Peters7a822da2006-05-25 21:50:17 +0000867- ``time.clock()`` on Win64 should use the high-performance Windows
868 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
869 Windows platforms).
870
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000871- Calling Tk_Init twice is refused if the first call failed as that
872 may deadlock.
873
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000874- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
875 accept it without potentially using an uninitialized pointer.
876
877- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
878 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Vinay Sajip28e57612006-07-01 10:45:20 +0000896 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000897 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
898 database calls that would previously deadlock. [SF python bug #775414]

Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000916- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
917
Martin v. Löwis337487e2006-06-17 09:15:14 +0000918- Patch #763580: Add name and value arguments to Tkinter variable
919 classes.
920
Georg Brandl83cc0d02006-06-14 08:50:03 +0000921- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
922 mime.types file for determining MIME types.
923
Georg Brandl2605ca82006-06-14 06:08:31 +0000924- Bug #1339007: Shelf objects now don't raise an exception in their
925 __del__ method when initialization failed.
926
Martin v. Löwisd8251432006-06-14 05:21:04 +0000927- Patch #1455898: The MBCS codec now supports the incremental mode for
928 double-byte encodings.
929
Tim Peters43898b42006-06-14 04:09:25 +0000930- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
931 guarantee that adjacent triples in the return list always describe
932 non-adjacent blocks. Previously, a pair of matching blocks could end
933 up being described by multiple adjacent triples that formed a partition
934 of the matching pair.
935
Greg Ward0e0c9f42006-06-11 16:24:11 +0000936- Bug #1498146: fix optparse to handle Unicode strings in option help,
937 description, and epilog.
938
Greg Wardd1c797e2006-06-11 14:42:41 +0000939- Bug #1366250: minor optparse documentation error.
940
Greg Ward7f547402006-06-11 00:40:49 +0000941- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
942 clarify docs.
943
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000944- The wsgiref package has been added to the standard library.
945
Nick Coghlan676725d2006-06-08 13:54:49 +0000946- The functions update_wrapper() and wraps() have been added to the functools
947 module. These make it easier to copy relevant metadata from the original
948 function when writing wrapper functions.
949
Tim Petersd6a9eef2006-06-05 01:48:21 +0000950- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
951 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000952
Martin v. Löwis3f767792006-06-04 19:36:28 +0000953- Patch #1359618: Speed up charmap encoder by using a trie structure
954 for lookup.
955
Tim Petersd609b1a2006-06-02 23:22:51 +0000956- The functions in the ``pprint`` module now sort dictionaries by key
957 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
958 if and only if its display required more than one line, although that
959 wasn't documented. The new behavior increases predictability; e.g.,
960 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
961
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000962- Patch #1497027: try HTTP digest auth before basic auth in urllib2
963 (thanks for J. J. Lee).
964
Georg Brandl2b330372006-05-28 20:23:12 +0000965- Patch #1496206: improve urllib2 handling of passwords with respect to
966 default HTTP and HTTPS ports.
967
George Yoshidaf3c65de2006-05-28 16:39:09 +0000968- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
969
Bob Ippolito7298f272006-05-23 18:43:47 +0000970- Patch #1281707: speed up gzip.readline.
971
Georg Brandlb89316f2006-05-17 15:51:16 +0000972- Patch #1180296: Two new functions were added to the locale module:
973 format_string() to get the effect of "format % items" but locale-aware,
974 and currency() to format a monetary number with currency sign.
975
Georg Brandle3a25832006-05-17 14:56:04 +0000976- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
977 and several features added, such as speed and geometry control.
978
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000979- Patch #1488881: add support for external file objects in bz2 compressed
980 tarfiles.
981
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000982- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
983 stdout arguments, making it possible to redirect input and output
984 for remote debugging.
985
986- Patch #1484695: Update the tarfile module to version 0.8. This fixes
987 a couple of issues, notably handling of long file names using the
988 GNU LONGNAME extension.
989
990- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
991 new flag when ``name`` is already the name of an option flag.
992
993- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
994 package.
995
996- Patch #1472854: make the rlcompleter.Completer class usable on non-
997 UNIX platforms.
998
999- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1000
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001001- Bug #1472827: correctly escape newlines and tabs in attribute values in
1002 the saxutils.XMLGenerator class.

1037Core and builtins
1038-----------------
1039
Thomas Heller1b046642006-04-18 18:51:06 +00001040- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1041 by converting these apis from macros into exported functions again:
1042
1043 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1044 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1045 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1046 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1047 PyRun_String Py_CompileString
1048
Martin v. Löwis45294a92006-04-18 06:24:08 +00001049- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1050
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001051- All uses of PyStructSequence_InitType have been changed to initialize
1052 the type objects only once, even if the interpreter is initialized
1053 multiple times.
1054
Neal Norwitz61546162006-04-14 05:20:28 +00001055- Bug #1454485, array.array('u') could crash the interpreter. This was
1056 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1057 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1058
1059- Py_UNICODE is unsigned. It was always documented as unsigned, but
1060 due to a bug had a signed value in previous versions.
1061
Tim Peters3a5e8b12006-04-11 01:44:07 +00001062- Patch #837242: ``id()`` of any Python object always gives a positive
1063 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1064 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001065 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001066 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001067
Tim Peters3a5e8b12006-04-11 01:44:07 +00001068 def __hash__(self):
1069 return id(self) # WRONG
1070
1071 because a hash result must be a (short) Python int but it was always
1072 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001073 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001074 was always usable as a hash value before this patch. That's no longer
1075 necessarily so.
1076
1077- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001078 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001079 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001080 #1454844)
1081
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001082- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1083 involving generators that have paused outside of any ``try`` or ``with``
1084 blocks. (In 2.5a1, a paused generator that was part of a reference
1085 cycle could not be garbage collected, regardless of whether it was
1086 paused in a ``try`` or ``with`` block.)

Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001094- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1095 fails with an error condition.
1096
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001097- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.

1099- Bug #1117761: bsddb.*open() no longer raises an exception when using
1100 the cachesize parameter.
1101
1102- Bug #1149413: bsddb.*open() no longer raises an exception when using
1103 a temporary db (file=None) with the 'n' flag to truncate on open.
1104
1105- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1106 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001107
Armin Rigoa9017c32006-04-19 11:50:27 +00001108- Patch #1062014: AF_UNIX sockets under Linux have a special
1109 abstract namespace that is now fully supported.

Peter Astrand7d1d4362006-07-14 14:04:45 +00001114- Bug #1223937: subprocess.CalledProcessError reports the exit status
1115 of the process using the returncode attribute, instead of
1116 abusing errno.
1117
Tim Peters711bf302006-04-25 03:31:36 +00001118- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1119 a doctest to be skipped (the code is not run, and the expected output
1120 or exception is ignored).
1121
Nick Coghlanda2268f2006-04-24 04:37:15 +00001122- Fixed contextlib.nested to cope with exceptions being raised and
1123 caught inside exit handlers.
1124
Greg Wardab05edc2006-04-23 03:47:58 +00001125- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1126 hex, octal, or binary; add ``append_const`` action; keep going if
1127 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1128 added ``epilog`` for better help generation).
1129
Tim Peters21fbd572006-04-21 21:18:10 +00001130- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1131 called from a thread spawned as a side effect of importing a module.
1132
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001133- The pydoc module now supports documenting packages contained in
1134 .zip or .egg files.
1135
1136- The pkgutil module now has several new utility functions, such
1137 as ``walk_packages()`` to support working with packages that are either
1138 in the filesystem or zip files.
1139
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001140- The mailbox module can now modify and delete messages from
1141 mailboxes, in addition to simply reading them. Thanks to Gregory
1142 K. Johnson for writing the code, and to the 2005 Google Summer of
1143 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001144
Tim Petersc7605f22006-04-17 21:12:33 +00001145- The ``__del__`` method of class ``local`` in module ``_threading_local``
1146 returned before accomplishing any of its intended cleanup.
1147
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001148- Patch #790710: Add breakpoint command lists in pdb.
1149
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001150- Patch #1063914: Add Tkinter.Misc.clipboard_get().

1153
Anthony Baxtere29002c2006-04-12 12:07:31 +00001154- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1155 Windows. Bug #1469163.
1156
Phillip J. Eby47032112006-04-11 01:07:43 +00001157- The warnings, linecache, inspect, traceback, site, and doctest modules
1158 were updated to work correctly with modules imported from zipfiles or
1159 via other PEP 302 __loader__ objects.
1160
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001161- Patch #1467770: Reduce usage of subprocess._active to processes which

Martin v. Löwis4be4e652006-04-17 19:25:49 +00001174- The Makefile now has a reindent target, which runs reindent.py on
1175 the library.
1176
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001177- Patch #1470875: Building Python with MS Free Compiler

1182 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001183 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001184 CXX from --with-cxx-main, see description in README.
1185

1189
Tim Peters8931ff12006-05-13 23:28:20 +00001190- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1191 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1192 and "%zu" for unsigned integers of type ``size_t``.
1193
Anthony Baxter51bcb682006-04-05 14:51:42 +00001194Tests
1195-----
1196
Nick Coghlanda2268f2006-04-24 04:37:15 +00001197- test_contextlib now checks contextlib.nested can cope with exceptions
1198 being raised and caught inside exit handlers.
1199
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001200- test_cmd_line now checks operation of the -m and -c command switches
1201
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001202- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1203 it separately and by hand. It also wasn't cleaning up its changes to
1204 the current Decimal context.
1205
Thomas Woutersabd08882006-04-26 15:53:30 +00001206- regrtest.py now has a -M option to run tests that test the new limits of
1207 containers, on 64-bit architectures. Running these tests is only sensible
1208 on 64-bit machines with more than two gigabytes of memory. The argument
1209 passed is the maximum amount of memory for the tests to use.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001230What's New in Python 2.5 alpha 1?
1231=================================
1232
Anthony Baxterebed3f62006-04-03 15:03:44 +00001233*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001234
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001235Core and builtins
1236-----------------
1237
Nick Coghlan43832302006-04-23 17:04:07 +00001238- PEP 338: -m command line switch now delegates to runpy.run_module
1239 allowing it to support modules in packages and zipfiles
1240
Martin v. Löwisc661b882006-04-20 04:54:23 +00001241- On Windows, .DLL is not an accepted file name extension for
1242 extension modules anymore; extensions are only found if they
1243 end in .PYD.
1244
Martin v. Löwisea62d252006-04-03 10:56:49 +00001245- Bug #1421664: sys.stderr.encoding is now set to the same value as
1246 sys.stdout.encoding.
1247
Neal Norwitz92e212f2006-04-03 04:48:37 +00001248- __import__ accepts keyword arguments.
1249
Georg Brandlccadf842006-03-31 18:54:53 +00001250- Patch #1460496: round() now accepts keyword arguments.
1251
Anthony Baxter262c00a2006-03-30 10:53:17 +00001252- Fixed bug #1459029 - unicode reprs were double-escaped.
1253
Hye-Shik Changd478f342006-03-23 12:32:36 +00001254- Patch #1396919: The system scope threads are reenabled on FreeBSD
1255 5.4 and later versions.
1256
Neal Norwitze98ccf62006-03-23 05:39:47 +00001257- Bug #1115379: Compiling a Unicode string with an encoding declaration
1258 now gives a SyntaxError.
1259
Georg Brandlabd1ff82006-03-18 07:59:59 +00001260- Previously, Python code had no easy way to access the contents of a
1261 cell object. Now, a ``cell_contents`` attribute has been added
1262 (closes patch #1170323).
1263
Tim Peterscf79aac2006-03-16 01:14:46 +00001264- Patch #1123430: Python's small-object allocator now returns an arena to
1265 the system ``free()`` when all memory within an arena becomes unused
1266 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1267 freed. Some applications will see a drop in virtual memory size now,
1268 especially long-running applications that, from time to time, temporarily
1269 use a large number of small objects. Note that when Python returns an
1270 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001271 platform C library will in turn return that memory to the operating system.
1272 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001273 appears to be effective at least on Microsoft C and gcc-based systems.
1274 Thanks to Evan Jones for hard work and patience.
1275
Georg Brandl533ff6f2006-03-08 18:09:27 +00001276- Patch #1434038: property() now uses the getter's docstring if there is
1277 no "doc" argument given. This makes it possible to legitimately use
1278 property() as a decorator to produce a read-only property.
1279
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001280- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1281 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1282 of requiring an int or long in slicing and a few other contexts, enabling
1283 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1284
Neal Norwitz995acdf2006-03-07 05:01:00 +00001285- Fixed various bugs reported by Coverity's Prevent tool.
1286
Brett Cannonbf364092006-03-01 04:25:17 +00001287- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1288 new exception base class, BaseException, which has a new message attribute.
1289 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1290 Raising a string exception now raises a DeprecationWarning.
1291
Thomas Woutersfb609f42006-02-28 16:37:25 +00001292- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1293 explicitly relative, using 'from .module import name' to mean 'from the same
1294 package as this module is in. Imports without dots still default to the
1295 old relative-then-absolute, unless 'from __future__ import
1296 absolute_import' is used.
1297
Brett Cannona7446e32006-02-27 23:39:10 +00001298- Properly check if 'warnings' raises an exception (usually when a filter set
1299 to "error" is triggered) when raising a warning for raising string
1300 exceptions.
1301
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001302- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001303 The name was removed from Include/code.h.
1304
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001305- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001306
Guido van Rossum1968ad32006-02-25 22:38:04 +00001307- Patch 1433928:
1308 - The copy module now "copies" function objects (as atomic objects).
1309 - dict.__getitem__ now looks for a __missing__ hook before raising
1310 KeyError.
1311
Tim Peters84ef21c2006-02-28 20:39:06 +00001312- PEP 343: with statement implemented. Needs ``from __future__ import
1313 with_statement``. Use of 'with' as a variable will generate a warning.
1314 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001315 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001316 The following objects have __context__ methods:
1317 - The built-in file type.
1318 - The thread.LockType type.
1319 - The following types defined by the threading module:
1320 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1321 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001322
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001323- Fix the encodings package codec search function to only search
1324 inside its own package. Fixes problem reported in patch #1433198.
1325
1326 Note: Codec packages should implement and register their own
1327 codec search function. PEP 100 has the details.
1328
Tim Peters9ea89d22006-06-04 03:26:02 +00001329- PEP 353: Using ``Py_ssize_t`` as the index type.
1330
1331- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1332 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1333 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1334 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1335 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001336
Neal Norwitzfc76d632006-01-10 06:03:13 +00001337- Patch #1400181, fix unicode string formatting to not use the locale.
1338 This is how string objects work. u'%f' could use , instead of .
1339 for the decimal point. Now both strings and unicode always use periods.
1340
Neal Norwitz671b9e32006-01-09 07:07:12 +00001341- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1342 configure would break checking curses.h.
1343
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001344- Bug #959576: The pwd module is now builtin. This allows Python to be
1345 built on UNIX platforms without $HOME set.
1346
Neal Norwitzc10978f2005-12-19 06:07:16 +00001347- Bug #1072182, fix some potential problems if characters are signed.
1348
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001349- Bug #889500, fix line number on SyntaxWarning for global declarations.
1350
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001351- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1352
Neal Norwitze7214a12005-12-18 05:03:17 +00001353- Support for converting hex strings to floats no longer works.
1354 This was not portable. float('0x3') now raises a ValueError.
1355
Barry Warsaw2a38a862005-12-18 01:27:35 +00001356- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001357 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001358 is now displayed in interactive prompt banner.
1359
Georg Brandlfa166682005-12-17 21:45:17 +00001360- Implementation of PEP 341 - Unification of try/except and try/finally.
1361 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001362 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001363
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001364- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1365 now encodes backslash correctly.
1366
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001367- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1368
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001369- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001370 and long longs.
1371
Neal Norwitz67715f02005-11-09 06:59:35 +00001372- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001373 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001374 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001375
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001376- Replaced most Unicode charmap codecs with new ones using the
1377 new Unicode translate string feature in the builtin charmap
1378 codec; the codecs were created from the mapping tables available
1379 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1380 encodings now include a mapping for the Apple logo)
1381
Tim Peterse3547fd2005-12-16 23:13:57 +00001382- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001383
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001384- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001385
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001386- A new AST parser implementation was completed. The abstract
1387 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001388 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001389
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001390- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001391 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1392
Neal Norwitz708e51a2005-10-03 04:48:15 +00001393- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1394
Neal Norwitz11bd1192005-10-03 00:54:56 +00001395- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1396 Provide a warning when a directory is passed on the command line.
1397
Neal Norwitz40d37812005-10-02 01:48:49 +00001398- Fix segfault with invalid coding.
1399
1400- SF bug #772896: unknown encoding results in MemoryError.
1401
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001402- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001403 supported a __len__() method which evaluated to False when the iterator
1404 was empty.
1405
Guido van Rossum630db602005-09-20 18:49:54 +00001406- On 64-bit platforms, when __len__() returns a value that cannot be
1407 represented as a C int, raise OverflowError.
1408
Skip Montanarof8948ca2005-09-19 03:54:46 +00001409- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001410 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001411
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001412- SF bug #893549: parsing keyword arguments was broken with a few format
1413 codes.
1414
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001415- Changes donated by Elemental Security to make it work on AIX 5.3
1416 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1417 bug #105470: test_pwd fails on 64bit system (Opteron).
1418
Guido van Rossum539c6622005-09-14 17:49:54 +00001419- Changes donated by Elemental Security to make it work on HP-UX 11 on
1420 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1421
Georg Brandl4550b8d2005-08-26 06:43:52 +00001422- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001423 (fixes bug #1119418).
1424
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001425- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1426
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001427- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1428 exceptions that cause a function to exit.
1429
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001430- The implementation of set() and frozenset() was revised to use its
1431 own internal data structure. Memory consumption is reduced by 1/3
1432 and there are modest speed-ups as well. The API is unchanged.
1433
Tim Petersde7990b2005-07-17 23:45:23 +00001434- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1435
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001436- SF bug #1229429: PyObject_CallMethod failed to decrement some
1437 reference counts in some error exit cases.
1438
Tim Petersecc6e6a2005-07-10 22:30:55 +00001439- SF bug #1185883: Python's small-object memory allocator took over
1440 a block managed by the platform C library whenever a realloc specified
1441 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001442 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001443 portable way to copy data from the C-managed block into Python's
1444 small-object space without risking a memory fault. Python's small-object
1445 realloc now leaves such blocks under the control of the platform C
1446 realloc.
1447
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001448- SF bug #1232517: An overflow error was not detected properly when
1449 attempting to convert a large float to an int in os.utime().
1450
Raymond Hettinger3296e692005-06-29 23:29:56 +00001451- SF bug #1224347: hex longs now print with lowercase letters just
1452 like their int counterparts.
1453
Michael W. Hudson188d4362005-06-20 16:52:57 +00001454- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1455 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1456 interpreter states; back out that fix and do a better job (see
1457 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1458 for a longer write-up of the problem).
1459
Michael W. Hudsondf888462005-06-03 14:41:55 +00001460- SF patch #1180995: marshal now uses a binary format by default when
1461 serializing floats.
1462
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001463- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1464 the routines that promise to produce IEEE 754 binary representations
1465 of floats now simply copy bytes around.
1466
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001467- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1468 278.
1469
Brett Cannonc3647ac2005-04-26 03:45:26 +00001470- patch #1109424: int, long, float, complex, and unicode now check for the
1471 proper magic slot for type conversions when subclassed. Previously the
1472 magic slot was ignored during conversion. Semantics now match the way
1473 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001474 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001475 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001476 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001477
Barry Warsawc8d907c2005-04-19 23:43:40 +00001478- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1479 NULL, now raise an AttributeError when attempting to set or delete the
1480 attribute. Previously a TypeError was raised, but this was inconsistent
1481 with the equivalent pure-Python implementation.
1482
Michael W. Hudson774479c2005-04-18 08:46:17 +00001483- It is now safe to call PyGILState_Release() before
1484 PyEval_InitThreads() (note that if there is reason to believe there
1485 are multiple threads around you still must call PyEval_InitThreads()
1486 before using the Python API; this fix is for extension modules that
1487 have no way of knowing if Python is multi-threaded yet).
1488
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001489- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1490 disabled caused a crash.
1491
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001492- Bug #1165306: instancemethod_new allowed the creation of a method
1493 with im_class == im_self == NULL, which caused a crash when called.

1541 current thread state when the auto-GIL-state machinery knows about
1542 it (since the thread state is being deleted, continuing to remember it
1543 can't help, but can hurt if another thread happens to get created with
1544 the same thread id).

Tim Petersc17976e2006-04-01 00:26:53 +00001759- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1760 aren't officially supported here, and trying to use them will probably
1761 raise an exception some day. But dicts have been allowed, and "mostly
1762 worked", so support for them won't go away without warning.
1763
Georg Brandl338ef7d2006-03-31 18:42:16 +00001764- Bug #1445068: getpass.getpass() can now be given an explicit stream

Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001775- Queue.Queue objects now support .task_done() and .join() methods
1776 to make it easier to monitor when daemon threads have completed
1777 processing all enqueued tasks. Patch #1455676.
1778
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001779- popen2.Popen objects now preserve the command in a .cmd attribute.

1782
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001783- email 4.0 package now integrated. This is largely the same as the email 3.0
1784 package that was included in Python 2.3, except that PEP 8 module names are
1785 now used (e.g. mail.message instead of email.Message). The MIME classes
1786 have been moved to a subpackage (e.g. email.mime.text instead of
1787 email.MIMEText). The old names are still supported for now. Several
1788 deprecated Message methods have been removed and lots of bugs have been
1789 fixed. More details can be found in the email package documentation.
1790
Walter Dörwald40108c92006-03-27 08:15:44 +00001791- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1792 (a subclass of tuple) that provides incremental decoders and encoders
1793 (a way to use stateful codecs without the stream API). Python functions
1794 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1795 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1796 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001797
Walter Dörwald067db482006-03-15 22:17:27 +00001798- Patch #1359365: Calling next() on a closed StringIO.String object raises
1799 a ValueError instead of a StopIteration now (like file and cString.String do).
1800 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1801 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001802
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001803- A regrtest option -w was added to re-run failed tests in verbose mode.

1809 grew an optional 'generation' argument.
1810
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00001811- A library msilib to generate Windows Installer files, and a distutils

Tim Peterse3547fd2005-12-16 23:13:57 +00001875 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1876 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1877 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1878 Ronald L. Rivest offered this advice for Python:
1879
1880 "The consensus of researchers in this area (at least as
1881 expressed at the NIST Hash Function Workshop 10/31/05),
1882 is that SHA-256 is a good choice for the time being, but
1883 that research should continue, and other alternatives may
1884 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001885
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001886- Added a subset of Fredrik Lundh's ElementTree package. Available

2044
Guido van Rossumd0641422005-02-03 15:01:24 +00002045- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2046 disables recursive traversal through instance attributes, which can
2047 be exploited in various ways.
2048
Tim Peterse3547fd2005-12-16 23:13:57 +00002049- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002050 flags on the HTTP listening socket.
2051
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002052- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2053 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2054
Fred Drakefbdeaad2006-07-29 16:56:15 +00002055- Patches #893642, #1039083: add allow_none, encoding arguments to

2061
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002062- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2063
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002064- Enhancements to the csv module:
2065
2066 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002067 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002068 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002069 + Dialect parameter parsing has been re-implemented to improve error
2070 reporting.
2071 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2072 dictates.
2073 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002074 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002075 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002076 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2077 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002078 + reader now allows \r characters to be quoted (previously it only allowed
2079 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002080 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002081 + Dialect classes passed to the module are no longer instantiated by
2082 the module before being parsed (the former validation scheme required
2083 this, but the mechanism was unreliable).
2084 + The dialect registry now contains instances of the internal
2085 C-coded dialect type, rather than references to python objects.
2086 + the internal c-coded dialect type is now immutable.
2087 + register_dialect now accepts the same keyword dialect specifications
2088 as the reader and writer, allowing the user to register dialects
2089 without first creating a dialect class.
2090 + a configurable limit to the size of parsed fields has been added -
2091 previously, an unmatched quote character could result in the entire
2092 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002093 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002094 the parser field size limit (returning the former limit). The initial
2095 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002096 + A line_num attribute has been added to the reader object, which tracks
2097 the number of lines read from the source iterator. This is not
2098 the same as the number of records returned, as records can span
2099 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002100 + reader and writer objects were not being registered with the cyclic-GC.
2101 This has been fixed.
2102
Brett Cannone6539c42005-01-08 02:43:53 +00002103- _DummyThread objects in the threading module now delete self.__block that is
2104 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2105 lock primitives tend to be limited in number and thus should not be wasted on
2106 a _DummyThread object. Fixes bug #1089632.
2107
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002108- The imghdr module now detects Exif files.
2109
Raymond Hettinger6065d322004-12-20 23:51:53 +00002110- StringIO.truncate() now correctly adjusts the size attribute.
2111 (Bug #951915).
2112
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002113- locale.py now uses an updated locale alias table (built using
2114 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2115 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002116 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002117
Raymond Hettinger3557f422004-12-07 12:02:02 +00002118- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2119
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002120- the pickle module no longer accepts the deprecated None option in the
2121 args tuple returned by __reduce__().
2122
Brett Cannon84667c02004-12-07 03:25:18 +00002123- optparse now optionally imports gettext. This allows its use in setup.py.
2124
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002125- the pickle module no longer uses the deprecated bin parameter.
2126
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002127- the shelve module no longer uses the deprecated binary parameter.
2128
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002129- the pstats module no longer uses the deprecated ignore() method.
2130
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002131- the filecmp module no longer uses the deprecated use_statcache argument.
2132
Raymond Hettinger664347b2004-12-04 21:21:53 +00002133- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2134 extended or overridden by subclasses. Formerly, the subclassed method would
2135 be ignored by the rest of the module. (Bug #1078905).
2136
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002137- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002138 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002139
Walter Dörwald36733692004-12-22 12:50:50 +00002140- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2141 once when a size argument is given. This prevents a buffer overflow in the
2142 tokenizer with very long source lines.
2143
Barry Warsaw538561e2006-01-01 21:48:54 +00002144- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2145 immediately after creating the object, without any intervening
2146 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002147
Skip Montanaro05885812005-01-16 20:48:27 +00002148- The reconvert.quote function can now emit triple-quoted strings. The
2149 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002150
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002151- ``UserString.MutableString`` now supports negative indices in
2152 ``__setitem__`` and ``__delitem__``
2153
Greg Ward40407942005-03-05 02:53:17 +00002154- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2155 correctly.
2156
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002157- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2158 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2159 character even if the user has passed a size parameter to get a proper
2160 line ending. Remove the special handling of a "\r\n" that has been split
2161 between two lines.
2162
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002163- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2164 about illegal code points. The codec now supports PEP 293 style error
2165 handlers.
2166
Walter Dörwald78a78b02005-09-01 12:04:29 +00002167- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002168 from the input stream, so that the output is a byte string in the correct
2169 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002170
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002171- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2172 considering it exactly like a '*'.
2173
Walter Dörwald007f8df2005-10-09 19:42:27 +00002174- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2175 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002176
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002177- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2178
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002179- Patch #1413711: Certain patterns of differences were making difflib
2180 touch the recursion limit.
2181
Walter Dörwald58917a62006-03-31 15:26:22 +00002182- Bug #947906: An object oriented interface has been added to the calendar
2183 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002184 called as a script (e.g. via ``python -mcalendar``). Localized month and
2185 weekday names can be ouput (even if an exotic encoding is used) using
2186 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002187
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002188Build
2189-----
2190
Neal Norwitz602d3392006-03-31 08:21:40 +00002191- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2192 by using -mieee gcc option.
2193
Martin v. Löwis86d66262006-02-17 08:40:11 +00002194- Patch #1432345: Make python compile on DragonFly.
2195
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002196- Build support for Win64-AMD64 was added.
2197
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002198- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2199
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002200- Patch #881820: look for openpty and forkpty also in libbsd.
2201
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002202- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2203 The zlib module is now builtin on Windows.
2204
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002205- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2206
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002207- Bug #1189330: configure did not correctly determine the necessary
2208 value of LINKCC if python was built with GCC 4.0.
2209
Trent Mick8321b422005-07-26 02:29:21 +00002210- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2211 vulnerability in zlib 1.2.1 and 1.2.2.
2212
Brett Cannon08cd5982005-04-24 22:26:38 +00002213- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2214 flags that change binary compatibility. Changes were also made to
2215 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002216 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002217
Bob Ippolitoed233462005-03-29 13:47:59 +00002218- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2219 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2220 no longer exists). This configure patch makes things right.
2221
Martin v. Löwise2713be2005-03-08 15:03:08 +00002222- Bug #1158607: Build with --disable-unicode again.
2223
Brett Cannon46d96232005-02-16 00:07:19 +00002224- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2225 defined. Discovered as a result of not being able to build on OS X.
2226
Brett Cannon516592f2004-12-07 00:42:59 +00002227- setup.py now uses the directories specified in LDFLAGS using the -L option
2228 and in CPPFLAGS using the -I option for adding library and include
2229 directories, respectively, for compiling extension modules against. This has
2230 led to the core being compiled using the values in CPPFLAGS. It also removes
2231 the need for the special-casing of both DarwinPorts and Fink for darwin since
2232 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2233 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2234 Fink, ``-I/opt/local/include`` for DarwinPorts).
2235
Brett Cannon43802422005-02-10 20:48:03 +00002236- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2237 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2238 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2239 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002241C API
2242-----
2243
Tim Petersc9d78aa2006-03-26 23:27:58 +00002244- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2245 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2246 is obtained via the ``PyObject_`` family, it must be released via the
2247 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2248 always been officially true, but when Python's small-object allocator was
2249 introduced, an attempt was made to cater to a few extension modules
2250 discovered at the time that obtained memory via ``PyObject_New`` but
2251 released it via ``PyMem_DEL``. It's years later, and if such code still
2252 exists it will fail now (probably with segfaults, but calling wrong
2253 low-level memory management functions can yield many symptoms).
2254
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002255- Added a C API for set and frozenset objects.
2256
Raymond Hettinger66517482004-12-03 11:45:13 +00002257- Removed PyRange_New().
2258
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002259- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2260 mapping argument now. This string is used as a mapping table. Byte values
2261 greater than the length of the string and 0xFFFE are treated as undefined
2262 mappings.
