20-----------------
21
Brett Cannon19d76c52006-09-09 07:18:44 +000022- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
23 allows calling unicode() on exceptions classes directly to succeed.
24
Georg Brandlecab6232006-09-06 06:47:02 +000025- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
26 Also make sure that every exception class has __module__ set to
27 'exceptions'.
28
Georg Brandl37a9e572006-09-06 06:09:34 +000029- Bug #1550983: emit better error messages for erroneous relative

Neal Norwitz29a5fdb2006-09-05 02:21:38 +000040- The return tuple from str.rpartition(sep) is (tail, sep, head) where
41 head is the original string if sep was not found.
42
Neal Norwitz3b3aae02006-09-05 03:56:01 +000043- Bug #1520864: unpacking singleton tuples in list comprehensions and
44 generator expressions (x for x, in ... ) works again. Fixing this problem
45 required changing the .pyc magic number. This means that .pyc files
46 generated before 2.5c2 will be regenerated.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000134
135Core and builtins
136-----------------
137
Neal Norwitz24b6f202006-09-05 04:43:56 +0000138- Fix infinite recursion when subclassing long and overriding __hash__.
139
140- Fix concatenation (+=) of long strings.
141
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000142- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000143 compared equal or unequal to a string and a UnicodeDecodeError
144 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000145
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000146 Instead, the equal (==) and unequal (!=) comparison operators will
147 now issue a UnicodeWarning and interpret the two objects as
148 unequal. The UnicodeWarning can be filtered as desired using
149 the warning framework, e.g. silenced completely, turned into an
150 exception, logged, etc.
151
152 Note that compare operators other than equal and unequal will still
153 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000154
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000155- Fix segfault when doing string formatting on subclasses of long.
156
157- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
158 with new-style classes.
159
160- Fix bug related to __len__ functions returning negative values with
161 classic classes.
162
163- Patch #1538606, Fix __index__() clipping. There were some problems
164 discovered with the API and how integers that didn't fit into Py_ssize_t
165 were handled. This patch attempts to provide enough alternatives
166 to effectively use __index__.
167
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000168- Bug #1536021: __hash__ may now return long int; the final hash
169 value is obtained by invoking hash on the long int.
170
Thomas Hellerab1049c2006-08-08 17:37:00 +0000171- Bug #1536786: buffer comparison could emit a RuntimeWarning.
172

174 sys.stdin is closed.
175
Thomas Heller74d36f02006-08-04 18:17:40 +0000176- On Windows, the PyErr_Warn function is now exported from
177 the Python dll again.
178
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000179- Bug #1191458: tracing over for loops now produces a line event
180 on each iteration. Fixing this problem required changing the .pyc
181 magic number. This means that .pyc files generated before 2.5c1
182 will be regenerated.
183
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000184- Bug #1333982: string/number constants were inappropriately stored
185 in the byte code and co_consts even if they were not used, ie
186 immediately popped off the stack.
187
Georg Brandle9462c72006-08-04 18:03:37 +0000188- Fixed a reference-counting problem in property().

191Library
192-------
193
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000194- Fix a bug in the ``compiler`` package that caused invalid code to be
195 generated for generator expressions.
196
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000197- The distutils version has been changed to 2.5.0. The change to
198 keep it programmatically in sync with the Python version running
199 the code (introduced in 2.5b3) has been reverted. It will continue
200 to be maintained manually as static string literal.
201
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000202- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000203 and this cannot be converted to the required C type, an exception is
204 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000205 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000206
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000207- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000208 an exception.
209
Tim Peterscbdd3502006-09-05 01:47:53 +0000210- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000211 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000212 workarounds for clocks with low resolution, to stop the code yielding
213 duplicate UUIDs.
214
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000215- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
216 before raising SystemExit, allowing IDLE to honor quit() and exit().
217
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000218- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
219
Georg Brandl7a1af772006-08-14 21:55:28 +0000220- Patch #1536071: trace.py should now find the full module name of a
221 file correctly even on Windows.
222
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000223- logging's atexit hook now runs even if the rest of the module has
224 already been cleaned up.
225
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000226- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000227
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000228- Bug #1531405, format_exception no longer raises an exception if
229 str(exception) raised an exception.
230
Neil Schemenauer06ded092006-08-04 16:20:30 +0000231- Fix a bug in the ``compiler`` package that caused invalid code to be
232 generated for nested functions.

247
Thomas Heller86720042006-08-14 11:17:48 +0000248- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
249 uses the _as_parameter_ attribute when objects are passed to foreign
250 function calls. The ctypes version number was changed to 1.0.1.
251
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000252- Bug #1530559, struct.pack raises TypeError where it used to convert.
253 Passing float arguments to struct.pack when integers are expected
254 now triggers a DeprecationWarning.
255
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000256

304Core and builtins
305-----------------
306
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000307- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000308 returned a long (see PEP 353).
309
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000310- Bug #1515471: string.replace() accepts character buffers again.
311
Neal Norwitz07aadb12006-07-30 06:55:48 +0000312- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
313 This provides the proper warning for struct.pack().
314 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
315
Neal Norwitz0d62a062006-07-30 06:53:31 +0000316- Patch #1531113: Fix augmented assignment with yield expressions.
317 Also fix a SystemError when trying to assign to yield expressions.
318
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000319- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
320 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
321 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
322 excessive filesystem operations during imports.
323
Tim Petersbc24eee2006-07-27 01:14:53 +0000324- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
325 operations on signed longs that are formally undefined by C.
326 Unfortunately, at least one compiler now cares about that, so complicated
327 the code to make that compiler happy again.
328
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000329- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
330
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000331- Patch #1232023: Stop including current directory in search
332 path on Windows.
333
Neal Norwitze1fdb322006-07-21 05:32:28 +0000334- Fix some potential crashes found with failmalloc.
335
Neal Norwitze7563102006-07-17 01:00:16 +0000336- Fix warnings reported by Klocwork's static analysis tool.
337
Neal Norwitz84be93b2006-07-16 01:50:38 +0000338- Bug #1512814, Fix incorrect lineno's when code within a function
339 had more than 255 blank lines.
340
Georg Brandl9dceedb2006-07-12 15:31:17 +0000341- Patch #1521179: Python now accepts the standard options ``--help`` and
342 ``--version`` as well as ``/?`` on Windows.
343
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000344- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000345 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000346 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000347
Tim Peters112aad32006-07-19 00:03:19 +0000348- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000349 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000350 new ``sys._current_frames()`` returns a dictionary with one entry,
351 mapping the faux "thread id" 0 to the current frame.

357-------
358
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000359- Correction of patch #1455898: In the mbcs decoder, set final=False
360 for stream decoder, but final=True for the decode function.
361
Georg Brandl07fec3a2006-08-01 18:49:24 +0000362- os.urandom no longer masks unrelated exceptions like SystemExit or
363 KeyboardInterrupt.
364
Tim Peters4643c2f2006-08-10 22:45:34 +0000365- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000366 shutil.copytree on Windows
367
Georg Brandle34ac7c2006-07-30 11:07:23 +0000368- Bug #1002398: The documentation for os.path.sameopenfile now correctly
369 refers to file descriptors, not file objects.
370
Tim Peterscbdd3502006-09-05 01:47:53 +0000371- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000372 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000373 #1513611, and probably others.
374
Georg Brandledd9b0d2006-07-29 09:33:26 +0000375- Bug #1441397: The compiler module now recognizes module and function
376 docstrings correctly as it did in Python 2.4.
377
Tim Peters6f681472006-07-27 23:44:37 +0000378- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
379 lost that tests are sorted by name before being run. This rarely
380 matters for well-written tests, but can create baffling symptoms if
381 side effects from one test to the next affect outcomes. ``DocTestFinder``
382 has been changed to sort the list of tests it returns.
383
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000384- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000385 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000386
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000387- Bug #978833: Really close underlying socket in _socketobject.close.
388
Georg Brandldb232dc2006-08-20 13:15:43 +0000389- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
390 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000391
Georg Brandlcf0c1722006-07-26 07:23:32 +0000392- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
393 to recursive calls and call it with the failing package name.
394
Martin v. Löwis0b483032006-07-25 09:53:12 +0000395- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
396
Georg Brandlc13c34c2006-07-24 14:09:56 +0000397- Patch #1515343: Fix printing of deprecated string exceptions with a
398 value in the traceback module.
399
Greg Ward48fae7a2006-07-23 16:05:51 +0000400- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
401
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000402- Patch #1524429: Use repr() instead of backticks in Tkinter again.
403
Brett Cannoncaebe222006-07-18 04:41:36 +0000404- Bug #1520914: Change time.strftime() to accept a zero for any position in its
405 argument tuple. For arguments where zero is illegal, the value is forced to
406 the minimum value that is correct. This is to support an undocumented but
407 common way people used to fill in inconsequential information in the time
408 tuple pre-2.4.
409
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000410- Patch #1220874: Update the binhex module for Mach-O.
411
Barry Warsawb110bad2006-07-21 14:51:07 +0000412- The email package has improved RFC 2231 support, specifically for
413 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
414 (name*0=<blah>) parameter continuations. This may change the types of
415 values returned from email.message.Message.get_param() and friends.
416 Specifically in some cases where non-encoded continuations were used,
417 get_param() used to return a 3-tuple of (None, None, string) whereas now it
418 will just return the string (since non-encoded continuations don't have
419 charset and language parts).
420
421 Also, whereas % values were decoded in all parameter continuations, they are
422 now only decoded in encoded parameter parts.
423
Ronald Oussoren3075e162006-07-25 20:28:55 +0000424- Bug #1517990: IDLE keybindings on MacOS X now work correctly
425
426- Bug #1517996: IDLE now longer shows the default Tk menu when a
427 path browser, class browser or debugger is the frontmost window on MacOS X
428
Barry Warsaw00decd72006-07-27 23:43:15 +0000429- Patch #1520294: Support for getset and member descriptors in types.py,
430 inspect.py, and pydoc.py. Specifically, this allows for querying the type
431 of an object against these built-in types and more importantly, for getting
432 their docstrings printed in the interactive interpreter's help() function.

436-----------------
437
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000438- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
439 a socket operation on a socket with a timeout, the exception will be
440 caught correctly. Previously, the exception was not caught.
441
Thomas Heller1393d6a2006-07-28 21:43:20 +0000442- Patch #1529514: The _ctypes extension is now compiled on more
443 openbsd target platforms.
444
Tim Peters9cab5932006-07-28 00:30:00 +0000445- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
446 a memory leak, affecting pickles and deep copies.
447
Tim Petersbc24eee2006-07-27 01:14:53 +0000448- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

450
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000451- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
452
Thomas Hellerce049a02006-07-14 17:51:14 +0000453- Patch #1521817: Index range checking on ctypes arrays containing
454 exactly one element enabled again. This allows iterating over these
455 arrays, without the need to check the array size before.
456
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000457- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000458 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000459 /dev/null in certain cases; this is now fixed.
460
Thomas Heller47d7a062006-07-12 08:43:47 +0000461- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
462 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000463
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000464- Because of a misspelled preprocessor symbol, ctypes was always
465 compiled without thread support; this is now fixed.
466
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000467- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
468 methods now allow their database parameter to be None as the
469 sleepycat API allows.
470
Matt Flemingec926502006-07-28 11:27:27 +0000471- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
472 bluetooth API compared with Linux and FreeBSD.
473
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000474Tests
475-----
476
477- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
478 how long the test file should take to play. Now accepts taking 2.93 secs
479 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
480
Georg Brandl4793aa32006-07-28 18:31:39 +0000481- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
482 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
483 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000490Mac
491---
492
493- PythonLauncher now works correctly when the path to the script contains
494 characters that are treated specially by the shell (such as quotes).
495
496- Bug #1527397: PythonLauncher now launches scripts with the working directory
497 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000498 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000499 expect.

508-----------------
509
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000510- Bug #1441486: The literal representation of -(sys.maxint - 1)
511 again evaluates to a int object, not a long.
512
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000513- Bug #1501934: The scope of global variables that are locally assigned
514 using augmented assignment is now correctly determined.
515
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000516- Bug #927248: Recursive method-wrapper objects can now safely
517 be released.
518
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000519- Bug #1417699: Reject locale-specific decimal point in float()
520 and atof().
521
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000522- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
523 omit a default "error" argument for NULL pointer. This allows
524 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000525
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000526- Bug #1519018: 'as' is now validated properly in import statements.
527
Neal Norwitz28746ab2006-07-09 22:14:42 +0000528- On 64 bit systems, int literals that use less than 64 bits are
529 now ints rather than longs.
530
Neal Norwitzed657552006-07-10 00:04:44 +0000531- Bug #1512814, Fix incorrect lineno's when code at module scope
532 started after line 256.
533
Tim Peters32a83612006-07-10 21:08:24 +0000534- New function ``sys._current_frames()`` returns a dict mapping thread
535 id to topmost thread stack frame. This is for expert use, and is
536 especially useful for debugging application deadlocks. The functionality
537 was previously available in Fazal Majid's ``threadframe`` extension
538 module, but it wasn't possible to do this in a wholly threadsafe way from
539 an extension.

548
Tim Peters32a83612006-07-10 21:08:24 +0000549- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000550 environment variable to be set in order to the SDK environment
551 for finding the compiler, include files, etc.

556
Thomas Woutersadd19112006-07-05 11:03:49 +0000557- string.Template() now correctly handles tuple-values. Previously,
558 multi-value tuples would raise an exception and single-value tuples would
559 be treated as the value they contain, instead.
560
Martin v. Löwisede77f52006-07-03 13:01:35 +0000561- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
562 even if some data are received.
563
Martin v. Löwis45482392006-07-03 12:28:58 +0000564- Bug #1267547: Put proper recursive setup.py call into the

568 degrees and radians.
569
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000570- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000571 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000572
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000573- Bug #1514703: Only setup canvas window in turtle when the canvas
574 is created.
575
Martin v. Löwis7596e832006-07-01 15:33:37 +0000576- Bug #1513223: .close() of a _socketobj now releases the underlying
577 socket again, which then gets closed as it becomes unreferenced.
578
Fred Drake10497c82006-06-29 02:57:48 +0000579- Bug #1504333: Make sgmllib support angle brackets in quoted
580 attribute values.
581
582- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
583 sgmllib ('[' and ']' were not accepted).
584
Georg Brandl1be63af2006-06-28 20:23:25 +0000585- Fix a bug in the turtle module's end_fill function.
586
Brett Cannon53ab5b72006-06-22 16:49:14 +0000587- Bug #1510580: The 'warnings' module improperly required that a Warning
588 category be either a types.ClassType and a subclass of Warning. The proper
589 check is just that it is a subclass with Warning as the documentation states.
590
Georg Brandlad29e632006-06-21 17:45:17 +0000591- The compiler module now correctly compiles the new try-except-finally
592 statement (bug #1509132).
593
Neal Norwitz60373cd2006-06-22 06:30:50 +0000594- The wsgiref package is now installed properly on Unix.
595
Vinay Sajip28e57612006-07-01 10:45:20 +0000596- A bug was fixed in logging.config.fileConfig() which caused a crash on
597 shutdown when fileConfig() was called multiple times.
598
Gerhard Häring762fbd32006-07-02 17:48:30 +0000599- The sqlite3 module did cut off data from the SQLite database at the first
600 null character before sending it to a custom converter. This has been fixed
601 now.

Tim Peters112aad32006-07-19 00:03:19 +0000606- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
607 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
608 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000609
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000610- Assigning None to pointer type fields in ctypes structures possible
611 overwrote the wrong fields, this is fixed now.

613- Fixed a segfault in _ctypes when ctypes.wintypes were imported
614 on non-Windows platforms.
615
616- Bug #1518190: The ctypes.c_void_p constructor now accepts any
617 integer or long, without range checking.
618
619- Patch #1517790: It is now possible to use custom objects in the ctypes
620 foreign function argtypes sequence as long as they provide a from_param
621 method, no longer is it required that the object is a ctypes type.
622
623- The '_ctypes' extension module now works when Python is configured
624 with the --without-threads option.
625
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000626- Bug #1513646: os.access on Windows now correctly determines write
627 access, again.
628
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000629- Bug #1512695: cPickle.loads could crash if it was interrupted with
630 a KeyboardInterrupt.
631
Neal Norwitza12aa882006-07-06 06:45:08 +0000632- Bug #1296433: parsing XML with a non-default encoding and
633 a CharacterDataHandler could crash the interpreter in pyexpat.
634
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000635- Patch #1516912: improve Modules support for OpenVMS.

638-----
639
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000640- Automate Windows build process for the Win64 SSL module.
641
Tim Peters32a83612006-07-10 21:08:24 +0000642- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000643 Previously, the slight difference could cause compilation errors of the
644 'zlib' module on systems with more than one version of zlib.
645
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000646- The MSI compileall step was fixed to also support a TARGETDIR
647 with spaces in it.
648
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000649- Bug #1517388: sqlite3.dll is now installed on Windows independent
650 of Tcl/Tk.
651
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000652- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000653 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +0000655Tests
656-----
657
658- Call os.waitpid() at the end of tests that spawn child processes in order
659 to minimize resources (zombies).
660
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000661Documentation
662-------------
663
Nick Coghlan2d792252006-07-06 13:47:18 +0000664- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
665 documentation for the warnings module.
666
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000667- Patch #1509163: MS Toolkit Compiler no longer available.
668
Neal Norwitz56640df2006-07-10 02:36:41 +0000669- Patch #1504046: Add documentation for xml.etree.

Nick Coghlanc649ec52006-05-29 12:43:05 +0000672What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +0000673================================
Anthony Baxter51bcb682006-04-05 14:51:42 +0000674
Anthony Baxterd1136802006-06-19 12:04:15 +0000675*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000676
677Core and builtins
678-----------------
679
Georg Brandla56b9152006-06-19 06:35:54 +0000680- Patch #1507676: Error messages returned by invalid abstract object operations
681 (such as iterating over an integer) have been improved and now include the
682 type of the offending object to help with debugging.
683
Brett Cannonea3912b2006-06-13 21:46:41 +0000684- Bug #992017: A classic class that defined a __coerce__() method that returned
685 its arguments swapped would infinitely recurse and segfault the interpreter.
686
Neal Norwitz909eb122006-06-12 02:13:21 +0000687- Fix the socket tests so they can be run concurrently.
688
Neal Norwitzb9845e72006-06-12 02:11:18 +0000689- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000690 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000691
Brett Cannon22565aa2006-06-09 22:31:23 +0000692- Bug #532646: object.__call__() will continue looking for the __call__
693 attribute on objects until one without one is found. This leads to recursion
694 when you take a class and set its __call__ attribute to an instance of the
695 class. Originally fixed for classic classes, but this fix is for new-style.
696 Removes the infinite_rec_3 crasher.
697
Georg Brandl24250812006-06-09 18:45:48 +0000698- The string and unicode methods startswith() and endswith() now accept
699 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
700
Brett Cannonde3b0522006-06-08 17:00:45 +0000701- Buffer objects, at the C level, never used the char buffer
702 implementation even when the char buffer for the wrapped object was
703 explicitly requested (originally returned the read or write buffer).
704 Now a TypeError is raised if the char buffer is not present but is
705 requested.
706
Georg Brandlddbaa662006-06-04 21:56:52 +0000707- Patch #1346214: Statements like "if 0: suite" are now again optimized
708 away like they were in Python 2.4.
709
Georg Brandlb7c8f542006-05-27 12:30:25 +0000710- Builtin exceptions are now full-blown new-style classes instead of
711 instances pretending to be classes, which speeds up exception handling
712 by about 80% in comparison to 2.5a2.
713
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000714- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
715 Unicode 4.1.
716
Georg Brandlf4ef1162006-05-26 18:03:31 +0000717- Patch #921466: sys.path_importer_cache is now used to cache valid and
718 invalid file paths for the built-in import machinery which leads to
719 fewer open calls on startup.
720
Tim Peters696cf432006-05-24 21:10:40 +0000721- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
722 of-2 bases. The largest speedup is for inputs with about 1000 decimal
723 digits. Conversion from non-power-of-2 bases remains quadratic-time in
724 the number of input digits (it was and remains linear-time for bases
725 2, 4, 8, 16 and 32).
726
Tim Petersb713ec22006-05-23 18:45:30 +0000727- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
728 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
729 an integer close to ``sys.maxint``. This was repaired by patch
730 #1335972, which also gives a nice speedup.
731
Richard Jonescebbefc2006-05-23 18:28:17 +0000732- Patch #1337051: reduced size of frame objects.
733
734- PyErr_NewException now accepts a tuple of base classes as its
735 "base" parameter.
736
Richard Jones7c88dcc2006-05-23 10:37:38 +0000737- Patch #876206: function call speedup by retaining allocated frame
738 objects.
739
Georg Brandl7b90e162006-05-18 07:01:27 +0000740- Bug #1462152: file() now checks more thoroughly for invalid mode
741 strings and removes a possible "U" before passing the mode to the
742 C library function.
743
Neal Norwitz1004a532006-05-15 07:17:23 +0000744- Patch #1488312, Fix memory alignment problem on SPARC in unicode
745
Neal Norwitz373f0a72006-05-15 07:04:36 +0000746- Bug #1487966: Fix SystemError with conditional expression in assignment
747
Martin v. Löwis879768d2006-05-11 13:28:43 +0000748- WindowsError now has two error code attributes: errno, which carries
749 the error values from errno.h, and winerror, which carries the error
750 values from winerror.h. Previous versions put the winerror.h values
751 (from GetLastError()) into the errno attribute.
752
Martin v. Löwis77736712006-05-04 05:51:03 +0000753- Patch #1475845: Raise IndentationError for unexpected indent.
754
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000755- Patch #1479181: split open() and file() from being aliases for each other.
756
Tim Peters44bd9862006-06-01 13:49:23 +0000757- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
758 methods were always silently ignored by dictionaries when comparing keys.
759 They are now passed through (except when using the C API function
760 ``PyDict_GetItem()``, whose semantics did not change).
761
762- Bug #1456209: In some obscure cases it was possible for a class with a
763 custom ``__eq__()`` method to confuse dict internals when class instances
764 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
765 No, you don't have any code that did this ;-)

771
772- Patch #1462338: Upgrade pyexpat to expat 2.0.0
773
Brett Cannon6ee7d012006-06-08 16:23:04 +0000774- Change binascii.hexlify to accept a read-only buffer instead of only a char
775 buffer and actually follow its documentation.
776
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000777- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
778
Nick Coghlanc649ec52006-05-29 12:43:05 +0000779- Patch #1478788 (modified version): The functional extension module has
780 been renamed to _functools and a functools Python wrapper module added.
781 This provides a home for additional function related utilities that are
782 not specifically about functional programming. See PEP 309.
783
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000784- Patch #1493701: performance enhancements for struct module.
785
Georg Brandl378d5922006-05-17 14:26:50 +0000786- Patch #1490224: time.altzone is now set correctly on Cygwin.
787
Georg Brandl8d3342b2006-05-16 07:38:27 +0000788- Patch #1435422: zlib's compress and decompress objects now have a
789 copy() method.
790
Andrew MacIntyre92913322006-06-13 15:04:24 +0000791- Patch #1454481: thread stack size is now tunable at runtime for thread
792 enabled builds on Windows and systems with Posix threads support.
793
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000794- On Win32, os.listdir now supports arbitrarily-long Unicode path names
795 (up to the system limit of 32K characters).
796
797- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
798 As a result, these functions now raise WindowsError instead of OSError.
799
Tim Peters7a822da2006-05-25 21:50:17 +0000800- ``time.clock()`` on Win64 should use the high-performance Windows
801 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
802 Windows platforms).
803
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000804- Calling Tk_Init twice is refused if the first call failed as that
805 may deadlock.
806
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000807- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
808 accept it without potentially using an uninitialized pointer.
809
810- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
811 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
812 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000813
Gregory P. Smith372b5832006-06-05 18:48:21 +0000814- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000815 [pybsddb project SF patch number 1466734]
816
Gregory P. Smith372b5832006-06-05 18:48:21 +0000817- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
818 parameter is supplied. [SF pybsddb bug #1477863]
819
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000820- bsddb: the __len__ method of a DB object has been fixed to return correct
821 results. It could previously incorrectly return 0 in some cases.
822 Fixes SF bug 1493322 (pybsddb bug 1184012).
823
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000824- bsddb: the bsddb.dbtables Modify method now raises the proper error and
825 aborts the db transaction safely when a modifier callback fails.
826 Fixes SF python patch/bug #1408584.
827
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000828- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000829 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000830 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
831 database calls that would previously deadlock. [SF python bug #775414]
832
Vinay Sajip28e57612006-07-01 10:45:20 +0000833- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000834
Walter Dörwald4994d952006-06-19 08:07:50 +0000835- Patch #1506645: add Python wrappers for the curses functions
836 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000837
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000838Library
839-------
840
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000841- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
842 functions.
843
Martin v. Löwis3798da02006-06-17 18:44:27 +0000844- Patch #812986: Update turtle output even if not tracing.
845
Vinay Sajip28e57612006-07-01 10:45:20 +0000846- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000847 Tkinter.BaseWidget.
848
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000849- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
850
Martin v. Löwis337487e2006-06-17 09:15:14 +0000851- Patch #763580: Add name and value arguments to Tkinter variable
852 classes.
853
Georg Brandl83cc0d02006-06-14 08:50:03 +0000854- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
855 mime.types file for determining MIME types.
856
Georg Brandl2605ca82006-06-14 06:08:31 +0000857- Bug #1339007: Shelf objects now don't raise an exception in their
858 __del__ method when initialization failed.
859
Martin v. Löwisd8251432006-06-14 05:21:04 +0000860- Patch #1455898: The MBCS codec now supports the incremental mode for
861 double-byte encodings.
862
Tim Peters43898b42006-06-14 04:09:25 +0000863- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
864 guarantee that adjacent triples in the return list always describe
865 non-adjacent blocks. Previously, a pair of matching blocks could end
866 up being described by multiple adjacent triples that formed a partition
867 of the matching pair.
868
Greg Ward0e0c9f42006-06-11 16:24:11 +0000869- Bug #1498146: fix optparse to handle Unicode strings in option help,
870 description, and epilog.
871
Greg Wardd1c797e2006-06-11 14:42:41 +0000872- Bug #1366250: minor optparse documentation error.
873
Greg Ward7f547402006-06-11 00:40:49 +0000874- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
875 clarify docs.
876
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000877- The wsgiref package has been added to the standard library.
878
Nick Coghlan676725d2006-06-08 13:54:49 +0000879- The functions update_wrapper() and wraps() have been added to the functools
880 module. These make it easier to copy relevant metadata from the original
881 function when writing wrapper functions.
882
Tim Petersd6a9eef2006-06-05 01:48:21 +0000883- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
884 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000885
Martin v. Löwis3f767792006-06-04 19:36:28 +0000886- Patch #1359618: Speed up charmap encoder by using a trie structure
887 for lookup.
888
Tim Petersd609b1a2006-06-02 23:22:51 +0000889- The functions in the ``pprint`` module now sort dictionaries by key
890 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
891 if and only if its display required more than one line, although that
892 wasn't documented. The new behavior increases predictability; e.g.,
893 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
894
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000895- Patch #1497027: try HTTP digest auth before basic auth in urllib2
896 (thanks for J. J. Lee).
897
Georg Brandl2b330372006-05-28 20:23:12 +0000898- Patch #1496206: improve urllib2 handling of passwords with respect to
899 default HTTP and HTTPS ports.
900
George Yoshidaf3c65de2006-05-28 16:39:09 +0000901- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
902
Bob Ippolito7298f272006-05-23 18:43:47 +0000903- Patch #1281707: speed up gzip.readline.
904
Georg Brandlb89316f2006-05-17 15:51:16 +0000905- Patch #1180296: Two new functions were added to the locale module:
906 format_string() to get the effect of "format % items" but locale-aware,
907 and currency() to format a monetary number with currency sign.
908
Georg Brandle3a25832006-05-17 14:56:04 +0000909- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
910 and several features added, such as speed and geometry control.
911
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000912- Patch #1488881: add support for external file objects in bz2 compressed
913 tarfiles.
914
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000915- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
916 stdout arguments, making it possible to redirect input and output
917 for remote debugging.
918
919- Patch #1484695: Update the tarfile module to version 0.8. This fixes
920 a couple of issues, notably handling of long file names using the
921 GNU LONGNAME extension.
922
923- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
924 new flag when ``name`` is already the name of an option flag.
925
926- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
927 package.
928
929- Patch #1472854: make the rlcompleter.Completer class usable on non-
930 UNIX platforms.
931
932- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
933
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000934- Bug #1472827: correctly escape newlines and tabs in attribute values in
935 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000965What's New in Python 2.5 alpha 2?
966=================================
967
968*Release date: 27-APR-2006*
969
970Core and builtins
971-----------------
972
Thomas Heller1b046642006-04-18 18:51:06 +0000973- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
974 by converting these apis from macros into exported functions again:
975
976 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
977 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
978 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
979 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
980 PyRun_String Py_CompileString
981
Martin v. Löwis45294a92006-04-18 06:24:08 +0000982- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
983
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000984- All uses of PyStructSequence_InitType have been changed to initialize
985 the type objects only once, even if the interpreter is initialized
986 multiple times.
987
Neal Norwitz61546162006-04-14 05:20:28 +0000988- Bug #1454485, array.array('u') could crash the interpreter. This was
989 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
990 to unicode when it didn't make sense. 'u#' now requires a unicode string.
991
992- Py_UNICODE is unsigned. It was always documented as unsigned, but
993 due to a bug had a signed value in previous versions.
994
Tim Peters3a5e8b12006-04-11 01:44:07 +0000995- Patch #837242: ``id()`` of any Python object always gives a positive
996 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
997 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000998 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000999 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001000
Tim Peters3a5e8b12006-04-11 01:44:07 +00001001 def __hash__(self):
1002 return id(self) # WRONG
1003
1004 because a hash result must be a (short) Python int but it was always
1005 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001006 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001007 was always usable as a hash value before this patch. That's no longer
1008 necessarily so.
1009
1010- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001011 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001012 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001013 #1454844)
1014
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001015- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1016 involving generators that have paused outside of any ``try`` or ``with``
1017 blocks. (In 2.5a1, a paused generator that was part of a reference
1018 cycle could not be garbage collected, regardless of whether it was
1019 paused in a ``try`` or ``with`` block.)

1023
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001024- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1025 is a macro.
1026
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001027- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1028 fails with an error condition.
1029
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001030- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1031
1032- Bug #1117761: bsddb.*open() no longer raises an exception when using
1033 the cachesize parameter.
1034
1035- Bug #1149413: bsddb.*open() no longer raises an exception when using
1036 a temporary db (file=None) with the 'n' flag to truncate on open.
1037
1038- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1039 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001040
Armin Rigoa9017c32006-04-19 11:50:27 +00001041- Patch #1062014: AF_UNIX sockets under Linux have a special
1042 abstract namespace that is now fully supported.
1043
Anthony Baxter51bcb682006-04-05 14:51:42 +00001044Library
1045-------
1046
Peter Astrand7d1d4362006-07-14 14:04:45 +00001047- Bug #1223937: subprocess.CalledProcessError reports the exit status
1048 of the process using the returncode attribute, instead of
1049 abusing errno.
1050
Tim Peters711bf302006-04-25 03:31:36 +00001051- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1052 a doctest to be skipped (the code is not run, and the expected output
1053 or exception is ignored).
1054
Nick Coghlanda2268f2006-04-24 04:37:15 +00001055- Fixed contextlib.nested to cope with exceptions being raised and
1056 caught inside exit handlers.
1057
Greg Wardab05edc2006-04-23 03:47:58 +00001058- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1059 hex, octal, or binary; add ``append_const`` action; keep going if
1060 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1061 added ``epilog`` for better help generation).
1062
Tim Peters21fbd572006-04-21 21:18:10 +00001063- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1064 called from a thread spawned as a side effect of importing a module.
1065
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001066- The pydoc module now supports documenting packages contained in
1067 .zip or .egg files.
1068
1069- The pkgutil module now has several new utility functions, such
1070 as ``walk_packages()`` to support working with packages that are either
1071 in the filesystem or zip files.
1072
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001073- The mailbox module can now modify and delete messages from
1074 mailboxes, in addition to simply reading them. Thanks to Gregory
1075 K. Johnson for writing the code, and to the 2005 Google Summer of
1076 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001077
Tim Petersc7605f22006-04-17 21:12:33 +00001078- The ``__del__`` method of class ``local`` in module ``_threading_local``
1079 returned before accomplishing any of its intended cleanup.
1080
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001081- Patch #790710: Add breakpoint command lists in pdb.
1082
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001083- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +00001085- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1086
Anthony Baxtere29002c2006-04-12 12:07:31 +00001087- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1088 Windows. Bug #1469163.
1089
Phillip J. Eby47032112006-04-11 01:07:43 +00001090- The warnings, linecache, inspect, traceback, site, and doctest modules
1091 were updated to work correctly with modules imported from zipfiles or
1092 via other PEP 302 __loader__ objects.
1093
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001094- Patch #1467770: Reduce usage of subprocess._active to processes which
1095 the application hasn't waited on.
1096
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001097- Patch #1462222: Fix Tix.Grid.
1098
Neal Norwitza31bf182006-04-09 03:35:43 +00001099- Fix exception when doing glob.glob('anything*/')
1100
Skip Montanaro262fb922006-04-21 02:31:07 +00001101- The pstats.Stats class accepts an optional stream keyword argument to
1102 direct output to an alternate file-like object.
1103

1105-----
1106
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001107- The Makefile now has a reindent target, which runs reindent.py on
1108 the library.
1109
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001110- Patch #1470875: Building Python with MS Free Compiler
1111
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001112- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001113
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001114- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1115 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001116 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001117 CXX from --with-cxx-main, see description in README.
1118
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001119- Patch #1429775: Link extension modules with the shared libpython.
1120
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001121- Fixed a libffi build problem on MIPS systems.
1122
Tim Peters8931ff12006-05-13 23:28:20 +00001123- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1124 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1125 and "%zu" for unsigned integers of type ``size_t``.
1126
Anthony Baxter51bcb682006-04-05 14:51:42 +00001127Tests
1128-----
1129
Nick Coghlanda2268f2006-04-24 04:37:15 +00001130- test_contextlib now checks contextlib.nested can cope with exceptions
1131 being raised and caught inside exit handlers.
1132
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001133- test_cmd_line now checks operation of the -m and -c command switches
1134
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001135- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1136 it separately and by hand. It also wasn't cleaning up its changes to
1137 the current Decimal context.
1138
Thomas Woutersabd08882006-04-26 15:53:30 +00001139- regrtest.py now has a -M option to run tests that test the new limits of
1140 containers, on 64-bit architectures. Running these tests is only sensible
1141 on 64-bit machines with more than two gigabytes of memory. The argument
1142 passed is the maximum amount of memory for the tests to use.

1151-------------
1152
Tim Petersb06d28c2006-05-12 01:57:59 +00001153- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1154
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001155- PEP 343: Added Context Types section to the library reference
1156 and attempted to bring other PEP 343 related documentation into
1157 line with the implementation and/or python-dev discussions.
1158
Tim Peters8dc73d22006-04-24 02:03:16 +00001159- Bug #1337990: clarified that ``doctest`` does not support examples
1160 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001163What's New in Python 2.5 alpha 1?
1164=================================
1165
Anthony Baxterebed3f62006-04-03 15:03:44 +00001166*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001167
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001168Core and builtins
1169-----------------
1170
Nick Coghlan43832302006-04-23 17:04:07 +00001171- PEP 338: -m command line switch now delegates to runpy.run_module
1172 allowing it to support modules in packages and zipfiles
1173
Martin v. Löwisc661b882006-04-20 04:54:23 +00001174- On Windows, .DLL is not an accepted file name extension for
1175 extension modules anymore; extensions are only found if they
1176 end in .PYD.
1177
Martin v. Löwisea62d252006-04-03 10:56:49 +00001178- Bug #1421664: sys.stderr.encoding is now set to the same value as
1179 sys.stdout.encoding.
1180
Neal Norwitz92e212f2006-04-03 04:48:37 +00001181- __import__ accepts keyword arguments.
1182
Georg Brandlccadf842006-03-31 18:54:53 +00001183- Patch #1460496: round() now accepts keyword arguments.
1184
Anthony Baxter262c00a2006-03-30 10:53:17 +00001185- Fixed bug #1459029 - unicode reprs were double-escaped.
1186
Hye-Shik Changd478f342006-03-23 12:32:36 +00001187- Patch #1396919: The system scope threads are reenabled on FreeBSD
1188 5.4 and later versions.
1189
Neal Norwitze98ccf62006-03-23 05:39:47 +00001190- Bug #1115379: Compiling a Unicode string with an encoding declaration
1191 now gives a SyntaxError.
1192
Georg Brandlabd1ff82006-03-18 07:59:59 +00001193- Previously, Python code had no easy way to access the contents of a
1194 cell object. Now, a ``cell_contents`` attribute has been added
1195 (closes patch #1170323).
1196
Tim Peterscf79aac2006-03-16 01:14:46 +00001197- Patch #1123430: Python's small-object allocator now returns an arena to
1198 the system ``free()`` when all memory within an arena becomes unused
1199 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1200 freed. Some applications will see a drop in virtual memory size now,
1201 especially long-running applications that, from time to time, temporarily
1202 use a large number of small objects. Note that when Python returns an
1203 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001204 platform C library will in turn return that memory to the operating system.
1205 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001206 appears to be effective at least on Microsoft C and gcc-based systems.
1207 Thanks to Evan Jones for hard work and patience.
1208
Georg Brandl533ff6f2006-03-08 18:09:27 +00001209- Patch #1434038: property() now uses the getter's docstring if there is
1210 no "doc" argument given. This makes it possible to legitimately use
1211 property() as a decorator to produce a read-only property.
1212
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001213- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1214 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1215 of requiring an int or long in slicing and a few other contexts, enabling
1216 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1217
Neal Norwitz995acdf2006-03-07 05:01:00 +00001218- Fixed various bugs reported by Coverity's Prevent tool.
1219
Brett Cannonbf364092006-03-01 04:25:17 +00001220- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1221 new exception base class, BaseException, which has a new message attribute.
1222 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1223 Raising a string exception now raises a DeprecationWarning.
1224
Thomas Woutersfb609f42006-02-28 16:37:25 +00001225- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1226 explicitly relative, using 'from .module import name' to mean 'from the same
1227 package as this module is in. Imports without dots still default to the
1228 old relative-then-absolute, unless 'from __future__ import
1229 absolute_import' is used.
1230
Brett Cannona7446e32006-02-27 23:39:10 +00001231- Properly check if 'warnings' raises an exception (usually when a filter set
1232 to "error" is triggered) when raising a warning for raising string
1233 exceptions.
1234
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001235- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001236 The name was removed from Include/code.h.
1237
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001238- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001239
Guido van Rossum1968ad32006-02-25 22:38:04 +00001240- Patch 1433928:
1241 - The copy module now "copies" function objects (as atomic objects).
1242 - dict.__getitem__ now looks for a __missing__ hook before raising
1243 KeyError.
1244
Tim Peters84ef21c2006-02-28 20:39:06 +00001245- PEP 343: with statement implemented. Needs ``from __future__ import
1246 with_statement``. Use of 'with' as a variable will generate a warning.
1247 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001248 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001249 The following objects have __context__ methods:
1250 - The built-in file type.
1251 - The thread.LockType type.
1252 - The following types defined by the threading module:
1253 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1254 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001255
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001256- Fix the encodings package codec search function to only search
1257 inside its own package. Fixes problem reported in patch #1433198.
1258
1259 Note: Codec packages should implement and register their own
1260 codec search function. PEP 100 has the details.
1261
Tim Peters9ea89d22006-06-04 03:26:02 +00001262- PEP 353: Using ``Py_ssize_t`` as the index type.
1263
1264- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1265 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1266 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1267 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1268 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001269
Neal Norwitzfc76d632006-01-10 06:03:13 +00001270- Patch #1400181, fix unicode string formatting to not use the locale.
1271 This is how string objects work. u'%f' could use , instead of .
1272 for the decimal point. Now both strings and unicode always use periods.
1273
Neal Norwitz671b9e32006-01-09 07:07:12 +00001274- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1275 configure would break checking curses.h.
1276
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001277- Bug #959576: The pwd module is now builtin. This allows Python to be
1278 built on UNIX platforms without $HOME set.
1279
Neal Norwitzc10978f2005-12-19 06:07:16 +00001280- Bug #1072182, fix some potential problems if characters are signed.
1281
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001282- Bug #889500, fix line number on SyntaxWarning for global declarations.
1283
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001284- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1285
Neal Norwitze7214a12005-12-18 05:03:17 +00001286- Support for converting hex strings to floats no longer works.
1287 This was not portable. float('0x3') now raises a ValueError.
1288
Barry Warsaw2a38a862005-12-18 01:27:35 +00001289- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001290 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001291 is now displayed in interactive prompt banner.
1292
Georg Brandlfa166682005-12-17 21:45:17 +00001293- Implementation of PEP 341 - Unification of try/except and try/finally.
1294 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001295 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001296
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001297- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1298 now encodes backslash correctly.
1299
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001300- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1301
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001302- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001303 and long longs.
1304
Neal Norwitz67715f02005-11-09 06:59:35 +00001305- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001306 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001307 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001308
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001309- Replaced most Unicode charmap codecs with new ones using the
1310 new Unicode translate string feature in the builtin charmap
1311 codec; the codecs were created from the mapping tables available
1312 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1313 encodings now include a mapping for the Apple logo)
1314
Tim Peterse3547fd2005-12-16 23:13:57 +00001315- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001316
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001317- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001318
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001319- A new AST parser implementation was completed. The abstract
1320 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001321 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001322
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001323- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001324 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1325
Neal Norwitz708e51a2005-10-03 04:48:15 +00001326- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1327
Neal Norwitz11bd1192005-10-03 00:54:56 +00001328- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1329 Provide a warning when a directory is passed on the command line.
1330
Neal Norwitz40d37812005-10-02 01:48:49 +00001331- Fix segfault with invalid coding.
1332
1333- SF bug #772896: unknown encoding results in MemoryError.
1334
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001335- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001336 supported a __len__() method which evaluated to False when the iterator
1337 was empty.
1338
Guido van Rossum630db602005-09-20 18:49:54 +00001339- On 64-bit platforms, when __len__() returns a value that cannot be
1340 represented as a C int, raise OverflowError.
1341
Skip Montanarof8948ca2005-09-19 03:54:46 +00001342- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001343 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001344
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001345- SF bug #893549: parsing keyword arguments was broken with a few format
1346 codes.
1347
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001348- Changes donated by Elemental Security to make it work on AIX 5.3
1349 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1350 bug #105470: test_pwd fails on 64bit system (Opteron).
1351
Guido van Rossum539c6622005-09-14 17:49:54 +00001352- Changes donated by Elemental Security to make it work on HP-UX 11 on
1353 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1354
Georg Brandl4550b8d2005-08-26 06:43:52 +00001355- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001356 (fixes bug #1119418).
1357
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001358- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1359
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001360- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1361 exceptions that cause a function to exit.
1362
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001363- The implementation of set() and frozenset() was revised to use its
1364 own internal data structure. Memory consumption is reduced by 1/3
1365 and there are modest speed-ups as well. The API is unchanged.
1366
Tim Petersde7990b2005-07-17 23:45:23 +00001367- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1368
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001369- SF bug #1229429: PyObject_CallMethod failed to decrement some
1370 reference counts in some error exit cases.
1371
Tim Petersecc6e6a2005-07-10 22:30:55 +00001372- SF bug #1185883: Python's small-object memory allocator took over
1373 a block managed by the platform C library whenever a realloc specified
1374 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001375 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001376 portable way to copy data from the C-managed block into Python's
1377 small-object space without risking a memory fault. Python's small-object
1378 realloc now leaves such blocks under the control of the platform C
1379 realloc.
1380
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001381- SF bug #1232517: An overflow error was not detected properly when
1382 attempting to convert a large float to an int in os.utime().
1383
Raymond Hettinger3296e692005-06-29 23:29:56 +00001384- SF bug #1224347: hex longs now print with lowercase letters just
1385 like their int counterparts.
1386
Michael W. Hudson188d4362005-06-20 16:52:57 +00001387- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1388 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1389 interpreter states; back out that fix and do a better job (see
1390 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1391 for a longer write-up of the problem).
1392
Michael W. Hudsondf888462005-06-03 14:41:55 +00001393- SF patch #1180995: marshal now uses a binary format by default when
1394 serializing floats.
1395
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001396- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1397 the routines that promise to produce IEEE 754 binary representations
1398 of floats now simply copy bytes around.
1399
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001400- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1401 278.
1402
Brett Cannonc3647ac2005-04-26 03:45:26 +00001403- patch #1109424: int, long, float, complex, and unicode now check for the
1404 proper magic slot for type conversions when subclassed. Previously the
1405 magic slot was ignored during conversion. Semantics now match the way
1406 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001407 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001408 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001409 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001410
Barry Warsawc8d907c2005-04-19 23:43:40 +00001411- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1412 NULL, now raise an AttributeError when attempting to set or delete the
1413 attribute. Previously a TypeError was raised, but this was inconsistent
1414 with the equivalent pure-Python implementation.
1415
Michael W. Hudson774479c2005-04-18 08:46:17 +00001416- It is now safe to call PyGILState_Release() before
1417 PyEval_InitThreads() (note that if there is reason to believe there
1418 are multiple threads around you still must call PyEval_InitThreads()
1419 before using the Python API; this fix is for extension modules that
1420 have no way of knowing if Python is multi-threaded yet).
1421
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001422- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1423 disabled caused a crash.
1424
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001425- Bug #1165306: instancemethod_new allowed the creation of a method
1426 with im_class == im_self == NULL, which caused a crash when called.
1427
Tim Petersecc6e6a2005-07-10 22:30:55 +00001428- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001429 fixes the crash seen in bug #1165761
1430
Raymond Hettinger96229b12005-03-11 06:49:40 +00001431- Added two new builtins, any() and all().
1432
Brett Cannon409d8f22005-03-05 06:47:57 +00001433- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001434 (e.g., ``class C(): pass`` is no longer a syntax error).
1435 Patch #1176012 added support to the 'parser' module and 'compiler' package
1436 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001437
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001438- Patch #1115086: Support PY_LONGLONG in structmember.
1439
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001440- Bug #1155938: new style classes did not check that __init__() was
1441 returning None.
1442
Tim Petersecc6e6a2005-07-10 22:30:55 +00001443- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001444 ('\') with a specific error message.
1445
Martin v. Löwisff232d72005-03-03 09:24:38 +00001446- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1447
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001448- Bug #1124295: the __name__ attribute of file objects was
1449 inadvertently made inaccessible in restricted mode.
1450
Tim Petersecc6e6a2005-07-10 22:30:55 +00001451- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001452 an ferror() call.
1453
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001454- min() and max() now support key= arguments with the same meaning as in
1455 list.sort().
1456
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001457- The peephole optimizer now performs simple constant folding in expressions:
1458 (2+3) --> (5).
1459
Raymond Hettingera422c342005-01-11 03:03:27 +00001460- set and frozenset objects can now be marshalled. SF #1098985.
1461
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001462- Bug #1077106: Poor argument checking could cause memory corruption
1463 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001464
Jeremy Hyltonab630502005-02-04 18:44:06 +00001465- The parser did not complain about future statements in illegal
1466 positions. It once again reports a syntax error if a future
1467 statement occurs after anything other than a doc string.
1468
Neil Schemenauercf52c072005-08-12 17:34:58 +00001469- Change the %s format specifier for str objects so that it returns a
1470 unicode instance if the argument is not an instance of basestring and
1471 calling __str__ on the argument returns a unicode instance.
1472
Tim Petersf4e69282006-02-27 17:15:31 +00001473- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1474 current thread state when the auto-GIL-state machinery knows about
1475 it (since the thread state is being deleted, continuing to remember it
1476 can't help, but can hurt if another thread happens to get created with
1477 the same thread id).
1478
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001479Extension Modules
1480-----------------
1481
Georg Brandl43f08a82006-03-31 18:01:16 +00001482- Patch #1380952: fix SSL objects timing out on consecutive read()s
1483
Neal Norwitz05a45592006-03-20 06:30:08 +00001484- Patch #1309579: wait3 and wait4 were added to the posix module.
1485
Anthony Baxterfa869072006-03-20 05:21:58 +00001486- Patch #1231053: The audioop module now supports encoding/decoding of alaw.

1655
Raymond Hettingerb2594052004-12-05 09:25:51 +00001656- itertools.islice() now accepts None for the start and step arguments.
1657 This allows islice() to work more readily with slices:
1658 islice(s.start, s.stop, s.step)
1659
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001660- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001669- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1670 been renamed to have only a single underscore prefix. This was done to
1671 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001672
Nick Coghlan43832302006-04-23 17:04:07 +00001673- PEP 338: new module runpy defines a run_module function to support
1674 executing modules which provide access to source code or a code object
1675 via the PEP 302 import mechanisms.
1676
Anthony Baxter93f5b932006-04-03 08:05:07 +00001677- The email module's parsedate_tz function now sets the daylight savings

1685 in attribute values.
1686
Anthony Baxterc51ee692006-04-01 00:57:31 +00001687- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001688 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001689 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001690 module will not be built.
1691
Tim Petersc17976e2006-04-01 00:26:53 +00001692- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1693 aren't officially supported here, and trying to use them will probably
1694 raise an exception some day. But dicts have been allowed, and "mostly
1695 worked", so support for them won't go away without warning.
1696
Georg Brandl338ef7d2006-03-31 18:42:16 +00001697- Bug #1445068: getpass.getpass() can now be given an explicit stream
1698 argument to specify where to write the prompt.
1699

1715
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001716- email 4.0 package now integrated. This is largely the same as the email 3.0
1717 package that was included in Python 2.3, except that PEP 8 module names are
1718 now used (e.g. mail.message instead of email.Message). The MIME classes
1719 have been moved to a subpackage (e.g. email.mime.text instead of
1720 email.MIMEText). The old names are still supported for now. Several
1721 deprecated Message methods have been removed and lots of bugs have been
1722 fixed. More details can be found in the email package documentation.
1723
Walter Dörwald40108c92006-03-27 08:15:44 +00001724- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1725 (a subclass of tuple) that provides incremental decoders and encoders
1726 (a way to use stateful codecs without the stream API). Python functions
1727 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1728 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1729 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001731- Patch #1359365: Calling next() on a closed StringIO.String object raises
1732 a ValueError instead of a StopIteration now (like file and cString.String do).
1733 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1734 called before (like file and StringIO.StringIO do).

1810 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1811 Ronald L. Rivest offered this advice for Python:
1812
1813 "The consensus of researchers in this area (at least as
1814 expressed at the NIST Hash Function Workshop 10/31/05),
1815 is that SHA-256 is a good choice for the time being, but
1816 that research should continue, and other alternatives may
1817 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001818

1999 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002000 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002001 PEP 305.

2005 dictates.
2006 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002007 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002008 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002009 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2010 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002011 + reader now allows \r characters to be quoted (previously it only allowed
2012 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002013 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002014 + Dialect classes passed to the module are no longer instantiated by
2015 the module before being parsed (the former validation scheme required
2016 this, but the mechanism was unreliable).
2017 + The dialect registry now contains instances of the internal
2018 C-coded dialect type, rather than references to python objects.
2019 + the internal c-coded dialect type is now immutable.
2020 + register_dialect now accepts the same keyword dialect specifications
2021 as the reader and writer, allowing the user to register dialects
2022 without first creating a dialect class.
2023 + a configurable limit to the size of parsed fields has been added -
2024 previously, an unmatched quote character could result in the entire
2025 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002026 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002027 the parser field size limit (returning the former limit). The initial
2028 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002029 + A line_num attribute has been added to the reader object, which tracks
2030 the number of lines read from the source iterator. This is not
2031 the same as the number of records returned, as records can span
2032 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002033 + reader and writer objects were not being registered with the cyclic-GC.
2034 This has been fixed.
2035
Brett Cannone6539c42005-01-08 02:43:53 +00002036- _DummyThread objects in the threading module now delete self.__block that is
2037 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2038 lock primitives tend to be limited in number and thus should not be wasted on
2039 a _DummyThread object. Fixes bug #1089632.
2040
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002041- The imghdr module now detects Exif files.
2042
Raymond Hettinger6065d322004-12-20 23:51:53 +00002043- StringIO.truncate() now correctly adjusts the size attribute.
2044 (Bug #951915).
2045
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002046- locale.py now uses an updated locale alias table (built using
2047 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2048 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002049 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002050
Raymond Hettinger3557f422004-12-07 12:02:02 +00002051- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2052
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002053- the pickle module no longer accepts the deprecated None option in the
2054 args tuple returned by __reduce__().
2055
Brett Cannon84667c02004-12-07 03:25:18 +00002056- optparse now optionally imports gettext. This allows its use in setup.py.
2057
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002058- the pickle module no longer uses the deprecated bin parameter.
2059
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002060- the shelve module no longer uses the deprecated binary parameter.
2061

2063
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002064- the filecmp module no longer uses the deprecated use_statcache argument.
2065
Raymond Hettinger664347b2004-12-04 21:21:53 +00002066- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2067 extended or overridden by subclasses. Formerly, the subclassed method would
2068 be ignored by the rest of the module. (Bug #1078905).
2069
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002070- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002071 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002072
Walter Dörwald36733692004-12-22 12:50:50 +00002073- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2074 once when a size argument is given. This prevents a buffer overflow in the
2075 tokenizer with very long source lines.
2076
Barry Warsaw538561e2006-01-01 21:48:54 +00002077- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2078 immediately after creating the object, without any intervening
2079 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002080
Skip Montanaro05885812005-01-16 20:48:27 +00002081- The reconvert.quote function can now emit triple-quoted strings. The
2082 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002083
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002084- ``UserString.MutableString`` now supports negative indices in
2085 ``__setitem__`` and ``__delitem__``
2086
Greg Ward40407942005-03-05 02:53:17 +00002087- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2088 correctly.
2089
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002090- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2091 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2092 character even if the user has passed a size parameter to get a proper
2093 line ending. Remove the special handling of a "\r\n" that has been split
2094 between two lines.
2095
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002096- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2097 about illegal code points. The codec now supports PEP 293 style error
2098 handlers.
2099
Walter Dörwald78a78b02005-09-01 12:04:29 +00002100- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002101 from the input stream, so that the output is a byte string in the correct
2102 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002103
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002104- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2105 considering it exactly like a '*'.
2106
Walter Dörwald007f8df2005-10-09 19:42:27 +00002107- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2108 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002109
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002110- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2111
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002112- Patch #1413711: Certain patterns of differences were making difflib
2113 touch the recursion limit.
2114
Walter Dörwald58917a62006-03-31 15:26:22 +00002115- Bug #947906: An object oriented interface has been added to the calendar
2116 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002117 called as a script (e.g. via ``python -mcalendar``). Localized month and
2118 weekday names can be ouput (even if an exotic encoding is used) using
2119 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002120

2122-----
2123
Neal Norwitz602d3392006-03-31 08:21:40 +00002124- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2125 by using -mieee gcc option.
2126
Martin v. Löwis86d66262006-02-17 08:40:11 +00002127- Patch #1432345: Make python compile on DragonFly.
2128
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002129- Build support for Win64-AMD64 was added.
2130
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002131- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2132
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002133- Patch #881820: look for openpty and forkpty also in libbsd.
2134
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002135- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2136 The zlib module is now builtin on Windows.
2137
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002138- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2139
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002140- Bug #1189330: configure did not correctly determine the necessary
2141 value of LINKCC if python was built with GCC 4.0.
2142
Trent Mick8321b422005-07-26 02:29:21 +00002143- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2144 vulnerability in zlib 1.2.1 and 1.2.2.
2145
Brett Cannon08cd5982005-04-24 22:26:38 +00002146- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2147 flags that change binary compatibility. Changes were also made to
2148 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002149 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002150
Bob Ippolitoed233462005-03-29 13:47:59 +00002151- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2152 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2153 no longer exists). This configure patch makes things right.
2154
Martin v. Löwise2713be2005-03-08 15:03:08 +00002155- Bug #1158607: Build with --disable-unicode again.
2156
Brett Cannon46d96232005-02-16 00:07:19 +00002157- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2158 defined. Discovered as a result of not being able to build on OS X.
2159
Brett Cannon516592f2004-12-07 00:42:59 +00002160- setup.py now uses the directories specified in LDFLAGS using the -L option
2161 and in CPPFLAGS using the -I option for adding library and include
2162 directories, respectively, for compiling extension modules against. This has
2163 led to the core being compiled using the values in CPPFLAGS. It also removes
2164 the need for the special-casing of both DarwinPorts and Fink for darwin since
2165 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2166 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2167 Fink, ``-I/opt/local/include`` for DarwinPorts).
2168
Brett Cannon43802422005-02-10 20:48:03 +00002169- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2170 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2171 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2172 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002174C API
2175-----
2176
Tim Petersc9d78aa2006-03-26 23:27:58 +00002177- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2178 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2179 is obtained via the ``PyObject_`` family, it must be released via the
2180 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2181 always been officially true, but when Python's small-object allocator was
2182 introduced, an attempt was made to cater to a few extension modules
2183 discovered at the time that obtained memory via ``PyObject_New`` but
2184 released it via ``PyMem_DEL``. It's years later, and if such code still
2185 exists it will fail now (probably with segfaults, but calling wrong
2186 low-level memory management functions can yield many symptoms).
2187
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002188- Added a C API for set and frozenset objects.
2189
Raymond Hettinger66517482004-12-03 11:45:13 +00002190- Removed PyRange_New().
2191
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002192- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2193 mapping argument now. This string is used as a mapping table. Byte values
2194 greater than the length of the string and 0xFFFE are treated as undefined
2195 mappings.
