Guido van Rossumc69ac252006-08-10 18:09:25 +00007What's New in Python 2.5 release candidate 1?
8=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +00009
Guido van Rossum133f4e42006-08-10 17:42:50 +000010*Release date: 18-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +000011
12Core and builtins
13-----------------
14
Marc-André Lemburg040f76b2006-08-14 10:55:19 +000015- Unicode objects will no longer raise an exception when being
16 compared equal or unequal to a string and causing a
17 UnicodeDecodeError exception, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +000018
Marc-André Lemburg040f76b2006-08-14 10:55:19 +000019 Instead, the equal (==) and unequal (!=) comparison operators will
20 now issue a UnicodeWarning and interpret the two objects as
21 unequal. The UnicodeWarning can be filtered as desired using
22 the warning framework, e.g. silenced completely, turned into an
23 exception, logged, etc.
24
25 Note that compare operators other than equal and unequal will still
26 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +000027
Marc-André Lemburg757ea272006-08-14 11:44:34 +000028- Fix segfault when doing string formatting on subclasses of long.
29
30- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
31 with new-style classes.
32
33- Fix bug related to __len__ functions returning negative values with
34 classic classes.
35
36- Patch #1538606, Fix __index__() clipping. There were some problems
37 discovered with the API and how integers that didn't fit into Py_ssize_t
38 were handled. This patch attempts to provide enough alternatives
39 to effectively use __index__.
40
Martin v. Löwisab2f8f72006-08-09 07:57:39 +000041- Bug #1536021: __hash__ may now return long int; the final hash
42 value is obtained by invoking hash on the long int.
43
Thomas Hellerab1049c2006-08-08 17:37:00 +000044- Bug #1536786: buffer comparison could emit a RuntimeWarning.
45
Georg Brandl7e3ba2a2006-08-06 08:23:54 +000046- Bug #1535165: fixed a segfault in input() and raw_input() when
47 sys.stdin is closed.
48
Thomas Heller74d36f02006-08-04 18:17:40 +000049- On Windows, the PyErr_Warn function is now exported from
50 the Python dll again.
51
Neal Norwitz4ffedad2006-08-04 04:58:47 +000052- Bug #1191458: tracing over for loops now produces a line event
53 on each iteration. Fixing this problem required changing the .pyc
54 magic number. This means that .pyc files generated before 2.5c1
55 will be regenerated.
56
Neal Norwitz0cbd8052006-08-04 05:09:28 +000057- Bug #1333982: string/number constants were inappropriately stored
58 in the byte code and co_consts even if they were not used, ie
59 immediately popped off the stack.
60
Georg Brandle9462c72006-08-04 18:03:37 +000061- Fixed a reference-counting problem in property().
62
Neal Norwitzff4b63b2006-08-04 04:50:21 +000063
64Library
65-------
66
Neal Norwitzbf8c1952006-08-15 04:14:57 +000067- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
68
Georg Brandl7a1af772006-08-14 21:55:28 +000069- Patch #1536071: trace.py should now find the full module name of a
70 file correctly even on Windows.
71
Georg Brandl0a7d1bb2006-08-11 07:26:10 +000072- logging's atexit hook now runs even if the rest of the module has
73 already been cleaned up.
74
Guido van Rossum133f4e42006-08-10 17:42:50 +000075- Bug #1112549, DoS attack on cgi.FieldStorage.
76
Neal Norwitzff4b63b2006-08-04 04:50:21 +000077- Bug #1531405, format_exception no longer raises an exception if
78 str(exception) raised an exception.
79
Neil Schemenauer06ded092006-08-04 16:20:30 +000080- Fix a bug in the ``compiler`` package that caused invalid code to be
81 generated for nested functions.
82
Neal Norwitzff4b63b2006-08-04 04:50:21 +000083
84Extension Modules
85-----------------
86
Neal Norwitzbf8c1952006-08-15 04:14:57 +000087- Patch #1511317: don't crash on invalid hostname (alias) info.
88
Georg Brandl3335a7a2006-08-14 21:42:55 +000089- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
90 raises the correct exceptions.
91
Thomas Heller1ce433e2006-08-14 16:20:04 +000092- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
93 '-no-stack-protector' compiler flag for OpenBSD has been removed.
94
Thomas Heller86720042006-08-14 11:17:48 +000095- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
96 uses the _as_parameter_ attribute when objects are passed to foreign
97 function calls. The ctypes version number was changed to 1.0.1.
98
Bob Ippolitoe6c9f982006-08-04 23:59:21 +000099- Bug #1530559, struct.pack raises TypeError where it used to convert.
100 Passing float arguments to struct.pack when integers are expected
101 now triggers a DeprecationWarning.
102
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000103

110
Andrew MacIntyre16ee33a2006-08-06 12:37:03 +0000111- test_threading now skips testing alternate thread stack sizes on
112 platforms that don't support changing thread stack size.
113
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000114
Georg Brandl212b5872006-08-05 06:10:54 +0000115Documentation

Fred Drake53912162006-07-29 13:22:49 +0000144What's New in Python 2.5 beta 3?
145================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000146
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000147*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000148
149Core and builtins
150-----------------
151
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000152- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t, it previously
153 returned a long (see PEP 353).
154
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000155- Bug #1515471: string.replace() accepts character buffers again.
156
Neal Norwitz07aadb12006-07-30 06:55:48 +0000157- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
158 This provides the proper warning for struct.pack().
159 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
160
Neal Norwitz0d62a062006-07-30 06:53:31 +0000161- Patch #1531113: Fix augmented assignment with yield expressions.
162 Also fix a SystemError when trying to assign to yield expressions.
163
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000164- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
165 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
166 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
167 excessive filesystem operations during imports.
168
Tim Petersbc24eee2006-07-27 01:14:53 +0000169- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
170 operations on signed longs that are formally undefined by C.
171 Unfortunately, at least one compiler now cares about that, so complicated
172 the code to make that compiler happy again.
173
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000174- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
175
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000176- Patch #1232023: Stop including current directory in search
177 path on Windows.
178
Neal Norwitze1fdb322006-07-21 05:32:28 +0000179- Fix some potential crashes found with failmalloc.
180
Neal Norwitze7563102006-07-17 01:00:16 +0000181- Fix warnings reported by Klocwork's static analysis tool.
182
Neal Norwitz84be93b2006-07-16 01:50:38 +0000183- Bug #1512814, Fix incorrect lineno's when code within a function
184 had more than 255 blank lines.
185
Georg Brandl9dceedb2006-07-12 15:31:17 +0000186- Patch #1521179: Python now accepts the standard options ``--help`` and
187 ``--version`` as well as ``/?`` on Windows.
188
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000189- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000190 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000191 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000192
Tim Peters112aad32006-07-19 00:03:19 +0000193- Bug #1524317: Compiling Python ``--without-threads`` failed.
194 The Python core compiles again then, and, in a build without threads, the
195 new ``sys._current_frames()`` returns a dictionary with one entry,
196 mapping the faux "thread id" 0 to the current frame.
197
Ronald Oussoren3075e162006-07-25 20:28:55 +0000198- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000199
Ronald Oussoren3075e162006-07-25 20:28:55 +0000200
Neal Norwitza1f10902006-07-12 07:28:29 +0000201Library
202-------
203
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000204- Correction of patch #1455898: In the mbcs decoder, set final=False
205 for stream decoder, but final=True for the decode function.
206
Georg Brandl07fec3a2006-08-01 18:49:24 +0000207- os.urandom no longer masks unrelated exceptions like SystemExit or
208 KeyboardInterrupt.
209
Tim Peters4643c2f2006-08-10 22:45:34 +0000210- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000211 shutil.copytree on Windows
212
Georg Brandle34ac7c2006-07-30 11:07:23 +0000213- Bug #1002398: The documentation for os.path.sameopenfile now correctly
214 refers to file descriptors, not file objects.
215
Fred Drakefbdeaad2006-07-29 16:56:15 +0000216- Rename of the xml package to xmlcore, and the import hackery done to
217 make it appear at both names, has been removed. Bug #1511497,
218 #1513611, and probably others.
219
Georg Brandledd9b0d2006-07-29 09:33:26 +0000220- Bug #1441397: The compiler module now recognizes module and function
221 docstrings correctly as it did in Python 2.4.
222
Tim Peters6f681472006-07-27 23:44:37 +0000223- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
224 lost that tests are sorted by name before being run. This rarely
225 matters for well-written tests, but can create baffling symptoms if
226 side effects from one test to the next affect outcomes. ``DocTestFinder``
227 has been changed to sort the list of tests it returns.
228
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000229- The distutils version has been changed to 2.5.0, and are now kept
230 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000231
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000232- Bug #978833: Really close underlying socket in _socketobject.close.
233
Georg Brandl0619a322006-07-26 07:40:17 +0000234- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
235 with title().
236
Georg Brandlcf0c1722006-07-26 07:23:32 +0000237- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
238 to recursive calls and call it with the failing package name.
239
Martin v. Löwis0b483032006-07-25 09:53:12 +0000240- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
241
Georg Brandlc13c34c2006-07-24 14:09:56 +0000242- Patch #1515343: Fix printing of deprecated string exceptions with a
243 value in the traceback module.
244
Greg Ward48fae7a2006-07-23 16:05:51 +0000245- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
246
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000247- Patch #1524429: Use repr() instead of backticks in Tkinter again.
248
Brett Cannoncaebe222006-07-18 04:41:36 +0000249- Bug #1520914: Change time.strftime() to accept a zero for any position in its
250 argument tuple. For arguments where zero is illegal, the value is forced to
251 the minimum value that is correct. This is to support an undocumented but
252 common way people used to fill in inconsequential information in the time
253 tuple pre-2.4.
254
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000255- Patch #1220874: Update the binhex module for Mach-O.
256
Barry Warsawb110bad2006-07-21 14:51:07 +0000257- The email package has improved RFC 2231 support, specifically for
258 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
259 (name*0=<blah>) parameter continuations. This may change the types of
260 values returned from email.message.Message.get_param() and friends.
261 Specifically in some cases where non-encoded continuations were used,
262 get_param() used to return a 3-tuple of (None, None, string) whereas now it
263 will just return the string (since non-encoded continuations don't have
264 charset and language parts).
265
266 Also, whereas % values were decoded in all parameter continuations, they are
267 now only decoded in encoded parameter parts.
268
Ronald Oussoren3075e162006-07-25 20:28:55 +0000269- Bug #1517990: IDLE keybindings on MacOS X now work correctly
270
271- Bug #1517996: IDLE now longer shows the default Tk menu when a
272 path browser, class browser or debugger is the frontmost window on MacOS X
273
Barry Warsaw00decd72006-07-27 23:43:15 +0000274- Patch #1520294: Support for getset and member descriptors in types.py,
275 inspect.py, and pydoc.py. Specifically, this allows for querying the type
276 of an object against these built-in types and more importantly, for getting
277 their docstrings printed in the interactive interpreter's help() function.
278
Ronald Oussoren3075e162006-07-25 20:28:55 +0000279
Neal Norwitza1f10902006-07-12 07:28:29 +0000280Extension Modules
281-----------------
282
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000283- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
284 a socket operation on a socket with a timeout, the exception will be
285 caught correctly. Previously, the exception was not caught.
286
Thomas Heller1393d6a2006-07-28 21:43:20 +0000287- Patch #1529514: The _ctypes extension is now compiled on more
288 openbsd target platforms.
289
Tim Peters9cab5932006-07-28 00:30:00 +0000290- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
291 a memory leak, affecting pickles and deep copies.
292
Tim Petersbc24eee2006-07-27 01:14:53 +0000293- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000294 Paul Eggert.
295
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000296- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
297
Thomas Hellerce049a02006-07-14 17:51:14 +0000298- Patch #1521817: Index range checking on ctypes arrays containing
299 exactly one element enabled again. This allows iterating over these
300 arrays, without the need to check the array size before.
301
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000302- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000303 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000304 /dev/null in certain cases; this is now fixed.
305
Thomas Heller47d7a062006-07-12 08:43:47 +0000306- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
307 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000308
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000309- Because of a misspelled preprocessor symbol, ctypes was always
310 compiled without thread support; this is now fixed.
311
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000312- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
313 methods now allow their database parameter to be None as the
314 sleepycat API allows.
315
Matt Flemingec926502006-07-28 11:27:27 +0000316- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
317 bluetooth API compared with Linux and FreeBSD.
318
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000319Tests
320-----
321
322- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
323 how long the test file should take to play. Now accepts taking 2.93 secs
324 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
325
Georg Brandl4793aa32006-07-28 18:31:39 +0000326- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
327 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
328 run via ``regrtest.py``. Now they do.

337
338- PythonLauncher now works correctly when the path to the script contains
339 characters that are treated specially by the shell (such as quotes).
340
341- Bug #1527397: PythonLauncher now launches scripts with the working directory
342 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000343 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000344 expect.

352Core and builtins
353-----------------
354
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000355- Bug #1441486: The literal representation of -(sys.maxint - 1)
356 again evaluates to a int object, not a long.
357
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000358- Bug #1501934: The scope of global variables that are locally assigned
359 using augmented assignment is now correctly determined.
360
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000361- Bug #927248: Recursive method-wrapper objects can now safely
362 be released.
363
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000364- Bug #1417699: Reject locale-specific decimal point in float()
365 and atof().
366
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000367- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
368 omit a default "error" argument for NULL pointer. This allows
369 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000370
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000371- Bug #1519018: 'as' is now validated properly in import statements.
372
Neal Norwitz28746ab2006-07-09 22:14:42 +0000373- On 64 bit systems, int literals that use less than 64 bits are
374 now ints rather than longs.
375
Neal Norwitzed657552006-07-10 00:04:44 +0000376- Bug #1512814, Fix incorrect lineno's when code at module scope
377 started after line 256.
378
Tim Peters32a83612006-07-10 21:08:24 +0000379- New function ``sys._current_frames()`` returns a dict mapping thread
380 id to topmost thread stack frame. This is for expert use, and is
381 especially useful for debugging application deadlocks. The functionality
382 was previously available in Fazal Majid's ``threadframe`` extension
383 module, but it wasn't possible to do this in a wholly threadsafe way from
384 an extension.

393
Tim Peters32a83612006-07-10 21:08:24 +0000394- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000395 environment variable to be set in order to the SDK environment
396 for finding the compiler, include files, etc.

401
Thomas Woutersadd19112006-07-05 11:03:49 +0000402- string.Template() now correctly handles tuple-values. Previously,
403 multi-value tuples would raise an exception and single-value tuples would
404 be treated as the value they contain, instead.
405
Martin v. Löwisede77f52006-07-03 13:01:35 +0000406- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
407 even if some data are received.

413 degrees and radians.
414
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000415- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000416 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000417
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000418- Bug #1514703: Only setup canvas window in turtle when the canvas
419 is created.
420
Martin v. Löwis7596e832006-07-01 15:33:37 +0000421- Bug #1513223: .close() of a _socketobj now releases the underlying
422 socket again, which then gets closed as it becomes unreferenced.
423
Fred Drake10497c82006-06-29 02:57:48 +0000424- Bug #1504333: Make sgmllib support angle brackets in quoted
425 attribute values.
426
427- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
428 sgmllib ('[' and ']' were not accepted).
429
Georg Brandl1be63af2006-06-28 20:23:25 +0000430- Fix a bug in the turtle module's end_fill function.
431
Brett Cannon53ab5b72006-06-22 16:49:14 +0000432- Bug #1510580: The 'warnings' module improperly required that a Warning
433 category be either a types.ClassType and a subclass of Warning. The proper
434 check is just that it is a subclass with Warning as the documentation states.
435
Georg Brandlad29e632006-06-21 17:45:17 +0000436- The compiler module now correctly compiles the new try-except-finally
437 statement (bug #1509132).
438
Neal Norwitz60373cd2006-06-22 06:30:50 +0000439- The wsgiref package is now installed properly on Unix.
440
Vinay Sajip28e57612006-07-01 10:45:20 +0000441- A bug was fixed in logging.config.fileConfig() which caused a crash on
442 shutdown when fileConfig() was called multiple times.
443
Gerhard Häring762fbd32006-07-02 17:48:30 +0000444- The sqlite3 module did cut off data from the SQLite database at the first
445 null character before sending it to a custom converter. This has been fixed
446 now.
447
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000448Extension Modules
449-----------------
450
Tim Peters112aad32006-07-19 00:03:19 +0000451- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
452 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
453 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000454
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000455- Assigning None to pointer type fields in ctypes structures possible
456 overwrote the wrong fields, this is fixed now.
457
458- Fixed a segfault in _ctypes when ctypes.wintypes were imported
459 on non-Windows platforms.
460
461- Bug #1518190: The ctypes.c_void_p constructor now accepts any
462 integer or long, without range checking.
463
464- Patch #1517790: It is now possible to use custom objects in the ctypes
465 foreign function argtypes sequence as long as they provide a from_param
466 method, no longer is it required that the object is a ctypes type.
467
468- The '_ctypes' extension module now works when Python is configured
469 with the --without-threads option.
470
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000471- Bug #1513646: os.access on Windows now correctly determines write
472 access, again.
473
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000474- Bug #1512695: cPickle.loads could crash if it was interrupted with
475 a KeyboardInterrupt.
476
Neal Norwitza12aa882006-07-06 06:45:08 +0000477- Bug #1296433: parsing XML with a non-default encoding and
478 a CharacterDataHandler could crash the interpreter in pyexpat.
479
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000480- Patch #1516912: improve Modules support for OpenVMS.

483-----
484
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000485- Automate Windows build process for the Win64 SSL module.
486
Tim Peters32a83612006-07-10 21:08:24 +0000487- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000488 Previously, the slight difference could cause compilation errors of the
489 'zlib' module on systems with more than one version of zlib.
490
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000491- The MSI compileall step was fixed to also support a TARGETDIR
492 with spaces in it.
493
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000494- Bug #1517388: sqlite3.dll is now installed on Windows independent
495 of Tcl/Tk.
496
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000497- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000498 trying to be installed even though it's empty.

510 documentation for the warnings module.
511
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000512- Patch #1509163: MS Toolkit Compiler no longer available.

522Core and builtins
523-----------------
524
Georg Brandla56b9152006-06-19 06:35:54 +0000525- Patch #1507676: Error messages returned by invalid abstract object operations
526 (such as iterating over an integer) have been improved and now include the
527 type of the offending object to help with debugging.
528
Brett Cannonea3912b2006-06-13 21:46:41 +0000529- Bug #992017: A classic class that defined a __coerce__() method that returned
530 its arguments swapped would infinitely recurse and segfault the interpreter.
531
Neal Norwitz909eb122006-06-12 02:13:21 +0000532- Fix the socket tests so they can be run concurrently.
533
Neal Norwitzb9845e72006-06-12 02:11:18 +0000534- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000535 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000536
Brett Cannon22565aa2006-06-09 22:31:23 +0000537- Bug #532646: object.__call__() will continue looking for the __call__
538 attribute on objects until one without one is found. This leads to recursion
539 when you take a class and set its __call__ attribute to an instance of the
540 class. Originally fixed for classic classes, but this fix is for new-style.
541 Removes the infinite_rec_3 crasher.
542
Georg Brandl24250812006-06-09 18:45:48 +0000543- The string and unicode methods startswith() and endswith() now accept
544 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
545
Brett Cannonde3b0522006-06-08 17:00:45 +0000546- Buffer objects, at the C level, never used the char buffer
547 implementation even when the char buffer for the wrapped object was
548 explicitly requested (originally returned the read or write buffer).
549 Now a TypeError is raised if the char buffer is not present but is
550 requested.
551
Georg Brandlddbaa662006-06-04 21:56:52 +0000552- Patch #1346214: Statements like "if 0: suite" are now again optimized
553 away like they were in Python 2.4.
554
Georg Brandlb7c8f542006-05-27 12:30:25 +0000555- Builtin exceptions are now full-blown new-style classes instead of
556 instances pretending to be classes, which speeds up exception handling
557 by about 80% in comparison to 2.5a2.
558
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000559- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
560 Unicode 4.1.
561
Georg Brandlf4ef1162006-05-26 18:03:31 +0000562- Patch #921466: sys.path_importer_cache is now used to cache valid and
563 invalid file paths for the built-in import machinery which leads to
564 fewer open calls on startup.
565
Tim Peters696cf432006-05-24 21:10:40 +0000566- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
567 of-2 bases. The largest speedup is for inputs with about 1000 decimal
568 digits. Conversion from non-power-of-2 bases remains quadratic-time in
569 the number of input digits (it was and remains linear-time for bases
570 2, 4, 8, 16 and 32).
571
Tim Petersb713ec22006-05-23 18:45:30 +0000572- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
573 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
574 an integer close to ``sys.maxint``. This was repaired by patch
575 #1335972, which also gives a nice speedup.
576
Richard Jonescebbefc2006-05-23 18:28:17 +0000577- Patch #1337051: reduced size of frame objects.
578
579- PyErr_NewException now accepts a tuple of base classes as its
580 "base" parameter.
581
Richard Jones7c88dcc2006-05-23 10:37:38 +0000582- Patch #876206: function call speedup by retaining allocated frame
583 objects.
584
Georg Brandl7b90e162006-05-18 07:01:27 +0000585- Bug #1462152: file() now checks more thoroughly for invalid mode
586 strings and removes a possible "U" before passing the mode to the
587 C library function.
588
Neal Norwitz1004a532006-05-15 07:17:23 +0000589- Patch #1488312, Fix memory alignment problem on SPARC in unicode
590
Neal Norwitz373f0a72006-05-15 07:04:36 +0000591- Bug #1487966: Fix SystemError with conditional expression in assignment
592
Martin v. Löwis879768d2006-05-11 13:28:43 +0000593- WindowsError now has two error code attributes: errno, which carries
594 the error values from errno.h, and winerror, which carries the error
595 values from winerror.h. Previous versions put the winerror.h values
596 (from GetLastError()) into the errno attribute.
597
Martin v. Löwis77736712006-05-04 05:51:03 +0000598- Patch #1475845: Raise IndentationError for unexpected indent.
599
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000600- Patch #1479181: split open() and file() from being aliases for each other.
601
Tim Peters44bd9862006-06-01 13:49:23 +0000602- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
603 methods were always silently ignored by dictionaries when comparing keys.
604 They are now passed through (except when using the C API function
605 ``PyDict_GetItem()``, whose semantics did not change).
606
607- Bug #1456209: In some obscure cases it was possible for a class with a
608 custom ``__eq__()`` method to confuse dict internals when class instances
609 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
610 No, you don't have any code that did this ;-)

616
617- Patch #1462338: Upgrade pyexpat to expat 2.0.0
618
Brett Cannon6ee7d012006-06-08 16:23:04 +0000619- Change binascii.hexlify to accept a read-only buffer instead of only a char
620 buffer and actually follow its documentation.
621
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000622- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
623
Nick Coghlanc649ec52006-05-29 12:43:05 +0000624- Patch #1478788 (modified version): The functional extension module has
625 been renamed to _functools and a functools Python wrapper module added.
626 This provides a home for additional function related utilities that are

Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000629- Patch #1493701: performance enhancements for struct module.
630
Georg Brandl378d5922006-05-17 14:26:50 +0000631- Patch #1490224: time.altzone is now set correctly on Cygwin.
632
Georg Brandl8d3342b2006-05-16 07:38:27 +0000633- Patch #1435422: zlib's compress and decompress objects now have a
634 copy() method.
635
Andrew MacIntyre92913322006-06-13 15:04:24 +0000636- Patch #1454481: thread stack size is now tunable at runtime for thread
637 enabled builds on Windows and systems with Posix threads support.
638
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000639- On Win32, os.listdir now supports arbitrarily-long Unicode path names
640 (up to the system limit of 32K characters).
641
642- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
643 As a result, these functions now raise WindowsError instead of OSError.
644
Tim Peters7a822da2006-05-25 21:50:17 +0000645- ``time.clock()`` on Win64 should use the high-performance Windows
646 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
647 Windows platforms).
648
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000649- Calling Tk_Init twice is refused if the first call failed as that
650 may deadlock.
651
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000652- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
653 accept it without potentially using an uninitialized pointer.
654
655- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
656 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

661
Gregory P. Smith372b5832006-06-05 18:48:21 +0000662- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
663 parameter is supplied. [SF pybsddb bug #1477863]
664
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000665- bsddb: the __len__ method of a DB object has been fixed to return correct
666 results. It could previously incorrectly return 0 in some cases.
667 Fixes SF bug 1493322 (pybsddb bug 1184012).
668
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000669- bsddb: the bsddb.dbtables Modify method now raises the proper error and
670 aborts the db transaction safely when a modifier callback fails.
671 Fixes SF python patch/bug #1408584.
672
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000673- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000674 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000675 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
676 database calls that would previously deadlock. [SF python bug #775414]

704
Martin v. Löwisd8251432006-06-14 05:21:04 +0000705- Patch #1455898: The MBCS codec now supports the incremental mode for
706 double-byte encodings.
707
Tim Peters43898b42006-06-14 04:09:25 +0000708- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
709 guarantee that adjacent triples in the return list always describe
710 non-adjacent blocks. Previously, a pair of matching blocks could end
711 up being described by multiple adjacent triples that formed a partition
712 of the matching pair.
713
Greg Ward0e0c9f42006-06-11 16:24:11 +0000714- Bug #1498146: fix optparse to handle Unicode strings in option help,

721
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000722- The wsgiref package has been added to the standard library.
723
Nick Coghlan676725d2006-06-08 13:54:49 +0000724- The functions update_wrapper() and wraps() have been added to the functools
725 module. These make it easier to copy relevant metadata from the original
726 function when writing wrapper functions.
727
Tim Petersd6a9eef2006-06-05 01:48:21 +0000728- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
729 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000730
Martin v. Löwis3f767792006-06-04 19:36:28 +0000731- Patch #1359618: Speed up charmap encoder by using a trie structure
732 for lookup.
733
Tim Petersd609b1a2006-06-02 23:22:51 +0000734- The functions in the ``pprint`` module now sort dictionaries by key
735 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
736 if and only if its display required more than one line, although that
737 wasn't documented. The new behavior increases predictability; e.g.,
738 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
739
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000740- Patch #1497027: try HTTP digest auth before basic auth in urllib2

Georg Brandlb89316f2006-05-17 15:51:16 +0000750- Patch #1180296: Two new functions were added to the locale module:
751 format_string() to get the effect of "format % items" but locale-aware,
752 and currency() to format a monetary number with currency sign.
753
Georg Brandle3a25832006-05-17 14:56:04 +0000754- Patch #1486962: Several bugs in the turtle Tk demo module were fixed

761 stdout arguments, making it possible to redirect input and output
762 for remote debugging.
763
764- Patch #1484695: Update the tarfile module to version 0.8. This fixes
765 a couple of issues, notably handling of long file names using the
766 GNU LONGNAME extension.
767
768- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
769 new flag when ``name`` is already the name of an option flag.

812
813*Release date: 27-APR-2006*
814
815Core and builtins
816-----------------
817
Thomas Heller1b046642006-04-18 18:51:06 +0000818- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
819 by converting these apis from macros into exported functions again:
820
821 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
822 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
823 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
824 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
825 PyRun_String Py_CompileString
826
Martin v. Löwis45294a92006-04-18 06:24:08 +0000827- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
828
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000829- All uses of PyStructSequence_InitType have been changed to initialize
830 the type objects only once, even if the interpreter is initialized
831 multiple times.
832
Neal Norwitz61546162006-04-14 05:20:28 +0000833- Bug #1454485, array.array('u') could crash the interpreter. This was
834 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
835 to unicode when it didn't make sense. 'u#' now requires a unicode string.
836
837- Py_UNICODE is unsigned. It was always documented as unsigned, but
838 due to a bug had a signed value in previous versions.
839
Tim Peters3a5e8b12006-04-11 01:44:07 +0000840- Patch #837242: ``id()`` of any Python object always gives a positive
841 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
842 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000843 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000844 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000845
Tim Peters3a5e8b12006-04-11 01:44:07 +0000846 def __hash__(self):
847 return id(self) # WRONG
848
849 because a hash result must be a (short) Python int but it was always
850 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000851 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000852 was always usable as a hash value before this patch. That's no longer
853 necessarily so.
854
855- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000856 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000857 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000858 #1454844)
859
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000860- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
861 involving generators that have paused outside of any ``try`` or ``with``
862 blocks. (In 2.5a1, a paused generator that was part of a reference
863 cycle could not be garbage collected, regardless of whether it was
864 paused in a ``try`` or ``with`` block.)

881 a temporary db (file=None) with the 'n' flag to truncate on open.
882
883- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
884 as older versions cause excessive test failures.

890-------
891
Peter Astrand7d1d4362006-07-14 14:04:45 +0000892- Bug #1223937: subprocess.CalledProcessError reports the exit status
893 of the process using the returncode attribute, instead of
894 abusing errno.
895
Tim Peters711bf302006-04-25 03:31:36 +0000896- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
897 a doctest to be skipped (the code is not run, and the expected output
898 or exception is ignored).
899
Nick Coghlanda2268f2006-04-24 04:37:15 +0000900- Fixed contextlib.nested to cope with exceptions being raised and
901 caught inside exit handlers.
902
Greg Wardab05edc2006-04-23 03:47:58 +0000903- Updated optparse module to Optik 1.5.1 (allow numeric constants in
904 hex, octal, or binary; add ``append_const`` action; keep going if
905 gettext cannot be imported; added ``OptionParser.destroy()`` method;
906 added ``epilog`` for better help generation).
907
Tim Peters21fbd572006-04-21 21:18:10 +0000908- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
909 called from a thread spawned as a side effect of importing a module.
910
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000911- The pydoc module now supports documenting packages contained in
912 .zip or .egg files.
913
914- The pkgutil module now has several new utility functions, such
915 as ``walk_packages()`` to support working with packages that are either
916 in the filesystem or zip files.
917
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000918- The mailbox module can now modify and delete messages from
919 mailboxes, in addition to simply reading them. Thanks to Gregory
920 K. Johnson for writing the code, and to the 2005 Google Summer of
921 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000922
Tim Petersc7605f22006-04-17 21:12:33 +0000923- The ``__del__`` method of class ``local`` in module ``_threading_local``
924 returned before accomplishing any of its intended cleanup.
925

950-----
951
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000952- The Makefile now has a reindent target, which runs reindent.py on
953 the library.
954
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000955- Patch #1470875: Building Python with MS Free Compiler
956
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000957- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000958
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000959- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
960 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000961 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000962 CXX from --with-cxx-main, see description in README.
963
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000964- Patch #1429775: Link extension modules with the shared libpython.
965
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000966- Fixed a libffi build problem on MIPS systems.
967
Tim Peters8931ff12006-05-13 23:28:20 +0000968- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
969 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
970 and "%zu" for unsigned integers of type ``size_t``.
971
Anthony Baxter51bcb682006-04-05 14:51:42 +0000972Tests
973-----
974
Nick Coghlanda2268f2006-04-24 04:37:15 +0000975- test_contextlib now checks contextlib.nested can cope with exceptions
976 being raised and caught inside exit handlers.
977
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000978- test_cmd_line now checks operation of the -m and -c command switches
979
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000980- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
981 it separately and by hand. It also wasn't cleaning up its changes to
982 the current Decimal context.
983
Thomas Woutersabd08882006-04-26 15:53:30 +0000984- regrtest.py now has a -M option to run tests that test the new limits of
985 containers, on 64-bit architectures. Running these tests is only sensible
986 on 64-bit machines with more than two gigabytes of memory. The argument
987 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000995Documentation
996-------------
997
Tim Petersb06d28c2006-05-12 01:57:59 +0000998- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
999
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001000- PEP 343: Added Context Types section to the library reference
1001 and attempted to bring other PEP 343 related documentation into
1002 line with the implementation and/or python-dev discussions.
1003
Tim Peters8dc73d22006-04-24 02:03:16 +00001004- Bug #1337990: clarified that ``doctest`` does not support examples
1005 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001008What's New in Python 2.5 alpha 1?
1009=================================
1010
Anthony Baxterebed3f62006-04-03 15:03:44 +00001011*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001012
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001013Core and builtins
1014-----------------
1015
Nick Coghlan43832302006-04-23 17:04:07 +00001016- PEP 338: -m command line switch now delegates to runpy.run_module
1017 allowing it to support modules in packages and zipfiles
1018
Martin v. Löwisc661b882006-04-20 04:54:23 +00001019- On Windows, .DLL is not an accepted file name extension for
1020 extension modules anymore; extensions are only found if they
1021 end in .PYD.
1022
Martin v. Löwisea62d252006-04-03 10:56:49 +00001023- Bug #1421664: sys.stderr.encoding is now set to the same value as
1024 sys.stdout.encoding.
1025
Neal Norwitz92e212f2006-04-03 04:48:37 +00001026- __import__ accepts keyword arguments.
1027
Georg Brandlccadf842006-03-31 18:54:53 +00001028- Patch #1460496: round() now accepts keyword arguments.
1029
Anthony Baxter262c00a2006-03-30 10:53:17 +00001030- Fixed bug #1459029 - unicode reprs were double-escaped.
1031
Hye-Shik Changd478f342006-03-23 12:32:36 +00001032- Patch #1396919: The system scope threads are reenabled on FreeBSD
1033 5.4 and later versions.
1034
Neal Norwitze98ccf62006-03-23 05:39:47 +00001035- Bug #1115379: Compiling a Unicode string with an encoding declaration
1036 now gives a SyntaxError.
1037
Georg Brandlabd1ff82006-03-18 07:59:59 +00001038- Previously, Python code had no easy way to access the contents of a
1039 cell object. Now, a ``cell_contents`` attribute has been added
1040 (closes patch #1170323).
1041
Tim Peterscf79aac2006-03-16 01:14:46 +00001042- Patch #1123430: Python's small-object allocator now returns an arena to
1043 the system ``free()`` when all memory within an arena becomes unused
1044 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1045 freed. Some applications will see a drop in virtual memory size now,
1046 especially long-running applications that, from time to time, temporarily
1047 use a large number of small objects. Note that when Python returns an
1048 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001049 platform C library will in turn return that memory to the operating system.
1050 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001051 appears to be effective at least on Microsoft C and gcc-based systems.
1052 Thanks to Evan Jones for hard work and patience.
1053
Georg Brandl533ff6f2006-03-08 18:09:27 +00001054- Patch #1434038: property() now uses the getter's docstring if there is
1055 no "doc" argument given. This makes it possible to legitimately use
1056 property() as a decorator to produce a read-only property.
1057
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001058- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1059 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1060 of requiring an int or long in slicing and a few other contexts, enabling
1061 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1062
Neal Norwitz995acdf2006-03-07 05:01:00 +00001063- Fixed various bugs reported by Coverity's Prevent tool.
1064
Brett Cannonbf364092006-03-01 04:25:17 +00001065- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1066 new exception base class, BaseException, which has a new message attribute.
1067 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1068 Raising a string exception now raises a DeprecationWarning.
1069
Thomas Woutersfb609f42006-02-28 16:37:25 +00001070- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1071 explicitly relative, using 'from .module import name' to mean 'from the same
1072 package as this module is in. Imports without dots still default to the
1073 old relative-then-absolute, unless 'from __future__ import
1074 absolute_import' is used.
1075
Brett Cannona7446e32006-02-27 23:39:10 +00001076- Properly check if 'warnings' raises an exception (usually when a filter set
1077 to "error" is triggered) when raising a warning for raising string
1078 exceptions.
1079
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001080- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001081 The name was removed from Include/code.h.
1082
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001083- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001084
Guido van Rossum1968ad32006-02-25 22:38:04 +00001085- Patch 1433928:
1086 - The copy module now "copies" function objects (as atomic objects).
1087 - dict.__getitem__ now looks for a __missing__ hook before raising
1088 KeyError.
1089
Tim Peters84ef21c2006-02-28 20:39:06 +00001090- PEP 343: with statement implemented. Needs ``from __future__ import
1091 with_statement``. Use of 'with' as a variable will generate a warning.
1092 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001093 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001094 The following objects have __context__ methods:
1095 - The built-in file type.
1096 - The thread.LockType type.
1097 - The following types defined by the threading module:
1098 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1099 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001100
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001101- Fix the encodings package codec search function to only search
1102 inside its own package. Fixes problem reported in patch #1433198.
1103
1104 Note: Codec packages should implement and register their own
1105 codec search function. PEP 100 has the details.
1106
Tim Peters9ea89d22006-06-04 03:26:02 +00001107- PEP 353: Using ``Py_ssize_t`` as the index type.
1108
1109- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1110 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1111 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1112 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1113 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001114
Neal Norwitzfc76d632006-01-10 06:03:13 +00001115- Patch #1400181, fix unicode string formatting to not use the locale.
1116 This is how string objects work. u'%f' could use , instead of .
1117 for the decimal point. Now both strings and unicode always use periods.
1118
Neal Norwitz671b9e32006-01-09 07:07:12 +00001119- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1120 configure would break checking curses.h.
1121
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001122- Bug #959576: The pwd module is now builtin. This allows Python to be
1123 built on UNIX platforms without $HOME set.
1124
Neal Norwitzc10978f2005-12-19 06:07:16 +00001125- Bug #1072182, fix some potential problems if characters are signed.
1126
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001127- Bug #889500, fix line number on SyntaxWarning for global declarations.
1128
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001129- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1130
Neal Norwitze7214a12005-12-18 05:03:17 +00001131- Support for converting hex strings to floats no longer works.
1132 This was not portable. float('0x3') now raises a ValueError.
1133
Barry Warsaw2a38a862005-12-18 01:27:35 +00001134- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001135 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001136 is now displayed in interactive prompt banner.
1137
Georg Brandlfa166682005-12-17 21:45:17 +00001138- Implementation of PEP 341 - Unification of try/except and try/finally.
1139 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001140 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001141
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001142- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1143 now encodes backslash correctly.
1144
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001145- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1146
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001147- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001148 and long longs.
1149
Neal Norwitz67715f02005-11-09 06:59:35 +00001150- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001151 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001152 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001153
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001154- Replaced most Unicode charmap codecs with new ones using the
1155 new Unicode translate string feature in the builtin charmap
1156 codec; the codecs were created from the mapping tables available
1157 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1158 encodings now include a mapping for the Apple logo)
1159
Tim Peterse3547fd2005-12-16 23:13:57 +00001160- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001161
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001162- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001163
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001164- A new AST parser implementation was completed. The abstract
1165 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001166 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001167
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001168- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001169 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1170
Neal Norwitz708e51a2005-10-03 04:48:15 +00001171- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1172
Neal Norwitz11bd1192005-10-03 00:54:56 +00001173- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1174 Provide a warning when a directory is passed on the command line.
1175
Neal Norwitz40d37812005-10-02 01:48:49 +00001176- Fix segfault with invalid coding.
1177
1178- SF bug #772896: unknown encoding results in MemoryError.
1179
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001180- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001181 supported a __len__() method which evaluated to False when the iterator
1182 was empty.
1183
Guido van Rossum630db602005-09-20 18:49:54 +00001184- On 64-bit platforms, when __len__() returns a value that cannot be
1185 represented as a C int, raise OverflowError.
1186
Skip Montanarof8948ca2005-09-19 03:54:46 +00001187- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001188 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001189
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001190- SF bug #893549: parsing keyword arguments was broken with a few format
1191 codes.
1192
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001193- Changes donated by Elemental Security to make it work on AIX 5.3
1194 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1195 bug #105470: test_pwd fails on 64bit system (Opteron).
1196
Guido van Rossum539c6622005-09-14 17:49:54 +00001197- Changes donated by Elemental Security to make it work on HP-UX 11 on
1198 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1199
Georg Brandl4550b8d2005-08-26 06:43:52 +00001200- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001201 (fixes bug #1119418).
1202
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001203- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1204
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001205- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1206 exceptions that cause a function to exit.
1207
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001208- The implementation of set() and frozenset() was revised to use its
1209 own internal data structure. Memory consumption is reduced by 1/3
1210 and there are modest speed-ups as well. The API is unchanged.
1211
Tim Petersde7990b2005-07-17 23:45:23 +00001212- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1213
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001214- SF bug #1229429: PyObject_CallMethod failed to decrement some
1215 reference counts in some error exit cases.

Tim Petersecc6e6a2005-07-10 22:30:55 +00001217- SF bug #1185883: Python's small-object memory allocator took over
1218 a block managed by the platform C library whenever a realloc specified
1219 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001220 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001221 portable way to copy data from the C-managed block into Python's
1222 small-object space without risking a memory fault. Python's small-object
1223 realloc now leaves such blocks under the control of the platform C
1224 realloc.
1225
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001226- SF bug #1232517: An overflow error was not detected properly when
1227 attempting to convert a large float to an int in os.utime().
1228
Raymond Hettinger3296e692005-06-29 23:29:56 +00001229- SF bug #1224347: hex longs now print with lowercase letters just
1230 like their int counterparts.
1231
Michael W. Hudson188d4362005-06-20 16:52:57 +00001232- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1233 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1234 interpreter states; back out that fix and do a better job (see
1235 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1236 for a longer write-up of the problem).
1237
Michael W. Hudsondf888462005-06-03 14:41:55 +00001238- SF patch #1180995: marshal now uses a binary format by default when
1239 serializing floats.
1240
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001241- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1242 the routines that promise to produce IEEE 754 binary representations
1243 of floats now simply copy bytes around.
1244
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001245- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1246 278.
1247
Brett Cannonc3647ac2005-04-26 03:45:26 +00001248- patch #1109424: int, long, float, complex, and unicode now check for the
1249 proper magic slot for type conversions when subclassed. Previously the
1250 magic slot was ignored during conversion. Semantics now match the way
1251 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001252 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001253 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001254 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001255
Barry Warsawc8d907c2005-04-19 23:43:40 +00001256- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1257 NULL, now raise an AttributeError when attempting to set or delete the
1258 attribute. Previously a TypeError was raised, but this was inconsistent
1259 with the equivalent pure-Python implementation.
1260
Michael W. Hudson774479c2005-04-18 08:46:17 +00001261- It is now safe to call PyGILState_Release() before
1262 PyEval_InitThreads() (note that if there is reason to believe there
1263 are multiple threads around you still must call PyEval_InitThreads()
1264 before using the Python API; this fix is for extension modules that
1265 have no way of knowing if Python is multi-threaded yet).
1266
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001267- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1268 disabled caused a crash.
1269
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001270- Bug #1165306: instancemethod_new allowed the creation of a method
1271 with im_class == im_self == NULL, which caused a crash when called.
1272
Tim Petersecc6e6a2005-07-10 22:30:55 +00001273- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001274 fixes the crash seen in bug #1165761
1275
Raymond Hettinger96229b12005-03-11 06:49:40 +00001276- Added two new builtins, any() and all().
1277
Brett Cannon409d8f22005-03-05 06:47:57 +00001278- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001279 (e.g., ``class C(): pass`` is no longer a syntax error).
1280 Patch #1176012 added support to the 'parser' module and 'compiler' package
1281 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001282
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001283- Patch #1115086: Support PY_LONGLONG in structmember.
1284
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001285- Bug #1155938: new style classes did not check that __init__() was
1286 returning None.
1287
Tim Petersecc6e6a2005-07-10 22:30:55 +00001288- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001289 ('\') with a specific error message.
1290
Martin v. Löwisff232d72005-03-03 09:24:38 +00001291- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1292
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001293- Bug #1124295: the __name__ attribute of file objects was
1294 inadvertently made inaccessible in restricted mode.
1295
Tim Petersecc6e6a2005-07-10 22:30:55 +00001296- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001297 an ferror() call.
1298
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001299- min() and max() now support key= arguments with the same meaning as in
1300 list.sort().
1301
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001302- The peephole optimizer now performs simple constant folding in expressions:
1303 (2+3) --> (5).
1304
Raymond Hettingera422c342005-01-11 03:03:27 +00001305- set and frozenset objects can now be marshalled. SF #1098985.
1306
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001307- Bug #1077106: Poor argument checking could cause memory corruption
1308 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001309
Jeremy Hyltonab630502005-02-04 18:44:06 +00001310- The parser did not complain about future statements in illegal
1311 positions. It once again reports a syntax error if a future
1312 statement occurs after anything other than a doc string.
1313
Neil Schemenauercf52c072005-08-12 17:34:58 +00001314- Change the %s format specifier for str objects so that it returns a
1315 unicode instance if the argument is not an instance of basestring and
1316 calling __str__ on the argument returns a unicode instance.
1317
Tim Petersf4e69282006-02-27 17:15:31 +00001318- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1319 current thread state when the auto-GIL-state machinery knows about
1320 it (since the thread state is being deleted, continuing to remember it
1321 can't help, but can hurt if another thread happens to get created with
1322 the same thread id).
1323
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001324Extension Modules

1341
1342- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1343
1344- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001345 is deprecated. The undocumented re.engine variable no longer exists.
1346

1349
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001350- The unicodedata module was updated to the 4.1 version of the Unicode
1351 database. The 3.2 version is still available as unicodedata.db_3_2_0
1352 for applications that require this specific version (such as IDNA).
1353
Neal Norwitzb62c4332006-03-04 18:35:47 +00001354- The timing module is no longer built by default. It was deprecated
1355 in PEP 4 in Python 2.0 or earlier.
1356
Guido van Rossum1968ad32006-02-25 22:38:04 +00001357- Patch 1433928: Added a new type, defaultdict, to the collections module.

1359
Georg Brandldbd83392006-02-20 09:42:33 +00001360- Bug #854823: socketmodule now builds on Sun platforms even when

1375
Martin v. Löwis14694662006-02-03 12:54:16 +00001376- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1377 are reported, the limit on path name lengths is removed, and stat reports
1378 WindowsError now (instead of OSError).
1379

1455 the request code argument, which results in more C-like behaviour
1456 for large or negative values.
1457
Tim Petersecc6e6a2005-07-10 22:30:55 +00001458- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

1497
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001498- the cPickle module no longer accepts the deprecated None option in the
1499 args tuple returned by __reduce__().
1500
Raymond Hettingerb2594052004-12-05 09:25:51 +00001501- itertools.islice() now accepts None for the start and step arguments.
1502 This allows islice() to work more readily with slices:
1503 islice(s.start, s.stop, s.step)
1504
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001505- datetime.datetime() now has a strptime class method which can be used to

Tim Peters112aad32006-07-19 00:03:19 +00001513
Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001514- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1515 been renamed to have only a single underscore prefix. This was done to
1516 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001517
Nick Coghlan43832302006-04-23 17:04:07 +00001518- PEP 338: new module runpy defines a run_module function to support
1519 executing modules which provide access to source code or a code object
1520 via the PEP 302 import mechanisms.
1521
Anthony Baxter93f5b932006-04-03 08:05:07 +00001522- The email module's parsedate_tz function now sets the daylight savings
1523 flag to -1 (unknown) since it can't tell from the date whether it should

1530 in attribute values.
1531
Anthony Baxterc51ee692006-04-01 00:57:31 +00001532- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001533 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001534 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001535 module will not be built.
1536
Tim Petersc17976e2006-04-01 00:26:53 +00001537- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1538 aren't officially supported here, and trying to use them will probably
1539 raise an exception some day. But dicts have been allowed, and "mostly
1540 worked", so support for them won't go away without warning.
1541
Georg Brandl338ef7d2006-03-31 18:42:16 +00001542- Bug #1445068: getpass.getpass() can now be given an explicit stream
1543 argument to specify where to write the prompt.
1544
Georg Brandl22ec80b2006-03-31 18:25:44 +00001545- Patch #1462313, bug #1443328: the pickle modules now can handle classes
1546 that have __private names in their __slots__.
1547

1552
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001553- Queue.Queue objects now support .task_done() and .join() methods
1554 to make it easier to monitor when daemon threads have completed
1555 processing all enqueued tasks. Patch #1455676.
1556
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001557- popen2.Popen objects now preserve the command in a .cmd attribute.
1558
Thomas Hellerc61c0492006-03-22 10:09:27 +00001559- Added the ctypes ffi package.
1560
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001561- email 4.0 package now integrated. This is largely the same as the email 3.0
1562 package that was included in Python 2.3, except that PEP 8 module names are
1563 now used (e.g. mail.message instead of email.Message). The MIME classes
1564 have been moved to a subpackage (e.g. email.mime.text instead of
1565 email.MIMEText). The old names are still supported for now. Several
1566 deprecated Message methods have been removed and lots of bugs have been
1567 fixed. More details can be found in the email package documentation.
1568
Walter Dörwald40108c92006-03-27 08:15:44 +00001569- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1570 (a subclass of tuple) that provides incremental decoders and encoders
1571 (a way to use stateful codecs without the stream API). Python functions
1572 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1573 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1574 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001575
Walter Dörwald067db482006-03-15 22:17:27 +00001576- Patch #1359365: Calling next() on a closed StringIO.String object raises
1577 a ValueError instead of a StopIteration now (like file and cString.String do).
1578 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1579 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001580
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001581- A regrtest option -w was added to re-run failed tests in verbose mode.

Martin v. Löwis3e865952006-01-24 15:51:21 +00001629 specifications, raises IOErrors when proxies for unsupported protocols
1630 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00001653 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1654 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1655 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1656 Ronald L. Rivest offered this advice for Python:
1657
1658 "The consensus of researchers in this area (at least as
1659 expressed at the NIST Hash Function Workshop 10/31/05),
1660 is that SHA-256 is a good choice for the time being, but
1661 that research should continue, and other alternatives may
1662 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001663
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001664- Added a subset of Fredrik Lundh's ElementTree package. Available

Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001746- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001747 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00001748
Georg Brandl2f210b62005-06-26 22:09:06 +00001749- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
1750
Georg Brandlfbff1bc2005-06-26 21:36:25 +00001751- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
1752 error messages.
1753
Georg Brandl379f99d2005-06-26 21:09:38 +00001754- Bug #1108948: Cookie.py produced invalid JavaScript code.
1755
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001756- The tokenize module now detects and reports indentation errors.
1757 Bug #1224621.
1758
Raymond Hettinger68c04532005-06-10 11:05:19 +00001759- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001760 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001761 the generate_tokens() function now accepts a callable argument that
1762 terminates by raising StopIteration.
1763
Georg Brandl9166e1a2005-06-04 09:20:03 +00001764- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1765
Georg Brandl268e61c2005-06-03 14:28:50 +00001766- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1767 component of the path.
1768
Skip Montanaro174dd222005-05-14 20:54:16 +00001769- Patch #1120353: The xmlrpclib module provides better, more transparent,
1770 support for datetime.{datetime,date,time} objects. With use_datetime set
1771 to True, applications shouldn't have to fiddle with the DateTime wrapper
1772 class at all.
1773
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001774- distutils.commands.upload was added to support uploading distribution
1775 files to PyPI.
1776
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001777- distutils.commands.register now encodes the data as UTF-8 before posting
1778 them to PyPI.
1779
Raymond Hettinger267b8682005-03-27 10:47:39 +00001780- decimal operator and comparison methods now return NotImplemented
1781 instead of raising a TypeError when interacting with other types. This
1782 allows other classes to implement __radd__ style methods and have them
1783 work as expected.
1784
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001785- Bug #1163325: Decimal infinities failed to hash. Attempting to
1786 hash a NaN raised an InvalidOperation instead of a TypeError.
1787
Tim Petersecc6e6a2005-07-10 22:30:55 +00001788- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001789 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1790

1794 to build.
1795
Martin v. Löwis637431b2005-03-03 23:12:42 +00001796- Patch #1103407: Properly deal with tarfile iterators when untarring

Raymond Hettingerbab41432005-02-05 01:31:19 +00001821- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1822
Guido van Rossumd0641422005-02-03 15:01:24 +00001823- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1824 disables recursive traversal through instance attributes, which can
1825 be exploited in various ways.
1826
Tim Peterse3547fd2005-12-16 23:13:57 +00001827- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001828 flags on the HTTP listening socket.
1829
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001830- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1831 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1832
Fred Drakefbdeaad2006-07-29 16:56:15 +00001833- Patches #893642, #1039083: add allow_none, encoding arguments to
1834 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001835
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001836- Bug #1110478: Revert os.environ.update to do putenv again.
1837
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001838- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1839
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001840- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1841
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001842- Enhancements to the csv module:
1843
1844 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001845 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001846 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001847 + Dialect parameter parsing has been re-implemented to improve error
1848 reporting.
1849 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1850 dictates.
1851 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001852 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001853 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001854 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1855 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001856 + reader now allows \r characters to be quoted (previously it only allowed
1857 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001858 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001859 + Dialect classes passed to the module are no longer instantiated by
1860 the module before being parsed (the former validation scheme required
1861 this, but the mechanism was unreliable).
1862 + The dialect registry now contains instances of the internal
1863 C-coded dialect type, rather than references to python objects.
1864 + the internal c-coded dialect type is now immutable.
1865 + register_dialect now accepts the same keyword dialect specifications
1866 as the reader and writer, allowing the user to register dialects
1867 without first creating a dialect class.
1868 + a configurable limit to the size of parsed fields has been added -
1869 previously, an unmatched quote character could result in the entire
1870 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001871 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001872 the parser field size limit (returning the former limit). The initial
1873 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001874 + A line_num attribute has been added to the reader object, which tracks
1875 the number of lines read from the source iterator. This is not
1876 the same as the number of records returned, as records can span
1877 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001878 + reader and writer objects were not being registered with the cyclic-GC.
1879 This has been fixed.
1880
Brett Cannone6539c42005-01-08 02:43:53 +00001881- _DummyThread objects in the threading module now delete self.__block that is
1882 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1883 lock primitives tend to be limited in number and thus should not be wasted on
1884 a _DummyThread object. Fixes bug #1089632.
1885
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001886- The imghdr module now detects Exif files.
1887
Raymond Hettinger6065d322004-12-20 23:51:53 +00001888- StringIO.truncate() now correctly adjusts the size attribute.
1889 (Bug #951915).
1890
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001891- locale.py now uses an updated locale alias table (built using
1892 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1893 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001894 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001895
Raymond Hettinger3557f422004-12-07 12:02:02 +00001896- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1897
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001898- the pickle module no longer accepts the deprecated None option in the
1899 args tuple returned by __reduce__().
1900
Brett Cannon84667c02004-12-07 03:25:18 +00001901- optparse now optionally imports gettext. This allows its use in setup.py.
1902
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001903- the pickle module no longer uses the deprecated bin parameter.
1904
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001905- the shelve module no longer uses the deprecated binary parameter.
1906
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001907- the pstats module no longer uses the deprecated ignore() method.
1908
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001909- the filecmp module no longer uses the deprecated use_statcache argument.
1910
Raymond Hettinger664347b2004-12-04 21:21:53 +00001911- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1912 extended or overridden by subclasses. Formerly, the subclassed method would
1913 be ignored by the rest of the module. (Bug #1078905).
1914
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001915- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001916 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001917
Walter Dörwald36733692004-12-22 12:50:50 +00001918- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1919 once when a size argument is given. This prevents a buffer overflow in the
1920 tokenizer with very long source lines.
1921
Barry Warsaw538561e2006-01-01 21:48:54 +00001922- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1923 immediately after creating the object, without any intervening
1924 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001925
Skip Montanaro05885812005-01-16 20:48:27 +00001926- The reconvert.quote function can now emit triple-quoted strings. The
1927 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001928
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001929- ``UserString.MutableString`` now supports negative indices in
1930 ``__setitem__`` and ``__delitem__``
1931
Greg Ward40407942005-03-05 02:53:17 +00001932- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1933 correctly.
1934
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001935- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1936 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1937 character even if the user has passed a size parameter to get a proper
1938 line ending. Remove the special handling of a "\r\n" that has been split
1939 between two lines.
1940
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001941- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1942 about illegal code points. The codec now supports PEP 293 style error
1943 handlers.
1944
Walter Dörwald78a78b02005-09-01 12:04:29 +00001945- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001946 from the input stream, so that the output is a byte string in the correct
1947 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001948
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001949- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1950 considering it exactly like a '*'.
1951
Walter Dörwald007f8df2005-10-09 19:42:27 +00001952- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1953 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001954
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001955- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1956
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001957- Patch #1413711: Certain patterns of differences were making difflib
1958 touch the recursion limit.
1959
Walter Dörwald58917a62006-03-31 15:26:22 +00001960- Bug #947906: An object oriented interface has been added to the calendar
1961 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001962 called as a script (e.g. via ``python -mcalendar``). Localized month and
1963 weekday names can be ouput (even if an exotic encoding is used) using
1964 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001965

1987
Trent Mick8321b422005-07-26 02:29:21 +00001988- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1989 vulnerability in zlib 1.2.1 and 1.2.2.
1990
Brett Cannon08cd5982005-04-24 22:26:38 +00001991- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1992 flags that change binary compatibility. Changes were also made to
1993 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001994 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001995
Bob Ippolitoed233462005-03-29 13:47:59 +00001996- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1997 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1998 no longer exists). This configure patch makes things right.
1999
Martin v. Löwise2713be2005-03-08 15:03:08 +00002000- Bug #1158607: Build with --disable-unicode again.
2001
Brett Cannon46d96232005-02-16 00:07:19 +00002002- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2003 defined. Discovered as a result of not being able to build on OS X.
2004
Brett Cannon516592f2004-12-07 00:42:59 +00002005- setup.py now uses the directories specified in LDFLAGS using the -L option
2006 and in CPPFLAGS using the -I option for adding library and include
2007 directories, respectively, for compiling extension modules against. This has
2008 led to the core being compiled using the values in CPPFLAGS. It also removes
2009 the need for the special-casing of both DarwinPorts and Fink for darwin since
2010 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2011 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2012 Fink, ``-I/opt/local/include`` for DarwinPorts).
2013
Brett Cannon43802422005-02-10 20:48:03 +00002014- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2015 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2016 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2017 Closes bug #1096244. Thanks Gregory Bond.

2020-----
2021
Tim Petersc9d78aa2006-03-26 23:27:58 +00002022- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2023 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2024 is obtained via the ``PyObject_`` family, it must be released via the
2025 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2026 always been officially true, but when Python's small-object allocator was
2027 introduced, an attempt was made to cater to a few extension modules
2028 discovered at the time that obtained memory via ``PyObject_New`` but
2029 released it via ``PyMem_DEL``. It's years later, and if such code still
2030 exists it will fail now (probably with segfaults, but calling wrong
2031 low-level memory management functions can yield many symptoms).
2032
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002033- Added a C API for set and frozenset objects.
2034

2036
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002037- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2038 mapping argument now. This string is used as a mapping table. Byte values
2039 greater than the length of the string and 0xFFFE are treated as undefined
2040 mappings.
