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
Neal Norwitz56423e52006-08-13 18:11:08 +000015- Fix segfault when doing string formatting on subclasses of long.
16
Neal Norwitz1872b1c2006-08-12 18:44:06 +000017- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
18 with new-style classes.
19
20- Fix bug related to __len__ functions returning negative values with
21 classic classes.
22
Neal Norwitz8a87f5d2006-08-12 17:03:09 +000023- Patch #1538606, Fix __index__() clipping. There were some problems
24 discovered with the API and how integers that didn't fit into Py_ssize_t
25 were handled. This patch attempts to provide enough alternatives
26 to effectively use __index__.
27
Martin v. Löwisab2f8f72006-08-09 07:57:39 +000028- Bug #1536021: __hash__ may now return long int; the final hash
29 value is obtained by invoking hash on the long int.
30
Thomas Hellerab1049c2006-08-08 17:37:00 +000031- Bug #1536786: buffer comparison could emit a RuntimeWarning.
32
Georg Brandl7e3ba2a2006-08-06 08:23:54 +000033- Bug #1535165: fixed a segfault in input() and raw_input() when
34 sys.stdin is closed.
35
Thomas Heller74d36f02006-08-04 18:17:40 +000036- On Windows, the PyErr_Warn function is now exported from
37 the Python dll again.
38
Neal Norwitz4ffedad2006-08-04 04:58:47 +000039- Bug #1191458: tracing over for loops now produces a line event
40 on each iteration. Fixing this problem required changing the .pyc
41 magic number. This means that .pyc files generated before 2.5c1
42 will be regenerated.
43
Neal Norwitz0cbd8052006-08-04 05:09:28 +000044- Bug #1333982: string/number constants were inappropriately stored
45 in the byte code and co_consts even if they were not used, ie
46 immediately popped off the stack.
47
Georg Brandle9462c72006-08-04 18:03:37 +000048- Fixed a reference-counting problem in property().
49
Neal Norwitzff4b63b2006-08-04 04:50:21 +000050
51Library
52-------
53
Georg Brandl0a7d1bb2006-08-11 07:26:10 +000054- logging's atexit hook now runs even if the rest of the module has
55 already been cleaned up.
56
Guido van Rossum133f4e42006-08-10 17:42:50 +000057- Bug #1112549, DoS attack on cgi.FieldStorage.
58
Neal Norwitzff4b63b2006-08-04 04:50:21 +000059- Bug #1531405, format_exception no longer raises an exception if
60 str(exception) raised an exception.
61
Neil Schemenauer06ded092006-08-04 16:20:30 +000062- Fix a bug in the ``compiler`` package that caused invalid code to be
63 generated for nested functions.
64
Neal Norwitzff4b63b2006-08-04 04:50:21 +000065
66Extension Modules
67-----------------
68
Bob Ippolitoe6c9f982006-08-04 23:59:21 +000069- Bug #1530559, struct.pack raises TypeError where it used to convert.
70 Passing float arguments to struct.pack when integers are expected
71 now triggers a DeprecationWarning.
72
Neal Norwitzff4b63b2006-08-04 04:50:21 +000073
74Tests
75-----
76

80
Andrew MacIntyre16ee33a2006-08-06 12:37:03 +000081- test_threading now skips testing alternate thread stack sizes on
82 platforms that don't support changing thread stack size.
83
Neal Norwitzff4b63b2006-08-04 04:50:21 +000084
Georg Brandl212b5872006-08-05 06:10:54 +000085Documentation

100-----
101
102- Bug #1069160. Internal correctness changes were made to
103 ``PyThreadState_SetAsyncExc()``. A test case was added, and
104 the documentation was changed to state that the return value
105 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000112What's New in Python 2.5 beta 3?
113================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000114
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000115*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000116
117Core and builtins
118-----------------
119
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000120- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t, it previously
121 returned a long (see PEP 353).
122
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000123- Bug #1515471: string.replace() accepts character buffers again.
124
Neal Norwitz07aadb12006-07-30 06:55:48 +0000125- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
126 This provides the proper warning for struct.pack().
127 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
128
Neal Norwitz0d62a062006-07-30 06:53:31 +0000129- Patch #1531113: Fix augmented assignment with yield expressions.
130 Also fix a SystemError when trying to assign to yield expressions.
131
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000132- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
133 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
134 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
135 excessive filesystem operations during imports.
136
Tim Petersbc24eee2006-07-27 01:14:53 +0000137- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
138 operations on signed longs that are formally undefined by C.
139 Unfortunately, at least one compiler now cares about that, so complicated
140 the code to make that compiler happy again.
141
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000142- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
143
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000144- Patch #1232023: Stop including current directory in search
145 path on Windows.
146
Neal Norwitze1fdb322006-07-21 05:32:28 +0000147- Fix some potential crashes found with failmalloc.
148
Neal Norwitze7563102006-07-17 01:00:16 +0000149- Fix warnings reported by Klocwork's static analysis tool.
150
Neal Norwitz84be93b2006-07-16 01:50:38 +0000151- Bug #1512814, Fix incorrect lineno's when code within a function
152 had more than 255 blank lines.
153
Georg Brandl9dceedb2006-07-12 15:31:17 +0000154- Patch #1521179: Python now accepts the standard options ``--help`` and
155 ``--version`` as well as ``/?`` on Windows.
156
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000157- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000158 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000159 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000160
Tim Peters112aad32006-07-19 00:03:19 +0000161- Bug #1524317: Compiling Python ``--without-threads`` failed.
162 The Python core compiles again then, and, in a build without threads, the
163 new ``sys._current_frames()`` returns a dictionary with one entry,
164 mapping the faux "thread id" 0 to the current frame.
165
Ronald Oussoren3075e162006-07-25 20:28:55 +0000166- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000167
Ronald Oussoren3075e162006-07-25 20:28:55 +0000168
Neal Norwitza1f10902006-07-12 07:28:29 +0000169Library
170-------
171
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000172- Correction of patch #1455898: In the mbcs decoder, set final=False
173 for stream decoder, but final=True for the decode function.
174
Georg Brandl07fec3a2006-08-01 18:49:24 +0000175- os.urandom no longer masks unrelated exceptions like SystemExit or
176 KeyboardInterrupt.
177
Tim Peters4643c2f2006-08-10 22:45:34 +0000178- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000179 shutil.copytree on Windows
180
Georg Brandle34ac7c2006-07-30 11:07:23 +0000181- Bug #1002398: The documentation for os.path.sameopenfile now correctly
182 refers to file descriptors, not file objects.
183
Fred Drakefbdeaad2006-07-29 16:56:15 +0000184- Rename of the xml package to xmlcore, and the import hackery done to
185 make it appear at both names, has been removed. Bug #1511497,
186 #1513611, and probably others.
187
Georg Brandledd9b0d2006-07-29 09:33:26 +0000188- Bug #1441397: The compiler module now recognizes module and function
189 docstrings correctly as it did in Python 2.4.
190
Tim Peters6f681472006-07-27 23:44:37 +0000191- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
192 lost that tests are sorted by name before being run. This rarely
193 matters for well-written tests, but can create baffling symptoms if
194 side effects from one test to the next affect outcomes. ``DocTestFinder``
195 has been changed to sort the list of tests it returns.
196
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000197- The distutils version has been changed to 2.5.0, and are now kept
198 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000199
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000200- Bug #978833: Really close underlying socket in _socketobject.close.
201
Georg Brandl0619a322006-07-26 07:40:17 +0000202- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
203 with title().
204
Georg Brandlcf0c1722006-07-26 07:23:32 +0000205- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
206 to recursive calls and call it with the failing package name.
207
Martin v. Löwis0b483032006-07-25 09:53:12 +0000208- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
209
Georg Brandlc13c34c2006-07-24 14:09:56 +0000210- Patch #1515343: Fix printing of deprecated string exceptions with a
211 value in the traceback module.
212
Greg Ward48fae7a2006-07-23 16:05:51 +0000213- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
214
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000215- Patch #1524429: Use repr() instead of backticks in Tkinter again.
216
Brett Cannoncaebe222006-07-18 04:41:36 +0000217- Bug #1520914: Change time.strftime() to accept a zero for any position in its
218 argument tuple. For arguments where zero is illegal, the value is forced to
219 the minimum value that is correct. This is to support an undocumented but
220 common way people used to fill in inconsequential information in the time
221 tuple pre-2.4.
222
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000223- Patch #1220874: Update the binhex module for Mach-O.
224
Barry Warsawb110bad2006-07-21 14:51:07 +0000225- The email package has improved RFC 2231 support, specifically for
226 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
227 (name*0=<blah>) parameter continuations. This may change the types of
228 values returned from email.message.Message.get_param() and friends.
229 Specifically in some cases where non-encoded continuations were used,
230 get_param() used to return a 3-tuple of (None, None, string) whereas now it
231 will just return the string (since non-encoded continuations don't have
232 charset and language parts).
233
234 Also, whereas % values were decoded in all parameter continuations, they are
235 now only decoded in encoded parameter parts.
236
Ronald Oussoren3075e162006-07-25 20:28:55 +0000237- Bug #1517990: IDLE keybindings on MacOS X now work correctly
238
239- Bug #1517996: IDLE now longer shows the default Tk menu when a
240 path browser, class browser or debugger is the frontmost window on MacOS X
241
Barry Warsaw00decd72006-07-27 23:43:15 +0000242- Patch #1520294: Support for getset and member descriptors in types.py,
243 inspect.py, and pydoc.py. Specifically, this allows for querying the type
244 of an object against these built-in types and more importantly, for getting
245 their docstrings printed in the interactive interpreter's help() function.
246
Ronald Oussoren3075e162006-07-25 20:28:55 +0000247
Neal Norwitza1f10902006-07-12 07:28:29 +0000248Extension Modules
249-----------------
250
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000251- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
252 a socket operation on a socket with a timeout, the exception will be
253 caught correctly. Previously, the exception was not caught.
254
Thomas Heller1393d6a2006-07-28 21:43:20 +0000255- Patch #1529514: The _ctypes extension is now compiled on more
256 openbsd target platforms.
257
Tim Peters9cab5932006-07-28 00:30:00 +0000258- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
259 a memory leak, affecting pickles and deep copies.
260
Tim Petersbc24eee2006-07-27 01:14:53 +0000261- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

263
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000264- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
265
Thomas Hellerce049a02006-07-14 17:51:14 +0000266- Patch #1521817: Index range checking on ctypes arrays containing
267 exactly one element enabled again. This allows iterating over these
268 arrays, without the need to check the array size before.
269
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000270- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000271 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000272 /dev/null in certain cases; this is now fixed.
273
Thomas Heller47d7a062006-07-12 08:43:47 +0000274- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
275 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000276
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000277- Because of a misspelled preprocessor symbol, ctypes was always
278 compiled without thread support; this is now fixed.
279
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000280- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
281 methods now allow their database parameter to be None as the
282 sleepycat API allows.
283
Matt Flemingec926502006-07-28 11:27:27 +0000284- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
285 bluetooth API compared with Linux and FreeBSD.
286
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000287Tests
288-----
289
290- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
291 how long the test file should take to play. Now accepts taking 2.93 secs
292 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
293
Georg Brandl4793aa32006-07-28 18:31:39 +0000294- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
295 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
296 run via ``regrtest.py``. Now they do.

301- Bug #1439538: Drop usage of test -e in configure as it is not portable.
302
Ronald Oussoren26cad082006-08-01 21:00:57 +0000303Mac
304---
305
306- PythonLauncher now works correctly when the path to the script contains
307 characters that are treated specially by the shell (such as quotes).
308
309- Bug #1527397: PythonLauncher now launches scripts with the working directory
310 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000311 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000312 expect.

320Core and builtins
321-----------------
322
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000323- Bug #1441486: The literal representation of -(sys.maxint - 1)
324 again evaluates to a int object, not a long.
325
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000326- Bug #1501934: The scope of global variables that are locally assigned
327 using augmented assignment is now correctly determined.
328
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000329- Bug #927248: Recursive method-wrapper objects can now safely
330 be released.
331
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000332- Bug #1417699: Reject locale-specific decimal point in float()
333 and atof().
334
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000335- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
336 omit a default "error" argument for NULL pointer. This allows
337 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000338
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000339- Bug #1519018: 'as' is now validated properly in import statements.
340
Neal Norwitz28746ab2006-07-09 22:14:42 +0000341- On 64 bit systems, int literals that use less than 64 bits are
342 now ints rather than longs.
343
Neal Norwitzed657552006-07-10 00:04:44 +0000344- Bug #1512814, Fix incorrect lineno's when code at module scope
345 started after line 256.
346
Tim Peters32a83612006-07-10 21:08:24 +0000347- New function ``sys._current_frames()`` returns a dict mapping thread
348 id to topmost thread stack frame. This is for expert use, and is
349 especially useful for debugging application deadlocks. The functionality
350 was previously available in Fazal Majid's ``threadframe`` extension
351 module, but it wasn't possible to do this in a wholly threadsafe way from
352 an extension.

355-------
356
Martin v. Löwis77621582006-07-30 13:27:31 +0000357- Bug #1257728: Mention Cygwin in distutils error message about a missing
358 VS 2003.
359
Martin v. Löwis06c68b82006-07-10 22:11:28 +0000360- Patch #1519566: Update turtle demo, make begin_fill idempotent.
361
Tim Peters32a83612006-07-10 21:08:24 +0000362- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000363 environment variable to be set in order to the SDK environment
364 for finding the compiler, include files, etc.
365
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000366- Bug #1515998: Properly generate logical ids for files in bdist_msi.

Nick Coghlan2d792252006-07-06 13:47:18 +0000368- warnings.py now ignores ImportWarning by default
369
Thomas Woutersadd19112006-07-05 11:03:49 +0000370- string.Template() now correctly handles tuple-values. Previously,
371 multi-value tuples would raise an exception and single-value tuples would
372 be treated as the value they contain, instead.
373
Martin v. Löwisede77f52006-07-03 13:01:35 +0000374- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
375 even if some data are received.

381 degrees and radians.
382
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000383- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000384 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000385
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000386- Bug #1514703: Only setup canvas window in turtle when the canvas
387 is created.
388
Martin v. Löwis7596e832006-07-01 15:33:37 +0000389- Bug #1513223: .close() of a _socketobj now releases the underlying
390 socket again, which then gets closed as it becomes unreferenced.
391
Fred Drake10497c82006-06-29 02:57:48 +0000392- Bug #1504333: Make sgmllib support angle brackets in quoted
393 attribute values.
394
395- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
396 sgmllib ('[' and ']' were not accepted).
397
Georg Brandl1be63af2006-06-28 20:23:25 +0000398- Fix a bug in the turtle module's end_fill function.
399
Brett Cannon53ab5b72006-06-22 16:49:14 +0000400- Bug #1510580: The 'warnings' module improperly required that a Warning
401 category be either a types.ClassType and a subclass of Warning. The proper
402 check is just that it is a subclass with Warning as the documentation states.
403
Georg Brandlad29e632006-06-21 17:45:17 +0000404- The compiler module now correctly compiles the new try-except-finally
405 statement (bug #1509132).
406
Neal Norwitz60373cd2006-06-22 06:30:50 +0000407- The wsgiref package is now installed properly on Unix.
408
Vinay Sajip28e57612006-07-01 10:45:20 +0000409- A bug was fixed in logging.config.fileConfig() which caused a crash on
410 shutdown when fileConfig() was called multiple times.
411
Gerhard Häring762fbd32006-07-02 17:48:30 +0000412- The sqlite3 module did cut off data from the SQLite database at the first
413 null character before sending it to a custom converter. This has been fixed
414 now.
415
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000416Extension Modules
417-----------------
418
Tim Peters112aad32006-07-19 00:03:19 +0000419- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
420 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
421 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000422
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000423- Assigning None to pointer type fields in ctypes structures possible
424 overwrote the wrong fields, this is fixed now.
425
426- Fixed a segfault in _ctypes when ctypes.wintypes were imported
427 on non-Windows platforms.
428
429- Bug #1518190: The ctypes.c_void_p constructor now accepts any
430 integer or long, without range checking.
431
432- Patch #1517790: It is now possible to use custom objects in the ctypes
433 foreign function argtypes sequence as long as they provide a from_param
434 method, no longer is it required that the object is a ctypes type.
435
436- The '_ctypes' extension module now works when Python is configured
437 with the --without-threads option.
438
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000439- Bug #1513646: os.access on Windows now correctly determines write
440 access, again.
441
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000442- Bug #1512695: cPickle.loads could crash if it was interrupted with
443 a KeyboardInterrupt.
444
Neal Norwitza12aa882006-07-06 06:45:08 +0000445- Bug #1296433: parsing XML with a non-default encoding and
446 a CharacterDataHandler could crash the interpreter in pyexpat.
447
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000448- Patch #1516912: improve Modules support for OpenVMS.
449
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000450Build
451-----
452
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000453- Automate Windows build process for the Win64 SSL module.
454
Tim Peters32a83612006-07-10 21:08:24 +0000455- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000456 Previously, the slight difference could cause compilation errors of the
457 'zlib' module on systems with more than one version of zlib.
458
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000459- The MSI compileall step was fixed to also support a TARGETDIR
460 with spaces in it.
461
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000462- Bug #1517388: sqlite3.dll is now installed on Windows independent
463 of Tcl/Tk.
464
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000465- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000466 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +0000468Tests
469-----
470
471- Call os.waitpid() at the end of tests that spawn child processes in order
472 to minimize resources (zombies).
473
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000474Documentation
475-------------
476
Nick Coghlan2d792252006-07-06 13:47:18 +0000477- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
478 documentation for the warnings module.
479
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000480- Patch #1509163: MS Toolkit Compiler no longer available.
481
Neal Norwitz56640df2006-07-10 02:36:41 +0000482- Patch #1504046: Add documentation for xml.etree.

490Core and builtins
491-----------------
492
Georg Brandla56b9152006-06-19 06:35:54 +0000493- Patch #1507676: Error messages returned by invalid abstract object operations
494 (such as iterating over an integer) have been improved and now include the
495 type of the offending object to help with debugging.
496
Brett Cannonea3912b2006-06-13 21:46:41 +0000497- Bug #992017: A classic class that defined a __coerce__() method that returned
498 its arguments swapped would infinitely recurse and segfault the interpreter.
499
Neal Norwitz909eb122006-06-12 02:13:21 +0000500- Fix the socket tests so they can be run concurrently.
501
Neal Norwitzb9845e72006-06-12 02:11:18 +0000502- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000503 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000504
Brett Cannon22565aa2006-06-09 22:31:23 +0000505- Bug #532646: object.__call__() will continue looking for the __call__
506 attribute on objects until one without one is found. This leads to recursion
507 when you take a class and set its __call__ attribute to an instance of the
508 class. Originally fixed for classic classes, but this fix is for new-style.
509 Removes the infinite_rec_3 crasher.
510
Georg Brandl24250812006-06-09 18:45:48 +0000511- The string and unicode methods startswith() and endswith() now accept
512 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
513
Brett Cannonde3b0522006-06-08 17:00:45 +0000514- Buffer objects, at the C level, never used the char buffer
515 implementation even when the char buffer for the wrapped object was
516 explicitly requested (originally returned the read or write buffer).
517 Now a TypeError is raised if the char buffer is not present but is
518 requested.
519
Georg Brandlddbaa662006-06-04 21:56:52 +0000520- Patch #1346214: Statements like "if 0: suite" are now again optimized
521 away like they were in Python 2.4.
522
Georg Brandlb7c8f542006-05-27 12:30:25 +0000523- Builtin exceptions are now full-blown new-style classes instead of
524 instances pretending to be classes, which speeds up exception handling
525 by about 80% in comparison to 2.5a2.
526
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000527- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
528 Unicode 4.1.
529
Georg Brandlf4ef1162006-05-26 18:03:31 +0000530- Patch #921466: sys.path_importer_cache is now used to cache valid and
531 invalid file paths for the built-in import machinery which leads to
532 fewer open calls on startup.
533
Tim Peters696cf432006-05-24 21:10:40 +0000534- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
535 of-2 bases. The largest speedup is for inputs with about 1000 decimal
536 digits. Conversion from non-power-of-2 bases remains quadratic-time in
537 the number of input digits (it was and remains linear-time for bases
538 2, 4, 8, 16 and 32).
539
Tim Petersb713ec22006-05-23 18:45:30 +0000540- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
541 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
542 an integer close to ``sys.maxint``. This was repaired by patch
543 #1335972, which also gives a nice speedup.
544
Richard Jonescebbefc2006-05-23 18:28:17 +0000545- Patch #1337051: reduced size of frame objects.
546
547- PyErr_NewException now accepts a tuple of base classes as its
548 "base" parameter.
549
Richard Jones7c88dcc2006-05-23 10:37:38 +0000550- Patch #876206: function call speedup by retaining allocated frame
551 objects.
552
Georg Brandl7b90e162006-05-18 07:01:27 +0000553- Bug #1462152: file() now checks more thoroughly for invalid mode
554 strings and removes a possible "U" before passing the mode to the
555 C library function.
556
Neal Norwitz1004a532006-05-15 07:17:23 +0000557- Patch #1488312, Fix memory alignment problem on SPARC in unicode
558
Neal Norwitz373f0a72006-05-15 07:04:36 +0000559- Bug #1487966: Fix SystemError with conditional expression in assignment
560
Martin v. Löwis879768d2006-05-11 13:28:43 +0000561- WindowsError now has two error code attributes: errno, which carries
562 the error values from errno.h, and winerror, which carries the error
563 values from winerror.h. Previous versions put the winerror.h values
564 (from GetLastError()) into the errno attribute.
565
Martin v. Löwis77736712006-05-04 05:51:03 +0000566- Patch #1475845: Raise IndentationError for unexpected indent.
567
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000568- Patch #1479181: split open() and file() from being aliases for each other.
569
Tim Peters44bd9862006-06-01 13:49:23 +0000570- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
571 methods were always silently ignored by dictionaries when comparing keys.
572 They are now passed through (except when using the C API function
573 ``PyDict_GetItem()``, whose semantics did not change).
574
575- Bug #1456209: In some obscure cases it was possible for a class with a
576 custom ``__eq__()`` method to confuse dict internals when class instances
577 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
578 No, you don't have any code that did this ;-)

586
Brett Cannon6ee7d012006-06-08 16:23:04 +0000587- Change binascii.hexlify to accept a read-only buffer instead of only a char
588 buffer and actually follow its documentation.
589
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000590- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
591
Nick Coghlanc649ec52006-05-29 12:43:05 +0000592- Patch #1478788 (modified version): The functional extension module has
593 been renamed to _functools and a functools Python wrapper module added.
594 This provides a home for additional function related utilities that are
595 not specifically about functional programming. See PEP 309.
596
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000597- Patch #1493701: performance enhancements for struct module.

605 enabled builds on Windows and systems with Posix threads support.
606
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000607- On Win32, os.listdir now supports arbitrarily-long Unicode path names
608 (up to the system limit of 32K characters).
609
610- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
611 As a result, these functions now raise WindowsError instead of OSError.
612
Tim Peters7a822da2006-05-25 21:50:17 +0000613- ``time.clock()`` on Win64 should use the high-performance Windows
614 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
615 Windows platforms).
616
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000617- Calling Tk_Init twice is refused if the first call failed as that
618 may deadlock.
619
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000620- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
621 accept it without potentially using an uninitialized pointer.
622
623- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
624 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smith372b5832006-06-05 18:48:21 +0000627- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000628 [pybsddb project SF patch number 1466734]
629
Gregory P. Smith372b5832006-06-05 18:48:21 +0000630- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
631 parameter is supplied. [SF pybsddb bug #1477863]
632
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000633- bsddb: the __len__ method of a DB object has been fixed to return correct
634 results. It could previously incorrectly return 0 in some cases.
635 Fixes SF bug 1493322 (pybsddb bug 1184012).
636
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000637- bsddb: the bsddb.dbtables Modify method now raises the proper error and
638 aborts the db transaction safely when a modifier callback fails.
639 Fixes SF python patch/bug #1408584.
640
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000641- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000642 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000643 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
644 database calls that would previously deadlock. [SF python bug #775414]
645
Vinay Sajip28e57612006-07-01 10:45:20 +0000646- Patch #1446489: add support for the ZIP64 extensions to zipfile.

668 mime.types file for determining MIME types.
669
Georg Brandl2605ca82006-06-14 06:08:31 +0000670- Bug #1339007: Shelf objects now don't raise an exception in their
671 __del__ method when initialization failed.
672
Martin v. Löwisd8251432006-06-14 05:21:04 +0000673- Patch #1455898: The MBCS codec now supports the incremental mode for
674 double-byte encodings.
675
Tim Peters43898b42006-06-14 04:09:25 +0000676- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
677 guarantee that adjacent triples in the return list always describe
678 non-adjacent blocks. Previously, a pair of matching blocks could end
679 up being described by multiple adjacent triples that formed a partition
680 of the matching pair.
681
Greg Ward0e0c9f42006-06-11 16:24:11 +0000682- Bug #1498146: fix optparse to handle Unicode strings in option help,
683 description, and epilog.
684
Greg Wardd1c797e2006-06-11 14:42:41 +0000685- Bug #1366250: minor optparse documentation error.

Greg Ward7f547402006-06-11 00:40:49 +0000687- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
688 clarify docs.
689
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000690- The wsgiref package has been added to the standard library.
691
Nick Coghlan676725d2006-06-08 13:54:49 +0000692- The functions update_wrapper() and wraps() have been added to the functools
693 module. These make it easier to copy relevant metadata from the original
694 function when writing wrapper functions.
695
Tim Petersd6a9eef2006-06-05 01:48:21 +0000696- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
697 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000698
Martin v. Löwis3f767792006-06-04 19:36:28 +0000699- Patch #1359618: Speed up charmap encoder by using a trie structure
700 for lookup.
701
Tim Petersd609b1a2006-06-02 23:22:51 +0000702- The functions in the ``pprint`` module now sort dictionaries by key
703 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
704 if and only if its display required more than one line, although that
705 wasn't documented. The new behavior increases predictability; e.g.,
706 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
707
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000708- Patch #1497027: try HTTP digest auth before basic auth in urllib2

717
Georg Brandlb89316f2006-05-17 15:51:16 +0000718- Patch #1180296: Two new functions were added to the locale module:
719 format_string() to get the effect of "format % items" but locale-aware,
720 and currency() to format a monetary number with currency sign.
721
Georg Brandle3a25832006-05-17 14:56:04 +0000722- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
723 and several features added, such as speed and geometry control.
724
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000725- Patch #1488881: add support for external file objects in bz2 compressed
726 tarfiles.
727
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000728- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
729 stdout arguments, making it possible to redirect input and output
730 for remote debugging.
731
732- Patch #1484695: Update the tarfile module to version 0.8. This fixes
733 a couple of issues, notably handling of long file names using the
734 GNU LONGNAME extension.
735
736- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
737 new flag when ``name`` is already the name of an option flag.
738
739- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
740 package.
741
742- Patch #1472854: make the rlcompleter.Completer class usable on non-
743 UNIX platforms.
744
745- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
746
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000747- Bug #1472827: correctly escape newlines and tabs in attribute values in

780
781*Release date: 27-APR-2006*
782
783Core and builtins
784-----------------
785
Thomas Heller1b046642006-04-18 18:51:06 +0000786- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
787 by converting these apis from macros into exported functions again:
788
789 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
790 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
791 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
792 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
793 PyRun_String Py_CompileString
794
Martin v. Löwis45294a92006-04-18 06:24:08 +0000795- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
796
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000797- All uses of PyStructSequence_InitType have been changed to initialize
798 the type objects only once, even if the interpreter is initialized
799 multiple times.
800
Neal Norwitz61546162006-04-14 05:20:28 +0000801- Bug #1454485, array.array('u') could crash the interpreter. This was
802 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
803 to unicode when it didn't make sense. 'u#' now requires a unicode string.
804
805- Py_UNICODE is unsigned. It was always documented as unsigned, but
806 due to a bug had a signed value in previous versions.
807
Tim Peters3a5e8b12006-04-11 01:44:07 +0000808- Patch #837242: ``id()`` of any Python object always gives a positive
809 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
810 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000811 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000812 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000813
Tim Peters3a5e8b12006-04-11 01:44:07 +0000814 def __hash__(self):
815 return id(self) # WRONG
816
817 because a hash result must be a (short) Python int but it was always
818 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000819 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000820 was always usable as a hash value before this patch. That's no longer
821 necessarily so.
822
823- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000824 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000825 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000826 #1454844)
827
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000828- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
829 involving generators that have paused outside of any ``try`` or ``with``
830 blocks. (In 2.5a1, a paused generator that was part of a reference
831 cycle could not be garbage collected, regardless of whether it was
832 paused in a ``try`` or ``with`` block.)

862 abusing errno.
863
Tim Peters711bf302006-04-25 03:31:36 +0000864- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes

869 caught inside exit handlers.
870
Greg Wardab05edc2006-04-23 03:47:58 +0000871- Updated optparse module to Optik 1.5.1 (allow numeric constants in
872 hex, octal, or binary; add ``append_const`` action; keep going if
873 gettext cannot be imported; added ``OptionParser.destroy()`` method;
874 added ``epilog`` for better help generation).
875
Tim Peters21fbd572006-04-21 21:18:10 +0000876- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
877 called from a thread spawned as a side effect of importing a module.
878
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000879- The pydoc module now supports documenting packages contained in
880 .zip or .egg files.
881
882- The pkgutil module now has several new utility functions, such
883 as ``walk_packages()`` to support working with packages that are either
884 in the filesystem or zip files.
885
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000886- The mailbox module can now modify and delete messages from
887 mailboxes, in addition to simply reading them. Thanks to Gregory
888 K. Johnson for writing the code, and to the 2005 Google Summer of
889 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000890
Tim Petersc7605f22006-04-17 21:12:33 +0000891- The ``__del__`` method of class ``local`` in module ``_threading_local``
892 returned before accomplishing any of its intended cleanup.

938 and "%zu" for unsigned integers of type ``size_t``.

941-----
942
Nick Coghlanda2268f2006-04-24 04:37:15 +0000943- test_contextlib now checks contextlib.nested can cope with exceptions
944 being raised and caught inside exit handlers.
945
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000946- test_cmd_line now checks operation of the -m and -c command switches
947
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000948- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
949 it separately and by hand. It also wasn't cleaning up its changes to
950 the current Decimal context.
951
Thomas Woutersabd08882006-04-26 15:53:30 +0000952- regrtest.py now has a -M option to run tests that test the new limits of
953 containers, on 64-bit architectures. Running these tests is only sensible
954 on 64-bit machines with more than two gigabytes of memory. The argument
955 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000963Documentation
964-------------
965
Tim Petersb06d28c2006-05-12 01:57:59 +0000966- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
967
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000968- PEP 343: Added Context Types section to the library reference
969 and attempted to bring other PEP 343 related documentation into
970 line with the implementation and/or python-dev discussions.
971
Tim Peters8dc73d22006-04-24 02:03:16 +0000972- Bug #1337990: clarified that ``doctest`` does not support examples
973 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000976What's New in Python 2.5 alpha 1?
977=================================
978
Anthony Baxterebed3f62006-04-03 15:03:44 +0000979*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000980
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000981Core and builtins
982-----------------
983
Nick Coghlan43832302006-04-23 17:04:07 +0000984- PEP 338: -m command line switch now delegates to runpy.run_module
985 allowing it to support modules in packages and zipfiles
986
Martin v. Löwisc661b882006-04-20 04:54:23 +0000987- On Windows, .DLL is not an accepted file name extension for
988 extension modules anymore; extensions are only found if they
989 end in .PYD.
990
Martin v. Löwisea62d252006-04-03 10:56:49 +0000991- Bug #1421664: sys.stderr.encoding is now set to the same value as
992 sys.stdout.encoding.
993
Neal Norwitz92e212f2006-04-03 04:48:37 +0000994- __import__ accepts keyword arguments.
995
Georg Brandlccadf842006-03-31 18:54:53 +0000996- Patch #1460496: round() now accepts keyword arguments.
997
Anthony Baxter262c00a2006-03-30 10:53:17 +0000998- Fixed bug #1459029 - unicode reprs were double-escaped.
999
Hye-Shik Changd478f342006-03-23 12:32:36 +00001000- Patch #1396919: The system scope threads are reenabled on FreeBSD
1001 5.4 and later versions.
1002
Neal Norwitze98ccf62006-03-23 05:39:47 +00001003- Bug #1115379: Compiling a Unicode string with an encoding declaration
1004 now gives a SyntaxError.
1005
Georg Brandlabd1ff82006-03-18 07:59:59 +00001006- Previously, Python code had no easy way to access the contents of a
1007 cell object. Now, a ``cell_contents`` attribute has been added
1008 (closes patch #1170323).
1009
Tim Peterscf79aac2006-03-16 01:14:46 +00001010- Patch #1123430: Python's small-object allocator now returns an arena to
1011 the system ``free()`` when all memory within an arena becomes unused
1012 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1013 freed. Some applications will see a drop in virtual memory size now,
1014 especially long-running applications that, from time to time, temporarily
1015 use a large number of small objects. Note that when Python returns an
1016 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001017 platform C library will in turn return that memory to the operating system.
1018 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001019 appears to be effective at least on Microsoft C and gcc-based systems.
1020 Thanks to Evan Jones for hard work and patience.
1021
Georg Brandl533ff6f2006-03-08 18:09:27 +00001022- Patch #1434038: property() now uses the getter's docstring if there is
1023 no "doc" argument given. This makes it possible to legitimately use
1024 property() as a decorator to produce a read-only property.
1025
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001026- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1027 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1028 of requiring an int or long in slicing and a few other contexts, enabling
1029 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1030
Neal Norwitz995acdf2006-03-07 05:01:00 +00001031- Fixed various bugs reported by Coverity's Prevent tool.
1032
Brett Cannonbf364092006-03-01 04:25:17 +00001033- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1034 new exception base class, BaseException, which has a new message attribute.
1035 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1036 Raising a string exception now raises a DeprecationWarning.
1037
Thomas Woutersfb609f42006-02-28 16:37:25 +00001038- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1039 explicitly relative, using 'from .module import name' to mean 'from the same
1040 package as this module is in. Imports without dots still default to the
1041 old relative-then-absolute, unless 'from __future__ import
1042 absolute_import' is used.
1043
Brett Cannona7446e32006-02-27 23:39:10 +00001044- Properly check if 'warnings' raises an exception (usually when a filter set
1045 to "error" is triggered) when raising a warning for raising string
1046 exceptions.
1047
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001048- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001049 The name was removed from Include/code.h.
1050
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001051- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001052
Guido van Rossum1968ad32006-02-25 22:38:04 +00001053- Patch 1433928:
1054 - The copy module now "copies" function objects (as atomic objects).
1055 - dict.__getitem__ now looks for a __missing__ hook before raising
1056 KeyError.
1057
Tim Peters84ef21c2006-02-28 20:39:06 +00001058- PEP 343: with statement implemented. Needs ``from __future__ import
1059 with_statement``. Use of 'with' as a variable will generate a warning.
1060 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001061 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001062 The following objects have __context__ methods:
1063 - The built-in file type.
1064 - The thread.LockType type.
1065 - The following types defined by the threading module:
1066 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1067 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001068
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001069- Fix the encodings package codec search function to only search
1070 inside its own package. Fixes problem reported in patch #1433198.
1071
1072 Note: Codec packages should implement and register their own
1073 codec search function. PEP 100 has the details.
1074
Tim Peters9ea89d22006-06-04 03:26:02 +00001075- PEP 353: Using ``Py_ssize_t`` as the index type.
1076
1077- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1078 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1079 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1080 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1081 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001082
Neal Norwitzfc76d632006-01-10 06:03:13 +00001083- Patch #1400181, fix unicode string formatting to not use the locale.
1084 This is how string objects work. u'%f' could use , instead of .
1085 for the decimal point. Now both strings and unicode always use periods.
1086
Neal Norwitz671b9e32006-01-09 07:07:12 +00001087- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1088 configure would break checking curses.h.
1089
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001090- Bug #959576: The pwd module is now builtin. This allows Python to be
1091 built on UNIX platforms without $HOME set.
1092
Neal Norwitzc10978f2005-12-19 06:07:16 +00001093- Bug #1072182, fix some potential problems if characters are signed.
1094
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001095- Bug #889500, fix line number on SyntaxWarning for global declarations.
1096
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001097- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1098
Neal Norwitze7214a12005-12-18 05:03:17 +00001099- Support for converting hex strings to floats no longer works.
1100 This was not portable. float('0x3') now raises a ValueError.
1101
Barry Warsaw2a38a862005-12-18 01:27:35 +00001102- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001103 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001104 is now displayed in interactive prompt banner.
1105
Georg Brandlfa166682005-12-17 21:45:17 +00001106- Implementation of PEP 341 - Unification of try/except and try/finally.
1107 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001108 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001109
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001110- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1111 now encodes backslash correctly.
1112
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001113- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1114
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001115- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001116 and long longs.
1117
Neal Norwitz67715f02005-11-09 06:59:35 +00001118- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001119 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001120 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001121
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001122- Replaced most Unicode charmap codecs with new ones using the
1123 new Unicode translate string feature in the builtin charmap
1124 codec; the codecs were created from the mapping tables available
1125 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1126 encodings now include a mapping for the Apple logo)
1127
Tim Peterse3547fd2005-12-16 23:13:57 +00001128- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001129
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001130- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001131
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001132- A new AST parser implementation was completed. The abstract
1133 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001134 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001135
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001136- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001137 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1138
Neal Norwitz708e51a2005-10-03 04:48:15 +00001139- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1140
Neal Norwitz11bd1192005-10-03 00:54:56 +00001141- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1142 Provide a warning when a directory is passed on the command line.
1143
Neal Norwitz40d37812005-10-02 01:48:49 +00001144- Fix segfault with invalid coding.
1145
1146- SF bug #772896: unknown encoding results in MemoryError.
1147
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001148- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001149 supported a __len__() method which evaluated to False when the iterator
1150 was empty.
1151
Guido van Rossum630db602005-09-20 18:49:54 +00001152- On 64-bit platforms, when __len__() returns a value that cannot be
1153 represented as a C int, raise OverflowError.
1154
Skip Montanarof8948ca2005-09-19 03:54:46 +00001155- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001156 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001157
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001158- SF bug #893549: parsing keyword arguments was broken with a few format
1159 codes.
1160
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001161- Changes donated by Elemental Security to make it work on AIX 5.3
1162 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1163 bug #105470: test_pwd fails on 64bit system (Opteron).
1164
Guido van Rossum539c6622005-09-14 17:49:54 +00001165- Changes donated by Elemental Security to make it work on HP-UX 11 on
1166 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1167
Georg Brandl4550b8d2005-08-26 06:43:52 +00001168- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001169 (fixes bug #1119418).
1170
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001171- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1172
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001173- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1174 exceptions that cause a function to exit.
1175
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001176- The implementation of set() and frozenset() was revised to use its
1177 own internal data structure. Memory consumption is reduced by 1/3
1178 and there are modest speed-ups as well. The API is unchanged.
1179
Tim Petersde7990b2005-07-17 23:45:23 +00001180- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1181
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001182- SF bug #1229429: PyObject_CallMethod failed to decrement some
1183 reference counts in some error exit cases.
1184
Tim Petersecc6e6a2005-07-10 22:30:55 +00001185- SF bug #1185883: Python's small-object memory allocator took over
1186 a block managed by the platform C library whenever a realloc specified
1187 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001188 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001189 portable way to copy data from the C-managed block into Python's
1190 small-object space without risking a memory fault. Python's small-object
1191 realloc now leaves such blocks under the control of the platform C
1192 realloc.
1193
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001194- SF bug #1232517: An overflow error was not detected properly when
1195 attempting to convert a large float to an int in os.utime().
1196
Raymond Hettinger3296e692005-06-29 23:29:56 +00001197- SF bug #1224347: hex longs now print with lowercase letters just
1198 like their int counterparts.
1199
Michael W. Hudson188d4362005-06-20 16:52:57 +00001200- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1201 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1202 interpreter states; back out that fix and do a better job (see
1203 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1204 for a longer write-up of the problem).
1205
Michael W. Hudsondf888462005-06-03 14:41:55 +00001206- SF patch #1180995: marshal now uses a binary format by default when
1207 serializing floats.
1208
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001209- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1210 the routines that promise to produce IEEE 754 binary representations
1211 of floats now simply copy bytes around.
1212
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001213- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1214 278.
1215
Brett Cannonc3647ac2005-04-26 03:45:26 +00001216- patch #1109424: int, long, float, complex, and unicode now check for the
1217 proper magic slot for type conversions when subclassed. Previously the
1218 magic slot was ignored during conversion. Semantics now match the way
1219 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001220 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001221 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001222 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001223
Barry Warsawc8d907c2005-04-19 23:43:40 +00001224- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1225 NULL, now raise an AttributeError when attempting to set or delete the
1226 attribute. Previously a TypeError was raised, but this was inconsistent
1227 with the equivalent pure-Python implementation.
1228
Michael W. Hudson774479c2005-04-18 08:46:17 +00001229- It is now safe to call PyGILState_Release() before
1230 PyEval_InitThreads() (note that if there is reason to believe there
1231 are multiple threads around you still must call PyEval_InitThreads()
1232 before using the Python API; this fix is for extension modules that
1233 have no way of knowing if Python is multi-threaded yet).
1234
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001235- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1236 disabled caused a crash.
1237
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001238- Bug #1165306: instancemethod_new allowed the creation of a method
1239 with im_class == im_self == NULL, which caused a crash when called.
1240
Tim Petersecc6e6a2005-07-10 22:30:55 +00001241- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001242 fixes the crash seen in bug #1165761
1243
Raymond Hettinger96229b12005-03-11 06:49:40 +00001244- Added two new builtins, any() and all().
1245
Brett Cannon409d8f22005-03-05 06:47:57 +00001246- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001247 (e.g., ``class C(): pass`` is no longer a syntax error).
1248 Patch #1176012 added support to the 'parser' module and 'compiler' package
1249 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001250
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001251- Patch #1115086: Support PY_LONGLONG in structmember.
1252
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001253- Bug #1155938: new style classes did not check that __init__() was
1254 returning None.
1255
Tim Petersecc6e6a2005-07-10 22:30:55 +00001256- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001257 ('\') with a specific error message.
1258
Martin v. Löwisff232d72005-03-03 09:24:38 +00001259- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1260
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001261- Bug #1124295: the __name__ attribute of file objects was
1262 inadvertently made inaccessible in restricted mode.
1263
Tim Petersecc6e6a2005-07-10 22:30:55 +00001264- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001265 an ferror() call.
1266
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001267- min() and max() now support key= arguments with the same meaning as in
1268 list.sort().
1269
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001270- The peephole optimizer now performs simple constant folding in expressions:
1271 (2+3) --> (5).
1272
Raymond Hettingera422c342005-01-11 03:03:27 +00001273- set and frozenset objects can now be marshalled. SF #1098985.
1274
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001275- Bug #1077106: Poor argument checking could cause memory corruption
1276 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001277
Jeremy Hyltonab630502005-02-04 18:44:06 +00001278- The parser did not complain about future statements in illegal
1279 positions. It once again reports a syntax error if a future
1280 statement occurs after anything other than a doc string.
1281
Neil Schemenauercf52c072005-08-12 17:34:58 +00001282- Change the %s format specifier for str objects so that it returns a
1283 unicode instance if the argument is not an instance of basestring and
1284 calling __str__ on the argument returns a unicode instance.
1285
Tim Petersf4e69282006-02-27 17:15:31 +00001286- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1287 current thread state when the auto-GIL-state machinery knows about
1288 it (since the thread state is being deleted, continuing to remember it
1289 can't help, but can hurt if another thread happens to get created with
1290 the same thread id).
1291

1320 for applications that require this specific version (such as IDNA).
1321
Neal Norwitzb62c4332006-03-04 18:35:47 +00001322- The timing module is no longer built by default. It was deprecated

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001482- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1483 been renamed to have only a single underscore prefix. This was done to
1484 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001485
Nick Coghlan43832302006-04-23 17:04:07 +00001486- PEP 338: new module runpy defines a run_module function to support
1487 executing modules which provide access to source code or a code object
1488 via the PEP 302 import mechanisms.
1489
Anthony Baxter93f5b932006-04-03 08:05:07 +00001490- The email module's parsedate_tz function now sets the daylight savings
1491 flag to -1 (unknown) since it can't tell from the date whether it should

1498 in attribute values.
1499
Anthony Baxterc51ee692006-04-01 00:57:31 +00001500- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001501 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001502 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001503 module will not be built.
1504
Tim Petersc17976e2006-04-01 00:26:53 +00001505- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1506 aren't officially supported here, and trying to use them will probably
1507 raise an exception some day. But dicts have been allowed, and "mostly
1508 worked", so support for them won't go away without warning.
1509
Georg Brandl338ef7d2006-03-31 18:42:16 +00001510- Bug #1445068: getpass.getpass() can now be given an explicit stream
1511 argument to specify where to write the prompt.
1512

1520
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001521- Queue.Queue objects now support .task_done() and .join() methods
1522 to make it easier to monitor when daemon threads have completed
1523 processing all enqueued tasks. Patch #1455676.
1524
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001525- popen2.Popen objects now preserve the command in a .cmd attribute.
1526
Thomas Hellerc61c0492006-03-22 10:09:27 +00001527- Added the ctypes ffi package.
1528
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001529- email 4.0 package now integrated. This is largely the same as the email 3.0
1530 package that was included in Python 2.3, except that PEP 8 module names are
1531 now used (e.g. mail.message instead of email.Message). The MIME classes
1532 have been moved to a subpackage (e.g. email.mime.text instead of
1533 email.MIMEText). The old names are still supported for now. Several
1534 deprecated Message methods have been removed and lots of bugs have been
1535 fixed. More details can be found in the email package documentation.
1536
Walter Dörwald40108c92006-03-27 08:15:44 +00001537- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1538 (a subclass of tuple) that provides incremental decoders and encoders
1539 (a way to use stateful codecs without the stream API). Python functions
1540 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1541 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1542 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001543
Walter Dörwald067db482006-03-15 22:17:27 +00001544- Patch #1359365: Calling next() on a closed StringIO.String object raises
1545 a ValueError instead of a StopIteration now (like file and cString.String do).
1546 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1547 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001548
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001549- A regrtest option -w was added to re-run failed tests in verbose mode.

Tim Peterse3547fd2005-12-16 23:13:57 +00001621 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1622 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1623 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1624 Ronald L. Rivest offered this advice for Python:
1625
1626 "The consensus of researchers in this area (at least as
1627 expressed at the NIST Hash Function Workshop 10/31/05),
1628 is that SHA-256 is a good choice for the time being, but
1629 that research should continue, and other alternatives may
1630 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001631
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001632- Added a subset of Fredrik Lundh's ElementTree package. Available

Skip Montanaro174dd222005-05-14 20:54:16 +00001737- Patch #1120353: The xmlrpclib module provides better, more transparent,
1738 support for datetime.{datetime,date,time} objects. With use_datetime set
1739 to True, applications shouldn't have to fiddle with the DateTime wrapper
1740 class at all.
1741
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001742- distutils.commands.upload was added to support uploading distribution
1743 files to PyPI.
1744
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001745- distutils.commands.register now encodes the data as UTF-8 before posting
1746 them to PyPI.
1747
Raymond Hettinger267b8682005-03-27 10:47:39 +00001748- decimal operator and comparison methods now return NotImplemented
1749 instead of raising a TypeError when interacting with other types. This
1750 allows other classes to implement __radd__ style methods and have them
1751 work as expected.
1752
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001753- Bug #1163325: Decimal infinities failed to hash. Attempting to
1754 hash a NaN raised an InvalidOperation instead of a TypeError.
1755
Tim Petersecc6e6a2005-07-10 22:30:55 +00001756- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001757 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1758
Martin v. Löwis00a73e72005-03-04 19:40:34 +00001759- Patch #1043890: Add extractall method to tarfile.
1760
Martin v. Löwisc72dd382005-03-04 13:50:17 +00001761- Patch #1075887: Don't require MSVC in distutils if there is nothing
1762 to build.
1763
Martin v. Löwis637431b2005-03-03 23:12:42 +00001764- Patch #1103407: Properly deal with tarfile iterators when untarring
1765 symbolic links on Windows.
1766
Tim Petersecc6e6a2005-07-10 22:30:55 +00001767- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00001768 profile.py if available.
1769
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001770- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1771
Martin v. Löwisc5574e82005-03-03 10:57:37 +00001772- Patch #1117454: Remove code to special-case cookies without values
1773 in LWPCookieJar.
1774
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00001775- Patch #1117339: Add cookielib special name tests.
1776
Martin v. Löwise869eb12005-03-03 09:46:07 +00001777- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
1778
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00001779- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
1780
Martin v. Löwisdf241532005-03-03 08:17:42 +00001781- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
1782
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00001783- Patch #1104111: Alter setup.py --help and --help-commands.
1784
Martin v. Löwis4afe1542005-03-01 08:09:28 +00001785- Patch #1121234: Properly cleanup _exit and tkerror commands.
1786
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001787- Patch #1049151: xdrlib now unpacks booleans as True or False.
1788
Raymond Hettingerbab41432005-02-05 01:31:19 +00001789- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1790
Guido van Rossumd0641422005-02-03 15:01:24 +00001791- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1792 disables recursive traversal through instance attributes, which can
1793 be exploited in various ways.
1794
Tim Peterse3547fd2005-12-16 23:13:57 +00001795- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001796 flags on the HTTP listening socket.
1797
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001798- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1799 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1800
Fred Drakefbdeaad2006-07-29 16:56:15 +00001801- Patches #893642, #1039083: add allow_none, encoding arguments to
1802 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001803
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001804- Bug #1110478: Revert os.environ.update to do putenv again.
1805
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001806- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1807
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001808- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1809
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001810- Enhancements to the csv module:
1811
1812 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001813 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001814 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001815 + Dialect parameter parsing has been re-implemented to improve error
1816 reporting.
1817 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1818 dictates.
1819 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001820 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001821 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001822 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1823 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001824 + reader now allows \r characters to be quoted (previously it only allowed
1825 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001826 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001827 + Dialect classes passed to the module are no longer instantiated by
1828 the module before being parsed (the former validation scheme required
1829 this, but the mechanism was unreliable).
1830 + The dialect registry now contains instances of the internal
1831 C-coded dialect type, rather than references to python objects.
1832 + the internal c-coded dialect type is now immutable.
1833 + register_dialect now accepts the same keyword dialect specifications
1834 as the reader and writer, allowing the user to register dialects
1835 without first creating a dialect class.
1836 + a configurable limit to the size of parsed fields has been added -
1837 previously, an unmatched quote character could result in the entire
1838 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001839 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001840 the parser field size limit (returning the former limit). The initial
1841 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001842 + A line_num attribute has been added to the reader object, which tracks
1843 the number of lines read from the source iterator. This is not
1844 the same as the number of records returned, as records can span
1845 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001846 + reader and writer objects were not being registered with the cyclic-GC.
1847 This has been fixed.
1848
Brett Cannone6539c42005-01-08 02:43:53 +00001849- _DummyThread objects in the threading module now delete self.__block that is
1850 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1851 lock primitives tend to be limited in number and thus should not be wasted on
1852 a _DummyThread object. Fixes bug #1089632.
1853
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001854- The imghdr module now detects Exif files.
1855
Raymond Hettinger6065d322004-12-20 23:51:53 +00001856- StringIO.truncate() now correctly adjusts the size attribute.
1857 (Bug #951915).
1858
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001859- locale.py now uses an updated locale alias table (built using
1860 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1861 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001862 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001863
Raymond Hettinger3557f422004-12-07 12:02:02 +00001864- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1865
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001866- the pickle module no longer accepts the deprecated None option in the
1867 args tuple returned by __reduce__().
1868
Brett Cannon84667c02004-12-07 03:25:18 +00001869- optparse now optionally imports gettext. This allows its use in setup.py.
1870
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001871- the pickle module no longer uses the deprecated bin parameter.
1872
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001873- the shelve module no longer uses the deprecated binary parameter.
1874
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001875- the pstats module no longer uses the deprecated ignore() method.
1876
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001877- the filecmp module no longer uses the deprecated use_statcache argument.
1878
Raymond Hettinger664347b2004-12-04 21:21:53 +00001879- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1880 extended or overridden by subclasses. Formerly, the subclassed method would
1881 be ignored by the rest of the module. (Bug #1078905).
1882
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001883- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001884 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001885
Walter Dörwald36733692004-12-22 12:50:50 +00001886- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1887 once when a size argument is given. This prevents a buffer overflow in the
1888 tokenizer with very long source lines.
1889
Barry Warsaw538561e2006-01-01 21:48:54 +00001890- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1891 immediately after creating the object, without any intervening
1892 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001893
Skip Montanaro05885812005-01-16 20:48:27 +00001894- The reconvert.quote function can now emit triple-quoted strings. The
1895 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001896
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001897- ``UserString.MutableString`` now supports negative indices in
1898 ``__setitem__`` and ``__delitem__``
1899
Greg Ward40407942005-03-05 02:53:17 +00001900- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1901 correctly.
1902
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001903- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1904 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1905 character even if the user has passed a size parameter to get a proper
1906 line ending. Remove the special handling of a "\r\n" that has been split
1907 between two lines.
1908
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001909- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1910 about illegal code points. The codec now supports PEP 293 style error
1911 handlers.
1912
Walter Dörwald78a78b02005-09-01 12:04:29 +00001913- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001914 from the input stream, so that the output is a byte string in the correct
1915 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001916
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001917- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1918 considering it exactly like a '*'.
1919
Walter Dörwald007f8df2005-10-09 19:42:27 +00001920- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1921 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001922
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001923- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1924
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001925- Patch #1413711: Certain patterns of differences were making difflib
1926 touch the recursion limit.
1927
Walter Dörwald58917a62006-03-31 15:26:22 +00001928- Bug #947906: An object oriented interface has been added to the calendar
1929 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001930 called as a script (e.g. via ``python -mcalendar``). Localized month and
1931 weekday names can be ouput (even if an exotic encoding is used) using
1932 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001934Build
1935-----
1936
Neal Norwitz602d3392006-03-31 08:21:40 +00001937- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1938 by using -mieee gcc option.
1939
Martin v. Löwis86d66262006-02-17 08:40:11 +00001940- Patch #1432345: Make python compile on DragonFly.
1941
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001942- Build support for Win64-AMD64 was added.
1943
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001944- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1945
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001946- Patch #881820: look for openpty and forkpty also in libbsd.
1947
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001948- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1949 The zlib module is now builtin on Windows.
1950
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001951- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1952
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001953- Bug #1189330: configure did not correctly determine the necessary
1954 value of LINKCC if python was built with GCC 4.0.
1955
Trent Mick8321b422005-07-26 02:29:21 +00001956- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1957 vulnerability in zlib 1.2.1 and 1.2.2.
1958
Brett Cannon08cd5982005-04-24 22:26:38 +00001959- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1960 flags that change binary compatibility. Changes were also made to
1961 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001962 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001963
Bob Ippolitoed233462005-03-29 13:47:59 +00001964- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1965 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1966 no longer exists). This configure patch makes things right.
1967
Martin v. Löwise2713be2005-03-08 15:03:08 +00001968- Bug #1158607: Build with --disable-unicode again.
1969
Brett Cannon46d96232005-02-16 00:07:19 +00001970- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1971 defined. Discovered as a result of not being able to build on OS X.
1972
Brett Cannon516592f2004-12-07 00:42:59 +00001973- setup.py now uses the directories specified in LDFLAGS using the -L option
1974 and in CPPFLAGS using the -I option for adding library and include
1975 directories, respectively, for compiling extension modules against. This has
1976 led to the core being compiled using the values in CPPFLAGS. It also removes
1977 the need for the special-casing of both DarwinPorts and Fink for darwin since
1978 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1979 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1980 Fink, ``-I/opt/local/include`` for DarwinPorts).
1981
Brett Cannon43802422005-02-10 20:48:03 +00001982- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1983 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1984 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1985 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001987C API
1988-----
1989
Tim Petersc9d78aa2006-03-26 23:27:58 +00001990- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1991 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1992 is obtained via the ``PyObject_`` family, it must be released via the
1993 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1994 always been officially true, but when Python's small-object allocator was
1995 introduced, an attempt was made to cater to a few extension modules
1996 discovered at the time that obtained memory via ``PyObject_New`` but
1997 released it via ``PyMem_DEL``. It's years later, and if such code still
1998 exists it will fail now (probably with segfaults, but calling wrong
1999 low-level memory management functions can yield many symptoms).
2000
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002001- Added a C API for set and frozenset objects.
2002
