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
Georg Brandl0a7d1bb2006-08-11 07:26:10 +000067- logging's atexit hook now runs even if the rest of the module has
68 already been cleaned up.
69
Guido van Rossum133f4e42006-08-10 17:42:50 +000070- Bug #1112549, DoS attack on cgi.FieldStorage.
71
Neal Norwitzff4b63b2006-08-04 04:50:21 +000072- Bug #1531405, format_exception no longer raises an exception if
73 str(exception) raised an exception.
74
Neil Schemenauer06ded092006-08-04 16:20:30 +000075- Fix a bug in the ``compiler`` package that caused invalid code to be
76 generated for nested functions.
77
Neal Norwitzff4b63b2006-08-04 04:50:21 +000078
79Extension Modules
80-----------------
81
Thomas Heller86720042006-08-14 11:17:48 +000082- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
83 uses the _as_parameter_ attribute when objects are passed to foreign
84 function calls. The ctypes version number was changed to 1.0.1.
85
Bob Ippolitoe6c9f982006-08-04 23:59:21 +000086- Bug #1530559, struct.pack raises TypeError where it used to convert.
87 Passing float arguments to struct.pack when integers are expected
88 now triggers a DeprecationWarning.
89
Neal Norwitzff4b63b2006-08-04 04:50:21 +000090
91Tests
92-----
93
Neal Norwitz003c9e22006-08-11 06:09:41 +000094- test_mailbox should now work on cygwin versions 2006-08-10 and later.
95
Georg Brandl9908d162006-08-06 07:06:33 +000096- Bug #1535182: really test the xreadlines() method of bz2 objects.
97
Andrew MacIntyre16ee33a2006-08-06 12:37:03 +000098- test_threading now skips testing alternate thread stack sizes on
99 platforms that don't support changing thread stack size.
100
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000101
Georg Brandl212b5872006-08-05 06:10:54 +0000102Documentation

109-----
110
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000111- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.
112
Thomas Heller17984892006-08-04 18:57:34 +0000113- Bug #1530448, ctypes buld failure on Solaris 10 was fixed.
114
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000115
Tim Peters4643c2f2006-08-10 22:45:34 +0000116C API

Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000119- New API for Unicode rich comparisons: PyUnicode_RichCompare()
120
Tim Peters4643c2f2006-08-10 22:45:34 +0000121- Bug #1069160. Internal correctness changes were made to
122 ``PyThreadState_SetAsyncExc()``. A test case was added, and
123 the documentation was changed to state that the return value
124 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000131What's New in Python 2.5 beta 3?
132================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000133
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000134*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000135
136Core and builtins
137-----------------
138
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000139- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t, it previously
140 returned a long (see PEP 353).
141
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000142- Bug #1515471: string.replace() accepts character buffers again.
143
Neal Norwitz07aadb12006-07-30 06:55:48 +0000144- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
145 This provides the proper warning for struct.pack().
146 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
147
Neal Norwitz0d62a062006-07-30 06:53:31 +0000148- Patch #1531113: Fix augmented assignment with yield expressions.
149 Also fix a SystemError when trying to assign to yield expressions.
150
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000151- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
152 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
153 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
154 excessive filesystem operations during imports.
155
Tim Petersbc24eee2006-07-27 01:14:53 +0000156- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
157 operations on signed longs that are formally undefined by C.
158 Unfortunately, at least one compiler now cares about that, so complicated
159 the code to make that compiler happy again.
160
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000161- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
162
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000163- Patch #1232023: Stop including current directory in search
164 path on Windows.
165
Neal Norwitze1fdb322006-07-21 05:32:28 +0000166- Fix some potential crashes found with failmalloc.
167
Neal Norwitze7563102006-07-17 01:00:16 +0000168- Fix warnings reported by Klocwork's static analysis tool.
169
Neal Norwitz84be93b2006-07-16 01:50:38 +0000170- Bug #1512814, Fix incorrect lineno's when code within a function
171 had more than 255 blank lines.
172
Georg Brandl9dceedb2006-07-12 15:31:17 +0000173- Patch #1521179: Python now accepts the standard options ``--help`` and
174 ``--version`` as well as ``/?`` on Windows.
175
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000176- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000177 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000178 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000179
Tim Peters112aad32006-07-19 00:03:19 +0000180- Bug #1524317: Compiling Python ``--without-threads`` failed.
181 The Python core compiles again then, and, in a build without threads, the
182 new ``sys._current_frames()`` returns a dictionary with one entry,
183 mapping the faux "thread id" 0 to the current frame.
184
Ronald Oussoren3075e162006-07-25 20:28:55 +0000185- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000186
Ronald Oussoren3075e162006-07-25 20:28:55 +0000187
Neal Norwitza1f10902006-07-12 07:28:29 +0000188Library
189-------
190
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000191- Correction of patch #1455898: In the mbcs decoder, set final=False
192 for stream decoder, but final=True for the decode function.
193
Georg Brandl07fec3a2006-08-01 18:49:24 +0000194- os.urandom no longer masks unrelated exceptions like SystemExit or
195 KeyboardInterrupt.
196
Tim Peters4643c2f2006-08-10 22:45:34 +0000197- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000198 shutil.copytree on Windows
199
Georg Brandle34ac7c2006-07-30 11:07:23 +0000200- Bug #1002398: The documentation for os.path.sameopenfile now correctly
201 refers to file descriptors, not file objects.
202
Fred Drakefbdeaad2006-07-29 16:56:15 +0000203- Rename of the xml package to xmlcore, and the import hackery done to
204 make it appear at both names, has been removed. Bug #1511497,
205 #1513611, and probably others.
206
Georg Brandledd9b0d2006-07-29 09:33:26 +0000207- Bug #1441397: The compiler module now recognizes module and function
208 docstrings correctly as it did in Python 2.4.
209
Tim Peters6f681472006-07-27 23:44:37 +0000210- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
211 lost that tests are sorted by name before being run. This rarely
212 matters for well-written tests, but can create baffling symptoms if
213 side effects from one test to the next affect outcomes. ``DocTestFinder``
214 has been changed to sort the list of tests it returns.
215
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000216- The distutils version has been changed to 2.5.0, and are now kept
217 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000218
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000219- Bug #978833: Really close underlying socket in _socketobject.close.
220
Georg Brandl0619a322006-07-26 07:40:17 +0000221- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
222 with title().
223
Georg Brandlcf0c1722006-07-26 07:23:32 +0000224- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
225 to recursive calls and call it with the failing package name.
226
Martin v. Löwis0b483032006-07-25 09:53:12 +0000227- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
228
Georg Brandlc13c34c2006-07-24 14:09:56 +0000229- Patch #1515343: Fix printing of deprecated string exceptions with a
230 value in the traceback module.
231
Greg Ward48fae7a2006-07-23 16:05:51 +0000232- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
233
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000234- Patch #1524429: Use repr() instead of backticks in Tkinter again.
235
Brett Cannoncaebe222006-07-18 04:41:36 +0000236- Bug #1520914: Change time.strftime() to accept a zero for any position in its
237 argument tuple. For arguments where zero is illegal, the value is forced to
238 the minimum value that is correct. This is to support an undocumented but
239 common way people used to fill in inconsequential information in the time
240 tuple pre-2.4.
241
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000242- Patch #1220874: Update the binhex module for Mach-O.
243
Barry Warsawb110bad2006-07-21 14:51:07 +0000244- The email package has improved RFC 2231 support, specifically for
245 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
246 (name*0=<blah>) parameter continuations. This may change the types of
247 values returned from email.message.Message.get_param() and friends.
248 Specifically in some cases where non-encoded continuations were used,
249 get_param() used to return a 3-tuple of (None, None, string) whereas now it
250 will just return the string (since non-encoded continuations don't have
251 charset and language parts).
252
253 Also, whereas % values were decoded in all parameter continuations, they are
254 now only decoded in encoded parameter parts.
255
Ronald Oussoren3075e162006-07-25 20:28:55 +0000256- Bug #1517990: IDLE keybindings on MacOS X now work correctly
257
258- Bug #1517996: IDLE now longer shows the default Tk menu when a
259 path browser, class browser or debugger is the frontmost window on MacOS X
260
Barry Warsaw00decd72006-07-27 23:43:15 +0000261- Patch #1520294: Support for getset and member descriptors in types.py,
262 inspect.py, and pydoc.py. Specifically, this allows for querying the type
263 of an object against these built-in types and more importantly, for getting
264 their docstrings printed in the interactive interpreter's help() function.
265
Ronald Oussoren3075e162006-07-25 20:28:55 +0000266
Neal Norwitza1f10902006-07-12 07:28:29 +0000267Extension Modules
268-----------------
269
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000270- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
271 a socket operation on a socket with a timeout, the exception will be
272 caught correctly. Previously, the exception was not caught.
273
Thomas Heller1393d6a2006-07-28 21:43:20 +0000274- Patch #1529514: The _ctypes extension is now compiled on more
275 openbsd target platforms.
276
Tim Peters9cab5932006-07-28 00:30:00 +0000277- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
278 a memory leak, affecting pickles and deep copies.
279
Tim Petersbc24eee2006-07-27 01:14:53 +0000280- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000281 Paul Eggert.
282
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000283- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
284
Thomas Hellerce049a02006-07-14 17:51:14 +0000285- Patch #1521817: Index range checking on ctypes arrays containing
286 exactly one element enabled again. This allows iterating over these
287 arrays, without the need to check the array size before.
288
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000289- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000290 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000291 /dev/null in certain cases; this is now fixed.
292
Thomas Heller47d7a062006-07-12 08:43:47 +0000293- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
294 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000295
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000296- Because of a misspelled preprocessor symbol, ctypes was always
297 compiled without thread support; this is now fixed.
298
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000299- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
300 methods now allow their database parameter to be None as the
301 sleepycat API allows.
302
Matt Flemingec926502006-07-28 11:27:27 +0000303- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
304 bluetooth API compared with Linux and FreeBSD.
305
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000306Tests
307-----
308
309- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
310 how long the test file should take to play. Now accepts taking 2.93 secs
311 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
312
Georg Brandl4793aa32006-07-28 18:31:39 +0000313- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
314 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when

325- PythonLauncher now works correctly when the path to the script contains
326 characters that are treated specially by the shell (such as quotes).
327
328- Bug #1527397: PythonLauncher now launches scripts with the working directory
329 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000330 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000331 expect.

339Core and builtins
340-----------------
341
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000342- Bug #1441486: The literal representation of -(sys.maxint - 1)
343 again evaluates to a int object, not a long.
344
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000345- Bug #1501934: The scope of global variables that are locally assigned
346 using augmented assignment is now correctly determined.
347
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000348- Bug #927248: Recursive method-wrapper objects can now safely
349 be released.
350
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000351- Bug #1417699: Reject locale-specific decimal point in float()
352 and atof().
353
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000354- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
355 omit a default "error" argument for NULL pointer. This allows
356 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000357
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000358- Bug #1519018: 'as' is now validated properly in import statements.
359
Neal Norwitz28746ab2006-07-09 22:14:42 +0000360- On 64 bit systems, int literals that use less than 64 bits are
361 now ints rather than longs.
362
Neal Norwitzed657552006-07-10 00:04:44 +0000363- Bug #1512814, Fix incorrect lineno's when code at module scope
364 started after line 256.
365
Tim Peters32a83612006-07-10 21:08:24 +0000366- New function ``sys._current_frames()`` returns a dict mapping thread
367 id to topmost thread stack frame. This is for expert use, and is
368 especially useful for debugging application deadlocks. The functionality
369 was previously available in Fazal Majid's ``threadframe`` extension
370 module, but it wasn't possible to do this in a wholly threadsafe way from
371 an extension.

380
Tim Peters32a83612006-07-10 21:08:24 +0000381- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000382 environment variable to be set in order to the SDK environment
383 for finding the compiler, include files, etc.

388
Thomas Woutersadd19112006-07-05 11:03:49 +0000389- string.Template() now correctly handles tuple-values. Previously,
390 multi-value tuples would raise an exception and single-value tuples would
391 be treated as the value they contain, instead.
392
Martin v. Löwisede77f52006-07-03 13:01:35 +0000393- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000402- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000403 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000404

406 is created.
407
Martin v. Löwis7596e832006-07-01 15:33:37 +0000408- Bug #1513223: .close() of a _socketobj now releases the underlying
409 socket again, which then gets closed as it becomes unreferenced.
410
Fred Drake10497c82006-06-29 02:57:48 +0000411- Bug #1504333: Make sgmllib support angle brackets in quoted
412 attribute values.
413
414- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
415 sgmllib ('[' and ']' were not accepted).
416
Georg Brandl1be63af2006-06-28 20:23:25 +0000417- Fix a bug in the turtle module's end_fill function.
418
Brett Cannon53ab5b72006-06-22 16:49:14 +0000419- Bug #1510580: The 'warnings' module improperly required that a Warning
420 category be either a types.ClassType and a subclass of Warning. The proper
421 check is just that it is a subclass with Warning as the documentation states.
422
Georg Brandlad29e632006-06-21 17:45:17 +0000423- The compiler module now correctly compiles the new try-except-finally
424 statement (bug #1509132).
425
Neal Norwitz60373cd2006-06-22 06:30:50 +0000426- The wsgiref package is now installed properly on Unix.
427
Vinay Sajip28e57612006-07-01 10:45:20 +0000428- A bug was fixed in logging.config.fileConfig() which caused a crash on
429 shutdown when fileConfig() was called multiple times.
430
Gerhard Häring762fbd32006-07-02 17:48:30 +0000431- The sqlite3 module did cut off data from the SQLite database at the first
432 null character before sending it to a custom converter. This has been fixed
433 now.
434
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000435Extension Modules
436-----------------
437
Tim Peters112aad32006-07-19 00:03:19 +0000438- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
439 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
440 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000441
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000442- Assigning None to pointer type fields in ctypes structures possible
443 overwrote the wrong fields, this is fixed now.
444
445- Fixed a segfault in _ctypes when ctypes.wintypes were imported
446 on non-Windows platforms.
447
448- Bug #1518190: The ctypes.c_void_p constructor now accepts any
449 integer or long, without range checking.
450
451- Patch #1517790: It is now possible to use custom objects in the ctypes
452 foreign function argtypes sequence as long as they provide a from_param
453 method, no longer is it required that the object is a ctypes type.
454
455- The '_ctypes' extension module now works when Python is configured
456 with the --without-threads option.
457
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000458- Bug #1513646: os.access on Windows now correctly determines write
459 access, again.
460
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000461- Bug #1512695: cPickle.loads could crash if it was interrupted with
462 a KeyboardInterrupt.
463
Neal Norwitza12aa882006-07-06 06:45:08 +0000464- Bug #1296433: parsing XML with a non-default encoding and
465 a CharacterDataHandler could crash the interpreter in pyexpat.

470-----
471
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000472- Automate Windows build process for the Win64 SSL module.
473
Tim Peters32a83612006-07-10 21:08:24 +0000474- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000475 Previously, the slight difference could cause compilation errors of the
476 'zlib' module on systems with more than one version of zlib.
477
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000478- The MSI compileall step was fixed to also support a TARGETDIR
479 with spaces in it.
480
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000481- Bug #1517388: sqlite3.dll is now installed on Windows independent
482 of Tcl/Tk.
483
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000484- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000485 trying to be installed even though it's empty.

509Core and builtins
510-----------------
511
Georg Brandla56b9152006-06-19 06:35:54 +0000512- Patch #1507676: Error messages returned by invalid abstract object operations
513 (such as iterating over an integer) have been improved and now include the
514 type of the offending object to help with debugging.
515
Brett Cannonea3912b2006-06-13 21:46:41 +0000516- Bug #992017: A classic class that defined a __coerce__() method that returned
517 its arguments swapped would infinitely recurse and segfault the interpreter.
518
Neal Norwitz909eb122006-06-12 02:13:21 +0000519- Fix the socket tests so they can be run concurrently.
520
Neal Norwitzb9845e72006-06-12 02:11:18 +0000521- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000522 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000523
Brett Cannon22565aa2006-06-09 22:31:23 +0000524- Bug #532646: object.__call__() will continue looking for the __call__
525 attribute on objects until one without one is found. This leads to recursion
526 when you take a class and set its __call__ attribute to an instance of the
527 class. Originally fixed for classic classes, but this fix is for new-style.
528 Removes the infinite_rec_3 crasher.
529
Georg Brandl24250812006-06-09 18:45:48 +0000530- The string and unicode methods startswith() and endswith() now accept
531 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
532
Brett Cannonde3b0522006-06-08 17:00:45 +0000533- Buffer objects, at the C level, never used the char buffer
534 implementation even when the char buffer for the wrapped object was
535 explicitly requested (originally returned the read or write buffer).
536 Now a TypeError is raised if the char buffer is not present but is
537 requested.
538
Georg Brandlddbaa662006-06-04 21:56:52 +0000539- Patch #1346214: Statements like "if 0: suite" are now again optimized
540 away like they were in Python 2.4.
541
Georg Brandlb7c8f542006-05-27 12:30:25 +0000542- Builtin exceptions are now full-blown new-style classes instead of
543 instances pretending to be classes, which speeds up exception handling
544 by about 80% in comparison to 2.5a2.
545
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000546- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
547 Unicode 4.1.
548
Georg Brandlf4ef1162006-05-26 18:03:31 +0000549- Patch #921466: sys.path_importer_cache is now used to cache valid and
550 invalid file paths for the built-in import machinery which leads to
551 fewer open calls on startup.
552
Tim Peters696cf432006-05-24 21:10:40 +0000553- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
554 of-2 bases. The largest speedup is for inputs with about 1000 decimal
555 digits. Conversion from non-power-of-2 bases remains quadratic-time in
556 the number of input digits (it was and remains linear-time for bases
557 2, 4, 8, 16 and 32).
558
Tim Petersb713ec22006-05-23 18:45:30 +0000559- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
560 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
561 an integer close to ``sys.maxint``. This was repaired by patch
562 #1335972, which also gives a nice speedup.
563
Richard Jonescebbefc2006-05-23 18:28:17 +0000564- Patch #1337051: reduced size of frame objects.
565
566- PyErr_NewException now accepts a tuple of base classes as its
567 "base" parameter.
568
Richard Jones7c88dcc2006-05-23 10:37:38 +0000569- Patch #876206: function call speedup by retaining allocated frame
570 objects.
571
Georg Brandl7b90e162006-05-18 07:01:27 +0000572- Bug #1462152: file() now checks more thoroughly for invalid mode
573 strings and removes a possible "U" before passing the mode to the
574 C library function.
575
Neal Norwitz1004a532006-05-15 07:17:23 +0000576- Patch #1488312, Fix memory alignment problem on SPARC in unicode
577
Neal Norwitz373f0a72006-05-15 07:04:36 +0000578- Bug #1487966: Fix SystemError with conditional expression in assignment
579
Martin v. Löwis879768d2006-05-11 13:28:43 +0000580- WindowsError now has two error code attributes: errno, which carries
581 the error values from errno.h, and winerror, which carries the error
582 values from winerror.h. Previous versions put the winerror.h values
583 (from GetLastError()) into the errno attribute.
584
Martin v. Löwis77736712006-05-04 05:51:03 +0000585- Patch #1475845: Raise IndentationError for unexpected indent.
586
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000587- Patch #1479181: split open() and file() from being aliases for each other.
588
Tim Peters44bd9862006-06-01 13:49:23 +0000589- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
590 methods were always silently ignored by dictionaries when comparing keys.
591 They are now passed through (except when using the C API function
592 ``PyDict_GetItem()``, whose semantics did not change).
593
594- Bug #1456209: In some obscure cases it was possible for a class with a
595 custom ``__eq__()`` method to confuse dict internals when class instances
596 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
597 No, you don't have any code that did this ;-)

604- Patch #1462338: Upgrade pyexpat to expat 2.0.0
605
Brett Cannon6ee7d012006-06-08 16:23:04 +0000606- Change binascii.hexlify to accept a read-only buffer instead of only a char
607 buffer and actually follow its documentation.
608

610
Nick Coghlanc649ec52006-05-29 12:43:05 +0000611- Patch #1478788 (modified version): The functional extension module has
612 been renamed to _functools and a functools Python wrapper module added.
613 This provides a home for additional function related utilities that are
614 not specifically about functional programming. See PEP 309.
615

625
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000626- On Win32, os.listdir now supports arbitrarily-long Unicode path names
627 (up to the system limit of 32K characters).
628
629- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
630 As a result, these functions now raise WindowsError instead of OSError.
631
Tim Peters7a822da2006-05-25 21:50:17 +0000632- ``time.clock()`` on Win64 should use the high-performance Windows
633 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
634 Windows platforms).
635
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000636- Calling Tk_Init twice is refused if the first call failed as that
637 may deadlock.
638
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000639- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
640 accept it without potentially using an uninitialized pointer.
641
642- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
643 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
644 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000645
Gregory P. Smith372b5832006-06-05 18:48:21 +0000646- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000647 [pybsddb project SF patch number 1466734]
648
Gregory P. Smith372b5832006-06-05 18:48:21 +0000649- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
650 parameter is supplied. [SF pybsddb bug #1477863]
651
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000652- bsddb: the __len__ method of a DB object has been fixed to return correct
653 results. It could previously incorrectly return 0 in some cases.
654 Fixes SF bug 1493322 (pybsddb bug 1184012).
655
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000656- bsddb: the bsddb.dbtables Modify method now raises the proper error and
657 aborts the db transaction safely when a modifier callback fails.
658 Fixes SF python patch/bug #1408584.
659
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000660- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000661 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000662 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
663 database calls that would previously deadlock. [SF python bug #775414]
664
Vinay Sajip28e57612006-07-01 10:45:20 +0000665- Patch #1446489: add support for the ZIP64 extensions to zipfile.

687 mime.types file for determining MIME types.
688
Georg Brandl2605ca82006-06-14 06:08:31 +0000689- Bug #1339007: Shelf objects now don't raise an exception in their
690 __del__ method when initialization failed.
691
Martin v. Löwisd8251432006-06-14 05:21:04 +0000692- Patch #1455898: The MBCS codec now supports the incremental mode for
693 double-byte encodings.
694
Tim Peters43898b42006-06-14 04:09:25 +0000695- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
696 guarantee that adjacent triples in the return list always describe
697 non-adjacent blocks. Previously, a pair of matching blocks could end
698 up being described by multiple adjacent triples that formed a partition
699 of the matching pair.
700
Greg Ward0e0c9f42006-06-11 16:24:11 +0000701- Bug #1498146: fix optparse to handle Unicode strings in option help,
702 description, and epilog.
703
Greg Wardd1c797e2006-06-11 14:42:41 +0000704- Bug #1366250: minor optparse documentation error.

707 clarify docs.
708
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000709- The wsgiref package has been added to the standard library.
710
Nick Coghlan676725d2006-06-08 13:54:49 +0000711- The functions update_wrapper() and wraps() have been added to the functools
712 module. These make it easier to copy relevant metadata from the original
713 function when writing wrapper functions.
714
Tim Petersd6a9eef2006-06-05 01:48:21 +0000715- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
716 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000717
Martin v. Löwis3f767792006-06-04 19:36:28 +0000718- Patch #1359618: Speed up charmap encoder by using a trie structure
719 for lookup.
720
Tim Petersd609b1a2006-06-02 23:22:51 +0000721- The functions in the ``pprint`` module now sort dictionaries by key
722 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
723 if and only if its display required more than one line, although that
724 wasn't documented. The new behavior increases predictability; e.g.,
725 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
726
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000727- Patch #1497027: try HTTP digest auth before basic auth in urllib2

734
Bob Ippolito7298f272006-05-23 18:43:47 +0000735- Patch #1281707: speed up gzip.readline.
736
Georg Brandlb89316f2006-05-17 15:51:16 +0000737- Patch #1180296: Two new functions were added to the locale module:
738 format_string() to get the effect of "format % items" but locale-aware,
739 and currency() to format a monetary number with currency sign.
740
Georg Brandle3a25832006-05-17 14:56:04 +0000741- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
742 and several features added, such as speed and geometry control.
743

745 tarfiles.
746
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000747- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
748 stdout arguments, making it possible to redirect input and output
749 for remote debugging.
750
751- Patch #1484695: Update the tarfile module to version 0.8. This fixes
752 a couple of issues, notably handling of long file names using the
753 GNU LONGNAME extension.
754
755- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
756 new flag when ``name`` is already the name of an option flag.
757
758- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
759 package.
760
761- Patch #1472854: make the rlcompleter.Completer class usable on non-
762 UNIX platforms.
763

798=================================
799
800*Release date: 27-APR-2006*
801
802Core and builtins
803-----------------
804
Thomas Heller1b046642006-04-18 18:51:06 +0000805- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
806 by converting these apis from macros into exported functions again:
807
808 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
809 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
810 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
811 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
812 PyRun_String Py_CompileString
813
Martin v. Löwis45294a92006-04-18 06:24:08 +0000814- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
815
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000816- All uses of PyStructSequence_InitType have been changed to initialize
817 the type objects only once, even if the interpreter is initialized
818 multiple times.
819
Neal Norwitz61546162006-04-14 05:20:28 +0000820- Bug #1454485, array.array('u') could crash the interpreter. This was
821 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
822 to unicode when it didn't make sense. 'u#' now requires a unicode string.
823
824- Py_UNICODE is unsigned. It was always documented as unsigned, but
825 due to a bug had a signed value in previous versions.
826
Tim Peters3a5e8b12006-04-11 01:44:07 +0000827- Patch #837242: ``id()`` of any Python object always gives a positive
828 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
829 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000830 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000831 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000832
Tim Peters3a5e8b12006-04-11 01:44:07 +0000833 def __hash__(self):
834 return id(self) # WRONG
835
836 because a hash result must be a (short) Python int but it was always
837 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000838 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000839 was always usable as a hash value before this patch. That's no longer
840 necessarily so.
841
842- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000843 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000844 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000845 #1454844)
846
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000847- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
848 involving generators that have paused outside of any ``try`` or ``with``
849 blocks. (In 2.5a1, a paused generator that was part of a reference
850 cycle could not be garbage collected, regardless of whether it was
851 paused in a ``try`` or ``with`` block.)

870- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
871 as older versions cause excessive test failures.

878
Peter Astrand7d1d4362006-07-14 14:04:45 +0000879- Bug #1223937: subprocess.CalledProcessError reports the exit status
880 of the process using the returncode attribute, instead of
881 abusing errno.
882
Tim Peters711bf302006-04-25 03:31:36 +0000883- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
884 a doctest to be skipped (the code is not run, and the expected output
885 or exception is ignored).
886
Nick Coghlanda2268f2006-04-24 04:37:15 +0000887- Fixed contextlib.nested to cope with exceptions being raised and
888 caught inside exit handlers.
889
Greg Wardab05edc2006-04-23 03:47:58 +0000890- Updated optparse module to Optik 1.5.1 (allow numeric constants in
891 hex, octal, or binary; add ``append_const`` action; keep going if
892 gettext cannot be imported; added ``OptionParser.destroy()`` method;
893 added ``epilog`` for better help generation).
894
Tim Peters21fbd572006-04-21 21:18:10 +0000895- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
896 called from a thread spawned as a side effect of importing a module.
897
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000898- The pydoc module now supports documenting packages contained in
899 .zip or .egg files.
900
901- The pkgutil module now has several new utility functions, such
902 as ``walk_packages()`` to support working with packages that are either
903 in the filesystem or zip files.
904
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000905- The mailbox module can now modify and delete messages from
906 mailboxes, in addition to simply reading them. Thanks to Gregory
907 K. Johnson for writing the code, and to the 2005 Google Summer of
908 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000909
Tim Petersc7605f22006-04-17 21:12:33 +0000910- The ``__del__`` method of class ``local`` in module ``_threading_local``
911 returned before accomplishing any of its intended cleanup.
912

Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000945
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000946- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
947 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000948 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000949 CXX from --with-cxx-main, see description in README.
950
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000951- Patch #1429775: Link extension modules with the shared libpython.
952
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000953- Fixed a libffi build problem on MIPS systems.
954
Tim Peters8931ff12006-05-13 23:28:20 +0000955- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
956 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
957 and "%zu" for unsigned integers of type ``size_t``.

960-----
961
Nick Coghlanda2268f2006-04-24 04:37:15 +0000962- test_contextlib now checks contextlib.nested can cope with exceptions
963 being raised and caught inside exit handlers.
964
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000965- test_cmd_line now checks operation of the -m and -c command switches
966
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000967- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
968 it separately and by hand. It also wasn't cleaning up its changes to
969 the current Decimal context.
970
Thomas Woutersabd08882006-04-26 15:53:30 +0000971- regrtest.py now has a -M option to run tests that test the new limits of
972 containers, on 64-bit architectures. Running these tests is only sensible
973 on 64-bit machines with more than two gigabytes of memory. The argument
974 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000982Documentation
983-------------
984
Tim Petersb06d28c2006-05-12 01:57:59 +0000985- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
986
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000987- PEP 343: Added Context Types section to the library reference
988 and attempted to bring other PEP 343 related documentation into
989 line with the implementation and/or python-dev discussions.
990
Tim Peters8dc73d22006-04-24 02:03:16 +0000991- Bug #1337990: clarified that ``doctest`` does not support examples
992 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000995What's New in Python 2.5 alpha 1?
996=================================
997
Anthony Baxterebed3f62006-04-03 15:03:44 +0000998*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000999
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001000Core and builtins
1001-----------------
1002
Nick Coghlan43832302006-04-23 17:04:07 +00001003- PEP 338: -m command line switch now delegates to runpy.run_module
1004 allowing it to support modules in packages and zipfiles
1005
Martin v. Löwisc661b882006-04-20 04:54:23 +00001006- On Windows, .DLL is not an accepted file name extension for
1007 extension modules anymore; extensions are only found if they
1008 end in .PYD.
1009
Martin v. Löwisea62d252006-04-03 10:56:49 +00001010- Bug #1421664: sys.stderr.encoding is now set to the same value as
1011 sys.stdout.encoding.
1012
Neal Norwitz92e212f2006-04-03 04:48:37 +00001013- __import__ accepts keyword arguments.
1014
Georg Brandlccadf842006-03-31 18:54:53 +00001015- Patch #1460496: round() now accepts keyword arguments.
1016
Anthony Baxter262c00a2006-03-30 10:53:17 +00001017- Fixed bug #1459029 - unicode reprs were double-escaped.
1018
Hye-Shik Changd478f342006-03-23 12:32:36 +00001019- Patch #1396919: The system scope threads are reenabled on FreeBSD
1020 5.4 and later versions.
1021
Neal Norwitze98ccf62006-03-23 05:39:47 +00001022- Bug #1115379: Compiling a Unicode string with an encoding declaration
1023 now gives a SyntaxError.
1024
Georg Brandlabd1ff82006-03-18 07:59:59 +00001025- Previously, Python code had no easy way to access the contents of a
1026 cell object. Now, a ``cell_contents`` attribute has been added
1027 (closes patch #1170323).
1028
Tim Peterscf79aac2006-03-16 01:14:46 +00001029- Patch #1123430: Python's small-object allocator now returns an arena to
1030 the system ``free()`` when all memory within an arena becomes unused
1031 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1032 freed. Some applications will see a drop in virtual memory size now,
1033 especially long-running applications that, from time to time, temporarily
1034 use a large number of small objects. Note that when Python returns an
1035 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001036 platform C library will in turn return that memory to the operating system.
1037 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001038 appears to be effective at least on Microsoft C and gcc-based systems.
1039 Thanks to Evan Jones for hard work and patience.
1040
Georg Brandl533ff6f2006-03-08 18:09:27 +00001041- Patch #1434038: property() now uses the getter's docstring if there is
1042 no "doc" argument given. This makes it possible to legitimately use
1043 property() as a decorator to produce a read-only property.
1044
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001045- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1046 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1047 of requiring an int or long in slicing and a few other contexts, enabling
1048 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1049
Neal Norwitz995acdf2006-03-07 05:01:00 +00001050- Fixed various bugs reported by Coverity's Prevent tool.
1051
Brett Cannonbf364092006-03-01 04:25:17 +00001052- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1053 new exception base class, BaseException, which has a new message attribute.
1054 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1055 Raising a string exception now raises a DeprecationWarning.
1056
Thomas Woutersfb609f42006-02-28 16:37:25 +00001057- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1058 explicitly relative, using 'from .module import name' to mean 'from the same
1059 package as this module is in. Imports without dots still default to the
1060 old relative-then-absolute, unless 'from __future__ import
1061 absolute_import' is used.
1062
Brett Cannona7446e32006-02-27 23:39:10 +00001063- Properly check if 'warnings' raises an exception (usually when a filter set
1064 to "error" is triggered) when raising a warning for raising string
1065 exceptions.
1066
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001067- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001068 The name was removed from Include/code.h.
1069
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001070- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001071
Guido van Rossum1968ad32006-02-25 22:38:04 +00001072- Patch 1433928:
1073 - The copy module now "copies" function objects (as atomic objects).
1074 - dict.__getitem__ now looks for a __missing__ hook before raising
1075 KeyError.
1076
Tim Peters84ef21c2006-02-28 20:39:06 +00001077- PEP 343: with statement implemented. Needs ``from __future__ import
1078 with_statement``. Use of 'with' as a variable will generate a warning.
1079 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001080 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001081 The following objects have __context__ methods:
1082 - The built-in file type.
1083 - The thread.LockType type.
1084 - The following types defined by the threading module:
1085 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1086 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001087
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001088- Fix the encodings package codec search function to only search
1089 inside its own package. Fixes problem reported in patch #1433198.
1090
1091 Note: Codec packages should implement and register their own
1092 codec search function. PEP 100 has the details.
1093
Tim Peters9ea89d22006-06-04 03:26:02 +00001094- PEP 353: Using ``Py_ssize_t`` as the index type.
1095
1096- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1097 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1098 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1099 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1100 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001101
Neal Norwitzfc76d632006-01-10 06:03:13 +00001102- Patch #1400181, fix unicode string formatting to not use the locale.
1103 This is how string objects work. u'%f' could use , instead of .
1104 for the decimal point. Now both strings and unicode always use periods.
1105
Neal Norwitz671b9e32006-01-09 07:07:12 +00001106- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1107 configure would break checking curses.h.
1108
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001109- Bug #959576: The pwd module is now builtin. This allows Python to be
1110 built on UNIX platforms without $HOME set.
1111
Neal Norwitzc10978f2005-12-19 06:07:16 +00001112- Bug #1072182, fix some potential problems if characters are signed.
1113
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001114- Bug #889500, fix line number on SyntaxWarning for global declarations.
1115
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001116- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1117
Neal Norwitze7214a12005-12-18 05:03:17 +00001118- Support for converting hex strings to floats no longer works.
1119 This was not portable. float('0x3') now raises a ValueError.
1120
Barry Warsaw2a38a862005-12-18 01:27:35 +00001121- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001122 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001123 is now displayed in interactive prompt banner.
1124
Georg Brandlfa166682005-12-17 21:45:17 +00001125- Implementation of PEP 341 - Unification of try/except and try/finally.
1126 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001127 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001128
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001129- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1130 now encodes backslash correctly.
1131
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001132- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1133
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001134- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001135 and long longs.
1136
Neal Norwitz67715f02005-11-09 06:59:35 +00001137- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001138 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001139 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001140
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001141- Replaced most Unicode charmap codecs with new ones using the
1142 new Unicode translate string feature in the builtin charmap
1143 codec; the codecs were created from the mapping tables available
1144 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1145 encodings now include a mapping for the Apple logo)
1146
Tim Peterse3547fd2005-12-16 23:13:57 +00001147- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001148
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001149- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001150
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001151- A new AST parser implementation was completed. The abstract
1152 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001153 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001154
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001155- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001156 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1157
Neal Norwitz708e51a2005-10-03 04:48:15 +00001158- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1159
Neal Norwitz11bd1192005-10-03 00:54:56 +00001160- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1161 Provide a warning when a directory is passed on the command line.
1162
Neal Norwitz40d37812005-10-02 01:48:49 +00001163- Fix segfault with invalid coding.
1164
1165- SF bug #772896: unknown encoding results in MemoryError.
1166
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001167- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001168 supported a __len__() method which evaluated to False when the iterator
1169 was empty.
1170
Guido van Rossum630db602005-09-20 18:49:54 +00001171- On 64-bit platforms, when __len__() returns a value that cannot be
1172 represented as a C int, raise OverflowError.
1173
Skip Montanarof8948ca2005-09-19 03:54:46 +00001174- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001175 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001176
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001177- SF bug #893549: parsing keyword arguments was broken with a few format
1178 codes.
1179
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001180- Changes donated by Elemental Security to make it work on AIX 5.3
1181 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1182 bug #105470: test_pwd fails on 64bit system (Opteron).
1183
Guido van Rossum539c6622005-09-14 17:49:54 +00001184- Changes donated by Elemental Security to make it work on HP-UX 11 on
1185 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1186
Georg Brandl4550b8d2005-08-26 06:43:52 +00001187- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001188 (fixes bug #1119418).
1189
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001190- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1191
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001192- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1193 exceptions that cause a function to exit.
1194
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001195- The implementation of set() and frozenset() was revised to use its
1196 own internal data structure. Memory consumption is reduced by 1/3
1197 and there are modest speed-ups as well. The API is unchanged.
1198
Tim Petersde7990b2005-07-17 23:45:23 +00001199- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1200
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001201- SF bug #1229429: PyObject_CallMethod failed to decrement some
1202 reference counts in some error exit cases.
1203
Tim Petersecc6e6a2005-07-10 22:30:55 +00001204- SF bug #1185883: Python's small-object memory allocator took over
1205 a block managed by the platform C library whenever a realloc specified
1206 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001207 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001208 portable way to copy data from the C-managed block into Python's
1209 small-object space without risking a memory fault. Python's small-object
1210 realloc now leaves such blocks under the control of the platform C
1211 realloc.

Michael W. Hudsonb8963812005-07-05 15:21:58 +00001213- SF bug #1232517: An overflow error was not detected properly when
1214 attempting to convert a large float to an int in os.utime().
1215
Raymond Hettinger3296e692005-06-29 23:29:56 +00001216- SF bug #1224347: hex longs now print with lowercase letters just
1217 like their int counterparts.
1218
Michael W. Hudson188d4362005-06-20 16:52:57 +00001219- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1220 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1221 interpreter states; back out that fix and do a better job (see
1222 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1223 for a longer write-up of the problem).
1224
Michael W. Hudsondf888462005-06-03 14:41:55 +00001225- SF patch #1180995: marshal now uses a binary format by default when
1226 serializing floats.
1227
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001228- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1229 the routines that promise to produce IEEE 754 binary representations
1230 of floats now simply copy bytes around.
1231
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001232- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1233 278.
1234
Brett Cannonc3647ac2005-04-26 03:45:26 +00001235- patch #1109424: int, long, float, complex, and unicode now check for the
1236 proper magic slot for type conversions when subclassed. Previously the
1237 magic slot was ignored during conversion. Semantics now match the way
1238 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001239 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001240 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001241 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001242
Barry Warsawc8d907c2005-04-19 23:43:40 +00001243- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1244 NULL, now raise an AttributeError when attempting to set or delete the
1245 attribute. Previously a TypeError was raised, but this was inconsistent
1246 with the equivalent pure-Python implementation.
1247
Michael W. Hudson774479c2005-04-18 08:46:17 +00001248- It is now safe to call PyGILState_Release() before
1249 PyEval_InitThreads() (note that if there is reason to believe there
1250 are multiple threads around you still must call PyEval_InitThreads()
1251 before using the Python API; this fix is for extension modules that
1252 have no way of knowing if Python is multi-threaded yet).
1253
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001254- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1255 disabled caused a crash.
1256
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001257- Bug #1165306: instancemethod_new allowed the creation of a method
1258 with im_class == im_self == NULL, which caused a crash when called.
1259
Tim Petersecc6e6a2005-07-10 22:30:55 +00001260- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001261 fixes the crash seen in bug #1165761
1262
Raymond Hettinger96229b12005-03-11 06:49:40 +00001263- Added two new builtins, any() and all().
1264
Brett Cannon409d8f22005-03-05 06:47:57 +00001265- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001266 (e.g., ``class C(): pass`` is no longer a syntax error).
1267 Patch #1176012 added support to the 'parser' module and 'compiler' package
1268 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001269
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001270- Patch #1115086: Support PY_LONGLONG in structmember.
1271
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001272- Bug #1155938: new style classes did not check that __init__() was
1273 returning None.
1274
Tim Petersecc6e6a2005-07-10 22:30:55 +00001275- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001276 ('\') with a specific error message.
1277
Martin v. Löwisff232d72005-03-03 09:24:38 +00001278- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1279
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001280- Bug #1124295: the __name__ attribute of file objects was
1281 inadvertently made inaccessible in restricted mode.
1282
Tim Petersecc6e6a2005-07-10 22:30:55 +00001283- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001284 an ferror() call.
1285
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001286- min() and max() now support key= arguments with the same meaning as in
1287 list.sort().
1288
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001289- The peephole optimizer now performs simple constant folding in expressions:
1290 (2+3) --> (5).
1291
Raymond Hettingera422c342005-01-11 03:03:27 +00001292- set and frozenset objects can now be marshalled. SF #1098985.
1293
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001294- Bug #1077106: Poor argument checking could cause memory corruption
1295 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001296
Jeremy Hyltonab630502005-02-04 18:44:06 +00001297- The parser did not complain about future statements in illegal
1298 positions. It once again reports a syntax error if a future
1299 statement occurs after anything other than a doc string.
1300
Neil Schemenauercf52c072005-08-12 17:34:58 +00001301- Change the %s format specifier for str objects so that it returns a
1302 unicode instance if the argument is not an instance of basestring and
1303 calling __str__ on the argument returns a unicode instance.
1304
Tim Petersf4e69282006-02-27 17:15:31 +00001305- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1306 current thread state when the auto-GIL-state machinery knows about
1307 it (since the thread state is being deleted, continuing to remember it
1308 can't help, but can hurt if another thread happens to get created with
1309 the same thread id).
1310
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001311Extension Modules

1336
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001337- The unicodedata module was updated to the 4.1 version of the Unicode

1339 for applications that require this specific version (such as IDNA).
1340
Neal Norwitzb62c4332006-03-04 18:35:47 +00001341- The timing module is no longer built by default. It was deprecated

1484
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001485- the cPickle module no longer accepts the deprecated None option in the
1486 args tuple returned by __reduce__().
1487
Raymond Hettingerb2594052004-12-05 09:25:51 +00001488- itertools.islice() now accepts None for the start and step arguments.
1489 This allows islice() to work more readily with slices:
1490 islice(s.start, s.stop, s.step)
1491
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001492- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001501- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1502 been renamed to have only a single underscore prefix. This was done to
1503 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001504
Nick Coghlan43832302006-04-23 17:04:07 +00001505- PEP 338: new module runpy defines a run_module function to support
1506 executing modules which provide access to source code or a code object
1507 via the PEP 302 import mechanisms.
1508
Anthony Baxter93f5b932006-04-03 08:05:07 +00001509- The email module's parsedate_tz function now sets the daylight savings
1510 flag to -1 (unknown) since it can't tell from the date whether it should

1517 in attribute values.
1518
Anthony Baxterc51ee692006-04-01 00:57:31 +00001519- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001520 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001521 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001522 module will not be built.
1523
Tim Petersc17976e2006-04-01 00:26:53 +00001524- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1525 aren't officially supported here, and trying to use them will probably
1526 raise an exception some day. But dicts have been allowed, and "mostly
1527 worked", so support for them won't go away without warning.
1528
Georg Brandl338ef7d2006-03-31 18:42:16 +00001529- Bug #1445068: getpass.getpass() can now be given an explicit stream
1530 argument to specify where to write the prompt.
1531
Georg Brandl22ec80b2006-03-31 18:25:44 +00001532- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1541 to make it easier to monitor when daemon threads have completed
1542 processing all enqueued tasks. Patch #1455676.
1543
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001544- popen2.Popen objects now preserve the command in a .cmd attribute.

1547
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001548- email 4.0 package now integrated. This is largely the same as the email 3.0
1549 package that was included in Python 2.3, except that PEP 8 module names are
1550 now used (e.g. mail.message instead of email.Message). The MIME classes
1551 have been moved to a subpackage (e.g. email.mime.text instead of
1552 email.MIMEText). The old names are still supported for now. Several
1553 deprecated Message methods have been removed and lots of bugs have been
1554 fixed. More details can be found in the email package documentation.
1555
Walter Dörwald40108c92006-03-27 08:15:44 +00001556- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1557 (a subclass of tuple) that provides incremental decoders and encoders
1558 (a way to use stateful codecs without the stream API). Python functions
1559 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1560 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1561 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001562
Walter Dörwald067db482006-03-15 22:17:27 +00001563- Patch #1359365: Calling next() on a closed StringIO.String object raises
1564 a ValueError instead of a StopIteration now (like file and cString.String do).
1565 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1566 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001567
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001568- A regrtest option -w was added to re-run failed tests in verbose mode.

1641 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1642 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1643 Ronald L. Rivest offered this advice for Python:
1644
1645 "The consensus of researchers in this area (at least as
1646 expressed at the NIST Hash Function Workshop 10/31/05),
1647 is that SHA-256 is a good choice for the time being, but
1648 that research should continue, and other alternatives may
1649 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001650
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001651- Added a subset of Fredrik Lundh's ElementTree package. Available

Raymond Hettinger68c04532005-06-10 11:05:19 +00001746- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001747 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001748 the generate_tokens() function now accepts a callable argument that
1749 terminates by raising StopIteration.

1755
Skip Montanaro174dd222005-05-14 20:54:16 +00001756- Patch #1120353: The xmlrpclib module provides better, more transparent,
1757 support for datetime.{datetime,date,time} objects. With use_datetime set
1758 to True, applications shouldn't have to fiddle with the DateTime wrapper
1759 class at all.

Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001761- distutils.commands.upload was added to support uploading distribution
1762 files to PyPI.
1763
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001764- distutils.commands.register now encodes the data as UTF-8 before posting
1765 them to PyPI.
1766
Raymond Hettinger267b8682005-03-27 10:47:39 +00001767- decimal operator and comparison methods now return NotImplemented
1768 instead of raising a TypeError when interacting with other types. This
1769 allows other classes to implement __radd__ style methods and have them
1770 work as expected.
1771
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001772- Bug #1163325: Decimal infinities failed to hash. Attempting to

1809
Guido van Rossumd0641422005-02-03 15:01:24 +00001810- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1811 disables recursive traversal through instance attributes, which can
1812 be exploited in various ways.
1813
Tim Peterse3547fd2005-12-16 23:13:57 +00001814- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001815 flags on the HTTP listening socket.
1816
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001817- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1818 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1819
Fred Drakefbdeaad2006-07-29 16:56:15 +00001820- Patches #893642, #1039083: add allow_none, encoding arguments to

1826
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001827- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1828
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001829- Enhancements to the csv module:
1830
1831 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001832 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001833 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001834 + Dialect parameter parsing has been re-implemented to improve error
1835 reporting.
1836 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1837 dictates.
1838 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001839 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001840 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001841 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1842 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001843 + reader now allows \r characters to be quoted (previously it only allowed
1844 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001845 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001846 + Dialect classes passed to the module are no longer instantiated by
1847 the module before being parsed (the former validation scheme required
1848 this, but the mechanism was unreliable).
1849 + The dialect registry now contains instances of the internal
1850 C-coded dialect type, rather than references to python objects.
1851 + the internal c-coded dialect type is now immutable.
1852 + register_dialect now accepts the same keyword dialect specifications
1853 as the reader and writer, allowing the user to register dialects
1854 without first creating a dialect class.
1855 + a configurable limit to the size of parsed fields has been added -
1856 previously, an unmatched quote character could result in the entire
1857 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001858 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001859 the parser field size limit (returning the former limit). The initial
1860 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001861 + A line_num attribute has been added to the reader object, which tracks
1862 the number of lines read from the source iterator. This is not
1863 the same as the number of records returned, as records can span
1864 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001865 + reader and writer objects were not being registered with the cyclic-GC.
1866 This has been fixed.
1867
Brett Cannone6539c42005-01-08 02:43:53 +00001868- _DummyThread objects in the threading module now delete self.__block that is
1869 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1870 lock primitives tend to be limited in number and thus should not be wasted on
1871 a _DummyThread object. Fixes bug #1089632.
1872
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001873- The imghdr module now detects Exif files.
1874
Raymond Hettinger6065d322004-12-20 23:51:53 +00001875- StringIO.truncate() now correctly adjusts the size attribute.
1876 (Bug #951915).
1877
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001878- locale.py now uses an updated locale alias table (built using
1879 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1880 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001881 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001882
Raymond Hettinger3557f422004-12-07 12:02:02 +00001883- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1884
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001885- the pickle module no longer accepts the deprecated None option in the
1886 args tuple returned by __reduce__().
1887
Brett Cannon84667c02004-12-07 03:25:18 +00001888- optparse now optionally imports gettext. This allows its use in setup.py.
1889
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001890- the pickle module no longer uses the deprecated bin parameter.
1891
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001892- the shelve module no longer uses the deprecated binary parameter.
1893
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001894- the pstats module no longer uses the deprecated ignore() method.
1895
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001896- the filecmp module no longer uses the deprecated use_statcache argument.
1897
Raymond Hettinger664347b2004-12-04 21:21:53 +00001898- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1899 extended or overridden by subclasses. Formerly, the subclassed method would
1900 be ignored by the rest of the module. (Bug #1078905).
1901
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001902- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001903 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001904
Walter Dörwald36733692004-12-22 12:50:50 +00001905- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1906 once when a size argument is given. This prevents a buffer overflow in the
1907 tokenizer with very long source lines.
1908
Barry Warsaw538561e2006-01-01 21:48:54 +00001909- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1910 immediately after creating the object, without any intervening
1911 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001912
Skip Montanaro05885812005-01-16 20:48:27 +00001913- The reconvert.quote function can now emit triple-quoted strings. The
1914 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001915
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001916- ``UserString.MutableString`` now supports negative indices in
1917 ``__setitem__`` and ``__delitem__``
1918
Greg Ward40407942005-03-05 02:53:17 +00001919- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1920 correctly.
1921
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001922- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1923 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1924 character even if the user has passed a size parameter to get a proper
1925 line ending. Remove the special handling of a "\r\n" that has been split
1926 between two lines.
1927
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001928- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1929 about illegal code points. The codec now supports PEP 293 style error
1930 handlers.
1931
Walter Dörwald78a78b02005-09-01 12:04:29 +00001932- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001933 from the input stream, so that the output is a byte string in the correct
1934 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001935
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001936- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1937 considering it exactly like a '*'.
1938
Walter Dörwald007f8df2005-10-09 19:42:27 +00001939- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1940 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001941
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001942- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1943
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001944- Patch #1413711: Certain patterns of differences were making difflib
1945 touch the recursion limit.
1946
Walter Dörwald58917a62006-03-31 15:26:22 +00001947- Bug #947906: An object oriented interface has been added to the calendar
1948 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001949 called as a script (e.g. via ``python -mcalendar``). Localized month and
1950 weekday names can be ouput (even if an exotic encoding is used) using
1951 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001952
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001953Build
1954-----
1955

1960
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001961- Build support for Win64-AMD64 was added.
1962
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001963- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1964
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001965- Patch #881820: look for openpty and forkpty also in libbsd.
1966
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001967- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1968 The zlib module is now builtin on Windows.
1969
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001970- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1971
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001972- Bug #1189330: configure did not correctly determine the necessary
1973 value of LINKCC if python was built with GCC 4.0.
1974
Trent Mick8321b422005-07-26 02:29:21 +00001975- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1976 vulnerability in zlib 1.2.1 and 1.2.2.
1977
Brett Cannon08cd5982005-04-24 22:26:38 +00001978- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1979 flags that change binary compatibility. Changes were also made to
1980 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001981 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001982
Bob Ippolitoed233462005-03-29 13:47:59 +00001983- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1984 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1985 no longer exists). This configure patch makes things right.
1986
Martin v. Löwise2713be2005-03-08 15:03:08 +00001987- Bug #1158607: Build with --disable-unicode again.
1988
Brett Cannon46d96232005-02-16 00:07:19 +00001989- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1990 defined. Discovered as a result of not being able to build on OS X.
1991
Brett Cannon516592f2004-12-07 00:42:59 +00001992- setup.py now uses the directories specified in LDFLAGS using the -L option
1993 and in CPPFLAGS using the -I option for adding library and include
1994 directories, respectively, for compiling extension modules against. This has
1995 led to the core being compiled using the values in CPPFLAGS. It also removes
1996 the need for the special-casing of both DarwinPorts and Fink for darwin since
1997 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1998 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1999 Fink, ``-I/opt/local/include`` for DarwinPorts).
2000
Brett Cannon43802422005-02-10 20:48:03 +00002001- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2002 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2003 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.

2007-----
2008
Tim Petersc9d78aa2006-03-26 23:27:58 +00002009- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2010 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2011 is obtained via the ``PyObject_`` family, it must be released via the
2012 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2013 always been officially true, but when Python's small-object allocator was
2014 introduced, an attempt was made to cater to a few extension modules
2015 discovered at the time that obtained memory via ``PyObject_New`` but
2016 released it via ``PyMem_DEL``. It's years later, and if such code still
2017 exists it will fail now (probably with segfaults, but calling wrong
2018 low-level memory management functions can yield many symptoms).
2019
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002020- Added a C API for set and frozenset objects.
2021

2023
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002024- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2025 mapping argument now. This string is used as a mapping table. Byte values
2026 greater than the length of the string and 0xFFFE are treated as undefined
2027 mappings.
