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

66
Neal Norwitzbf8c1952006-08-15 04:14:57 +000067- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
68
Georg Brandl7a1af772006-08-14 21:55:28 +000069- Patch #1536071: trace.py should now find the full module name of a
70 file correctly even on Windows.
71
Georg Brandl0a7d1bb2006-08-11 07:26:10 +000072- logging's atexit hook now runs even if the rest of the module has
73 already been cleaned up.
74
Guido van Rossum133f4e42006-08-10 17:42:50 +000075- Bug #1112549, DoS attack on cgi.FieldStorage.
76
Neal Norwitzff4b63b2006-08-04 04:50:21 +000077- Bug #1531405, format_exception no longer raises an exception if
78 str(exception) raised an exception.
79
Neil Schemenauer06ded092006-08-04 16:20:30 +000080- Fix a bug in the ``compiler`` package that caused invalid code to be
81 generated for nested functions.
82
Neal Norwitzff4b63b2006-08-04 04:50:21 +000083
84Extension Modules
85-----------------
86
Neal Norwitzbf8c1952006-08-15 04:14:57 +000087- Patch #1511317: don't crash on invalid hostname (alias) info.
88
Georg Brandl3335a7a2006-08-14 21:42:55 +000089- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
90 raises the correct exceptions.
91
Thomas Heller1ce433e2006-08-14 16:20:04 +000092- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
93 '-no-stack-protector' compiler flag for OpenBSD has been removed.
94
Thomas Heller86720042006-08-14 11:17:48 +000095- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
96 uses the _as_parameter_ attribute when objects are passed to foreign
97 function calls. The ctypes version number was changed to 1.0.1.
98
Bob Ippolitoe6c9f982006-08-04 23:59:21 +000099- Bug #1530559, struct.pack raises TypeError where it used to convert.
100 Passing float arguments to struct.pack when integers are expected
101 now triggers a DeprecationWarning.
102
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000103

Fred Drake53912162006-07-29 13:22:49 +0000147What's New in Python 2.5 beta 3?
148================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000149
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000150*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000151
152Core and builtins
153-----------------
154
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000155- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t, it previously
156 returned a long (see PEP 353).
157
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000158- Bug #1515471: string.replace() accepts character buffers again.
159
Neal Norwitz07aadb12006-07-30 06:55:48 +0000160- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
161 This provides the proper warning for struct.pack().
162 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
163
Neal Norwitz0d62a062006-07-30 06:53:31 +0000164- Patch #1531113: Fix augmented assignment with yield expressions.
165 Also fix a SystemError when trying to assign to yield expressions.
166
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000167- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
168 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
169 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
170 excessive filesystem operations during imports.
171
Tim Petersbc24eee2006-07-27 01:14:53 +0000172- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
173 operations on signed longs that are formally undefined by C.
174 Unfortunately, at least one compiler now cares about that, so complicated
175 the code to make that compiler happy again.
176
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000177- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
178
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000179- Patch #1232023: Stop including current directory in search
180 path on Windows.
181
Neal Norwitze1fdb322006-07-21 05:32:28 +0000182- Fix some potential crashes found with failmalloc.
183
Neal Norwitze7563102006-07-17 01:00:16 +0000184- Fix warnings reported by Klocwork's static analysis tool.
185
Neal Norwitz84be93b2006-07-16 01:50:38 +0000186- Bug #1512814, Fix incorrect lineno's when code within a function
187 had more than 255 blank lines.
188
Georg Brandl9dceedb2006-07-12 15:31:17 +0000189- Patch #1521179: Python now accepts the standard options ``--help`` and
190 ``--version`` as well as ``/?`` on Windows.
191
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000192- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000193 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000194 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000195
Tim Peters112aad32006-07-19 00:03:19 +0000196- Bug #1524317: Compiling Python ``--without-threads`` failed.
197 The Python core compiles again then, and, in a build without threads, the
198 new ``sys._current_frames()`` returns a dictionary with one entry,
199 mapping the faux "thread id" 0 to the current frame.
200
Ronald Oussoren3075e162006-07-25 20:28:55 +0000201- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000202
Ronald Oussoren3075e162006-07-25 20:28:55 +0000203
Neal Norwitza1f10902006-07-12 07:28:29 +0000204Library
205-------
206
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000207- Correction of patch #1455898: In the mbcs decoder, set final=False
208 for stream decoder, but final=True for the decode function.
209
Georg Brandl07fec3a2006-08-01 18:49:24 +0000210- os.urandom no longer masks unrelated exceptions like SystemExit or
211 KeyboardInterrupt.
212
Tim Peters4643c2f2006-08-10 22:45:34 +0000213- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000214 shutil.copytree on Windows
215
Georg Brandle34ac7c2006-07-30 11:07:23 +0000216- Bug #1002398: The documentation for os.path.sameopenfile now correctly
217 refers to file descriptors, not file objects.
218
Fred Drakefbdeaad2006-07-29 16:56:15 +0000219- Rename of the xml package to xmlcore, and the import hackery done to
220 make it appear at both names, has been removed. Bug #1511497,
221 #1513611, and probably others.
222
Georg Brandledd9b0d2006-07-29 09:33:26 +0000223- Bug #1441397: The compiler module now recognizes module and function
224 docstrings correctly as it did in Python 2.4.
225
Tim Peters6f681472006-07-27 23:44:37 +0000226- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
227 lost that tests are sorted by name before being run. This rarely
228 matters for well-written tests, but can create baffling symptoms if
229 side effects from one test to the next affect outcomes. ``DocTestFinder``
230 has been changed to sort the list of tests it returns.
231
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000232- The distutils version has been changed to 2.5.0, and are now kept
233 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000234
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000235- Bug #978833: Really close underlying socket in _socketobject.close.
236
Georg Brandl0619a322006-07-26 07:40:17 +0000237- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
238 with title().
239
Georg Brandlcf0c1722006-07-26 07:23:32 +0000240- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
241 to recursive calls and call it with the failing package name.
242
Martin v. Löwis0b483032006-07-25 09:53:12 +0000243- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
244
Georg Brandlc13c34c2006-07-24 14:09:56 +0000245- Patch #1515343: Fix printing of deprecated string exceptions with a
246 value in the traceback module.
247
Greg Ward48fae7a2006-07-23 16:05:51 +0000248- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
249
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000250- Patch #1524429: Use repr() instead of backticks in Tkinter again.
251
Brett Cannoncaebe222006-07-18 04:41:36 +0000252- Bug #1520914: Change time.strftime() to accept a zero for any position in its
253 argument tuple. For arguments where zero is illegal, the value is forced to
254 the minimum value that is correct. This is to support an undocumented but
255 common way people used to fill in inconsequential information in the time
256 tuple pre-2.4.
257
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000258- Patch #1220874: Update the binhex module for Mach-O.
259
Barry Warsawb110bad2006-07-21 14:51:07 +0000260- The email package has improved RFC 2231 support, specifically for
261 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
262 (name*0=<blah>) parameter continuations. This may change the types of
263 values returned from email.message.Message.get_param() and friends.
264 Specifically in some cases where non-encoded continuations were used,
265 get_param() used to return a 3-tuple of (None, None, string) whereas now it
266 will just return the string (since non-encoded continuations don't have
267 charset and language parts).
268
269 Also, whereas % values were decoded in all parameter continuations, they are
270 now only decoded in encoded parameter parts.
271
Ronald Oussoren3075e162006-07-25 20:28:55 +0000272- Bug #1517990: IDLE keybindings on MacOS X now work correctly
273
274- Bug #1517996: IDLE now longer shows the default Tk menu when a
275 path browser, class browser or debugger is the frontmost window on MacOS X
276
Barry Warsaw00decd72006-07-27 23:43:15 +0000277- Patch #1520294: Support for getset and member descriptors in types.py,
278 inspect.py, and pydoc.py. Specifically, this allows for querying the type
279 of an object against these built-in types and more importantly, for getting
280 their docstrings printed in the interactive interpreter's help() function.
281
Ronald Oussoren3075e162006-07-25 20:28:55 +0000282
Neal Norwitza1f10902006-07-12 07:28:29 +0000283Extension Modules
284-----------------
285
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000286- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
287 a socket operation on a socket with a timeout, the exception will be
288 caught correctly. Previously, the exception was not caught.
289
Thomas Heller1393d6a2006-07-28 21:43:20 +0000290- Patch #1529514: The _ctypes extension is now compiled on more
291 openbsd target platforms.
292
Tim Peters9cab5932006-07-28 00:30:00 +0000293- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
294 a memory leak, affecting pickles and deep copies.
295
Tim Petersbc24eee2006-07-27 01:14:53 +0000296- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000297 Paul Eggert.
298
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000299- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
300
Thomas Hellerce049a02006-07-14 17:51:14 +0000301- Patch #1521817: Index range checking on ctypes arrays containing
302 exactly one element enabled again. This allows iterating over these
303 arrays, without the need to check the array size before.
304
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000305- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000306 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000307 /dev/null in certain cases; this is now fixed.
308
Thomas Heller47d7a062006-07-12 08:43:47 +0000309- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
310 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000311
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000312- Because of a misspelled preprocessor symbol, ctypes was always
313 compiled without thread support; this is now fixed.

Gregory P. Smith641cddf2006-07-28 01:35:25 +0000315- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
316 methods now allow their database parameter to be None as the
317 sleepycat API allows.
318
Matt Flemingec926502006-07-28 11:27:27 +0000319- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
320 bluetooth API compared with Linux and FreeBSD.
321
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000322Tests
323-----
324
325- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
326 how long the test file should take to play. Now accepts taking 2.93 secs
327 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
328
Georg Brandl4793aa32006-07-28 18:31:39 +0000329- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
330 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
331 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000338Mac
339---
340
341- PythonLauncher now works correctly when the path to the script contains
342 characters that are treated specially by the shell (such as quotes).
343
344- Bug #1527397: PythonLauncher now launches scripts with the working directory
345 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000346 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000347 expect.

355Core and builtins
356-----------------
357
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000358- Bug #1441486: The literal representation of -(sys.maxint - 1)
359 again evaluates to a int object, not a long.
360
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000361- Bug #1501934: The scope of global variables that are locally assigned
362 using augmented assignment is now correctly determined.
363
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000364- Bug #927248: Recursive method-wrapper objects can now safely
365 be released.
366
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000367- Bug #1417699: Reject locale-specific decimal point in float()
368 and atof().
369
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000370- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
371 omit a default "error" argument for NULL pointer. This allows
372 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000373
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000374- Bug #1519018: 'as' is now validated properly in import statements.
375
Neal Norwitz28746ab2006-07-09 22:14:42 +0000376- On 64 bit systems, int literals that use less than 64 bits are
377 now ints rather than longs.
378
Neal Norwitzed657552006-07-10 00:04:44 +0000379- Bug #1512814, Fix incorrect lineno's when code at module scope
380 started after line 256.
381
Tim Peters32a83612006-07-10 21:08:24 +0000382- New function ``sys._current_frames()`` returns a dict mapping thread
383 id to topmost thread stack frame. This is for expert use, and is
384 especially useful for debugging application deadlocks. The functionality
385 was previously available in Fazal Majid's ``threadframe`` extension
386 module, but it wasn't possible to do this in a wholly threadsafe way from
387 an extension.

396
Tim Peters32a83612006-07-10 21:08:24 +0000397- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000398 environment variable to be set in order to the SDK environment
399 for finding the compiler, include files, etc.

404
Thomas Woutersadd19112006-07-05 11:03:49 +0000405- string.Template() now correctly handles tuple-values. Previously,
406 multi-value tuples would raise an exception and single-value tuples would
407 be treated as the value they contain, instead.
408
Martin v. Löwisede77f52006-07-03 13:01:35 +0000409- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
410 even if some data are received.
411
Martin v. Löwis45482392006-07-03 12:28:58 +0000412- Bug #1267547: Put proper recursive setup.py call into the

416 degrees and radians.
417
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000418- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000419 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000420
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000421- Bug #1514703: Only setup canvas window in turtle when the canvas
422 is created.
423
Martin v. Löwis7596e832006-07-01 15:33:37 +0000424- Bug #1513223: .close() of a _socketobj now releases the underlying
425 socket again, which then gets closed as it becomes unreferenced.
426
Fred Drake10497c82006-06-29 02:57:48 +0000427- Bug #1504333: Make sgmllib support angle brackets in quoted
428 attribute values.
429
430- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
431 sgmllib ('[' and ']' were not accepted).
432
Georg Brandl1be63af2006-06-28 20:23:25 +0000433- Fix a bug in the turtle module's end_fill function.
434
Brett Cannon53ab5b72006-06-22 16:49:14 +0000435- Bug #1510580: The 'warnings' module improperly required that a Warning
436 category be either a types.ClassType and a subclass of Warning. The proper
437 check is just that it is a subclass with Warning as the documentation states.
438
Georg Brandlad29e632006-06-21 17:45:17 +0000439- The compiler module now correctly compiles the new try-except-finally
440 statement (bug #1509132).
441
Neal Norwitz60373cd2006-06-22 06:30:50 +0000442- The wsgiref package is now installed properly on Unix.
443
Vinay Sajip28e57612006-07-01 10:45:20 +0000444- A bug was fixed in logging.config.fileConfig() which caused a crash on
445 shutdown when fileConfig() was called multiple times.
446
Gerhard Häring762fbd32006-07-02 17:48:30 +0000447- The sqlite3 module did cut off data from the SQLite database at the first
448 null character before sending it to a custom converter. This has been fixed
449 now.
450
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000451Extension Modules
452-----------------
453
Tim Peters112aad32006-07-19 00:03:19 +0000454- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
455 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
456 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000457
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000458- Assigning None to pointer type fields in ctypes structures possible
459 overwrote the wrong fields, this is fixed now.
460
461- Fixed a segfault in _ctypes when ctypes.wintypes were imported
462 on non-Windows platforms.
463
464- Bug #1518190: The ctypes.c_void_p constructor now accepts any
465 integer or long, without range checking.
466
467- Patch #1517790: It is now possible to use custom objects in the ctypes
468 foreign function argtypes sequence as long as they provide a from_param
469 method, no longer is it required that the object is a ctypes type.
470
471- The '_ctypes' extension module now works when Python is configured
472 with the --without-threads option.
473
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000474- Bug #1513646: os.access on Windows now correctly determines write
475 access, again.
476
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000477- Bug #1512695: cPickle.loads could crash if it was interrupted with
478 a KeyboardInterrupt.
479
Neal Norwitza12aa882006-07-06 06:45:08 +0000480- Bug #1296433: parsing XML with a non-default encoding and
481 a CharacterDataHandler could crash the interpreter in pyexpat.
482
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000483- Patch #1516912: improve Modules support for OpenVMS.
484
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000485Build
486-----
487
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000488- Automate Windows build process for the Win64 SSL module.
489
Tim Peters32a83612006-07-10 21:08:24 +0000490- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000491 Previously, the slight difference could cause compilation errors of the
492 'zlib' module on systems with more than one version of zlib.
493
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000494- The MSI compileall step was fixed to also support a TARGETDIR
495 with spaces in it.
496
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000497- Bug #1517388: sqlite3.dll is now installed on Windows independent
498 of Tcl/Tk.
499
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000500- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000501 trying to be installed even though it's empty.

504-----
505
506- Call os.waitpid() at the end of tests that spawn child processes in order
507 to minimize resources (zombies).
508
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000509Documentation
510-------------
511
Nick Coghlan2d792252006-07-06 13:47:18 +0000512- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
513 documentation for the warnings module.
514
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000515- Patch #1509163: MS Toolkit Compiler no longer available.
516

Anthony Baxter51bcb682006-04-05 14:51:42 +0000524
525Core and builtins
526-----------------
527
Georg Brandla56b9152006-06-19 06:35:54 +0000528- Patch #1507676: Error messages returned by invalid abstract object operations
529 (such as iterating over an integer) have been improved and now include the
530 type of the offending object to help with debugging.
531
Brett Cannonea3912b2006-06-13 21:46:41 +0000532- Bug #992017: A classic class that defined a __coerce__() method that returned
533 its arguments swapped would infinitely recurse and segfault the interpreter.
534
Neal Norwitz909eb122006-06-12 02:13:21 +0000535- Fix the socket tests so they can be run concurrently.
536
Neal Norwitzb9845e72006-06-12 02:11:18 +0000537- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000538 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000539
Brett Cannon22565aa2006-06-09 22:31:23 +0000540- Bug #532646: object.__call__() will continue looking for the __call__
541 attribute on objects until one without one is found. This leads to recursion
542 when you take a class and set its __call__ attribute to an instance of the
543 class. Originally fixed for classic classes, but this fix is for new-style.
544 Removes the infinite_rec_3 crasher.
545
Georg Brandl24250812006-06-09 18:45:48 +0000546- The string and unicode methods startswith() and endswith() now accept
547 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
548
Brett Cannonde3b0522006-06-08 17:00:45 +0000549- Buffer objects, at the C level, never used the char buffer
550 implementation even when the char buffer for the wrapped object was
551 explicitly requested (originally returned the read or write buffer).
552 Now a TypeError is raised if the char buffer is not present but is
553 requested.
554
Georg Brandlddbaa662006-06-04 21:56:52 +0000555- Patch #1346214: Statements like "if 0: suite" are now again optimized
556 away like they were in Python 2.4.
557
Georg Brandlb7c8f542006-05-27 12:30:25 +0000558- Builtin exceptions are now full-blown new-style classes instead of
559 instances pretending to be classes, which speeds up exception handling
560 by about 80% in comparison to 2.5a2.
561
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000562- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
563 Unicode 4.1.
564
Georg Brandlf4ef1162006-05-26 18:03:31 +0000565- Patch #921466: sys.path_importer_cache is now used to cache valid and
566 invalid file paths for the built-in import machinery which leads to
567 fewer open calls on startup.
568
Tim Peters696cf432006-05-24 21:10:40 +0000569- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
570 of-2 bases. The largest speedup is for inputs with about 1000 decimal
571 digits. Conversion from non-power-of-2 bases remains quadratic-time in
572 the number of input digits (it was and remains linear-time for bases
573 2, 4, 8, 16 and 32).
574
Tim Petersb713ec22006-05-23 18:45:30 +0000575- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
576 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
577 an integer close to ``sys.maxint``. This was repaired by patch
578 #1335972, which also gives a nice speedup.
579
Richard Jonescebbefc2006-05-23 18:28:17 +0000580- Patch #1337051: reduced size of frame objects.
581
582- PyErr_NewException now accepts a tuple of base classes as its
583 "base" parameter.
584
Richard Jones7c88dcc2006-05-23 10:37:38 +0000585- Patch #876206: function call speedup by retaining allocated frame
586 objects.
587
Georg Brandl7b90e162006-05-18 07:01:27 +0000588- Bug #1462152: file() now checks more thoroughly for invalid mode
589 strings and removes a possible "U" before passing the mode to the
590 C library function.
591
Neal Norwitz1004a532006-05-15 07:17:23 +0000592- Patch #1488312, Fix memory alignment problem on SPARC in unicode
593
Neal Norwitz373f0a72006-05-15 07:04:36 +0000594- Bug #1487966: Fix SystemError with conditional expression in assignment
595
Martin v. Löwis879768d2006-05-11 13:28:43 +0000596- WindowsError now has two error code attributes: errno, which carries
597 the error values from errno.h, and winerror, which carries the error
598 values from winerror.h. Previous versions put the winerror.h values
599 (from GetLastError()) into the errno attribute.
600
Martin v. Löwis77736712006-05-04 05:51:03 +0000601- Patch #1475845: Raise IndentationError for unexpected indent.
602
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000603- Patch #1479181: split open() and file() from being aliases for each other.
604
Tim Peters44bd9862006-06-01 13:49:23 +0000605- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
606 methods were always silently ignored by dictionaries when comparing keys.
607 They are now passed through (except when using the C API function
608 ``PyDict_GetItem()``, whose semantics did not change).
609
610- Bug #1456209: In some obscure cases it was possible for a class with a
611 custom ``__eq__()`` method to confuse dict internals when class instances
612 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
613 No, you don't have any code that did this ;-)

619
620- Patch #1462338: Upgrade pyexpat to expat 2.0.0
621
Brett Cannon6ee7d012006-06-08 16:23:04 +0000622- Change binascii.hexlify to accept a read-only buffer instead of only a char
623 buffer and actually follow its documentation.
624
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000625- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
626
Nick Coghlanc649ec52006-05-29 12:43:05 +0000627- Patch #1478788 (modified version): The functional extension module has
628 been renamed to _functools and a functools Python wrapper module added.
629 This provides a home for additional function related utilities that are
630 not specifically about functional programming. See PEP 309.
631
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000632- Patch #1493701: performance enhancements for struct module.
633
Georg Brandl378d5922006-05-17 14:26:50 +0000634- Patch #1490224: time.altzone is now set correctly on Cygwin.
635
Georg Brandl8d3342b2006-05-16 07:38:27 +0000636- Patch #1435422: zlib's compress and decompress objects now have a
637 copy() method.
638
Andrew MacIntyre92913322006-06-13 15:04:24 +0000639- Patch #1454481: thread stack size is now tunable at runtime for thread
640 enabled builds on Windows and systems with Posix threads support.
641
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000642- On Win32, os.listdir now supports arbitrarily-long Unicode path names
643 (up to the system limit of 32K characters).
644
645- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
646 As a result, these functions now raise WindowsError instead of OSError.
647
Tim Peters7a822da2006-05-25 21:50:17 +0000648- ``time.clock()`` on Win64 should use the high-performance Windows
649 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
650 Windows platforms).
651
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000652- Calling Tk_Init twice is refused if the first call failed as that
653 may deadlock.
654
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000655- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
656 accept it without potentially using an uninitialized pointer.
657
658- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
659 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
660 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000661
Gregory P. Smith372b5832006-06-05 18:48:21 +0000662- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000663 [pybsddb project SF patch number 1466734]
664
Gregory P. Smith372b5832006-06-05 18:48:21 +0000665- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
666 parameter is supplied. [SF pybsddb bug #1477863]
667
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000668- bsddb: the __len__ method of a DB object has been fixed to return correct
669 results. It could previously incorrectly return 0 in some cases.
670 Fixes SF bug 1493322 (pybsddb bug 1184012).
671
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000672- bsddb: the bsddb.dbtables Modify method now raises the proper error and
673 aborts the db transaction safely when a modifier callback fails.
674 Fixes SF python patch/bug #1408584.
675
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000676- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000677 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000678 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
679 database calls that would previously deadlock. [SF python bug #775414]
680
Vinay Sajip28e57612006-07-01 10:45:20 +0000681- Patch #1446489: add support for the ZIP64 extensions to zipfile.

704
Georg Brandl2605ca82006-06-14 06:08:31 +0000705- Bug #1339007: Shelf objects now don't raise an exception in their
706 __del__ method when initialization failed.
707
Martin v. Löwisd8251432006-06-14 05:21:04 +0000708- Patch #1455898: The MBCS codec now supports the incremental mode for
709 double-byte encodings.
710
Tim Peters43898b42006-06-14 04:09:25 +0000711- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
712 guarantee that adjacent triples in the return list always describe
713 non-adjacent blocks. Previously, a pair of matching blocks could end
714 up being described by multiple adjacent triples that formed a partition
715 of the matching pair.
716
Greg Ward0e0c9f42006-06-11 16:24:11 +0000717- Bug #1498146: fix optparse to handle Unicode strings in option help,
718 description, and epilog.
719
Greg Wardd1c797e2006-06-11 14:42:41 +0000720- Bug #1366250: minor optparse documentation error.

723 clarify docs.
724
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000725- The wsgiref package has been added to the standard library.
726
Nick Coghlan676725d2006-06-08 13:54:49 +0000727- The functions update_wrapper() and wraps() have been added to the functools
728 module. These make it easier to copy relevant metadata from the original
729 function when writing wrapper functions.
730
Tim Petersd6a9eef2006-06-05 01:48:21 +0000731- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
732 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000733
Martin v. Löwis3f767792006-06-04 19:36:28 +0000734- Patch #1359618: Speed up charmap encoder by using a trie structure
735 for lookup.
736
Tim Petersd609b1a2006-06-02 23:22:51 +0000737- The functions in the ``pprint`` module now sort dictionaries by key
738 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
739 if and only if its display required more than one line, although that
740 wasn't documented. The new behavior increases predictability; e.g.,
741 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
742
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000743- Patch #1497027: try HTTP digest auth before basic auth in urllib2

747 default HTTP and HTTPS ports.
748
George Yoshidaf3c65de2006-05-28 16:39:09 +0000749- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.

Bob Ippolito7298f272006-05-23 18:43:47 +0000751- Patch #1281707: speed up gzip.readline.
752
Georg Brandlb89316f2006-05-17 15:51:16 +0000753- Patch #1180296: Two new functions were added to the locale module:
754 format_string() to get the effect of "format % items" but locale-aware,
755 and currency() to format a monetary number with currency sign.
756
Georg Brandle3a25832006-05-17 14:56:04 +0000757- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
758 and several features added, such as speed and geometry control.
759
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000760- Patch #1488881: add support for external file objects in bz2 compressed
761 tarfiles.
762
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000763- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
764 stdout arguments, making it possible to redirect input and output
765 for remote debugging.
766
767- Patch #1484695: Update the tarfile module to version 0.8. This fixes
768 a couple of issues, notably handling of long file names using the
769 GNU LONGNAME extension.
770
771- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
772 new flag when ``name`` is already the name of an option flag.
773
774- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
775 package.

817
818Core and builtins
819-----------------
820
Thomas Heller1b046642006-04-18 18:51:06 +0000821- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
822 by converting these apis from macros into exported functions again:
823
824 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
825 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
826 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
827 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
828 PyRun_String Py_CompileString
829
Martin v. Löwis45294a92006-04-18 06:24:08 +0000830- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
831
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000832- All uses of PyStructSequence_InitType have been changed to initialize
833 the type objects only once, even if the interpreter is initialized
834 multiple times.
835
Neal Norwitz61546162006-04-14 05:20:28 +0000836- Bug #1454485, array.array('u') could crash the interpreter. This was
837 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
838 to unicode when it didn't make sense. 'u#' now requires a unicode string.
839
840- Py_UNICODE is unsigned. It was always documented as unsigned, but
841 due to a bug had a signed value in previous versions.
842
Tim Peters3a5e8b12006-04-11 01:44:07 +0000843- Patch #837242: ``id()`` of any Python object always gives a positive
844 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
845 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000846 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000847 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000848
Tim Peters3a5e8b12006-04-11 01:44:07 +0000849 def __hash__(self):
850 return id(self) # WRONG
851
852 because a hash result must be a (short) Python int but it was always
853 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000854 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000855 was always usable as a hash value before this patch. That's no longer
856 necessarily so.
857
858- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000859 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000860 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000861 #1454844)
862
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000863- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
864 involving generators that have paused outside of any ``try`` or ``with``
865 blocks. (In 2.5a1, a paused generator that was part of a reference
866 cycle could not be garbage collected, regardless of whether it was
867 paused in a ``try`` or ``with`` block.)

884 a temporary db (file=None) with the 'n' flag to truncate on open.
885
886- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
887 as older versions cause excessive test failures.

893-------
894
Peter Astrand7d1d4362006-07-14 14:04:45 +0000895- Bug #1223937: subprocess.CalledProcessError reports the exit status
896 of the process using the returncode attribute, instead of
897 abusing errno.
898
Tim Peters711bf302006-04-25 03:31:36 +0000899- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
900 a doctest to be skipped (the code is not run, and the expected output
901 or exception is ignored).
902
Nick Coghlanda2268f2006-04-24 04:37:15 +0000903- Fixed contextlib.nested to cope with exceptions being raised and
904 caught inside exit handlers.
905
Greg Wardab05edc2006-04-23 03:47:58 +0000906- Updated optparse module to Optik 1.5.1 (allow numeric constants in
907 hex, octal, or binary; add ``append_const`` action; keep going if
908 gettext cannot be imported; added ``OptionParser.destroy()`` method;
909 added ``epilog`` for better help generation).
910
Tim Peters21fbd572006-04-21 21:18:10 +0000911- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
912 called from a thread spawned as a side effect of importing a module.
913
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000914- The pydoc module now supports documenting packages contained in
915 .zip or .egg files.
916
917- The pkgutil module now has several new utility functions, such
918 as ``walk_packages()`` to support working with packages that are either
919 in the filesystem or zip files.
920
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000921- The mailbox module can now modify and delete messages from
922 mailboxes, in addition to simply reading them. Thanks to Gregory
923 K. Johnson for writing the code, and to the 2005 Google Summer of
924 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000925
Tim Petersc7605f22006-04-17 21:12:33 +0000926- The ``__del__`` method of class ``local`` in module ``_threading_local``
927 returned before accomplishing any of its intended cleanup.
928
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000929- Patch #790710: Add breakpoint command lists in pdb.

934
Anthony Baxtere29002c2006-04-12 12:07:31 +0000935- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
936 Windows. Bug #1469163.
937
Phillip J. Eby47032112006-04-11 01:07:43 +0000938- The warnings, linecache, inspect, traceback, site, and doctest modules
939 were updated to work correctly with modules imported from zipfiles or

953-----
954
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000955- The Makefile now has a reindent target, which runs reindent.py on
956 the library.
957

Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000961
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000962- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
963 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000964 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000965 CXX from --with-cxx-main, see description in README.
966
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000967- Patch #1429775: Link extension modules with the shared libpython.
968
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000969- Fixed a libffi build problem on MIPS systems.
970
Tim Peters8931ff12006-05-13 23:28:20 +0000971- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
972 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
973 and "%zu" for unsigned integers of type ``size_t``.
974
Anthony Baxter51bcb682006-04-05 14:51:42 +0000975Tests
976-----
977
Nick Coghlanda2268f2006-04-24 04:37:15 +0000978- test_contextlib now checks contextlib.nested can cope with exceptions
979 being raised and caught inside exit handlers.
980
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000981- test_cmd_line now checks operation of the -m and -c command switches
982
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000983- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
984 it separately and by hand. It also wasn't cleaning up its changes to
985 the current Decimal context.
986
Thomas Woutersabd08882006-04-26 15:53:30 +0000987- regrtest.py now has a -M option to run tests that test the new limits of
988 containers, on 64-bit architectures. Running these tests is only sensible
989 on 64-bit machines with more than two gigabytes of memory. The argument
990 passed is the maximum amount of memory for the tests to use.

999-------------
1000
Tim Petersb06d28c2006-05-12 01:57:59 +00001001- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1002
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001003- PEP 343: Added Context Types section to the library reference
1004 and attempted to bring other PEP 343 related documentation into
1005 line with the implementation and/or python-dev discussions.
1006
Tim Peters8dc73d22006-04-24 02:03:16 +00001007- Bug #1337990: clarified that ``doctest`` does not support examples
1008 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001011What's New in Python 2.5 alpha 1?
1012=================================
1013
Anthony Baxterebed3f62006-04-03 15:03:44 +00001014*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001015
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001016Core and builtins
1017-----------------
1018
Nick Coghlan43832302006-04-23 17:04:07 +00001019- PEP 338: -m command line switch now delegates to runpy.run_module
1020 allowing it to support modules in packages and zipfiles
1021
Martin v. Löwisc661b882006-04-20 04:54:23 +00001022- On Windows, .DLL is not an accepted file name extension for
1023 extension modules anymore; extensions are only found if they
1024 end in .PYD.
1025
Martin v. Löwisea62d252006-04-03 10:56:49 +00001026- Bug #1421664: sys.stderr.encoding is now set to the same value as
1027 sys.stdout.encoding.
1028
Neal Norwitz92e212f2006-04-03 04:48:37 +00001029- __import__ accepts keyword arguments.
1030
Georg Brandlccadf842006-03-31 18:54:53 +00001031- Patch #1460496: round() now accepts keyword arguments.
1032
Anthony Baxter262c00a2006-03-30 10:53:17 +00001033- Fixed bug #1459029 - unicode reprs were double-escaped.
1034
Hye-Shik Changd478f342006-03-23 12:32:36 +00001035- Patch #1396919: The system scope threads are reenabled on FreeBSD
1036 5.4 and later versions.
1037
Neal Norwitze98ccf62006-03-23 05:39:47 +00001038- Bug #1115379: Compiling a Unicode string with an encoding declaration
1039 now gives a SyntaxError.
1040
Georg Brandlabd1ff82006-03-18 07:59:59 +00001041- Previously, Python code had no easy way to access the contents of a
1042 cell object. Now, a ``cell_contents`` attribute has been added
1043 (closes patch #1170323).
1044
Tim Peterscf79aac2006-03-16 01:14:46 +00001045- Patch #1123430: Python's small-object allocator now returns an arena to
1046 the system ``free()`` when all memory within an arena becomes unused
1047 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1048 freed. Some applications will see a drop in virtual memory size now,
1049 especially long-running applications that, from time to time, temporarily
1050 use a large number of small objects. Note that when Python returns an
1051 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001052 platform C library will in turn return that memory to the operating system.
1053 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001054 appears to be effective at least on Microsoft C and gcc-based systems.
1055 Thanks to Evan Jones for hard work and patience.
1056
Georg Brandl533ff6f2006-03-08 18:09:27 +00001057- Patch #1434038: property() now uses the getter's docstring if there is
1058 no "doc" argument given. This makes it possible to legitimately use
1059 property() as a decorator to produce a read-only property.
1060
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001061- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1062 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1063 of requiring an int or long in slicing and a few other contexts, enabling
1064 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1065
Neal Norwitz995acdf2006-03-07 05:01:00 +00001066- Fixed various bugs reported by Coverity's Prevent tool.
1067
Brett Cannonbf364092006-03-01 04:25:17 +00001068- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1069 new exception base class, BaseException, which has a new message attribute.
1070 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1071 Raising a string exception now raises a DeprecationWarning.
1072
Thomas Woutersfb609f42006-02-28 16:37:25 +00001073- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1074 explicitly relative, using 'from .module import name' to mean 'from the same
1075 package as this module is in. Imports without dots still default to the
1076 old relative-then-absolute, unless 'from __future__ import
1077 absolute_import' is used.
1078
Brett Cannona7446e32006-02-27 23:39:10 +00001079- Properly check if 'warnings' raises an exception (usually when a filter set
1080 to "error" is triggered) when raising a warning for raising string
1081 exceptions.
1082
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001083- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001084 The name was removed from Include/code.h.
1085
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001086- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001087
Guido van Rossum1968ad32006-02-25 22:38:04 +00001088- Patch 1433928:
1089 - The copy module now "copies" function objects (as atomic objects).
1090 - dict.__getitem__ now looks for a __missing__ hook before raising
1091 KeyError.
1092
Tim Peters84ef21c2006-02-28 20:39:06 +00001093- PEP 343: with statement implemented. Needs ``from __future__ import
1094 with_statement``. Use of 'with' as a variable will generate a warning.
1095 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001096 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001097 The following objects have __context__ methods:
1098 - The built-in file type.
1099 - The thread.LockType type.
1100 - The following types defined by the threading module:
1101 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1102 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001103
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001104- Fix the encodings package codec search function to only search
1105 inside its own package. Fixes problem reported in patch #1433198.
1106
1107 Note: Codec packages should implement and register their own
1108 codec search function. PEP 100 has the details.
1109
Tim Peters9ea89d22006-06-04 03:26:02 +00001110- PEP 353: Using ``Py_ssize_t`` as the index type.
1111
1112- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1113 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1114 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1115 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1116 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001117
Neal Norwitzfc76d632006-01-10 06:03:13 +00001118- Patch #1400181, fix unicode string formatting to not use the locale.
1119 This is how string objects work. u'%f' could use , instead of .
1120 for the decimal point. Now both strings and unicode always use periods.
1121
Neal Norwitz671b9e32006-01-09 07:07:12 +00001122- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1123 configure would break checking curses.h.
1124
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001125- Bug #959576: The pwd module is now builtin. This allows Python to be
1126 built on UNIX platforms without $HOME set.
1127
Neal Norwitzc10978f2005-12-19 06:07:16 +00001128- Bug #1072182, fix some potential problems if characters are signed.
1129
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001130- Bug #889500, fix line number on SyntaxWarning for global declarations.
1131
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001132- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1133
Neal Norwitze7214a12005-12-18 05:03:17 +00001134- Support for converting hex strings to floats no longer works.
1135 This was not portable. float('0x3') now raises a ValueError.
1136
Barry Warsaw2a38a862005-12-18 01:27:35 +00001137- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001138 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001139 is now displayed in interactive prompt banner.
1140
Georg Brandlfa166682005-12-17 21:45:17 +00001141- Implementation of PEP 341 - Unification of try/except and try/finally.
1142 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001143 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001144
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001145- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1146 now encodes backslash correctly.
1147
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001148- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1149
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001150- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001151 and long longs.
1152
Neal Norwitz67715f02005-11-09 06:59:35 +00001153- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001154 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001155 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001156
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001157- Replaced most Unicode charmap codecs with new ones using the
1158 new Unicode translate string feature in the builtin charmap
1159 codec; the codecs were created from the mapping tables available
1160 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1161 encodings now include a mapping for the Apple logo)
1162
Tim Peterse3547fd2005-12-16 23:13:57 +00001163- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001164
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001165- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001166
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001167- A new AST parser implementation was completed. The abstract
1168 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001169 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001170
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001171- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001172 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1173
Neal Norwitz708e51a2005-10-03 04:48:15 +00001174- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1175
Neal Norwitz11bd1192005-10-03 00:54:56 +00001176- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1177 Provide a warning when a directory is passed on the command line.
1178
Neal Norwitz40d37812005-10-02 01:48:49 +00001179- Fix segfault with invalid coding.
1180
1181- SF bug #772896: unknown encoding results in MemoryError.
1182
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001183- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001184 supported a __len__() method which evaluated to False when the iterator
1185 was empty.
1186
Guido van Rossum630db602005-09-20 18:49:54 +00001187- On 64-bit platforms, when __len__() returns a value that cannot be
1188 represented as a C int, raise OverflowError.
1189
Skip Montanarof8948ca2005-09-19 03:54:46 +00001190- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001191 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001192
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001193- SF bug #893549: parsing keyword arguments was broken with a few format
1194 codes.
1195
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001196- Changes donated by Elemental Security to make it work on AIX 5.3
1197 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1198 bug #105470: test_pwd fails on 64bit system (Opteron).
1199
Guido van Rossum539c6622005-09-14 17:49:54 +00001200- Changes donated by Elemental Security to make it work on HP-UX 11 on
1201 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1202
Georg Brandl4550b8d2005-08-26 06:43:52 +00001203- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001204 (fixes bug #1119418).
1205
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001206- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1207
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001208- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1209 exceptions that cause a function to exit.
1210
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001211- The implementation of set() and frozenset() was revised to use its
1212 own internal data structure. Memory consumption is reduced by 1/3
1213 and there are modest speed-ups as well. The API is unchanged.
1214
Tim Petersde7990b2005-07-17 23:45:23 +00001215- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1216
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001217- SF bug #1229429: PyObject_CallMethod failed to decrement some
1218 reference counts in some error exit cases.
1219
Tim Petersecc6e6a2005-07-10 22:30:55 +00001220- SF bug #1185883: Python's small-object memory allocator took over
1221 a block managed by the platform C library whenever a realloc specified
1222 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001223 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001224 portable way to copy data from the C-managed block into Python's
1225 small-object space without risking a memory fault. Python's small-object
1226 realloc now leaves such blocks under the control of the platform C
1227 realloc.
1228
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001229- SF bug #1232517: An overflow error was not detected properly when
1230 attempting to convert a large float to an int in os.utime().
1231
Raymond Hettinger3296e692005-06-29 23:29:56 +00001232- SF bug #1224347: hex longs now print with lowercase letters just
1233 like their int counterparts.
1234
Michael W. Hudson188d4362005-06-20 16:52:57 +00001235- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1236 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1237 interpreter states; back out that fix and do a better job (see
1238 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1239 for a longer write-up of the problem).
1240
Michael W. Hudsondf888462005-06-03 14:41:55 +00001241- SF patch #1180995: marshal now uses a binary format by default when
1242 serializing floats.
1243
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001244- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1245 the routines that promise to produce IEEE 754 binary representations
1246 of floats now simply copy bytes around.
1247
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001248- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1249 278.
1250
Brett Cannonc3647ac2005-04-26 03:45:26 +00001251- patch #1109424: int, long, float, complex, and unicode now check for the
1252 proper magic slot for type conversions when subclassed. Previously the
1253 magic slot was ignored during conversion. Semantics now match the way
1254 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001255 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001256 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001257 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001258
Barry Warsawc8d907c2005-04-19 23:43:40 +00001259- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1260 NULL, now raise an AttributeError when attempting to set or delete the
1261 attribute. Previously a TypeError was raised, but this was inconsistent
1262 with the equivalent pure-Python implementation.
1263
Michael W. Hudson774479c2005-04-18 08:46:17 +00001264- It is now safe to call PyGILState_Release() before
1265 PyEval_InitThreads() (note that if there is reason to believe there
1266 are multiple threads around you still must call PyEval_InitThreads()
1267 before using the Python API; this fix is for extension modules that
1268 have no way of knowing if Python is multi-threaded yet).
1269
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001270- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1271 disabled caused a crash.
1272
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001273- Bug #1165306: instancemethod_new allowed the creation of a method
1274 with im_class == im_self == NULL, which caused a crash when called.
1275
Tim Petersecc6e6a2005-07-10 22:30:55 +00001276- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001277 fixes the crash seen in bug #1165761
1278
Raymond Hettinger96229b12005-03-11 06:49:40 +00001279- Added two new builtins, any() and all().
1280
Brett Cannon409d8f22005-03-05 06:47:57 +00001281- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001282 (e.g., ``class C(): pass`` is no longer a syntax error).
1283 Patch #1176012 added support to the 'parser' module and 'compiler' package
1284 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001285
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001286- Patch #1115086: Support PY_LONGLONG in structmember.
1287
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001288- Bug #1155938: new style classes did not check that __init__() was
1289 returning None.
1290
Tim Petersecc6e6a2005-07-10 22:30:55 +00001291- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001292 ('\') with a specific error message.
1293
Martin v. Löwisff232d72005-03-03 09:24:38 +00001294- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1295
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001296- Bug #1124295: the __name__ attribute of file objects was
1297 inadvertently made inaccessible in restricted mode.
1298
Tim Petersecc6e6a2005-07-10 22:30:55 +00001299- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001300 an ferror() call.
1301
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001302- min() and max() now support key= arguments with the same meaning as in
1303 list.sort().
1304
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001305- The peephole optimizer now performs simple constant folding in expressions:
1306 (2+3) --> (5).
1307
Raymond Hettingera422c342005-01-11 03:03:27 +00001308- set and frozenset objects can now be marshalled. SF #1098985.
1309
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001310- Bug #1077106: Poor argument checking could cause memory corruption
1311 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001312
Jeremy Hyltonab630502005-02-04 18:44:06 +00001313- The parser did not complain about future statements in illegal
1314 positions. It once again reports a syntax error if a future
1315 statement occurs after anything other than a doc string.
1316
Neil Schemenauercf52c072005-08-12 17:34:58 +00001317- Change the %s format specifier for str objects so that it returns a
1318 unicode instance if the argument is not an instance of basestring and
1319 calling __str__ on the argument returns a unicode instance.
1320
Tim Petersf4e69282006-02-27 17:15:31 +00001321- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1322 current thread state when the auto-GIL-state machinery knows about
1323 it (since the thread state is being deleted, continuing to remember it
1324 can't help, but can hurt if another thread happens to get created with
1325 the same thread id).
1326
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001327Extension Modules

1344
1345- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1346
1347- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001348 is deprecated. The undocumented re.engine variable no longer exists.
1349

1352
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001353- The unicodedata module was updated to the 4.1 version of the Unicode
1354 database. The 3.2 version is still available as unicodedata.db_3_2_0
1355 for applications that require this specific version (such as IDNA).
1356
Neal Norwitzb62c4332006-03-04 18:35:47 +00001357- The timing module is no longer built by default. It was deprecated
1358 in PEP 4 in Python 2.0 or earlier.
1359
Guido van Rossum1968ad32006-02-25 22:38:04 +00001360- Patch 1433928: Added a new type, defaultdict, to the collections module.

1362
Georg Brandldbd83392006-02-20 09:42:33 +00001363- Bug #854823: socketmodule now builds on Sun platforms even when

1378
Martin v. Löwis14694662006-02-03 12:54:16 +00001379- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1380 are reported, the limit on path name lengths is removed, and stat reports
1381 WindowsError now (instead of OSError).
1382

1458 the request code argument, which results in more C-like behaviour
1459 for large or negative values.
1460
Tim Petersecc6e6a2005-07-10 22:30:55 +00001461- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001501- the cPickle module no longer accepts the deprecated None option in the
1502 args tuple returned by __reduce__().
1503
Raymond Hettingerb2594052004-12-05 09:25:51 +00001504- itertools.islice() now accepts None for the start and step arguments.
1505 This allows islice() to work more readily with slices:

Tim Peters112aad32006-07-19 00:03:19 +00001516
Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001517- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1518 been renamed to have only a single underscore prefix. This was done to
1519 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001520
Nick Coghlan43832302006-04-23 17:04:07 +00001521- PEP 338: new module runpy defines a run_module function to support
1522 executing modules which provide access to source code or a code object
1523 via the PEP 302 import mechanisms.
1524
Anthony Baxter93f5b932006-04-03 08:05:07 +00001525- The email module's parsedate_tz function now sets the daylight savings
1526 flag to -1 (unknown) since it can't tell from the date whether it should

1533 in attribute values.
1534
Anthony Baxterc51ee692006-04-01 00:57:31 +00001535- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001536 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001537 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001538 module will not be built.
1539
Tim Petersc17976e2006-04-01 00:26:53 +00001540- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1541 aren't officially supported here, and trying to use them will probably
1542 raise an exception some day. But dicts have been allowed, and "mostly
1543 worked", so support for them won't go away without warning.
1544
Georg Brandl338ef7d2006-03-31 18:42:16 +00001545- Bug #1445068: getpass.getpass() can now be given an explicit stream
1546 argument to specify where to write the prompt.
1547
Georg Brandl22ec80b2006-03-31 18:25:44 +00001548- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1557 to make it easier to monitor when daemon threads have completed
1558 processing all enqueued tasks. Patch #1455676.
1559
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001560- popen2.Popen objects now preserve the command in a .cmd attribute.

1563
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001564- email 4.0 package now integrated. This is largely the same as the email 3.0
1565 package that was included in Python 2.3, except that PEP 8 module names are
1566 now used (e.g. mail.message instead of email.Message). The MIME classes
1567 have been moved to a subpackage (e.g. email.mime.text instead of
1568 email.MIMEText). The old names are still supported for now. Several
1569 deprecated Message methods have been removed and lots of bugs have been
1570 fixed. More details can be found in the email package documentation.
1571
Walter Dörwald40108c92006-03-27 08:15:44 +00001572- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1573 (a subclass of tuple) that provides incremental decoders and encoders
1574 (a way to use stateful codecs without the stream API). Python functions
1575 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1576 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1577 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001578
Walter Dörwald067db482006-03-15 22:17:27 +00001579- Patch #1359365: Calling next() on a closed StringIO.String object raises
1580 a ValueError instead of a StopIteration now (like file and cString.String do).
1581 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1582 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001583
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001584- A regrtest option -w was added to re-run failed tests in verbose mode.

1596 and helpful context managers nested() and closing().
1597

Martin v. Löwis3e865952006-01-24 15:51:21 +00001632 specifications, raises IOErrors when proxies for unsupported protocols
1633 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00001656 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1657 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1658 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1659 Ronald L. Rivest offered this advice for Python:
1660
1661 "The consensus of researchers in this area (at least as
1662 expressed at the NIST Hash Function Workshop 10/31/05),
1663 is that SHA-256 is a good choice for the time being, but
1664 that research should continue, and other alternatives may
1665 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001666
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001667- Added a subset of Fredrik Lundh's ElementTree package. Available

1744 to W3C name (404 -> 'Not Found'). RFE #1216944.
1745
Georg Brandl9e43acf2005-07-04 17:16:07 +00001746- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1747 as this can cause problems with apps closing all file descriptors.
1748
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001749- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001750 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00001751

1753
Georg Brandlfbff1bc2005-06-26 21:36:25 +00001754- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
1755 error messages.
1756
Georg Brandl379f99d2005-06-26 21:09:38 +00001757- Bug #1108948: Cookie.py produced invalid JavaScript code.

Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001759- The tokenize module now detects and reports indentation errors.
1760 Bug #1224621.
1761
Raymond Hettinger68c04532005-06-10 11:05:19 +00001762- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001763 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001764 the generate_tokens() function now accepts a callable argument that
1765 terminates by raising StopIteration.
1766
Georg Brandl9166e1a2005-06-04 09:20:03 +00001767- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1768
Georg Brandl268e61c2005-06-03 14:28:50 +00001769- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1770 component of the path.
1771
Skip Montanaro174dd222005-05-14 20:54:16 +00001772- Patch #1120353: The xmlrpclib module provides better, more transparent,
1773 support for datetime.{datetime,date,time} objects. With use_datetime set
1774 to True, applications shouldn't have to fiddle with the DateTime wrapper
1775 class at all.
1776
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001777- distutils.commands.upload was added to support uploading distribution
1778 files to PyPI.
1779
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001780- distutils.commands.register now encodes the data as UTF-8 before posting
1781 them to PyPI.
1782
Raymond Hettinger267b8682005-03-27 10:47:39 +00001783- decimal operator and comparison methods now return NotImplemented
1784 instead of raising a TypeError when interacting with other types. This
1785 allows other classes to implement __radd__ style methods and have them
1786 work as expected.
1787
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001788- Bug #1163325: Decimal infinities failed to hash. Attempting to
1789 hash a NaN raised an InvalidOperation instead of a TypeError.
1790
Tim Petersecc6e6a2005-07-10 22:30:55 +00001791- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1825
Guido van Rossumd0641422005-02-03 15:01:24 +00001826- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1827 disables recursive traversal through instance attributes, which can
1828 be exploited in various ways.
1829
Tim Peterse3547fd2005-12-16 23:13:57 +00001830- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001831 flags on the HTTP listening socket.
1832
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001833- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1834 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1835
Fred Drakefbdeaad2006-07-29 16:56:15 +00001836- Patches #893642, #1039083: add allow_none, encoding arguments to
1837 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001838
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001839- Bug #1110478: Revert os.environ.update to do putenv again.

Thomas Hellerd6c6e222005-01-20 19:20:16 +00001841- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1842
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001843- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1844
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001845- Enhancements to the csv module:
1846
1847 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001848 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001849 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001850 + Dialect parameter parsing has been re-implemented to improve error
1851 reporting.
1852 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1853 dictates.
1854 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001855 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001856 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001857 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1858 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001859 + reader now allows \r characters to be quoted (previously it only allowed
1860 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001861 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001862 + Dialect classes passed to the module are no longer instantiated by
1863 the module before being parsed (the former validation scheme required
1864 this, but the mechanism was unreliable).
1865 + The dialect registry now contains instances of the internal
1866 C-coded dialect type, rather than references to python objects.
1867 + the internal c-coded dialect type is now immutable.
1868 + register_dialect now accepts the same keyword dialect specifications
1869 as the reader and writer, allowing the user to register dialects
1870 without first creating a dialect class.
1871 + a configurable limit to the size of parsed fields has been added -
1872 previously, an unmatched quote character could result in the entire
1873 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001874 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001875 the parser field size limit (returning the former limit). The initial
1876 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001877 + A line_num attribute has been added to the reader object, which tracks
1878 the number of lines read from the source iterator. This is not
1879 the same as the number of records returned, as records can span
1880 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001881 + reader and writer objects were not being registered with the cyclic-GC.
1882 This has been fixed.
1883
Brett Cannone6539c42005-01-08 02:43:53 +00001884- _DummyThread objects in the threading module now delete self.__block that is
1885 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1886 lock primitives tend to be limited in number and thus should not be wasted on
1887 a _DummyThread object. Fixes bug #1089632.
1888
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001889- The imghdr module now detects Exif files.
1890
Raymond Hettinger6065d322004-12-20 23:51:53 +00001891- StringIO.truncate() now correctly adjusts the size attribute.
1892 (Bug #951915).
1893
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001894- locale.py now uses an updated locale alias table (built using
1895 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1896 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001897 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001898
Raymond Hettinger3557f422004-12-07 12:02:02 +00001899- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1900
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001901- the pickle module no longer accepts the deprecated None option in the
1902 args tuple returned by __reduce__().
1903
Brett Cannon84667c02004-12-07 03:25:18 +00001904- optparse now optionally imports gettext. This allows its use in setup.py.
1905
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001906- the pickle module no longer uses the deprecated bin parameter.
1907
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001908- the shelve module no longer uses the deprecated binary parameter.
1909
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001910- the pstats module no longer uses the deprecated ignore() method.
1911
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001912- the filecmp module no longer uses the deprecated use_statcache argument.
1913
Raymond Hettinger664347b2004-12-04 21:21:53 +00001914- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1915 extended or overridden by subclasses. Formerly, the subclassed method would
1916 be ignored by the rest of the module. (Bug #1078905).
1917
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001918- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001919 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001920
Walter Dörwald36733692004-12-22 12:50:50 +00001921- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1922 once when a size argument is given. This prevents a buffer overflow in the
1923 tokenizer with very long source lines.
1924
Barry Warsaw538561e2006-01-01 21:48:54 +00001925- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1926 immediately after creating the object, without any intervening
1927 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001928
Skip Montanaro05885812005-01-16 20:48:27 +00001929- The reconvert.quote function can now emit triple-quoted strings. The
1930 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001931
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001932- ``UserString.MutableString`` now supports negative indices in
1933 ``__setitem__`` and ``__delitem__``
1934
Greg Ward40407942005-03-05 02:53:17 +00001935- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1936 correctly.
1937
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001938- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1939 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1940 character even if the user has passed a size parameter to get a proper
1941 line ending. Remove the special handling of a "\r\n" that has been split
1942 between two lines.
1943
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001944- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1945 about illegal code points. The codec now supports PEP 293 style error
1946 handlers.
1947
Walter Dörwald78a78b02005-09-01 12:04:29 +00001948- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001949 from the input stream, so that the output is a byte string in the correct
1950 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001951
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001952- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1953 considering it exactly like a '*'.
1954
Walter Dörwald007f8df2005-10-09 19:42:27 +00001955- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1956 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001957
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001958- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1959
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001960- Patch #1413711: Certain patterns of differences were making difflib
1961 touch the recursion limit.
1962
Walter Dörwald58917a62006-03-31 15:26:22 +00001963- Bug #947906: An object oriented interface has been added to the calendar
1964 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001965 called as a script (e.g. via ``python -mcalendar``). Localized month and
1966 weekday names can be ouput (even if an exotic encoding is used) using
1967 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001968

1992 vulnerability in zlib 1.2.1 and 1.2.2.
1993
Brett Cannon08cd5982005-04-24 22:26:38 +00001994- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1995 flags that change binary compatibility. Changes were also made to
1996 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001997 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001998

Martin v. Löwise2713be2005-03-08 15:03:08 +00002003- Bug #1158607: Build with --disable-unicode again.
2004
Brett Cannon46d96232005-02-16 00:07:19 +00002005- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2006 defined. Discovered as a result of not being able to build on OS X.
2007
Brett Cannon516592f2004-12-07 00:42:59 +00002008- setup.py now uses the directories specified in LDFLAGS using the -L option
2009 and in CPPFLAGS using the -I option for adding library and include
2010 directories, respectively, for compiling extension modules against. This has
2011 led to the core being compiled using the values in CPPFLAGS. It also removes
2012 the need for the special-casing of both DarwinPorts and Fink for darwin since
2013 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2014 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2015 Fink, ``-I/opt/local/include`` for DarwinPorts).
2016
Brett Cannon43802422005-02-10 20:48:03 +00002017- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2018 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2019 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2020 Closes bug #1096244. Thanks Gregory Bond.

2023-----
2024
Tim Petersc9d78aa2006-03-26 23:27:58 +00002025- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2026 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2027 is obtained via the ``PyObject_`` family, it must be released via the
2028 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2029 always been officially true, but when Python's small-object allocator was
2030 introduced, an attempt was made to cater to a few extension modules
2031 discovered at the time that obtained memory via ``PyObject_New`` but
2032 released it via ``PyMem_DEL``. It's years later, and if such code still
2033 exists it will fail now (probably with segfaults, but calling wrong
2034 low-level memory management functions can yield many symptoms).
2035
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002036- Added a C API for set and frozenset objects.
2037
Raymond Hettinger66517482004-12-03 11:45:13 +00002038- Removed PyRange_New().
2039
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002040- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2041 mapping argument now. This string is used as a mapping table. Byte values
2042 greater than the length of the string and 0xFFFE are treated as undefined
2043 mappings.

Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002051- Patch #1276356: New resource "urlfetch" is implemented. This enables
2052 even impatient people to run tests that require remote files.
