Marc-André Lemburg040f76b2006-08-14 10:55:19 +000025- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +000026 compared equal or unequal to a string and a UnicodeDecodeError
27 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +000028
Marc-André Lemburg040f76b2006-08-14 10:55:19 +000029 Instead, the equal (==) and unequal (!=) comparison operators will
30 now issue a UnicodeWarning and interpret the two objects as
31 unequal. The UnicodeWarning can be filtered as desired using
32 the warning framework, e.g. silenced completely, turned into an
33 exception, logged, etc.
34
35 Note that compare operators other than equal and unequal will still
36 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +000037
Marc-André Lemburg757ea272006-08-14 11:44:34 +000038- Fix segfault when doing string formatting on subclasses of long.
39
40- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
41 with new-style classes.
42
43- Fix bug related to __len__ functions returning negative values with
44 classic classes.
45
46- Patch #1538606, Fix __index__() clipping. There were some problems
47 discovered with the API and how integers that didn't fit into Py_ssize_t
48 were handled. This patch attempts to provide enough alternatives
49 to effectively use __index__.
50
Martin v. Löwisab2f8f72006-08-09 07:57:39 +000051- Bug #1536021: __hash__ may now return long int; the final hash
52 value is obtained by invoking hash on the long int.
53
Thomas Hellerab1049c2006-08-08 17:37:00 +000054- Bug #1536786: buffer comparison could emit a RuntimeWarning.
55
Georg Brandl7e3ba2a2006-08-06 08:23:54 +000056- Bug #1535165: fixed a segfault in input() and raw_input() when
57 sys.stdin is closed.
58
Thomas Heller74d36f02006-08-04 18:17:40 +000059- On Windows, the PyErr_Warn function is now exported from
60 the Python dll again.
61
Neal Norwitz4ffedad2006-08-04 04:58:47 +000062- Bug #1191458: tracing over for loops now produces a line event
63 on each iteration. Fixing this problem required changing the .pyc
64 magic number. This means that .pyc files generated before 2.5c1
65 will be regenerated.
66
Neal Norwitz0cbd8052006-08-04 05:09:28 +000067- Bug #1333982: string/number constants were inappropriately stored
68 in the byte code and co_consts even if they were not used, ie
69 immediately popped off the stack.
70
Georg Brandle9462c72006-08-04 18:03:37 +000071- Fixed a reference-counting problem in property().

74Library
75-------
76
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +000077- Fix a bug in the ``compiler`` package that caused invalid code to be
78 generated for generator expressions.
79
Marc-André Lemburg574cfea2006-08-16 16:11:01 +000080- The distutils version has been changed to 2.5.0. The change to
81 keep it programmatically in sync with the Python version running
82 the code (introduced in 2.5b3) has been reverted. It will continue
83 to be maintained manually as static string literal.
84
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +000085- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +000086 and this cannot be converted to the required C type, an exception is
87 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +000088 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +000089
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +000090- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +000091 an exception.
92
Anthony Baxter58179592006-08-16 13:08:25 +000093- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +000094 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +000095 workarounds for clocks with low resolution, to stop the code yielding
96 duplicate UUIDs.
97
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +000098- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
99 before raising SystemExit, allowing IDLE to honor quit() and exit().
100
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000101- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
102
Georg Brandl7a1af772006-08-14 21:55:28 +0000103- Patch #1536071: trace.py should now find the full module name of a
104 file correctly even on Windows.
105
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000106- logging's atexit hook now runs even if the rest of the module has
107 already been cleaned up.
108
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000109- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000110
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000111- Bug #1531405, format_exception no longer raises an exception if
112 str(exception) raised an exception.
113
Neil Schemenauer06ded092006-08-04 16:20:30 +0000114- Fix a bug in the ``compiler`` package that caused invalid code to be
115 generated for nested functions.
116
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000117

122
Georg Brandl3335a7a2006-08-14 21:42:55 +0000123- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
124 raises the correct exceptions.
125
Thomas Heller1ce433e2006-08-14 16:20:04 +0000126- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
127 '-no-stack-protector' compiler flag for OpenBSD has been removed.
128
Thomas Heller86720042006-08-14 11:17:48 +0000129- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
130 uses the _as_parameter_ attribute when objects are passed to foreign
131 function calls. The ctypes version number was changed to 1.0.1.
132
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000133- Bug #1530559, struct.pack raises TypeError where it used to convert.
134 Passing float arguments to struct.pack when integers are expected
135 now triggers a DeprecationWarning.
136
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000137

159-----
160
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000161- Bug #1535502, build _hashlib on Windows, and use masm assembler
162 code in OpenSSL.
163
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000164- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Fred Drake53912162006-07-29 13:22:49 +0000184What's New in Python 2.5 beta 3?
185================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000186
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000187*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000188
189Core and builtins
190-----------------
191
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000192- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000193 returned a long (see PEP 353).
194
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000195- Bug #1515471: string.replace() accepts character buffers again.
196
Neal Norwitz07aadb12006-07-30 06:55:48 +0000197- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
198 This provides the proper warning for struct.pack().
199 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
200
Neal Norwitz0d62a062006-07-30 06:53:31 +0000201- Patch #1531113: Fix augmented assignment with yield expressions.
202 Also fix a SystemError when trying to assign to yield expressions.
203
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000204- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
205 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
206 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
207 excessive filesystem operations during imports.
208
Tim Petersbc24eee2006-07-27 01:14:53 +0000209- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
210 operations on signed longs that are formally undefined by C.
211 Unfortunately, at least one compiler now cares about that, so complicated
212 the code to make that compiler happy again.
213
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000214- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
215
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000216- Patch #1232023: Stop including current directory in search
217 path on Windows.
218
Neal Norwitze1fdb322006-07-21 05:32:28 +0000219- Fix some potential crashes found with failmalloc.
220
Neal Norwitze7563102006-07-17 01:00:16 +0000221- Fix warnings reported by Klocwork's static analysis tool.
222
Neal Norwitz84be93b2006-07-16 01:50:38 +0000223- Bug #1512814, Fix incorrect lineno's when code within a function
224 had more than 255 blank lines.
225
Georg Brandl9dceedb2006-07-12 15:31:17 +0000226- Patch #1521179: Python now accepts the standard options ``--help`` and
227 ``--version`` as well as ``/?`` on Windows.
228
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000229- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000230 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000231 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000232
Tim Peters112aad32006-07-19 00:03:19 +0000233- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000234 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000235 new ``sys._current_frames()`` returns a dictionary with one entry,
236 mapping the faux "thread id" 0 to the current frame.
237
Ronald Oussoren3075e162006-07-25 20:28:55 +0000238- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000239

Neal Norwitza1f10902006-07-12 07:28:29 +0000241Library
242-------
243
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000244- Correction of patch #1455898: In the mbcs decoder, set final=False
245 for stream decoder, but final=True for the decode function.
246
Georg Brandl07fec3a2006-08-01 18:49:24 +0000247- os.urandom no longer masks unrelated exceptions like SystemExit or
248 KeyboardInterrupt.
249
Tim Peters4643c2f2006-08-10 22:45:34 +0000250- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000251 shutil.copytree on Windows
252
Georg Brandle34ac7c2006-07-30 11:07:23 +0000253- Bug #1002398: The documentation for os.path.sameopenfile now correctly
254 refers to file descriptors, not file objects.
255
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000256- The renaming of the xml package to xmlcore, and the import hackery done
257 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000258 #1513611, and probably others.
259
Georg Brandledd9b0d2006-07-29 09:33:26 +0000260- Bug #1441397: The compiler module now recognizes module and function
261 docstrings correctly as it did in Python 2.4.
262
Tim Peters6f681472006-07-27 23:44:37 +0000263- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
264 lost that tests are sorted by name before being run. This rarely
265 matters for well-written tests, but can create baffling symptoms if
266 side effects from one test to the next affect outcomes. ``DocTestFinder``
267 has been changed to sort the list of tests it returns.
268
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000269- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000270 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000271
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000272- Bug #978833: Really close underlying socket in _socketobject.close.
273
Georg Brandl0619a322006-07-26 07:40:17 +0000274- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
275 with title().
276
Georg Brandlcf0c1722006-07-26 07:23:32 +0000277- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
278 to recursive calls and call it with the failing package name.
279
Martin v. Löwis0b483032006-07-25 09:53:12 +0000280- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
281
Georg Brandlc13c34c2006-07-24 14:09:56 +0000282- Patch #1515343: Fix printing of deprecated string exceptions with a
283 value in the traceback module.
284
Greg Ward48fae7a2006-07-23 16:05:51 +0000285- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
286
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000287- Patch #1524429: Use repr() instead of backticks in Tkinter again.
288
Brett Cannoncaebe222006-07-18 04:41:36 +0000289- Bug #1520914: Change time.strftime() to accept a zero for any position in its
290 argument tuple. For arguments where zero is illegal, the value is forced to
291 the minimum value that is correct. This is to support an undocumented but
292 common way people used to fill in inconsequential information in the time
293 tuple pre-2.4.
294
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000295- Patch #1220874: Update the binhex module for Mach-O.
296
Barry Warsawb110bad2006-07-21 14:51:07 +0000297- The email package has improved RFC 2231 support, specifically for
298 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
299 (name*0=<blah>) parameter continuations. This may change the types of
300 values returned from email.message.Message.get_param() and friends.
301 Specifically in some cases where non-encoded continuations were used,
302 get_param() used to return a 3-tuple of (None, None, string) whereas now it
303 will just return the string (since non-encoded continuations don't have
304 charset and language parts).
305
306 Also, whereas % values were decoded in all parameter continuations, they are
307 now only decoded in encoded parameter parts.
308
Ronald Oussoren3075e162006-07-25 20:28:55 +0000309- Bug #1517990: IDLE keybindings on MacOS X now work correctly
310
311- Bug #1517996: IDLE now longer shows the default Tk menu when a
312 path browser, class browser or debugger is the frontmost window on MacOS X
313
Barry Warsaw00decd72006-07-27 23:43:15 +0000314- Patch #1520294: Support for getset and member descriptors in types.py,
315 inspect.py, and pydoc.py. Specifically, this allows for querying the type
316 of an object against these built-in types and more importantly, for getting
317 their docstrings printed in the interactive interpreter's help() function.

321-----------------
322
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000323- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
324 a socket operation on a socket with a timeout, the exception will be
325 caught correctly. Previously, the exception was not caught.
326
Thomas Heller1393d6a2006-07-28 21:43:20 +0000327- Patch #1529514: The _ctypes extension is now compiled on more
328 openbsd target platforms.
329
Tim Peters9cab5932006-07-28 00:30:00 +0000330- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
331 a memory leak, affecting pickles and deep copies.
332
Tim Petersbc24eee2006-07-27 01:14:53 +0000333- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

337
Thomas Hellerce049a02006-07-14 17:51:14 +0000338- Patch #1521817: Index range checking on ctypes arrays containing
339 exactly one element enabled again. This allows iterating over these
340 arrays, without the need to check the array size before.
341
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000342- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000343 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000344 /dev/null in certain cases; this is now fixed.
345
Thomas Heller47d7a062006-07-12 08:43:47 +0000346- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
347 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000348
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000349- Because of a misspelled preprocessor symbol, ctypes was always
350 compiled without thread support; this is now fixed.
351
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000352- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
353 methods now allow their database parameter to be None as the
354 sleepycat API allows.
355
Matt Flemingec926502006-07-28 11:27:27 +0000356- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
357 bluetooth API compared with Linux and FreeBSD.
358
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000359Tests
360-----
361
362- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
363 how long the test file should take to play. Now accepts taking 2.93 secs
364 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
365
Georg Brandl4793aa32006-07-28 18:31:39 +0000366- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
367 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
368 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000375Mac
376---
377
378- PythonLauncher now works correctly when the path to the script contains
379 characters that are treated specially by the shell (such as quotes).
380
381- Bug #1527397: PythonLauncher now launches scripts with the working directory
382 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000383 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000384 expect.

392Core and builtins
393-----------------
394
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000395- Bug #1441486: The literal representation of -(sys.maxint - 1)
396 again evaluates to a int object, not a long.
397
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000398- Bug #1501934: The scope of global variables that are locally assigned
399 using augmented assignment is now correctly determined.
400
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000401- Bug #927248: Recursive method-wrapper objects can now safely
402 be released.
403
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000404- Bug #1417699: Reject locale-specific decimal point in float()
405 and atof().
406
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000407- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
408 omit a default "error" argument for NULL pointer. This allows
409 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000410
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000411- Bug #1519018: 'as' is now validated properly in import statements.
412
Neal Norwitz28746ab2006-07-09 22:14:42 +0000413- On 64 bit systems, int literals that use less than 64 bits are
414 now ints rather than longs.
415
Neal Norwitzed657552006-07-10 00:04:44 +0000416- Bug #1512814, Fix incorrect lineno's when code at module scope
417 started after line 256.
418
Tim Peters32a83612006-07-10 21:08:24 +0000419- New function ``sys._current_frames()`` returns a dict mapping thread
420 id to topmost thread stack frame. This is for expert use, and is
421 especially useful for debugging application deadlocks. The functionality
422 was previously available in Fazal Majid's ``threadframe`` extension
423 module, but it wasn't possible to do this in a wholly threadsafe way from
424 an extension.

441
Thomas Woutersadd19112006-07-05 11:03:49 +0000442- string.Template() now correctly handles tuple-values. Previously,
443 multi-value tuples would raise an exception and single-value tuples would
444 be treated as the value they contain, instead.
445
Martin v. Löwisede77f52006-07-03 13:01:35 +0000446- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
447 even if some data are received.

453 degrees and radians.
454
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000455- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000456 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000457
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000458- Bug #1514703: Only setup canvas window in turtle when the canvas
459 is created.
460
Martin v. Löwis7596e832006-07-01 15:33:37 +0000461- Bug #1513223: .close() of a _socketobj now releases the underlying
462 socket again, which then gets closed as it becomes unreferenced.
463
Fred Drake10497c82006-06-29 02:57:48 +0000464- Bug #1504333: Make sgmllib support angle brackets in quoted
465 attribute values.
466
467- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
468 sgmllib ('[' and ']' were not accepted).
469
Georg Brandl1be63af2006-06-28 20:23:25 +0000470- Fix a bug in the turtle module's end_fill function.
471
Brett Cannon53ab5b72006-06-22 16:49:14 +0000472- Bug #1510580: The 'warnings' module improperly required that a Warning
473 category be either a types.ClassType and a subclass of Warning. The proper
474 check is just that it is a subclass with Warning as the documentation states.
475
Georg Brandlad29e632006-06-21 17:45:17 +0000476- The compiler module now correctly compiles the new try-except-finally
477 statement (bug #1509132).
478
Neal Norwitz60373cd2006-06-22 06:30:50 +0000479- The wsgiref package is now installed properly on Unix.
480
Vinay Sajip28e57612006-07-01 10:45:20 +0000481- A bug was fixed in logging.config.fileConfig() which caused a crash on
482 shutdown when fileConfig() was called multiple times.
483
Gerhard Häring762fbd32006-07-02 17:48:30 +0000484- The sqlite3 module did cut off data from the SQLite database at the first
485 null character before sending it to a custom converter. This has been fixed
486 now.
487

489-----------------
490
Tim Peters112aad32006-07-19 00:03:19 +0000491- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
492 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
493 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000494
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000495- Assigning None to pointer type fields in ctypes structures possible
496 overwrote the wrong fields, this is fixed now.
497
498- Fixed a segfault in _ctypes when ctypes.wintypes were imported
499 on non-Windows platforms.
500
501- Bug #1518190: The ctypes.c_void_p constructor now accepts any
502 integer or long, without range checking.
503
504- Patch #1517790: It is now possible to use custom objects in the ctypes
505 foreign function argtypes sequence as long as they provide a from_param
506 method, no longer is it required that the object is a ctypes type.
507
508- The '_ctypes' extension module now works when Python is configured
509 with the --without-threads option.
510
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000511- Bug #1513646: os.access on Windows now correctly determines write
512 access, again.
513
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000514- Bug #1512695: cPickle.loads could crash if it was interrupted with
515 a KeyboardInterrupt.
516
Neal Norwitza12aa882006-07-06 06:45:08 +0000517- Bug #1296433: parsing XML with a non-default encoding and
518 a CharacterDataHandler could crash the interpreter in pyexpat.
519
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000520- Patch #1516912: improve Modules support for OpenVMS.

523-----
524
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000525- Automate Windows build process for the Win64 SSL module.
526
Tim Peters32a83612006-07-10 21:08:24 +0000527- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000528 Previously, the slight difference could cause compilation errors of the
529 'zlib' module on systems with more than one version of zlib.
530
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000531- The MSI compileall step was fixed to also support a TARGETDIR
532 with spaces in it.
533

535 of Tcl/Tk.
536
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000537- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000538 trying to be installed even though it's empty.

562Core and builtins
563-----------------
564
Georg Brandla56b9152006-06-19 06:35:54 +0000565- Patch #1507676: Error messages returned by invalid abstract object operations
566 (such as iterating over an integer) have been improved and now include the
567 type of the offending object to help with debugging.
568
Brett Cannonea3912b2006-06-13 21:46:41 +0000569- Bug #992017: A classic class that defined a __coerce__() method that returned
570 its arguments swapped would infinitely recurse and segfault the interpreter.
571
Neal Norwitz909eb122006-06-12 02:13:21 +0000572- Fix the socket tests so they can be run concurrently.
573
Neal Norwitzb9845e72006-06-12 02:11:18 +0000574- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000575 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000576
Brett Cannon22565aa2006-06-09 22:31:23 +0000577- Bug #532646: object.__call__() will continue looking for the __call__
578 attribute on objects until one without one is found. This leads to recursion
579 when you take a class and set its __call__ attribute to an instance of the
580 class. Originally fixed for classic classes, but this fix is for new-style.
581 Removes the infinite_rec_3 crasher.
582
Georg Brandl24250812006-06-09 18:45:48 +0000583- The string and unicode methods startswith() and endswith() now accept
584 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
585
Brett Cannonde3b0522006-06-08 17:00:45 +0000586- Buffer objects, at the C level, never used the char buffer
587 implementation even when the char buffer for the wrapped object was
588 explicitly requested (originally returned the read or write buffer).
589 Now a TypeError is raised if the char buffer is not present but is
590 requested.
591
Georg Brandlddbaa662006-06-04 21:56:52 +0000592- Patch #1346214: Statements like "if 0: suite" are now again optimized
593 away like they were in Python 2.4.
594
Georg Brandlb7c8f542006-05-27 12:30:25 +0000595- Builtin exceptions are now full-blown new-style classes instead of
596 instances pretending to be classes, which speeds up exception handling
597 by about 80% in comparison to 2.5a2.
598
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000599- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
600 Unicode 4.1.
601
Georg Brandlf4ef1162006-05-26 18:03:31 +0000602- Patch #921466: sys.path_importer_cache is now used to cache valid and
603 invalid file paths for the built-in import machinery which leads to
604 fewer open calls on startup.
605
Tim Peters696cf432006-05-24 21:10:40 +0000606- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
607 of-2 bases. The largest speedup is for inputs with about 1000 decimal
608 digits. Conversion from non-power-of-2 bases remains quadratic-time in
609 the number of input digits (it was and remains linear-time for bases
610 2, 4, 8, 16 and 32).
611
Tim Petersb713ec22006-05-23 18:45:30 +0000612- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
613 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
614 an integer close to ``sys.maxint``. This was repaired by patch
615 #1335972, which also gives a nice speedup.
616
Richard Jonescebbefc2006-05-23 18:28:17 +0000617- Patch #1337051: reduced size of frame objects.
618
619- PyErr_NewException now accepts a tuple of base classes as its
620 "base" parameter.
621
Richard Jones7c88dcc2006-05-23 10:37:38 +0000622- Patch #876206: function call speedup by retaining allocated frame
623 objects.
624
Georg Brandl7b90e162006-05-18 07:01:27 +0000625- Bug #1462152: file() now checks more thoroughly for invalid mode
626 strings and removes a possible "U" before passing the mode to the
627 C library function.
628
Neal Norwitz1004a532006-05-15 07:17:23 +0000629- Patch #1488312, Fix memory alignment problem on SPARC in unicode
630
Neal Norwitz373f0a72006-05-15 07:04:36 +0000631- Bug #1487966: Fix SystemError with conditional expression in assignment
632
Martin v. Löwis879768d2006-05-11 13:28:43 +0000633- WindowsError now has two error code attributes: errno, which carries
634 the error values from errno.h, and winerror, which carries the error
635 values from winerror.h. Previous versions put the winerror.h values
636 (from GetLastError()) into the errno attribute.
637
Martin v. Löwis77736712006-05-04 05:51:03 +0000638- Patch #1475845: Raise IndentationError for unexpected indent.
639
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000640- Patch #1479181: split open() and file() from being aliases for each other.
641
Tim Peters44bd9862006-06-01 13:49:23 +0000642- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
643 methods were always silently ignored by dictionaries when comparing keys.
644 They are now passed through (except when using the C API function
645 ``PyDict_GetItem()``, whose semantics did not change).
646
647- Bug #1456209: In some obscure cases it was possible for a class with a
648 custom ``__eq__()`` method to confuse dict internals when class instances
649 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
650 No, you don't have any code that did this ;-)

656
657- Patch #1462338: Upgrade pyexpat to expat 2.0.0
658
Brett Cannon6ee7d012006-06-08 16:23:04 +0000659- Change binascii.hexlify to accept a read-only buffer instead of only a char
660 buffer and actually follow its documentation.
661
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000662- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
663
Nick Coghlanc649ec52006-05-29 12:43:05 +0000664- Patch #1478788 (modified version): The functional extension module has
665 been renamed to _functools and a functools Python wrapper module added.
666 This provides a home for additional function related utilities that are
667 not specifically about functional programming. See PEP 309.
668
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000669- Patch #1493701: performance enhancements for struct module.
670
Georg Brandl378d5922006-05-17 14:26:50 +0000671- Patch #1490224: time.altzone is now set correctly on Cygwin.
672
Georg Brandl8d3342b2006-05-16 07:38:27 +0000673- Patch #1435422: zlib's compress and decompress objects now have a
674 copy() method.
675
Andrew MacIntyre92913322006-06-13 15:04:24 +0000676- Patch #1454481: thread stack size is now tunable at runtime for thread
677 enabled builds on Windows and systems with Posix threads support.
678
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000679- On Win32, os.listdir now supports arbitrarily-long Unicode path names
680 (up to the system limit of 32K characters).
681
682- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
683 As a result, these functions now raise WindowsError instead of OSError.
684
Tim Peters7a822da2006-05-25 21:50:17 +0000685- ``time.clock()`` on Win64 should use the high-performance Windows
686 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
687 Windows platforms).
688
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000689- Calling Tk_Init twice is refused if the first call failed as that
690 may deadlock.
691
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000692- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
693 accept it without potentially using an uninitialized pointer.
694
695- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
696 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
697 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000698
Gregory P. Smith372b5832006-06-05 18:48:21 +0000699- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000700 [pybsddb project SF patch number 1466734]
701
Gregory P. Smith372b5832006-06-05 18:48:21 +0000702- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
703 parameter is supplied. [SF pybsddb bug #1477863]
704
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000705- bsddb: the __len__ method of a DB object has been fixed to return correct
706 results. It could previously incorrectly return 0 in some cases.
707 Fixes SF bug 1493322 (pybsddb bug 1184012).
708
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000709- bsddb: the bsddb.dbtables Modify method now raises the proper error and
710 aborts the db transaction safely when a modifier callback fails.
711 Fixes SF python patch/bug #1408584.
712
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000713- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000714 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000715 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
716 database calls that would previously deadlock. [SF python bug #775414]
717
Vinay Sajip28e57612006-07-01 10:45:20 +0000718- Patch #1446489: add support for the ZIP64 extensions to zipfile.

738
Georg Brandl83cc0d02006-06-14 08:50:03 +0000739- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
740 mime.types file for determining MIME types.
741
Georg Brandl2605ca82006-06-14 06:08:31 +0000742- Bug #1339007: Shelf objects now don't raise an exception in their
743 __del__ method when initialization failed.
744
Martin v. Löwisd8251432006-06-14 05:21:04 +0000745- Patch #1455898: The MBCS codec now supports the incremental mode for
746 double-byte encodings.
747
Tim Peters43898b42006-06-14 04:09:25 +0000748- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
749 guarantee that adjacent triples in the return list always describe
750 non-adjacent blocks. Previously, a pair of matching blocks could end
751 up being described by multiple adjacent triples that formed a partition
752 of the matching pair.
753
Greg Ward0e0c9f42006-06-11 16:24:11 +0000754- Bug #1498146: fix optparse to handle Unicode strings in option help,
755 description, and epilog.
756
Greg Wardd1c797e2006-06-11 14:42:41 +0000757- Bug #1366250: minor optparse documentation error.
758
Greg Ward7f547402006-06-11 00:40:49 +0000759- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
760 clarify docs.
761
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000762- The wsgiref package has been added to the standard library.
763
Nick Coghlan676725d2006-06-08 13:54:49 +0000764- The functions update_wrapper() and wraps() have been added to the functools
765 module. These make it easier to copy relevant metadata from the original
766 function when writing wrapper functions.
767
Tim Petersd6a9eef2006-06-05 01:48:21 +0000768- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
769 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000770
Martin v. Löwis3f767792006-06-04 19:36:28 +0000771- Patch #1359618: Speed up charmap encoder by using a trie structure
772 for lookup.
773
Tim Petersd609b1a2006-06-02 23:22:51 +0000774- The functions in the ``pprint`` module now sort dictionaries by key
775 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
776 if and only if its display required more than one line, although that
777 wasn't documented. The new behavior increases predictability; e.g.,
778 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
779
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000780- Patch #1497027: try HTTP digest auth before basic auth in urllib2

782
Georg Brandl2b330372006-05-28 20:23:12 +0000783- Patch #1496206: improve urllib2 handling of passwords with respect to
784 default HTTP and HTTPS ports.
785
George Yoshidaf3c65de2006-05-28 16:39:09 +0000786- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
787
Bob Ippolito7298f272006-05-23 18:43:47 +0000788- Patch #1281707: speed up gzip.readline.
789
Georg Brandlb89316f2006-05-17 15:51:16 +0000790- Patch #1180296: Two new functions were added to the locale module:
791 format_string() to get the effect of "format % items" but locale-aware,
792 and currency() to format a monetary number with currency sign.
793
Georg Brandle3a25832006-05-17 14:56:04 +0000794- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
795 and several features added, such as speed and geometry control.
796
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000797- Patch #1488881: add support for external file objects in bz2 compressed
798 tarfiles.
799
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000800- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
801 stdout arguments, making it possible to redirect input and output
802 for remote debugging.
803
804- Patch #1484695: Update the tarfile module to version 0.8. This fixes
805 a couple of issues, notably handling of long file names using the
806 GNU LONGNAME extension.
807
808- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
809 new flag when ``name`` is already the name of an option flag.
810
811- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
812 package.
813

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000850What's New in Python 2.5 alpha 2?
851=================================
852
853*Release date: 27-APR-2006*
854
855Core and builtins
856-----------------
857
Thomas Heller1b046642006-04-18 18:51:06 +0000858- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
859 by converting these apis from macros into exported functions again:
860
861 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
862 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
863 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
864 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
865 PyRun_String Py_CompileString
866
Martin v. Löwis45294a92006-04-18 06:24:08 +0000867- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
868
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000869- All uses of PyStructSequence_InitType have been changed to initialize
870 the type objects only once, even if the interpreter is initialized
871 multiple times.
872
Neal Norwitz61546162006-04-14 05:20:28 +0000873- Bug #1454485, array.array('u') could crash the interpreter. This was
874 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
875 to unicode when it didn't make sense. 'u#' now requires a unicode string.
876
877- Py_UNICODE is unsigned. It was always documented as unsigned, but
878 due to a bug had a signed value in previous versions.
879
Tim Peters3a5e8b12006-04-11 01:44:07 +0000880- Patch #837242: ``id()`` of any Python object always gives a positive
881 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
882 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000883 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000884 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000885
Tim Peters3a5e8b12006-04-11 01:44:07 +0000886 def __hash__(self):
887 return id(self) # WRONG
888
889 because a hash result must be a (short) Python int but it was always
890 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000891 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000892 was always usable as a hash value before this patch. That's no longer
893 necessarily so.
894
895- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000896 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000897 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000898 #1454844)
899
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000900- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
901 involving generators that have paused outside of any ``try`` or ``with``
902 blocks. (In 2.5a1, a paused generator that was part of a reference
903 cycle could not be garbage collected, regardless of whether it was
904 paused in a ``try`` or ``with`` block.)

918 the cachesize parameter.
919

921 a temporary db (file=None) with the 'n' flag to truncate on open.
922
923- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
924 as older versions cause excessive test failures.

Tim Peters711bf302006-04-25 03:31:36 +0000936- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
937 a doctest to be skipped (the code is not run, and the expected output
938 or exception is ignored).
939
Nick Coghlanda2268f2006-04-24 04:37:15 +0000940- Fixed contextlib.nested to cope with exceptions being raised and
941 caught inside exit handlers.
942
Greg Wardab05edc2006-04-23 03:47:58 +0000943- Updated optparse module to Optik 1.5.1 (allow numeric constants in
944 hex, octal, or binary; add ``append_const`` action; keep going if
945 gettext cannot be imported; added ``OptionParser.destroy()`` method;
946 added ``epilog`` for better help generation).
947
Tim Peters21fbd572006-04-21 21:18:10 +0000948- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
949 called from a thread spawned as a side effect of importing a module.
950
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000951- The pydoc module now supports documenting packages contained in
952 .zip or .egg files.
953
954- The pkgutil module now has several new utility functions, such
955 as ``walk_packages()`` to support working with packages that are either
956 in the filesystem or zip files.
957
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000958- The mailbox module can now modify and delete messages from
959 mailboxes, in addition to simply reading them. Thanks to Gregory
960 K. Johnson for writing the code, and to the 2005 Google Summer of
961 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000962
Tim Petersc7605f22006-04-17 21:12:33 +0000963- The ``__del__`` method of class ``local`` in module ``_threading_local``
964 returned before accomplishing any of its intended cleanup.
965

971
Anthony Baxtere29002c2006-04-12 12:07:31 +0000972- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
973 Windows. Bug #1469163.
974
Phillip J. Eby47032112006-04-11 01:07:43 +0000975- The warnings, linecache, inspect, traceback, site, and doctest modules
976 were updated to work correctly with modules imported from zipfiles or
977 via other PEP 302 __loader__ objects.
978
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000979- Patch #1467770: Reduce usage of subprocess._active to processes which
980 the application hasn't waited on.
981
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000982- Patch #1462222: Fix Tix.Grid.
983
Neal Norwitza31bf182006-04-09 03:35:43 +0000984- Fix exception when doing glob.glob('anything*/')
985
Skip Montanaro262fb922006-04-21 02:31:07 +0000986- The pstats.Stats class accepts an optional stream keyword argument to
987 direct output to an alternate file-like object.
988
Anthony Baxter51bcb682006-04-05 14:51:42 +0000989Build
990-----
991
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000992- The Makefile now has a reindent target, which runs reindent.py on
993 the library.
994
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000995- Patch #1470875: Building Python with MS Free Compiler
996
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000997- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000998
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000999- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1000 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001001 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001002 CXX from --with-cxx-main, see description in README.
1003
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001004- Patch #1429775: Link extension modules with the shared libpython.
1005
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001006- Fixed a libffi build problem on MIPS systems.
1007
Tim Peters8931ff12006-05-13 23:28:20 +00001008- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1009 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1010 and "%zu" for unsigned integers of type ``size_t``.
1011
Anthony Baxter51bcb682006-04-05 14:51:42 +00001012Tests
1013-----
1014
Nick Coghlanda2268f2006-04-24 04:37:15 +00001015- test_contextlib now checks contextlib.nested can cope with exceptions
1016 being raised and caught inside exit handlers.
1017
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001018- test_cmd_line now checks operation of the -m and -c command switches
1019
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001020- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1021 it separately and by hand. It also wasn't cleaning up its changes to
1022 the current Decimal context.
1023
Thomas Woutersabd08882006-04-26 15:53:30 +00001024- regrtest.py now has a -M option to run tests that test the new limits of
1025 containers, on 64-bit architectures. Running these tests is only sensible
1026 on 64-bit machines with more than two gigabytes of memory. The argument
1027 passed is the maximum amount of memory for the tests to use.
1028
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001029Tools

Anthony Baxter51bcb682006-04-05 14:51:42 +00001035Documentation
1036-------------
1037
Tim Petersb06d28c2006-05-12 01:57:59 +00001038- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1039
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001040- PEP 343: Added Context Types section to the library reference
1041 and attempted to bring other PEP 343 related documentation into
1042 line with the implementation and/or python-dev discussions.
1043
Tim Peters8dc73d22006-04-24 02:03:16 +00001044- Bug #1337990: clarified that ``doctest`` does not support examples
1045 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001048What's New in Python 2.5 alpha 1?
1049=================================
1050
Anthony Baxterebed3f62006-04-03 15:03:44 +00001051*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001052
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001053Core and builtins
1054-----------------
1055
Nick Coghlan43832302006-04-23 17:04:07 +00001056- PEP 338: -m command line switch now delegates to runpy.run_module
1057 allowing it to support modules in packages and zipfiles
1058
Martin v. Löwisc661b882006-04-20 04:54:23 +00001059- On Windows, .DLL is not an accepted file name extension for
1060 extension modules anymore; extensions are only found if they
1061 end in .PYD.
1062
Martin v. Löwisea62d252006-04-03 10:56:49 +00001063- Bug #1421664: sys.stderr.encoding is now set to the same value as
1064 sys.stdout.encoding.
1065
Neal Norwitz92e212f2006-04-03 04:48:37 +00001066- __import__ accepts keyword arguments.
1067
Georg Brandlccadf842006-03-31 18:54:53 +00001068- Patch #1460496: round() now accepts keyword arguments.
1069
Anthony Baxter262c00a2006-03-30 10:53:17 +00001070- Fixed bug #1459029 - unicode reprs were double-escaped.
1071
Hye-Shik Changd478f342006-03-23 12:32:36 +00001072- Patch #1396919: The system scope threads are reenabled on FreeBSD
1073 5.4 and later versions.
1074
Neal Norwitze98ccf62006-03-23 05:39:47 +00001075- Bug #1115379: Compiling a Unicode string with an encoding declaration
1076 now gives a SyntaxError.
1077
Georg Brandlabd1ff82006-03-18 07:59:59 +00001078- Previously, Python code had no easy way to access the contents of a
1079 cell object. Now, a ``cell_contents`` attribute has been added
1080 (closes patch #1170323).
1081
Tim Peterscf79aac2006-03-16 01:14:46 +00001082- Patch #1123430: Python's small-object allocator now returns an arena to
1083 the system ``free()`` when all memory within an arena becomes unused
1084 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1085 freed. Some applications will see a drop in virtual memory size now,
1086 especially long-running applications that, from time to time, temporarily
1087 use a large number of small objects. Note that when Python returns an
1088 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001089 platform C library will in turn return that memory to the operating system.
1090 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001091 appears to be effective at least on Microsoft C and gcc-based systems.
1092 Thanks to Evan Jones for hard work and patience.
1093
Georg Brandl533ff6f2006-03-08 18:09:27 +00001094- Patch #1434038: property() now uses the getter's docstring if there is
1095 no "doc" argument given. This makes it possible to legitimately use
1096 property() as a decorator to produce a read-only property.
1097
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001098- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1099 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1100 of requiring an int or long in slicing and a few other contexts, enabling
1101 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1102
Neal Norwitz995acdf2006-03-07 05:01:00 +00001103- Fixed various bugs reported by Coverity's Prevent tool.
1104
Brett Cannonbf364092006-03-01 04:25:17 +00001105- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1106 new exception base class, BaseException, which has a new message attribute.
1107 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1108 Raising a string exception now raises a DeprecationWarning.
1109
Thomas Woutersfb609f42006-02-28 16:37:25 +00001110- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1111 explicitly relative, using 'from .module import name' to mean 'from the same
1112 package as this module is in. Imports without dots still default to the
1113 old relative-then-absolute, unless 'from __future__ import
1114 absolute_import' is used.
1115
Brett Cannona7446e32006-02-27 23:39:10 +00001116- Properly check if 'warnings' raises an exception (usually when a filter set
1117 to "error" is triggered) when raising a warning for raising string
1118 exceptions.
1119
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001120- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001121 The name was removed from Include/code.h.
1122
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001123- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001124
Guido van Rossum1968ad32006-02-25 22:38:04 +00001125- Patch 1433928:
1126 - The copy module now "copies" function objects (as atomic objects).
1127 - dict.__getitem__ now looks for a __missing__ hook before raising
1128 KeyError.
1129
Tim Peters84ef21c2006-02-28 20:39:06 +00001130- PEP 343: with statement implemented. Needs ``from __future__ import
1131 with_statement``. Use of 'with' as a variable will generate a warning.
1132 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001133 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001134 The following objects have __context__ methods:
1135 - The built-in file type.
1136 - The thread.LockType type.
1137 - The following types defined by the threading module:
1138 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1139 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001140
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001141- Fix the encodings package codec search function to only search
1142 inside its own package. Fixes problem reported in patch #1433198.
1143
1144 Note: Codec packages should implement and register their own
1145 codec search function. PEP 100 has the details.
1146
Tim Peters9ea89d22006-06-04 03:26:02 +00001147- PEP 353: Using ``Py_ssize_t`` as the index type.
1148
1149- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1150 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1151 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1152 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1153 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001154
Neal Norwitzfc76d632006-01-10 06:03:13 +00001155- Patch #1400181, fix unicode string formatting to not use the locale.
1156 This is how string objects work. u'%f' could use , instead of .
1157 for the decimal point. Now both strings and unicode always use periods.
1158
Neal Norwitz671b9e32006-01-09 07:07:12 +00001159- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1160 configure would break checking curses.h.
1161
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001162- Bug #959576: The pwd module is now builtin. This allows Python to be
1163 built on UNIX platforms without $HOME set.
1164
Neal Norwitzc10978f2005-12-19 06:07:16 +00001165- Bug #1072182, fix some potential problems if characters are signed.
1166
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001167- Bug #889500, fix line number on SyntaxWarning for global declarations.
1168
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001169- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1170
Neal Norwitze7214a12005-12-18 05:03:17 +00001171- Support for converting hex strings to floats no longer works.
1172 This was not portable. float('0x3') now raises a ValueError.
1173
Barry Warsaw2a38a862005-12-18 01:27:35 +00001174- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001175 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001176 is now displayed in interactive prompt banner.
1177
Georg Brandlfa166682005-12-17 21:45:17 +00001178- Implementation of PEP 341 - Unification of try/except and try/finally.
1179 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001180 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001181
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001182- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1183 now encodes backslash correctly.
1184
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001185- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1186
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001187- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001188 and long longs.
1189
Neal Norwitz67715f02005-11-09 06:59:35 +00001190- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001191 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001192 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001193
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001194- Replaced most Unicode charmap codecs with new ones using the
1195 new Unicode translate string feature in the builtin charmap
1196 codec; the codecs were created from the mapping tables available
1197 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1198 encodings now include a mapping for the Apple logo)
1199
Tim Peterse3547fd2005-12-16 23:13:57 +00001200- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001201
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001202- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001203
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001204- A new AST parser implementation was completed. The abstract
1205 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001206 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001207
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001208- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001209 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1210
Neal Norwitz708e51a2005-10-03 04:48:15 +00001211- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1212
Neal Norwitz11bd1192005-10-03 00:54:56 +00001213- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1214 Provide a warning when a directory is passed on the command line.
1215
Neal Norwitz40d37812005-10-02 01:48:49 +00001216- Fix segfault with invalid coding.
1217
1218- SF bug #772896: unknown encoding results in MemoryError.
1219
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001220- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001221 supported a __len__() method which evaluated to False when the iterator
1222 was empty.
1223
Guido van Rossum630db602005-09-20 18:49:54 +00001224- On 64-bit platforms, when __len__() returns a value that cannot be
1225 represented as a C int, raise OverflowError.
1226
Skip Montanarof8948ca2005-09-19 03:54:46 +00001227- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001228 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001229
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001230- SF bug #893549: parsing keyword arguments was broken with a few format
1231 codes.
1232
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001233- Changes donated by Elemental Security to make it work on AIX 5.3
1234 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1235 bug #105470: test_pwd fails on 64bit system (Opteron).
1236
Guido van Rossum539c6622005-09-14 17:49:54 +00001237- Changes donated by Elemental Security to make it work on HP-UX 11 on
1238 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1239
Georg Brandl4550b8d2005-08-26 06:43:52 +00001240- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001241 (fixes bug #1119418).
1242
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001243- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1244
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001245- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1246 exceptions that cause a function to exit.
1247
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001248- The implementation of set() and frozenset() was revised to use its
1249 own internal data structure. Memory consumption is reduced by 1/3
1250 and there are modest speed-ups as well. The API is unchanged.
1251
Tim Petersde7990b2005-07-17 23:45:23 +00001252- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1253
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001254- SF bug #1229429: PyObject_CallMethod failed to decrement some
1255 reference counts in some error exit cases.
1256
Tim Petersecc6e6a2005-07-10 22:30:55 +00001257- SF bug #1185883: Python's small-object memory allocator took over
1258 a block managed by the platform C library whenever a realloc specified
1259 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001260 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001261 portable way to copy data from the C-managed block into Python's
1262 small-object space without risking a memory fault. Python's small-object
1263 realloc now leaves such blocks under the control of the platform C
1264 realloc.
1265
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001266- SF bug #1232517: An overflow error was not detected properly when
1267 attempting to convert a large float to an int in os.utime().
1268
Raymond Hettinger3296e692005-06-29 23:29:56 +00001269- SF bug #1224347: hex longs now print with lowercase letters just
1270 like their int counterparts.
1271
Michael W. Hudson188d4362005-06-20 16:52:57 +00001272- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1273 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1274 interpreter states; back out that fix and do a better job (see
1275 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1276 for a longer write-up of the problem).
1277
Michael W. Hudsondf888462005-06-03 14:41:55 +00001278- SF patch #1180995: marshal now uses a binary format by default when
1279 serializing floats.
1280
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001281- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1282 the routines that promise to produce IEEE 754 binary representations
1283 of floats now simply copy bytes around.
1284
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001285- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1286 278.
1287
Brett Cannonc3647ac2005-04-26 03:45:26 +00001288- patch #1109424: int, long, float, complex, and unicode now check for the
1289 proper magic slot for type conversions when subclassed. Previously the
1290 magic slot was ignored during conversion. Semantics now match the way
1291 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001292 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001293 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001294 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001295
Barry Warsawc8d907c2005-04-19 23:43:40 +00001296- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1297 NULL, now raise an AttributeError when attempting to set or delete the
1298 attribute. Previously a TypeError was raised, but this was inconsistent
1299 with the equivalent pure-Python implementation.
1300
Michael W. Hudson774479c2005-04-18 08:46:17 +00001301- It is now safe to call PyGILState_Release() before
1302 PyEval_InitThreads() (note that if there is reason to believe there
1303 are multiple threads around you still must call PyEval_InitThreads()
1304 before using the Python API; this fix is for extension modules that
1305 have no way of knowing if Python is multi-threaded yet).
1306
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001307- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1308 disabled caused a crash.
1309
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001310- Bug #1165306: instancemethod_new allowed the creation of a method
1311 with im_class == im_self == NULL, which caused a crash when called.
1312
Tim Petersecc6e6a2005-07-10 22:30:55 +00001313- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001314 fixes the crash seen in bug #1165761
1315
Raymond Hettinger96229b12005-03-11 06:49:40 +00001316- Added two new builtins, any() and all().
1317
Brett Cannon409d8f22005-03-05 06:47:57 +00001318- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001319 (e.g., ``class C(): pass`` is no longer a syntax error).
1320 Patch #1176012 added support to the 'parser' module and 'compiler' package
1321 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001322
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001323- Patch #1115086: Support PY_LONGLONG in structmember.
1324
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001325- Bug #1155938: new style classes did not check that __init__() was
1326 returning None.
1327
Tim Petersecc6e6a2005-07-10 22:30:55 +00001328- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001329 ('\') with a specific error message.
1330
Martin v. Löwisff232d72005-03-03 09:24:38 +00001331- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1332
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001333- Bug #1124295: the __name__ attribute of file objects was
1334 inadvertently made inaccessible in restricted mode.
1335
Tim Petersecc6e6a2005-07-10 22:30:55 +00001336- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001337 an ferror() call.
1338
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001339- min() and max() now support key= arguments with the same meaning as in
1340 list.sort().
1341
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001342- The peephole optimizer now performs simple constant folding in expressions:
1343 (2+3) --> (5).
1344
Raymond Hettingera422c342005-01-11 03:03:27 +00001345- set and frozenset objects can now be marshalled. SF #1098985.
1346
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001347- Bug #1077106: Poor argument checking could cause memory corruption
1348 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001349
Jeremy Hyltonab630502005-02-04 18:44:06 +00001350- The parser did not complain about future statements in illegal
1351 positions. It once again reports a syntax error if a future
1352 statement occurs after anything other than a doc string.
1353
Neil Schemenauercf52c072005-08-12 17:34:58 +00001354- Change the %s format specifier for str objects so that it returns a
1355 unicode instance if the argument is not an instance of basestring and
1356 calling __str__ on the argument returns a unicode instance.
1357
Tim Petersf4e69282006-02-27 17:15:31 +00001358- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1359 current thread state when the auto-GIL-state machinery knows about
1360 it (since the thread state is being deleted, continuing to remember it
1361 can't help, but can hurt if another thread happens to get created with
1362 the same thread id).
1363
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001364Extension Modules
1365-----------------
1366

Neal Norwitz10be10c2006-03-16 06:50:13 +00001380 util, whatsound, whrandom, zmod
1381
1382- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1383
1384- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001385 is deprecated. The undocumented re.engine variable no longer exists.
1386
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001387- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1388 SS2 (single-shift 2) escape sequences correctly.
1389
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001390- The unicodedata module was updated to the 4.1 version of the Unicode
1391 database. The 3.2 version is still available as unicodedata.db_3_2_0
1392 for applications that require this specific version (such as IDNA).
1393
Neal Norwitzb62c4332006-03-04 18:35:47 +00001394- The timing module is no longer built by default. It was deprecated
1395 in PEP 4 in Python 2.0 or earlier.
1396
Guido van Rossum1968ad32006-02-25 22:38:04 +00001397- Patch 1433928: Added a new type, defaultdict, to the collections module.
1398 This uses the new __missing__ hook behavior added to dict (see above).
1399
Georg Brandldbd83392006-02-20 09:42:33 +00001400- Bug #854823: socketmodule now builds on Sun platforms even when
1401 INET_ADDRSTRLEN is not defined.
1402
Georg Brandlf4f44152006-02-18 22:29:33 +00001403- Patch #1393157: os.startfile() now has an optional argument to specify
1404 a "command verb" to invoke on the file.
1405
Neal Norwitz082b2df2006-02-07 07:04:46 +00001406- Bug #876637, prevent stack corruption when socket descriptor
1407 is larger than FD_SETSIZE.
1408
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001409- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1410 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1411 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

1414 than the system default domain.
1415
Martin v. Löwis14694662006-02-03 12:54:16 +00001416- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1417 are reported, the limit on path name lengths is removed, and stat reports
1418 WindowsError now (instead of OSError).
1419
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001420- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

Michael W. Hudson8137bea2005-07-27 20:24:40 +00001494- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
1495 the request code argument, which results in more C-like behaviour
1496 for large or negative values.
1497
Tim Petersecc6e6a2005-07-10 22:30:55 +00001498- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

1507 available on the platform.
1508
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001509- Bug #1166660: The readline module could segfault if hook functions
1510 were set in a different thread than that which called readline.
1511
Raymond Hettinger4aec61e2005-03-18 21:20:23 +00001512- collections.deque objects now support a remove() method.
1513
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00001514- operator.itemgetter() and operator.attrgetter() now support retrieving

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001538- the cPickle module no longer accepts the deprecated None option in the
1539 args tuple returned by __reduce__().
1540
Raymond Hettingerb2594052004-12-05 09:25:51 +00001541- itertools.islice() now accepts None for the start and step arguments.
1542 This allows islice() to work more readily with slices:
1543 islice(s.start, s.stop, s.step)
1544
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001545- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001554- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1555 been renamed to have only a single underscore prefix. This was done to
1556 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001557
Nick Coghlan43832302006-04-23 17:04:07 +00001558- PEP 338: new module runpy defines a run_module function to support
1559 executing modules which provide access to source code or a code object
1560 via the PEP 302 import mechanisms.
1561
Anthony Baxter93f5b932006-04-03 08:05:07 +00001562- The email module's parsedate_tz function now sets the daylight savings
1563 flag to -1 (unknown) since it can't tell from the date whether it should

1570 in attribute values.
1571
Anthony Baxterc51ee692006-04-01 00:57:31 +00001572- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001573 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001574 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001575 module will not be built.
1576
Tim Petersc17976e2006-04-01 00:26:53 +00001577- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1578 aren't officially supported here, and trying to use them will probably
1579 raise an exception some day. But dicts have been allowed, and "mostly
1580 worked", so support for them won't go away without warning.
1581
Georg Brandl338ef7d2006-03-31 18:42:16 +00001582- Bug #1445068: getpass.getpass() can now be given an explicit stream
1583 argument to specify where to write the prompt.
1584
Georg Brandl22ec80b2006-03-31 18:25:44 +00001585- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1592
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001593- Queue.Queue objects now support .task_done() and .join() methods
1594 to make it easier to monitor when daemon threads have completed
1595 processing all enqueued tasks. Patch #1455676.
1596

1600
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001601- email 4.0 package now integrated. This is largely the same as the email 3.0
1602 package that was included in Python 2.3, except that PEP 8 module names are
1603 now used (e.g. mail.message instead of email.Message). The MIME classes
1604 have been moved to a subpackage (e.g. email.mime.text instead of
1605 email.MIMEText). The old names are still supported for now. Several
1606 deprecated Message methods have been removed and lots of bugs have been
1607 fixed. More details can be found in the email package documentation.
1608
Walter Dörwald40108c92006-03-27 08:15:44 +00001609- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1610 (a subclass of tuple) that provides incremental decoders and encoders
1611 (a way to use stateful codecs without the stream API). Python functions
1612 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1613 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1614 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001615
Walter Dörwald067db482006-03-15 22:17:27 +00001616- Patch #1359365: Calling next() on a closed StringIO.String object raises
1617 a ValueError instead of a StopIteration now (like file and cString.String do).
1618 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1619 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001620
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001621- A regrtest option -w was added to re-run failed tests in verbose mode.

1631
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001632- PEP 343: new module contextlib.py defines decorator @contextmanager
1633 and helpful context managers nested() and closing().
1634
Martin v. Löwis415ed932006-02-27 19:56:30 +00001635- The compiler package now supports future imports after the module docstring.
1636
Georg Brandl8f7c54e2006-02-20 08:40:38 +00001637- Bug #1413790: zipfile now sanitizes absolute archive names that are

1639
Georg Brandlc98eeed2006-02-19 14:57:47 +00001640- Patch #1215184: FileInput now can be given an opening hook which can

Martin v. Löwis3e865952006-01-24 15:51:21 +00001669 specifications, raises IOErrors when proxies for unsupported protocols
1670 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00001693 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1694 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1695 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1696 Ronald L. Rivest offered this advice for Python:
1697
1698 "The consensus of researchers in this area (at least as
1699 expressed at the NIST Hash Function Workshop 10/31/05),
1700 is that SHA-256 is a good choice for the time being, but
1701 that research should continue, and other alternatives may
1702 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001703
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001704- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl532efab2005-08-24 22:34:21 +00001749
Georg Brandlb9256022005-08-24 18:46:39 +00001750- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
1751 ContentTooShortException, when the actually downloaded size does not
1752 match the Content-Length header.
1753
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +00001754- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.
1755
Martin v. Löwis56066d22005-08-24 07:38:12 +00001756- Bug #1178484: Return complete lines from codec stream readers
1757 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001758 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001759
Georg Brandl6d2b3462005-08-24 07:36:17 +00001760- Bug #1192315: Disallow negative arguments to clear() in pdb.

1773
Georg Brandla4a8b822005-07-15 09:13:21 +00001774- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
1775 parameter, but uses the usual "kwargs=None".
1776
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001777- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00001778 Patch #1209527 (Contributed by Connelly).
1779
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00001780- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
1781 to W3C name (404 -> 'Not Found'). RFE #1216944.
1782
Georg Brandl9e43acf2005-07-04 17:16:07 +00001783- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1784 as this can cause problems with apps closing all file descriptors.
1785
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001786- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001787 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00001788
Georg Brandl2f210b62005-06-26 22:09:06 +00001789- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
1790
Georg Brandlfbff1bc2005-06-26 21:36:25 +00001791- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
1792 error messages.

Georg Brandl379f99d2005-06-26 21:09:38 +00001794- Bug #1108948: Cookie.py produced invalid JavaScript code.
1795
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001796- The tokenize module now detects and reports indentation errors.
1797 Bug #1224621.
1798
Raymond Hettinger68c04532005-06-10 11:05:19 +00001799- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001800 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001801 the generate_tokens() function now accepts a callable argument that
1802 terminates by raising StopIteration.
1803
Georg Brandl9166e1a2005-06-04 09:20:03 +00001804- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1805
Georg Brandl268e61c2005-06-03 14:28:50 +00001806- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1807 component of the path.
1808
Skip Montanaro174dd222005-05-14 20:54:16 +00001809- Patch #1120353: The xmlrpclib module provides better, more transparent,
1810 support for datetime.{datetime,date,time} objects. With use_datetime set
1811 to True, applications shouldn't have to fiddle with the DateTime wrapper
1812 class at all.
1813
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001814- distutils.commands.upload was added to support uploading distribution
1815 files to PyPI.
1816
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001817- distutils.commands.register now encodes the data as UTF-8 before posting
1818 them to PyPI.
1819
Raymond Hettinger267b8682005-03-27 10:47:39 +00001820- decimal operator and comparison methods now return NotImplemented
1821 instead of raising a TypeError when interacting with other types. This
1822 allows other classes to implement __radd__ style methods and have them
1823 work as expected.
1824
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001825- Bug #1163325: Decimal infinities failed to hash. Attempting to
1826 hash a NaN raised an InvalidOperation instead of a TypeError.
1827
Tim Petersecc6e6a2005-07-10 22:30:55 +00001828- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001829 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1830

Martin v. Löwisa4dac402005-03-03 11:39:45 +00001840 profile.py if available.
1841
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001842- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.

1862
Guido van Rossumd0641422005-02-03 15:01:24 +00001863- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1864 disables recursive traversal through instance attributes, which can
1865 be exploited in various ways.
1866
Tim Peterse3547fd2005-12-16 23:13:57 +00001867- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001868 flags on the HTTP listening socket.
1869
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001870- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1871 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1872
Fred Drakefbdeaad2006-07-29 16:56:15 +00001873- Patches #893642, #1039083: add allow_none, encoding arguments to
1874 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001875
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001876- Bug #1110478: Revert os.environ.update to do putenv again.
1877
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001878- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1879
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001880- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1881
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001882- Enhancements to the csv module:
1883
1884 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001885 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001886 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001887 + Dialect parameter parsing has been re-implemented to improve error
1888 reporting.
1889 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1890 dictates.
1891 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001892 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001893 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001894 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1895 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001896 + reader now allows \r characters to be quoted (previously it only allowed
1897 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001898 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001899 + Dialect classes passed to the module are no longer instantiated by
1900 the module before being parsed (the former validation scheme required
1901 this, but the mechanism was unreliable).
1902 + The dialect registry now contains instances of the internal
1903 C-coded dialect type, rather than references to python objects.
1904 + the internal c-coded dialect type is now immutable.
1905 + register_dialect now accepts the same keyword dialect specifications
1906 as the reader and writer, allowing the user to register dialects
1907 without first creating a dialect class.
1908 + a configurable limit to the size of parsed fields has been added -
1909 previously, an unmatched quote character could result in the entire
1910 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001911 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001912 the parser field size limit (returning the former limit). The initial
1913 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001914 + A line_num attribute has been added to the reader object, which tracks
1915 the number of lines read from the source iterator. This is not
1916 the same as the number of records returned, as records can span
1917 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001918 + reader and writer objects were not being registered with the cyclic-GC.
1919 This has been fixed.
1920
Brett Cannone6539c42005-01-08 02:43:53 +00001921- _DummyThread objects in the threading module now delete self.__block that is
1922 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1923 lock primitives tend to be limited in number and thus should not be wasted on
1924 a _DummyThread object. Fixes bug #1089632.
1925
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001926- The imghdr module now detects Exif files.
1927
Raymond Hettinger6065d322004-12-20 23:51:53 +00001928- StringIO.truncate() now correctly adjusts the size attribute.
1929 (Bug #951915).
1930
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001931- locale.py now uses an updated locale alias table (built using
1932 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1933 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001934 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001935
Raymond Hettinger3557f422004-12-07 12:02:02 +00001936- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1937
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001938- the pickle module no longer accepts the deprecated None option in the
1939 args tuple returned by __reduce__().
1940
Brett Cannon84667c02004-12-07 03:25:18 +00001941- optparse now optionally imports gettext. This allows its use in setup.py.
1942
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001943- the pickle module no longer uses the deprecated bin parameter.
1944
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001945- the shelve module no longer uses the deprecated binary parameter.
1946
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001947- the pstats module no longer uses the deprecated ignore() method.
1948
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001949- the filecmp module no longer uses the deprecated use_statcache argument.
1950
Raymond Hettinger664347b2004-12-04 21:21:53 +00001951- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1952 extended or overridden by subclasses. Formerly, the subclassed method would
1953 be ignored by the rest of the module. (Bug #1078905).
1954
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001955- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001956 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001957
Walter Dörwald36733692004-12-22 12:50:50 +00001958- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1959 once when a size argument is given. This prevents a buffer overflow in the
1960 tokenizer with very long source lines.
1961
Barry Warsaw538561e2006-01-01 21:48:54 +00001962- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1963 immediately after creating the object, without any intervening
1964 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001965
Skip Montanaro05885812005-01-16 20:48:27 +00001966- The reconvert.quote function can now emit triple-quoted strings. The
1967 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001968
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001969- ``UserString.MutableString`` now supports negative indices in
1970 ``__setitem__`` and ``__delitem__``
1971
Greg Ward40407942005-03-05 02:53:17 +00001972- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1973 correctly.
1974
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001975- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1976 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1977 character even if the user has passed a size parameter to get a proper
1978 line ending. Remove the special handling of a "\r\n" that has been split
1979 between two lines.
1980
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001981- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1982 about illegal code points. The codec now supports PEP 293 style error
1983 handlers.
1984
Walter Dörwald78a78b02005-09-01 12:04:29 +00001985- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001986 from the input stream, so that the output is a byte string in the correct
1987 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001988
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001989- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1990 considering it exactly like a '*'.
1991
Walter Dörwald007f8df2005-10-09 19:42:27 +00001992- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1993 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001994
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001995- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1996
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001997- Patch #1413711: Certain patterns of differences were making difflib
1998 touch the recursion limit.
1999
Walter Dörwald58917a62006-03-31 15:26:22 +00002000- Bug #947906: An object oriented interface has been added to the calendar
2001 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002002 called as a script (e.g. via ``python -mcalendar``). Localized month and
2003 weekday names can be ouput (even if an exotic encoding is used) using
2004 special classes that use unicode.

2007-----
2008
Neal Norwitz602d3392006-03-31 08:21:40 +00002009- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2010 by using -mieee gcc option.
2011

2013
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002014- Build support for Win64-AMD64 was added.
2015
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002016- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2017
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002018- Patch #881820: look for openpty and forkpty also in libbsd.
2019
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002020- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2021 The zlib module is now builtin on Windows.
2022
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002023- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2024
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002025- Bug #1189330: configure did not correctly determine the necessary
2026 value of LINKCC if python was built with GCC 4.0.
2027
Trent Mick8321b422005-07-26 02:29:21 +00002028- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2029 vulnerability in zlib 1.2.1 and 1.2.2.
2030
Brett Cannon08cd5982005-04-24 22:26:38 +00002031- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2032 flags that change binary compatibility. Changes were also made to
2033 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002034 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002035
Bob Ippolitoed233462005-03-29 13:47:59 +00002036- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2037 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2038 no longer exists). This configure patch makes things right.
2039
Martin v. Löwise2713be2005-03-08 15:03:08 +00002040- Bug #1158607: Build with --disable-unicode again.
2041
Brett Cannon46d96232005-02-16 00:07:19 +00002042- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2043 defined. Discovered as a result of not being able to build on OS X.
2044
Brett Cannon516592f2004-12-07 00:42:59 +00002045- setup.py now uses the directories specified in LDFLAGS using the -L option
2046 and in CPPFLAGS using the -I option for adding library and include
2047 directories, respectively, for compiling extension modules against. This has
2048 led to the core being compiled using the values in CPPFLAGS. It also removes
2049 the need for the special-casing of both DarwinPorts and Fink for darwin since
2050 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2051 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2052 Fink, ``-I/opt/local/include`` for DarwinPorts).
2053
Brett Cannon43802422005-02-10 20:48:03 +00002054- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2055 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2056 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2057 Closes bug #1096244. Thanks Gregory Bond.

2060-----
2061
Tim Petersc9d78aa2006-03-26 23:27:58 +00002062- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2063 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2064 is obtained via the ``PyObject_`` family, it must be released via the
2065 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2066 always been officially true, but when Python's small-object allocator was
2067 introduced, an attempt was made to cater to a few extension modules
2068 discovered at the time that obtained memory via ``PyObject_New`` but
2069 released it via ``PyMem_DEL``. It's years later, and if such code still
2070 exists it will fail now (probably with segfaults, but calling wrong
2071 low-level memory management functions can yield many symptoms).
2072
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002073- Added a C API for set and frozenset objects.
2074
Raymond Hettinger66517482004-12-03 11:45:13 +00002075- Removed PyRange_New().
2076
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002077- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2078 mapping argument now. This string is used as a mapping table. Byte values
2079 greater than the length of the string and 0xFFFE are treated as undefined
2080 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002087
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002088- Patch #1276356: New resource "urlfetch" is implemented. This enables
2089 even impatient people to run tests that require remote files.
