Fred Drake53912162006-07-29 13:22:49 +00007What's New in Python 2.5 beta 3?
8================================
Neal Norwitza1f10902006-07-12 07:28:29 +00009
Anthony Baxter5d32a9f2006-08-02 07:43:09 +000010*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +000011
12Core and builtins
13-----------------
14
Neal Norwitzc5e060d2006-08-02 06:14:22 +000015- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t, it previously
16 returned a long (see PEP 353).
17
Neal Norwitzf71ec5a2006-07-30 06:57:04 +000018- Bug #1515471: string.replace() accepts character buffers again.
19
Neal Norwitz07aadb12006-07-30 06:55:48 +000020- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
21 This provides the proper warning for struct.pack().
22 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
23
Neal Norwitz0d62a062006-07-30 06:53:31 +000024- Patch #1531113: Fix augmented assignment with yield expressions.
25 Also fix a SystemError when trying to assign to yield expressions.
26
Phillip J. Ebyf7575d02006-07-28 21:12:07 +000027- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
28 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
29 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
30 excessive filesystem operations during imports.
31
Tim Petersbc24eee2006-07-27 01:14:53 +000032- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
33 operations on signed longs that are formally undefined by C.
34 Unfortunately, at least one compiler now cares about that, so complicated
35 the code to make that compiler happy again.
36
Martin v. Löwis982e9fe2006-07-24 12:54:17 +000037- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
38
Martin v. Löwisd22968a2006-07-24 11:54:53 +000039- Patch #1232023: Stop including current directory in search
40 path on Windows.
41
Neal Norwitze1fdb322006-07-21 05:32:28 +000042- Fix some potential crashes found with failmalloc.
43
Neal Norwitze7563102006-07-17 01:00:16 +000044- Fix warnings reported by Klocwork's static analysis tool.
45
Neal Norwitz84be93b2006-07-16 01:50:38 +000046- Bug #1512814, Fix incorrect lineno's when code within a function
47 had more than 255 blank lines.
48
Georg Brandl9dceedb2006-07-12 15:31:17 +000049- Patch #1521179: Python now accepts the standard options ``--help`` and
50 ``--version`` as well as ``/?`` on Windows.
51
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +000052- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +000053 again. Fixing this problem required changing the .pyc magic number.
54 This means that .pyc files generated before 2.5c1 will be regenerated.
55
Tim Peters112aad32006-07-19 00:03:19 +000056- Bug #1524317: Compiling Python ``--without-threads`` failed.
57 The Python core compiles again then, and, in a build without threads, the
58 new ``sys._current_frames()`` returns a dictionary with one entry,
59 mapping the faux "thread id" 0 to the current frame.
60
Ronald Oussoren3075e162006-07-25 20:28:55 +000061- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +000062
Ronald Oussoren3075e162006-07-25 20:28:55 +000063
Neal Norwitza1f10902006-07-12 07:28:29 +000064Library
65-------
66
Martin v. Löwis961b91b2006-08-02 13:53:55 +000067- Correction of patch #1455898: In the mbcs decoder, set final=False
68 for stream decoder, but final=True for the decode function.
69
Georg Brandl07fec3a2006-08-01 18:49:24 +000070- os.urandom no longer masks unrelated exceptions like SystemExit or
71 KeyboardInterrupt.
72
Martin v. Löwis4e678382006-07-30 13:00:31 +000073- Bug #1525866: Don't copy directory stat times in
74 shutil.copytree on Windows
75
Georg Brandle34ac7c2006-07-30 11:07:23 +000076- Bug #1002398: The documentation for os.path.sameopenfile now correctly
77 refers to file descriptors, not file objects.
78
Fred Drakefbdeaad2006-07-29 16:56:15 +000079- Rename of the xml package to xmlcore, and the import hackery done to
80 make it appear at both names, has been removed. Bug #1511497,
81 #1513611, and probably others.
82
Georg Brandledd9b0d2006-07-29 09:33:26 +000083- Bug #1441397: The compiler module now recognizes module and function
84 docstrings correctly as it did in Python 2.4.
85
Tim Peters6f681472006-07-27 23:44:37 +000086- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
87 lost that tests are sorted by name before being run. This rarely
88 matters for well-written tests, but can create baffling symptoms if
89 side effects from one test to the next affect outcomes. ``DocTestFinder``
90 has been changed to sort the list of tests it returns.
91
Martin v. Löwis1f30c372006-07-30 13:14:05 +000092- The distutils version has been changed to 2.5.0, and are now kept
93 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +000094
Martin v. Löwis9298eff2006-07-26 12:12:56 +000095- Bug #978833: Really close underlying socket in _socketobject.close.
96
Georg Brandl0619a322006-07-26 07:40:17 +000097- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
98 with title().
99
Georg Brandlcf0c1722006-07-26 07:23:32 +0000100- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
101 to recursive calls and call it with the failing package name.
102
Martin v. Löwis0b483032006-07-25 09:53:12 +0000103- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
104
Georg Brandlc13c34c2006-07-24 14:09:56 +0000105- Patch #1515343: Fix printing of deprecated string exceptions with a
106 value in the traceback module.
107
Greg Ward48fae7a2006-07-23 16:05:51 +0000108- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
109
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000110- Patch #1524429: Use repr() instead of backticks in Tkinter again.
111
Brett Cannoncaebe222006-07-18 04:41:36 +0000112- Bug #1520914: Change time.strftime() to accept a zero for any position in its
113 argument tuple. For arguments where zero is illegal, the value is forced to
114 the minimum value that is correct. This is to support an undocumented but
115 common way people used to fill in inconsequential information in the time
116 tuple pre-2.4.
117
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000118- Patch #1220874: Update the binhex module for Mach-O.
119
Barry Warsawb110bad2006-07-21 14:51:07 +0000120- The email package has improved RFC 2231 support, specifically for
121 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
122 (name*0=<blah>) parameter continuations. This may change the types of
123 values returned from email.message.Message.get_param() and friends.
124 Specifically in some cases where non-encoded continuations were used,
125 get_param() used to return a 3-tuple of (None, None, string) whereas now it
126 will just return the string (since non-encoded continuations don't have
127 charset and language parts).
128
129 Also, whereas % values were decoded in all parameter continuations, they are
130 now only decoded in encoded parameter parts.
131
Ronald Oussoren3075e162006-07-25 20:28:55 +0000132- Bug #1517990: IDLE keybindings on MacOS X now work correctly
133
134- Bug #1517996: IDLE now longer shows the default Tk menu when a
135 path browser, class browser or debugger is the frontmost window on MacOS X
136
Barry Warsaw00decd72006-07-27 23:43:15 +0000137- Patch #1520294: Support for getset and member descriptors in types.py,
138 inspect.py, and pydoc.py. Specifically, this allows for querying the type
139 of an object against these built-in types and more importantly, for getting
140 their docstrings printed in the interactive interpreter's help() function.
141
Ronald Oussoren3075e162006-07-25 20:28:55 +0000142
Neal Norwitza1f10902006-07-12 07:28:29 +0000143Extension Modules
144-----------------
145
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000146- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
147 a socket operation on a socket with a timeout, the exception will be
148 caught correctly. Previously, the exception was not caught.
149
Thomas Heller1393d6a2006-07-28 21:43:20 +0000150- Patch #1529514: The _ctypes extension is now compiled on more
151 openbsd target platforms.
152
Tim Peters9cab5932006-07-28 00:30:00 +0000153- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
154 a memory leak, affecting pickles and deep copies.
155
Tim Petersbc24eee2006-07-27 01:14:53 +0000156- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000157 Paul Eggert.
158
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000159- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
160
Thomas Hellerce049a02006-07-14 17:51:14 +0000161- Patch #1521817: Index range checking on ctypes arrays containing
162 exactly one element enabled again. This allows iterating over these
163 arrays, without the need to check the array size before.
164
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000165- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000166 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000167 /dev/null in certain cases; this is now fixed.
168
Thomas Heller47d7a062006-07-12 08:43:47 +0000169- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
170 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000171
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000172- Because of a misspelled preprocessor symbol, ctypes was always
173 compiled without thread support; this is now fixed.
174
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000175- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
176 methods now allow their database parameter to be None as the
177 sleepycat API allows.
178
Matt Flemingec926502006-07-28 11:27:27 +0000179- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
180 bluetooth API compared with Linux and FreeBSD.
181
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000182Tests
183-----
184
185- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
186 how long the test file should take to play. Now accepts taking 2.93 secs
187 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
188
Georg Brandl4793aa32006-07-28 18:31:39 +0000189- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
190 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
191 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000192
Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000193Build
194-----
195
196- Bug #1439538: Drop usage of test -e in configure as it is not portable.
197
Ronald Oussoren26cad082006-08-01 21:00:57 +0000198Mac
199---
200
201- PythonLauncher now works correctly when the path to the script contains
202 characters that are treated specially by the shell (such as quotes).
203
204- Bug #1527397: PythonLauncher now launches scripts with the working directory
205 set to the directory that contains the script instead of the user home
206 directory. That latter was an implementation accident and not what users
207 expect.
208
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000209
Georg Brandlad29e632006-06-21 17:45:17 +0000210What's New in Python 2.5 beta 2?
211================================

Anthony Baxter70e8e872006-07-10 07:41:04 +0000213*Release date: 11-JUL-2006*
Georg Brandlad29e632006-06-21 17:45:17 +0000214
215Core and builtins
216-----------------
217
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000218- Bug #1441486: The literal representation of -(sys.maxint - 1)
219 again evaluates to a int object, not a long.
220
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000221- Bug #1501934: The scope of global variables that are locally assigned
222 using augmented assignment is now correctly determined.
223
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000224- Bug #927248: Recursive method-wrapper objects can now safely
225 be released.
226
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000227- Bug #1417699: Reject locale-specific decimal point in float()
228 and atof().
229
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000230- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
231 omit a default "error" argument for NULL pointer. This allows
232 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000233
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000234- Bug #1519018: 'as' is now validated properly in import statements.
235
Neal Norwitz28746ab2006-07-09 22:14:42 +0000236- On 64 bit systems, int literals that use less than 64 bits are
237 now ints rather than longs.
238
Neal Norwitzed657552006-07-10 00:04:44 +0000239- Bug #1512814, Fix incorrect lineno's when code at module scope
240 started after line 256.
241
Tim Peters32a83612006-07-10 21:08:24 +0000242- New function ``sys._current_frames()`` returns a dict mapping thread
243 id to topmost thread stack frame. This is for expert use, and is
244 especially useful for debugging application deadlocks. The functionality
245 was previously available in Fazal Majid's ``threadframe`` extension
246 module, but it wasn't possible to do this in a wholly threadsafe way from
247 an extension.
248
Georg Brandlad29e632006-06-21 17:45:17 +0000249Library
250-------

256
Tim Peters32a83612006-07-10 21:08:24 +0000257- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000258 environment variable to be set in order to the SDK environment
259 for finding the compiler, include files, etc.
260

264
Thomas Woutersadd19112006-07-05 11:03:49 +0000265- string.Template() now correctly handles tuple-values. Previously,
266 multi-value tuples would raise an exception and single-value tuples would
267 be treated as the value they contain, instead.
268
Martin v. Löwisede77f52006-07-03 13:01:35 +0000269- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

276 degrees and radians.
277
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000278- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000279 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000280
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000281- Bug #1514703: Only setup canvas window in turtle when the canvas
282 is created.
283
Martin v. Löwis7596e832006-07-01 15:33:37 +0000284- Bug #1513223: .close() of a _socketobj now releases the underlying
285 socket again, which then gets closed as it becomes unreferenced.
286
Fred Drake10497c82006-06-29 02:57:48 +0000287- Bug #1504333: Make sgmllib support angle brackets in quoted
288 attribute values.
289
290- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
291 sgmllib ('[' and ']' were not accepted).
292
Georg Brandl1be63af2006-06-28 20:23:25 +0000293- Fix a bug in the turtle module's end_fill function.
294
Brett Cannon53ab5b72006-06-22 16:49:14 +0000295- Bug #1510580: The 'warnings' module improperly required that a Warning
296 category be either a types.ClassType and a subclass of Warning. The proper
297 check is just that it is a subclass with Warning as the documentation states.
298
Georg Brandlad29e632006-06-21 17:45:17 +0000299- The compiler module now correctly compiles the new try-except-finally
300 statement (bug #1509132).
301
Neal Norwitz60373cd2006-06-22 06:30:50 +0000302- The wsgiref package is now installed properly on Unix.
303
Vinay Sajip28e57612006-07-01 10:45:20 +0000304- A bug was fixed in logging.config.fileConfig() which caused a crash on
305 shutdown when fileConfig() was called multiple times.
306
Gerhard Häring762fbd32006-07-02 17:48:30 +0000307- The sqlite3 module did cut off data from the SQLite database at the first
308 null character before sending it to a custom converter. This has been fixed

Tim Peters112aad32006-07-19 00:03:19 +0000314- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
315 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
316 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000317
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000318- Assigning None to pointer type fields in ctypes structures possible
319 overwrote the wrong fields, this is fixed now.
320
321- Fixed a segfault in _ctypes when ctypes.wintypes were imported
322 on non-Windows platforms.
323
324- Bug #1518190: The ctypes.c_void_p constructor now accepts any
325 integer or long, without range checking.
326
327- Patch #1517790: It is now possible to use custom objects in the ctypes
328 foreign function argtypes sequence as long as they provide a from_param
329 method, no longer is it required that the object is a ctypes type.
330
331- The '_ctypes' extension module now works when Python is configured
332 with the --without-threads option.
333
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000334- Bug #1513646: os.access on Windows now correctly determines write
335 access, again.
336
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000337- Bug #1512695: cPickle.loads could crash if it was interrupted with
338 a KeyboardInterrupt.
339
Neal Norwitza12aa882006-07-06 06:45:08 +0000340- Bug #1296433: parsing XML with a non-default encoding and
341 a CharacterDataHandler could crash the interpreter in pyexpat.
342
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000343- Patch #1516912: improve Modules support for OpenVMS.

347
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000348- Automate Windows build process for the Win64 SSL module.
349
Tim Peters32a83612006-07-10 21:08:24 +0000350- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000351 Previously, the slight difference could cause compilation errors of the
352 'zlib' module on systems with more than one version of zlib.
353
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000354- The MSI compileall step was fixed to also support a TARGETDIR
355 with spaces in it.
356
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000357- Bug #1517388: sqlite3.dll is now installed on Windows independent
358 of Tcl/Tk.
359
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000360- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000361 trying to be installed even though it's empty.

384Core and builtins
385-----------------
386
Georg Brandla56b9152006-06-19 06:35:54 +0000387- Patch #1507676: Error messages returned by invalid abstract object operations
388 (such as iterating over an integer) have been improved and now include the
389 type of the offending object to help with debugging.
390
Brett Cannonea3912b2006-06-13 21:46:41 +0000391- Bug #992017: A classic class that defined a __coerce__() method that returned
392 its arguments swapped would infinitely recurse and segfault the interpreter.
393
Neal Norwitz909eb122006-06-12 02:13:21 +0000394- Fix the socket tests so they can be run concurrently.
395
Neal Norwitzb9845e72006-06-12 02:11:18 +0000396- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000397 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000398
Brett Cannon22565aa2006-06-09 22:31:23 +0000399- Bug #532646: object.__call__() will continue looking for the __call__
400 attribute on objects until one without one is found. This leads to recursion
401 when you take a class and set its __call__ attribute to an instance of the
402 class. Originally fixed for classic classes, but this fix is for new-style.
403 Removes the infinite_rec_3 crasher.
404
Georg Brandl24250812006-06-09 18:45:48 +0000405- The string and unicode methods startswith() and endswith() now accept
406 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
407
Brett Cannonde3b0522006-06-08 17:00:45 +0000408- Buffer objects, at the C level, never used the char buffer
409 implementation even when the char buffer for the wrapped object was
410 explicitly requested (originally returned the read or write buffer).
411 Now a TypeError is raised if the char buffer is not present but is
412 requested.
413
Georg Brandlddbaa662006-06-04 21:56:52 +0000414- Patch #1346214: Statements like "if 0: suite" are now again optimized
415 away like they were in Python 2.4.
416
Georg Brandlb7c8f542006-05-27 12:30:25 +0000417- Builtin exceptions are now full-blown new-style classes instead of
418 instances pretending to be classes, which speeds up exception handling
419 by about 80% in comparison to 2.5a2.
420
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000421- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
422 Unicode 4.1.
423
Georg Brandlf4ef1162006-05-26 18:03:31 +0000424- Patch #921466: sys.path_importer_cache is now used to cache valid and
425 invalid file paths for the built-in import machinery which leads to
426 fewer open calls on startup.
427
Tim Peters696cf432006-05-24 21:10:40 +0000428- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
429 of-2 bases. The largest speedup is for inputs with about 1000 decimal
430 digits. Conversion from non-power-of-2 bases remains quadratic-time in
431 the number of input digits (it was and remains linear-time for bases
432 2, 4, 8, 16 and 32).
433
Tim Petersb713ec22006-05-23 18:45:30 +0000434- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
435 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
436 an integer close to ``sys.maxint``. This was repaired by patch
437 #1335972, which also gives a nice speedup.
438
Richard Jonescebbefc2006-05-23 18:28:17 +0000439- Patch #1337051: reduced size of frame objects.
440
441- PyErr_NewException now accepts a tuple of base classes as its
442 "base" parameter.
443
Richard Jones7c88dcc2006-05-23 10:37:38 +0000444- Patch #876206: function call speedup by retaining allocated frame
445 objects.
446
Georg Brandl7b90e162006-05-18 07:01:27 +0000447- Bug #1462152: file() now checks more thoroughly for invalid mode
448 strings and removes a possible "U" before passing the mode to the
449 C library function.
450
Neal Norwitz1004a532006-05-15 07:17:23 +0000451- Patch #1488312, Fix memory alignment problem on SPARC in unicode
452
Neal Norwitz373f0a72006-05-15 07:04:36 +0000453- Bug #1487966: Fix SystemError with conditional expression in assignment
454
Martin v. Löwis879768d2006-05-11 13:28:43 +0000455- WindowsError now has two error code attributes: errno, which carries
456 the error values from errno.h, and winerror, which carries the error
457 values from winerror.h. Previous versions put the winerror.h values
458 (from GetLastError()) into the errno attribute.
459
Martin v. Löwis77736712006-05-04 05:51:03 +0000460- Patch #1475845: Raise IndentationError for unexpected indent.
461
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000462- Patch #1479181: split open() and file() from being aliases for each other.
463
Tim Peters44bd9862006-06-01 13:49:23 +0000464- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
465 methods were always silently ignored by dictionaries when comparing keys.
466 They are now passed through (except when using the C API function
467 ``PyDict_GetItem()``, whose semantics did not change).
468
469- Bug #1456209: In some obscure cases it was possible for a class with a
470 custom ``__eq__()`` method to confuse dict internals when class instances
471 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
472 No, you don't have any code that did this ;-)

480
Brett Cannon6ee7d012006-06-08 16:23:04 +0000481- Change binascii.hexlify to accept a read-only buffer instead of only a char
482 buffer and actually follow its documentation.
483
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000484- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
485
Nick Coghlanc649ec52006-05-29 12:43:05 +0000486- Patch #1478788 (modified version): The functional extension module has
487 been renamed to _functools and a functools Python wrapper module added.
488 This provides a home for additional function related utilities that are
489 not specifically about functional programming. See PEP 309.
490
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000491- Patch #1493701: performance enhancements for struct module.
492
Georg Brandl378d5922006-05-17 14:26:50 +0000493- Patch #1490224: time.altzone is now set correctly on Cygwin.
494
Georg Brandl8d3342b2006-05-16 07:38:27 +0000495- Patch #1435422: zlib's compress and decompress objects now have a
496 copy() method.
497
Andrew MacIntyre92913322006-06-13 15:04:24 +0000498- Patch #1454481: thread stack size is now tunable at runtime for thread
499 enabled builds on Windows and systems with Posix threads support.
500
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000501- On Win32, os.listdir now supports arbitrarily-long Unicode path names
502 (up to the system limit of 32K characters).
503
504- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
505 As a result, these functions now raise WindowsError instead of OSError.
506
Tim Peters7a822da2006-05-25 21:50:17 +0000507- ``time.clock()`` on Win64 should use the high-performance Windows
508 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
509 Windows platforms).
510
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000511- Calling Tk_Init twice is refused if the first call failed as that
512 may deadlock.
513
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000514- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
515 accept it without potentially using an uninitialized pointer.
516
517- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
518 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
519 patch numbers 1494885 and 1494902]

Gregory P. Smith372b5832006-06-05 18:48:21 +0000521- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000522 [pybsddb project SF patch number 1466734]
523
Gregory P. Smith372b5832006-06-05 18:48:21 +0000524- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
525 parameter is supplied. [SF pybsddb bug #1477863]
526
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000527- bsddb: the __len__ method of a DB object has been fixed to return correct
528 results. It could previously incorrectly return 0 in some cases.
529 Fixes SF bug 1493322 (pybsddb bug 1184012).
530
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000531- bsddb: the bsddb.dbtables Modify method now raises the proper error and
532 aborts the db transaction safely when a modifier callback fails.
533 Fixes SF python patch/bug #1408584.
534
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000535- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000536 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000537 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
538 database calls that would previously deadlock. [SF python bug #775414]

562 mime.types file for determining MIME types.
563
Georg Brandl2605ca82006-06-14 06:08:31 +0000564- Bug #1339007: Shelf objects now don't raise an exception in their
565 __del__ method when initialization failed.
566
Martin v. Löwisd8251432006-06-14 05:21:04 +0000567- Patch #1455898: The MBCS codec now supports the incremental mode for
568 double-byte encodings.
569
Tim Peters43898b42006-06-14 04:09:25 +0000570- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
571 guarantee that adjacent triples in the return list always describe
572 non-adjacent blocks. Previously, a pair of matching blocks could end
573 up being described by multiple adjacent triples that formed a partition
574 of the matching pair.
575
Greg Ward0e0c9f42006-06-11 16:24:11 +0000576- Bug #1498146: fix optparse to handle Unicode strings in option help,
577 description, and epilog.
578

582 clarify docs.
583
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000584- The wsgiref package has been added to the standard library.
585
Nick Coghlan676725d2006-06-08 13:54:49 +0000586- The functions update_wrapper() and wraps() have been added to the functools
587 module. These make it easier to copy relevant metadata from the original
588 function when writing wrapper functions.
589
Tim Petersd6a9eef2006-06-05 01:48:21 +0000590- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
591 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000592
Martin v. Löwis3f767792006-06-04 19:36:28 +0000593- Patch #1359618: Speed up charmap encoder by using a trie structure
594 for lookup.
595
Tim Petersd609b1a2006-06-02 23:22:51 +0000596- The functions in the ``pprint`` module now sort dictionaries by key
597 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
598 if and only if its display required more than one line, although that
599 wasn't documented. The new behavior increases predictability; e.g.,
600 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
601
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000602- Patch #1497027: try HTTP digest auth before basic auth in urllib2
603 (thanks for J. J. Lee).
604
Georg Brandl2b330372006-05-28 20:23:12 +0000605- Patch #1496206: improve urllib2 handling of passwords with respect to
606 default HTTP and HTTPS ports.
607
George Yoshidaf3c65de2006-05-28 16:39:09 +0000608- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.

Georg Brandlb89316f2006-05-17 15:51:16 +0000612- Patch #1180296: Two new functions were added to the locale module:
613 format_string() to get the effect of "format % items" but locale-aware,
614 and currency() to format a monetary number with currency sign.
615
Georg Brandle3a25832006-05-17 14:56:04 +0000616- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
617 and several features added, such as speed and geometry control.
618

620 tarfiles.
621
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000622- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
623 stdout arguments, making it possible to redirect input and output
624 for remote debugging.
625
626- Patch #1484695: Update the tarfile module to version 0.8. This fixes
627 a couple of issues, notably handling of long file names using the
628 GNU LONGNAME extension.
629
630- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
631 new flag when ``name`` is already the name of an option flag.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000672What's New in Python 2.5 alpha 2?
673=================================
674
675*Release date: 27-APR-2006*
676
677Core and builtins
678-----------------
679
Thomas Heller1b046642006-04-18 18:51:06 +0000680- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
681 by converting these apis from macros into exported functions again:
682
683 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
684 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
685 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
686 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
687 PyRun_String Py_CompileString
688
Martin v. Löwis45294a92006-04-18 06:24:08 +0000689- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
690
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000691- All uses of PyStructSequence_InitType have been changed to initialize
692 the type objects only once, even if the interpreter is initialized
693 multiple times.
694
Neal Norwitz61546162006-04-14 05:20:28 +0000695- Bug #1454485, array.array('u') could crash the interpreter. This was
696 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
697 to unicode when it didn't make sense. 'u#' now requires a unicode string.
698
699- Py_UNICODE is unsigned. It was always documented as unsigned, but
700 due to a bug had a signed value in previous versions.
701
Tim Peters3a5e8b12006-04-11 01:44:07 +0000702- Patch #837242: ``id()`` of any Python object always gives a positive
703 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
704 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000705 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000706 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000707
Tim Peters3a5e8b12006-04-11 01:44:07 +0000708 def __hash__(self):
709 return id(self) # WRONG
710
711 because a hash result must be a (short) Python int but it was always
712 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000713 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000714 was always usable as a hash value before this patch. That's no longer
715 necessarily so.
716
717- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000718 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000719 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000720 #1454844)
721
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000722- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
723 involving generators that have paused outside of any ``try`` or ``with``
724 blocks. (In 2.5a1, a paused generator that was part of a reference
725 cycle could not be garbage collected, regardless of whether it was
726 paused in a ``try`` or ``with`` block.)

732 is a macro.
733
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000734- Bug #1467952: os.listdir() now correctly raises an error if readdir()
735 fails with an error condition.
736
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000737- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
738
739- Bug #1117761: bsddb.*open() no longer raises an exception when using
740 the cachesize parameter.
741
742- Bug #1149413: bsddb.*open() no longer raises an exception when using
743 a temporary db (file=None) with the 'n' flag to truncate on open.
744
745- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
746 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000747
Armin Rigoa9017c32006-04-19 11:50:27 +0000748- Patch #1062014: AF_UNIX sockets under Linux have a special
749 abstract namespace that is now fully supported.
750
Anthony Baxter51bcb682006-04-05 14:51:42 +0000751Library
752-------
753
Peter Astrand7d1d4362006-07-14 14:04:45 +0000754- Bug #1223937: subprocess.CalledProcessError reports the exit status
755 of the process using the returncode attribute, instead of
756 abusing errno.
757
Tim Peters711bf302006-04-25 03:31:36 +0000758- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
759 a doctest to be skipped (the code is not run, and the expected output
760 or exception is ignored).
761
Nick Coghlanda2268f2006-04-24 04:37:15 +0000762- Fixed contextlib.nested to cope with exceptions being raised and
763 caught inside exit handlers.
764
Greg Wardab05edc2006-04-23 03:47:58 +0000765- Updated optparse module to Optik 1.5.1 (allow numeric constants in
766 hex, octal, or binary; add ``append_const`` action; keep going if
767 gettext cannot be imported; added ``OptionParser.destroy()`` method;
768 added ``epilog`` for better help generation).
769
Tim Peters21fbd572006-04-21 21:18:10 +0000770- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
771 called from a thread spawned as a side effect of importing a module.
772
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000773- The pydoc module now supports documenting packages contained in
774 .zip or .egg files.
775
776- The pkgutil module now has several new utility functions, such
777 as ``walk_packages()`` to support working with packages that are either
778 in the filesystem or zip files.
779
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000780- The mailbox module can now modify and delete messages from
781 mailboxes, in addition to simply reading them. Thanks to Gregory
782 K. Johnson for writing the code, and to the 2005 Google Summer of
783 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000784
Tim Petersc7605f22006-04-17 21:12:33 +0000785- The ``__del__`` method of class ``local`` in module ``_threading_local``
786 returned before accomplishing any of its intended cleanup.
787
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000788- Patch #790710: Add breakpoint command lists in pdb.
789
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000790- Patch #1063914: Add Tkinter.Misc.clipboard_get().
791
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000792- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
793
Anthony Baxtere29002c2006-04-12 12:07:31 +0000794- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
795 Windows. Bug #1469163.
796
Phillip J. Eby47032112006-04-11 01:07:43 +0000797- The warnings, linecache, inspect, traceback, site, and doctest modules
798 were updated to work correctly with modules imported from zipfiles or
799 via other PEP 302 __loader__ objects.
800
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000801- Patch #1467770: Reduce usage of subprocess._active to processes which
802 the application hasn't waited on.
803
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000804- Patch #1462222: Fix Tix.Grid.
805
Neal Norwitza31bf182006-04-09 03:35:43 +0000806- Fix exception when doing glob.glob('anything*/')
807
Skip Montanaro262fb922006-04-21 02:31:07 +0000808- The pstats.Stats class accepts an optional stream keyword argument to
809 direct output to an alternate file-like object.
810
Anthony Baxter51bcb682006-04-05 14:51:42 +0000811Build
812-----
813
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000814- The Makefile now has a reindent target, which runs reindent.py on
815 the library.
816
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000817- Patch #1470875: Building Python with MS Free Compiler
818
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000819- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000820
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000821- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
822 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000823 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000824 CXX from --with-cxx-main, see description in README.
825
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000826- Patch #1429775: Link extension modules with the shared libpython.
827
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000828- Fixed a libffi build problem on MIPS systems.
829
Tim Peters8931ff12006-05-13 23:28:20 +0000830- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
831 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
832 and "%zu" for unsigned integers of type ``size_t``.
833
Anthony Baxter51bcb682006-04-05 14:51:42 +0000834Tests
835-----
836
Nick Coghlanda2268f2006-04-24 04:37:15 +0000837- test_contextlib now checks contextlib.nested can cope with exceptions
838 being raised and caught inside exit handlers.
839
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000840- test_cmd_line now checks operation of the -m and -c command switches
841
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000842- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
843 it separately and by hand. It also wasn't cleaning up its changes to
844 the current Decimal context.
845
Thomas Woutersabd08882006-04-26 15:53:30 +0000846- regrtest.py now has a -M option to run tests that test the new limits of
847 containers, on 64-bit architectures. Running these tests is only sensible
848 on 64-bit machines with more than two gigabytes of memory. The argument
849 passed is the maximum amount of memory for the tests to use.

858-------------
859
Tim Petersb06d28c2006-05-12 01:57:59 +0000860- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
861
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000862- PEP 343: Added Context Types section to the library reference
863 and attempted to bring other PEP 343 related documentation into
864 line with the implementation and/or python-dev discussions.
865
Tim Peters8dc73d22006-04-24 02:03:16 +0000866- Bug #1337990: clarified that ``doctest`` does not support examples
867 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000870What's New in Python 2.5 alpha 1?
871=================================
872
Anthony Baxterebed3f62006-04-03 15:03:44 +0000873*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000874
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000875Core and builtins
876-----------------
877
Nick Coghlan43832302006-04-23 17:04:07 +0000878- PEP 338: -m command line switch now delegates to runpy.run_module
879 allowing it to support modules in packages and zipfiles
880
Martin v. Löwisc661b882006-04-20 04:54:23 +0000881- On Windows, .DLL is not an accepted file name extension for
882 extension modules anymore; extensions are only found if they
883 end in .PYD.
884
Martin v. Löwisea62d252006-04-03 10:56:49 +0000885- Bug #1421664: sys.stderr.encoding is now set to the same value as
886 sys.stdout.encoding.
887
Neal Norwitz92e212f2006-04-03 04:48:37 +0000888- __import__ accepts keyword arguments.
889
Georg Brandlccadf842006-03-31 18:54:53 +0000890- Patch #1460496: round() now accepts keyword arguments.
891
Anthony Baxter262c00a2006-03-30 10:53:17 +0000892- Fixed bug #1459029 - unicode reprs were double-escaped.
893
Hye-Shik Changd478f342006-03-23 12:32:36 +0000894- Patch #1396919: The system scope threads are reenabled on FreeBSD
895 5.4 and later versions.
896
Neal Norwitze98ccf62006-03-23 05:39:47 +0000897- Bug #1115379: Compiling a Unicode string with an encoding declaration
898 now gives a SyntaxError.
899
Georg Brandlabd1ff82006-03-18 07:59:59 +0000900- Previously, Python code had no easy way to access the contents of a
901 cell object. Now, a ``cell_contents`` attribute has been added
902 (closes patch #1170323).
903
Tim Peterscf79aac2006-03-16 01:14:46 +0000904- Patch #1123430: Python's small-object allocator now returns an arena to
905 the system ``free()`` when all memory within an arena becomes unused
906 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
907 freed. Some applications will see a drop in virtual memory size now,
908 especially long-running applications that, from time to time, temporarily
909 use a large number of small objects. Note that when Python returns an
910 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000911 platform C library will in turn return that memory to the operating system.
912 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000913 appears to be effective at least on Microsoft C and gcc-based systems.
914 Thanks to Evan Jones for hard work and patience.
915
Georg Brandl533ff6f2006-03-08 18:09:27 +0000916- Patch #1434038: property() now uses the getter's docstring if there is
917 no "doc" argument given. This makes it possible to legitimately use
918 property() as a decorator to produce a read-only property.
919
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000920- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
921 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
922 of requiring an int or long in slicing and a few other contexts, enabling
923 other objects (e.g. Numeric Python's integers) to be used as slice indices.
924
Neal Norwitz995acdf2006-03-07 05:01:00 +0000925- Fixed various bugs reported by Coverity's Prevent tool.
926
Brett Cannonbf364092006-03-01 04:25:17 +0000927- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
928 new exception base class, BaseException, which has a new message attribute.
929 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
930 Raising a string exception now raises a DeprecationWarning.
931
Thomas Woutersfb609f42006-02-28 16:37:25 +0000932- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
933 explicitly relative, using 'from .module import name' to mean 'from the same
934 package as this module is in. Imports without dots still default to the
935 old relative-then-absolute, unless 'from __future__ import
936 absolute_import' is used.
937
Brett Cannona7446e32006-02-27 23:39:10 +0000938- Properly check if 'warnings' raises an exception (usually when a filter set
939 to "error" is triggered) when raising a warning for raising string
940 exceptions.
941
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000942- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000943 The name was removed from Include/code.h.
944
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000945- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000946
Guido van Rossum1968ad32006-02-25 22:38:04 +0000947- Patch 1433928:
948 - The copy module now "copies" function objects (as atomic objects).
949 - dict.__getitem__ now looks for a __missing__ hook before raising
950 KeyError.
951
Tim Peters84ef21c2006-02-28 20:39:06 +0000952- PEP 343: with statement implemented. Needs ``from __future__ import
953 with_statement``. Use of 'with' as a variable will generate a warning.
954 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000955 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000956 The following objects have __context__ methods:
957 - The built-in file type.
958 - The thread.LockType type.
959 - The following types defined by the threading module:
960 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
961 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000962
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000963- Fix the encodings package codec search function to only search
964 inside its own package. Fixes problem reported in patch #1433198.
965
966 Note: Codec packages should implement and register their own
967 codec search function. PEP 100 has the details.
968
Tim Peters9ea89d22006-06-04 03:26:02 +0000969- PEP 353: Using ``Py_ssize_t`` as the index type.
970
971- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
972 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
973 now allow Python to make use of memory blocks exceeding 2**32 bytes for
974 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
975 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000976
Neal Norwitzfc76d632006-01-10 06:03:13 +0000977- Patch #1400181, fix unicode string formatting to not use the locale.
978 This is how string objects work. u'%f' could use , instead of .
979 for the decimal point. Now both strings and unicode always use periods.
980
Neal Norwitz671b9e32006-01-09 07:07:12 +0000981- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
982 configure would break checking curses.h.
983
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000984- Bug #959576: The pwd module is now builtin. This allows Python to be
985 built on UNIX platforms without $HOME set.
986
Neal Norwitzc10978f2005-12-19 06:07:16 +0000987- Bug #1072182, fix some potential problems if characters are signed.
988
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000989- Bug #889500, fix line number on SyntaxWarning for global declarations.
990
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000991- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
992
Neal Norwitze7214a12005-12-18 05:03:17 +0000993- Support for converting hex strings to floats no longer works.
994 This was not portable. float('0x3') now raises a ValueError.
995
Barry Warsaw2a38a862005-12-18 01:27:35 +0000996- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000997 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000998 is now displayed in interactive prompt banner.
999
Georg Brandlfa166682005-12-17 21:45:17 +00001000- Implementation of PEP 341 - Unification of try/except and try/finally.
1001 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001002 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001003
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001004- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1005 now encodes backslash correctly.
1006
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001007- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1008
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001009- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001010 and long longs.
1011
Neal Norwitz67715f02005-11-09 06:59:35 +00001012- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001013 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001014 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001015
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001016- Replaced most Unicode charmap codecs with new ones using the
1017 new Unicode translate string feature in the builtin charmap
1018 codec; the codecs were created from the mapping tables available
1019 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1020 encodings now include a mapping for the Apple logo)
1021
Tim Peterse3547fd2005-12-16 23:13:57 +00001022- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001023
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001024- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001025
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001026- A new AST parser implementation was completed. The abstract
1027 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001028 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001029
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001030- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001031 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1032
Neal Norwitz708e51a2005-10-03 04:48:15 +00001033- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1034
Neal Norwitz11bd1192005-10-03 00:54:56 +00001035- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1036 Provide a warning when a directory is passed on the command line.
1037
Neal Norwitz40d37812005-10-02 01:48:49 +00001038- Fix segfault with invalid coding.
1039
1040- SF bug #772896: unknown encoding results in MemoryError.
1041
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001042- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001043 supported a __len__() method which evaluated to False when the iterator
1044 was empty.
1045
Guido van Rossum630db602005-09-20 18:49:54 +00001046- On 64-bit platforms, when __len__() returns a value that cannot be
1047 represented as a C int, raise OverflowError.
1048
Skip Montanarof8948ca2005-09-19 03:54:46 +00001049- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001050 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001051
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001052- SF bug #893549: parsing keyword arguments was broken with a few format
1053 codes.
1054
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001055- Changes donated by Elemental Security to make it work on AIX 5.3
1056 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1057 bug #105470: test_pwd fails on 64bit system (Opteron).
1058
Guido van Rossum539c6622005-09-14 17:49:54 +00001059- Changes donated by Elemental Security to make it work on HP-UX 11 on
1060 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1061
Georg Brandl4550b8d2005-08-26 06:43:52 +00001062- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001063 (fixes bug #1119418).
1064
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001065- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1066
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001067- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1068 exceptions that cause a function to exit.
1069
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001070- The implementation of set() and frozenset() was revised to use its
1071 own internal data structure. Memory consumption is reduced by 1/3
1072 and there are modest speed-ups as well. The API is unchanged.
1073
Tim Petersde7990b2005-07-17 23:45:23 +00001074- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1075
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001076- SF bug #1229429: PyObject_CallMethod failed to decrement some
1077 reference counts in some error exit cases.
1078
Tim Petersecc6e6a2005-07-10 22:30:55 +00001079- SF bug #1185883: Python's small-object memory allocator took over
1080 a block managed by the platform C library whenever a realloc specified
1081 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001082 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001083 portable way to copy data from the C-managed block into Python's
1084 small-object space without risking a memory fault. Python's small-object
1085 realloc now leaves such blocks under the control of the platform C
1086 realloc.
1087
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001088- SF bug #1232517: An overflow error was not detected properly when
1089 attempting to convert a large float to an int in os.utime().
1090
Raymond Hettinger3296e692005-06-29 23:29:56 +00001091- SF bug #1224347: hex longs now print with lowercase letters just
1092 like their int counterparts.
1093
Michael W. Hudson188d4362005-06-20 16:52:57 +00001094- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1095 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1096 interpreter states; back out that fix and do a better job (see
1097 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1098 for a longer write-up of the problem).
1099
Michael W. Hudsondf888462005-06-03 14:41:55 +00001100- SF patch #1180995: marshal now uses a binary format by default when
1101 serializing floats.
1102
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001103- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1104 the routines that promise to produce IEEE 754 binary representations
1105 of floats now simply copy bytes around.
1106
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001107- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1108 278.
1109
Brett Cannonc3647ac2005-04-26 03:45:26 +00001110- patch #1109424: int, long, float, complex, and unicode now check for the
1111 proper magic slot for type conversions when subclassed. Previously the
1112 magic slot was ignored during conversion. Semantics now match the way
1113 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001114 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001115 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001116 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001117
Barry Warsawc8d907c2005-04-19 23:43:40 +00001118- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1119 NULL, now raise an AttributeError when attempting to set or delete the
1120 attribute. Previously a TypeError was raised, but this was inconsistent
1121 with the equivalent pure-Python implementation.
1122
Michael W. Hudson774479c2005-04-18 08:46:17 +00001123- It is now safe to call PyGILState_Release() before
1124 PyEval_InitThreads() (note that if there is reason to believe there
1125 are multiple threads around you still must call PyEval_InitThreads()
1126 before using the Python API; this fix is for extension modules that
1127 have no way of knowing if Python is multi-threaded yet).
1128
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001129- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1130 disabled caused a crash.
1131
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001132- Bug #1165306: instancemethod_new allowed the creation of a method
1133 with im_class == im_self == NULL, which caused a crash when called.
1134
Tim Petersecc6e6a2005-07-10 22:30:55 +00001135- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001136 fixes the crash seen in bug #1165761
1137
Raymond Hettinger96229b12005-03-11 06:49:40 +00001138- Added two new builtins, any() and all().
1139
Brett Cannon409d8f22005-03-05 06:47:57 +00001140- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001141 (e.g., ``class C(): pass`` is no longer a syntax error).
1142 Patch #1176012 added support to the 'parser' module and 'compiler' package
1143 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001144
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001145- Patch #1115086: Support PY_LONGLONG in structmember.
1146
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001147- Bug #1155938: new style classes did not check that __init__() was
1148 returning None.
1149
Tim Petersecc6e6a2005-07-10 22:30:55 +00001150- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001151 ('\') with a specific error message.
1152
Martin v. Löwisff232d72005-03-03 09:24:38 +00001153- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1154
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001155- Bug #1124295: the __name__ attribute of file objects was
1156 inadvertently made inaccessible in restricted mode.
1157
Tim Petersecc6e6a2005-07-10 22:30:55 +00001158- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001159 an ferror() call.
1160
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001161- min() and max() now support key= arguments with the same meaning as in
1162 list.sort().
1163
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001164- The peephole optimizer now performs simple constant folding in expressions:
1165 (2+3) --> (5).
1166
Raymond Hettingera422c342005-01-11 03:03:27 +00001167- set and frozenset objects can now be marshalled. SF #1098985.
1168
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001169- Bug #1077106: Poor argument checking could cause memory corruption
1170 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001171
Jeremy Hyltonab630502005-02-04 18:44:06 +00001172- The parser did not complain about future statements in illegal
1173 positions. It once again reports a syntax error if a future
1174 statement occurs after anything other than a doc string.
1175
Neil Schemenauercf52c072005-08-12 17:34:58 +00001176- Change the %s format specifier for str objects so that it returns a
1177 unicode instance if the argument is not an instance of basestring and
1178 calling __str__ on the argument returns a unicode instance.
1179
Tim Petersf4e69282006-02-27 17:15:31 +00001180- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1181 current thread state when the auto-GIL-state machinery knows about
1182 it (since the thread state is being deleted, continuing to remember it
1183 can't help, but can hurt if another thread happens to get created with
1184 the same thread id).
1185
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001186Extension Modules
1187-----------------
1188
Georg Brandl43f08a82006-03-31 18:01:16 +00001189- Patch #1380952: fix SSL objects timing out on consecutive read()s
1190
Neal Norwitz05a45592006-03-20 06:30:08 +00001191- Patch #1309579: wait3 and wait4 were added to the posix module.
1192
Anthony Baxterfa869072006-03-20 05:21:58 +00001193- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1194 In addition, the existing ulaw code was updated.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001376- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1377 been renamed to have only a single underscore prefix. This was done to
1378 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001379
Nick Coghlan43832302006-04-23 17:04:07 +00001380- PEP 338: new module runpy defines a run_module function to support
1381 executing modules which provide access to source code or a code object
1382 via the PEP 302 import mechanisms.
1383
Anthony Baxter93f5b932006-04-03 08:05:07 +00001384- The email module's parsedate_tz function now sets the daylight savings

1392 in attribute values.
1393
Anthony Baxterc51ee692006-04-01 00:57:31 +00001394- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001395 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001396 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001397 module will not be built.
1398
Tim Petersc17976e2006-04-01 00:26:53 +00001399- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1400 aren't officially supported here, and trying to use them will probably
1401 raise an exception some day. But dicts have been allowed, and "mostly
1402 worked", so support for them won't go away without warning.
1403
Georg Brandl338ef7d2006-03-31 18:42:16 +00001404- Bug #1445068: getpass.getpass() can now be given an explicit stream
1405 argument to specify where to write the prompt.
1406

1422
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001423- email 4.0 package now integrated. This is largely the same as the email 3.0
1424 package that was included in Python 2.3, except that PEP 8 module names are
1425 now used (e.g. mail.message instead of email.Message). The MIME classes
1426 have been moved to a subpackage (e.g. email.mime.text instead of
1427 email.MIMEText). The old names are still supported for now. Several
1428 deprecated Message methods have been removed and lots of bugs have been
1429 fixed. More details can be found in the email package documentation.
1430
Walter Dörwald40108c92006-03-27 08:15:44 +00001431- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1432 (a subclass of tuple) that provides incremental decoders and encoders
1433 (a way to use stateful codecs without the stream API). Python functions
1434 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1435 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1436 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001438- Patch #1359365: Calling next() on a closed StringIO.String object raises
1439 a ValueError instead of a StopIteration now (like file and cString.String do).

1517 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1518 Ronald L. Rivest offered this advice for Python:
1519
1520 "The consensus of researchers in this area (at least as
1521 expressed at the NIST Hash Function Workshop 10/31/05),
1522 is that SHA-256 is a good choice for the time being, but
1523 that research should continue, and other alternatives may
1524 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001525

1706 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001707 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001708 PEP 305.

1712 dictates.
1713 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001714 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001715 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001716 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1717 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001718 + reader now allows \r characters to be quoted (previously it only allowed
1719 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001720 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001721 + Dialect classes passed to the module are no longer instantiated by
1722 the module before being parsed (the former validation scheme required
1723 this, but the mechanism was unreliable).
1724 + The dialect registry now contains instances of the internal
1725 C-coded dialect type, rather than references to python objects.
1726 + the internal c-coded dialect type is now immutable.
1727 + register_dialect now accepts the same keyword dialect specifications
1728 as the reader and writer, allowing the user to register dialects
1729 without first creating a dialect class.
1730 + a configurable limit to the size of parsed fields has been added -
1731 previously, an unmatched quote character could result in the entire
1732 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001733 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001734 the parser field size limit (returning the former limit). The initial
1735 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001736 + A line_num attribute has been added to the reader object, which tracks
1737 the number of lines read from the source iterator. This is not
1738 the same as the number of records returned, as records can span
1739 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001740 + reader and writer objects were not being registered with the cyclic-GC.
1741 This has been fixed.
1742
Brett Cannone6539c42005-01-08 02:43:53 +00001743- _DummyThread objects in the threading module now delete self.__block that is
1744 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1745 lock primitives tend to be limited in number and thus should not be wasted on
1746 a _DummyThread object. Fixes bug #1089632.
1747
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001748- The imghdr module now detects Exif files.
1749
Raymond Hettinger6065d322004-12-20 23:51:53 +00001750- StringIO.truncate() now correctly adjusts the size attribute.
1751 (Bug #951915).
1752
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001753- locale.py now uses an updated locale alias table (built using
1754 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1755 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001756 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001757
Raymond Hettinger3557f422004-12-07 12:02:02 +00001758- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1759
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001760- the pickle module no longer accepts the deprecated None option in the
1761 args tuple returned by __reduce__().
1762
Brett Cannon84667c02004-12-07 03:25:18 +00001763- optparse now optionally imports gettext. This allows its use in setup.py.
1764
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001765- the pickle module no longer uses the deprecated bin parameter.
1766
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001767- the shelve module no longer uses the deprecated binary parameter.
1768

1770
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001771- the filecmp module no longer uses the deprecated use_statcache argument.
1772
Raymond Hettinger664347b2004-12-04 21:21:53 +00001773- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1774 extended or overridden by subclasses. Formerly, the subclassed method would
1775 be ignored by the rest of the module. (Bug #1078905).
1776
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001777- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001778 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001779
Walter Dörwald36733692004-12-22 12:50:50 +00001780- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1781 once when a size argument is given. This prevents a buffer overflow in the
1782 tokenizer with very long source lines.
1783
Barry Warsaw538561e2006-01-01 21:48:54 +00001784- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1785 immediately after creating the object, without any intervening
1786 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001787
Skip Montanaro05885812005-01-16 20:48:27 +00001788- The reconvert.quote function can now emit triple-quoted strings. The
1789 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001790
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001791- ``UserString.MutableString`` now supports negative indices in
1792 ``__setitem__`` and ``__delitem__``
1793
Greg Ward40407942005-03-05 02:53:17 +00001794- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1795 correctly.
1796
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001797- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1798 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1799 character even if the user has passed a size parameter to get a proper
1800 line ending. Remove the special handling of a "\r\n" that has been split
1801 between two lines.
1802
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001803- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1804 about illegal code points. The codec now supports PEP 293 style error
1805 handlers.
1806
Walter Dörwald78a78b02005-09-01 12:04:29 +00001807- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001808 from the input stream, so that the output is a byte string in the correct
1809 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001810
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001811- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1812 considering it exactly like a '*'.
1813
Walter Dörwald007f8df2005-10-09 19:42:27 +00001814- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1815 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001816
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001817- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1818
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001819- Patch #1413711: Certain patterns of differences were making difflib
1820 touch the recursion limit.
1821
Walter Dörwald58917a62006-03-31 15:26:22 +00001822- Bug #947906: An object oriented interface has been added to the calendar
1823 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001824 called as a script (e.g. via ``python -mcalendar``). Localized month and
1825 weekday names can be ouput (even if an exotic encoding is used) using
1826 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001827
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001828Build
1829-----
1830
Neal Norwitz602d3392006-03-31 08:21:40 +00001831- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1832 by using -mieee gcc option.
1833
Martin v. Löwis86d66262006-02-17 08:40:11 +00001834- Patch #1432345: Make python compile on DragonFly.
1835
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001836- Build support for Win64-AMD64 was added.
1837
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001838- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1839
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001840- Patch #881820: look for openpty and forkpty also in libbsd.
1841
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001842- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1843 The zlib module is now builtin on Windows.
1844
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001845- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1846
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001847- Bug #1189330: configure did not correctly determine the necessary
1848 value of LINKCC if python was built with GCC 4.0.
1849
Trent Mick8321b422005-07-26 02:29:21 +00001850- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1851 vulnerability in zlib 1.2.1 and 1.2.2.
1852
Brett Cannon08cd5982005-04-24 22:26:38 +00001853- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1854 flags that change binary compatibility. Changes were also made to
1855 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001856 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001857
Bob Ippolitoed233462005-03-29 13:47:59 +00001858- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1859 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1860 no longer exists). This configure patch makes things right.
1861
Martin v. Löwise2713be2005-03-08 15:03:08 +00001862- Bug #1158607: Build with --disable-unicode again.
1863
Brett Cannon46d96232005-02-16 00:07:19 +00001864- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1865 defined. Discovered as a result of not being able to build on OS X.
1866
Brett Cannon516592f2004-12-07 00:42:59 +00001867- setup.py now uses the directories specified in LDFLAGS using the -L option
1868 and in CPPFLAGS using the -I option for adding library and include
1869 directories, respectively, for compiling extension modules against. This has
1870 led to the core being compiled using the values in CPPFLAGS. It also removes
1871 the need for the special-casing of both DarwinPorts and Fink for darwin since
1872 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1873 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1874 Fink, ``-I/opt/local/include`` for DarwinPorts).
1875
Brett Cannon43802422005-02-10 20:48:03 +00001876- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1877 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1878 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1879 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001881C API
1882-----
1883
Tim Petersc9d78aa2006-03-26 23:27:58 +00001884- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1885 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1886 is obtained via the ``PyObject_`` family, it must be released via the
1887 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1888 always been officially true, but when Python's small-object allocator was
1889 introduced, an attempt was made to cater to a few extension modules
1890 discovered at the time that obtained memory via ``PyObject_New`` but
1891 released it via ``PyMem_DEL``. It's years later, and if such code still
1892 exists it will fail now (probably with segfaults, but calling wrong
1893 low-level memory management functions can yield many symptoms).
1894
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001895- Added a C API for set and frozenset objects.
1896
Raymond Hettinger66517482004-12-03 11:45:13 +00001897- Removed PyRange_New().
1898
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001899- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1900 mapping argument now. This string is used as a mapping table. Byte values
1901 greater than the length of the string and 0xFFFE are treated as undefined
1902 mappings.
