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
Georg Brandl07fec3a2006-08-01 18:49:24 +000067- os.urandom no longer masks unrelated exceptions like SystemExit or
68 KeyboardInterrupt.
69
Martin v. Löwis4e678382006-07-30 13:00:31 +000070- Bug #1525866: Don't copy directory stat times in
71 shutil.copytree on Windows
72
Georg Brandle34ac7c2006-07-30 11:07:23 +000073- Bug #1002398: The documentation for os.path.sameopenfile now correctly
74 refers to file descriptors, not file objects.
75
Fred Drakefbdeaad2006-07-29 16:56:15 +000076- Rename of the xml package to xmlcore, and the import hackery done to
77 make it appear at both names, has been removed. Bug #1511497,
78 #1513611, and probably others.
79
Georg Brandledd9b0d2006-07-29 09:33:26 +000080- Bug #1441397: The compiler module now recognizes module and function
81 docstrings correctly as it did in Python 2.4.
82
Tim Peters6f681472006-07-27 23:44:37 +000083- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
84 lost that tests are sorted by name before being run. This rarely
85 matters for well-written tests, but can create baffling symptoms if
86 side effects from one test to the next affect outcomes. ``DocTestFinder``
87 has been changed to sort the list of tests it returns.
88
Martin v. Löwis1f30c372006-07-30 13:14:05 +000089- The distutils version has been changed to 2.5.0, and are now kept
90 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +000091
Martin v. Löwis9298eff2006-07-26 12:12:56 +000092- Bug #978833: Really close underlying socket in _socketobject.close.
93
Georg Brandl0619a322006-07-26 07:40:17 +000094- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
95 with title().
96
Georg Brandlcf0c1722006-07-26 07:23:32 +000097- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
98 to recursive calls and call it with the failing package name.
99
Martin v. Löwis0b483032006-07-25 09:53:12 +0000100- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
101
Georg Brandlc13c34c2006-07-24 14:09:56 +0000102- Patch #1515343: Fix printing of deprecated string exceptions with a
103 value in the traceback module.
104
Greg Ward48fae7a2006-07-23 16:05:51 +0000105- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
106
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000107- Patch #1524429: Use repr() instead of backticks in Tkinter again.
108
Brett Cannoncaebe222006-07-18 04:41:36 +0000109- Bug #1520914: Change time.strftime() to accept a zero for any position in its
110 argument tuple. For arguments where zero is illegal, the value is forced to
111 the minimum value that is correct. This is to support an undocumented but
112 common way people used to fill in inconsequential information in the time
113 tuple pre-2.4.
114
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000115- Patch #1220874: Update the binhex module for Mach-O.
116
Barry Warsawb110bad2006-07-21 14:51:07 +0000117- The email package has improved RFC 2231 support, specifically for
118 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
119 (name*0=<blah>) parameter continuations. This may change the types of
120 values returned from email.message.Message.get_param() and friends.
121 Specifically in some cases where non-encoded continuations were used,
122 get_param() used to return a 3-tuple of (None, None, string) whereas now it
123 will just return the string (since non-encoded continuations don't have
124 charset and language parts).
125
126 Also, whereas % values were decoded in all parameter continuations, they are
127 now only decoded in encoded parameter parts.
128
Ronald Oussoren3075e162006-07-25 20:28:55 +0000129- Bug #1517990: IDLE keybindings on MacOS X now work correctly
130
131- Bug #1517996: IDLE now longer shows the default Tk menu when a
132 path browser, class browser or debugger is the frontmost window on MacOS X
133
Barry Warsaw00decd72006-07-27 23:43:15 +0000134- Patch #1520294: Support for getset and member descriptors in types.py,
135 inspect.py, and pydoc.py. Specifically, this allows for querying the type
136 of an object against these built-in types and more importantly, for getting
137 their docstrings printed in the interactive interpreter's help() function.
138
Ronald Oussoren3075e162006-07-25 20:28:55 +0000139
Neal Norwitza1f10902006-07-12 07:28:29 +0000140Extension Modules
141-----------------
142
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000143- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
144 a socket operation on a socket with a timeout, the exception will be
145 caught correctly. Previously, the exception was not caught.
146
Thomas Heller1393d6a2006-07-28 21:43:20 +0000147- Patch #1529514: The _ctypes extension is now compiled on more
148 openbsd target platforms.
149
Tim Peters9cab5932006-07-28 00:30:00 +0000150- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
151 a memory leak, affecting pickles and deep copies.
152
Tim Petersbc24eee2006-07-27 01:14:53 +0000153- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000154 Paul Eggert.
155
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000156- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
157
Thomas Hellerce049a02006-07-14 17:51:14 +0000158- Patch #1521817: Index range checking on ctypes arrays containing
159 exactly one element enabled again. This allows iterating over these
160 arrays, without the need to check the array size before.
161
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000162- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000163 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000164 /dev/null in certain cases; this is now fixed.
165
Thomas Heller47d7a062006-07-12 08:43:47 +0000166- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
167 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000168
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000169- Because of a misspelled preprocessor symbol, ctypes was always
170 compiled without thread support; this is now fixed.
171
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000172- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
173 methods now allow their database parameter to be None as the
174 sleepycat API allows.
175
Matt Flemingec926502006-07-28 11:27:27 +0000176- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
177 bluetooth API compared with Linux and FreeBSD.
178
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000179Tests
180-----
181
182- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
183 how long the test file should take to play. Now accepts taking 2.93 secs
184 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
185
Georg Brandl4793aa32006-07-28 18:31:39 +0000186- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
187 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
188 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000189
Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000190Build
191-----
192
193- Bug #1439538: Drop usage of test -e in configure as it is not portable.
194
Ronald Oussoren26cad082006-08-01 21:00:57 +0000195Mac
196---
197
198- PythonLauncher now works correctly when the path to the script contains
199 characters that are treated specially by the shell (such as quotes).
200
201- Bug #1527397: PythonLauncher now launches scripts with the working directory
202 set to the directory that contains the script instead of the user home
203 directory. That latter was an implementation accident and not what users
204 expect.
205
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000206
Georg Brandlad29e632006-06-21 17:45:17 +0000207What's New in Python 2.5 beta 2?

Georg Brandlad29e632006-06-21 17:45:17 +0000211
212Core and builtins
213-----------------
214
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000215- Bug #1441486: The literal representation of -(sys.maxint - 1)
216 again evaluates to a int object, not a long.
217
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000218- Bug #1501934: The scope of global variables that are locally assigned
219 using augmented assignment is now correctly determined.
220
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000221- Bug #927248: Recursive method-wrapper objects can now safely
222 be released.
223
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000224- Bug #1417699: Reject locale-specific decimal point in float()
225 and atof().
226
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000227- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
228 omit a default "error" argument for NULL pointer. This allows
229 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000230
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000231- Bug #1519018: 'as' is now validated properly in import statements.
232
Neal Norwitz28746ab2006-07-09 22:14:42 +0000233- On 64 bit systems, int literals that use less than 64 bits are
234 now ints rather than longs.
235
Neal Norwitzed657552006-07-10 00:04:44 +0000236- Bug #1512814, Fix incorrect lineno's when code at module scope
237 started after line 256.
238
Tim Peters32a83612006-07-10 21:08:24 +0000239- New function ``sys._current_frames()`` returns a dict mapping thread
240 id to topmost thread stack frame. This is for expert use, and is
241 especially useful for debugging application deadlocks. The functionality
242 was previously available in Fazal Majid's ``threadframe`` extension
243 module, but it wasn't possible to do this in a wholly threadsafe way from
244 an extension.
245

Tim Peters32a83612006-07-10 21:08:24 +0000254- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000255 environment variable to be set in order to the SDK environment
256 for finding the compiler, include files, etc.
257
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000258- Bug #1515998: Properly generate logical ids for files in bdist_msi.

Nick Coghlan2d792252006-07-06 13:47:18 +0000260- warnings.py now ignores ImportWarning by default
261
Thomas Woutersadd19112006-07-05 11:03:49 +0000262- string.Template() now correctly handles tuple-values. Previously,
263 multi-value tuples would raise an exception and single-value tuples would
264 be treated as the value they contain, instead.
265
Martin v. Löwisede77f52006-07-03 13:01:35 +0000266- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

273 degrees and radians.
274
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000275- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000276 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000277
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000278- Bug #1514703: Only setup canvas window in turtle when the canvas
279 is created.
280
Martin v. Löwis7596e832006-07-01 15:33:37 +0000281- Bug #1513223: .close() of a _socketobj now releases the underlying
282 socket again, which then gets closed as it becomes unreferenced.
283
Fred Drake10497c82006-06-29 02:57:48 +0000284- Bug #1504333: Make sgmllib support angle brackets in quoted
285 attribute values.
286
287- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
288 sgmllib ('[' and ']' were not accepted).
289
Georg Brandl1be63af2006-06-28 20:23:25 +0000290- Fix a bug in the turtle module's end_fill function.
291
Brett Cannon53ab5b72006-06-22 16:49:14 +0000292- Bug #1510580: The 'warnings' module improperly required that a Warning
293 category be either a types.ClassType and a subclass of Warning. The proper
294 check is just that it is a subclass with Warning as the documentation states.
295
Georg Brandlad29e632006-06-21 17:45:17 +0000296- The compiler module now correctly compiles the new try-except-finally
297 statement (bug #1509132).
298
Neal Norwitz60373cd2006-06-22 06:30:50 +0000299- The wsgiref package is now installed properly on Unix.
300
Vinay Sajip28e57612006-07-01 10:45:20 +0000301- A bug was fixed in logging.config.fileConfig() which caused a crash on
302 shutdown when fileConfig() was called multiple times.
303
Gerhard Häring762fbd32006-07-02 17:48:30 +0000304- The sqlite3 module did cut off data from the SQLite database at the first
305 null character before sending it to a custom converter. This has been fixed
306 now.

Tim Peters112aad32006-07-19 00:03:19 +0000311- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
312 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
313 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000314
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000315- Assigning None to pointer type fields in ctypes structures possible
316 overwrote the wrong fields, this is fixed now.
317
318- Fixed a segfault in _ctypes when ctypes.wintypes were imported
319 on non-Windows platforms.
320
321- Bug #1518190: The ctypes.c_void_p constructor now accepts any
322 integer or long, without range checking.
323
324- Patch #1517790: It is now possible to use custom objects in the ctypes
325 foreign function argtypes sequence as long as they provide a from_param
326 method, no longer is it required that the object is a ctypes type.
327
328- The '_ctypes' extension module now works when Python is configured
329 with the --without-threads option.
330
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000331- Bug #1513646: os.access on Windows now correctly determines write
332 access, again.
333
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000334- Bug #1512695: cPickle.loads could crash if it was interrupted with
335 a KeyboardInterrupt.
336
Neal Norwitza12aa882006-07-06 06:45:08 +0000337- Bug #1296433: parsing XML with a non-default encoding and
338 a CharacterDataHandler could crash the interpreter in pyexpat.
339
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000340- Patch #1516912: improve Modules support for OpenVMS.

343-----
344
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000345- Automate Windows build process for the Win64 SSL module.
346
Tim Peters32a83612006-07-10 21:08:24 +0000347- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000348 Previously, the slight difference could cause compilation errors of the
349 'zlib' module on systems with more than one version of zlib.
350
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000351- The MSI compileall step was fixed to also support a TARGETDIR
352 with spaces in it.
353
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000354- Bug #1517388: sqlite3.dll is now installed on Windows independent
355 of Tcl/Tk.
356
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000357- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000358 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +0000360Tests
361-----
362
363- Call os.waitpid() at the end of tests that spawn child processes in order
364 to minimize resources (zombies).
365
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000366Documentation
367-------------
368
Nick Coghlan2d792252006-07-06 13:47:18 +0000369- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
370 documentation for the warnings module.
371
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000372- Patch #1509163: MS Toolkit Compiler no longer available.
373
Neal Norwitz56640df2006-07-10 02:36:41 +0000374- Patch #1504046: Add documentation for xml.etree.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000378
Anthony Baxterd1136802006-06-19 12:04:15 +0000379*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000380
381Core and builtins
382-----------------
383
Georg Brandla56b9152006-06-19 06:35:54 +0000384- Patch #1507676: Error messages returned by invalid abstract object operations
385 (such as iterating over an integer) have been improved and now include the
386 type of the offending object to help with debugging.
387
Brett Cannonea3912b2006-06-13 21:46:41 +0000388- Bug #992017: A classic class that defined a __coerce__() method that returned
389 its arguments swapped would infinitely recurse and segfault the interpreter.
390
Neal Norwitz909eb122006-06-12 02:13:21 +0000391- Fix the socket tests so they can be run concurrently.
392
Neal Norwitzb9845e72006-06-12 02:11:18 +0000393- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000394 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000395
Brett Cannon22565aa2006-06-09 22:31:23 +0000396- Bug #532646: object.__call__() will continue looking for the __call__
397 attribute on objects until one without one is found. This leads to recursion
398 when you take a class and set its __call__ attribute to an instance of the
399 class. Originally fixed for classic classes, but this fix is for new-style.
400 Removes the infinite_rec_3 crasher.
401
Georg Brandl24250812006-06-09 18:45:48 +0000402- The string and unicode methods startswith() and endswith() now accept
403 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
404
Brett Cannonde3b0522006-06-08 17:00:45 +0000405- Buffer objects, at the C level, never used the char buffer
406 implementation even when the char buffer for the wrapped object was
407 explicitly requested (originally returned the read or write buffer).
408 Now a TypeError is raised if the char buffer is not present but is
409 requested.
410
Georg Brandlddbaa662006-06-04 21:56:52 +0000411- Patch #1346214: Statements like "if 0: suite" are now again optimized
412 away like they were in Python 2.4.
413
Georg Brandlb7c8f542006-05-27 12:30:25 +0000414- Builtin exceptions are now full-blown new-style classes instead of
415 instances pretending to be classes, which speeds up exception handling
416 by about 80% in comparison to 2.5a2.
417
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000418- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
419 Unicode 4.1.
420
Georg Brandlf4ef1162006-05-26 18:03:31 +0000421- Patch #921466: sys.path_importer_cache is now used to cache valid and
422 invalid file paths for the built-in import machinery which leads to
423 fewer open calls on startup.
424
Tim Peters696cf432006-05-24 21:10:40 +0000425- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
426 of-2 bases. The largest speedup is for inputs with about 1000 decimal
427 digits. Conversion from non-power-of-2 bases remains quadratic-time in
428 the number of input digits (it was and remains linear-time for bases
429 2, 4, 8, 16 and 32).
430
Tim Petersb713ec22006-05-23 18:45:30 +0000431- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
432 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
433 an integer close to ``sys.maxint``. This was repaired by patch
434 #1335972, which also gives a nice speedup.
435
Richard Jonescebbefc2006-05-23 18:28:17 +0000436- Patch #1337051: reduced size of frame objects.
437
438- PyErr_NewException now accepts a tuple of base classes as its
439 "base" parameter.
440
Richard Jones7c88dcc2006-05-23 10:37:38 +0000441- Patch #876206: function call speedup by retaining allocated frame
442 objects.
443
Georg Brandl7b90e162006-05-18 07:01:27 +0000444- Bug #1462152: file() now checks more thoroughly for invalid mode
445 strings and removes a possible "U" before passing the mode to the
446 C library function.
447
Neal Norwitz1004a532006-05-15 07:17:23 +0000448- Patch #1488312, Fix memory alignment problem on SPARC in unicode
449
Neal Norwitz373f0a72006-05-15 07:04:36 +0000450- Bug #1487966: Fix SystemError with conditional expression in assignment
451
Martin v. Löwis879768d2006-05-11 13:28:43 +0000452- WindowsError now has two error code attributes: errno, which carries
453 the error values from errno.h, and winerror, which carries the error
454 values from winerror.h. Previous versions put the winerror.h values
455 (from GetLastError()) into the errno attribute.
456
Martin v. Löwis77736712006-05-04 05:51:03 +0000457- Patch #1475845: Raise IndentationError for unexpected indent.
458
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000459- Patch #1479181: split open() and file() from being aliases for each other.
460
Tim Peters44bd9862006-06-01 13:49:23 +0000461- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
462 methods were always silently ignored by dictionaries when comparing keys.
463 They are now passed through (except when using the C API function
464 ``PyDict_GetItem()``, whose semantics did not change).
465
466- Bug #1456209: In some obscure cases it was possible for a class with a
467 custom ``__eq__()`` method to confuse dict internals when class instances
468 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
469 No, you don't have any code that did this ;-)

475
476- Patch #1462338: Upgrade pyexpat to expat 2.0.0
477
Brett Cannon6ee7d012006-06-08 16:23:04 +0000478- Change binascii.hexlify to accept a read-only buffer instead of only a char
479 buffer and actually follow its documentation.
480
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000481- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
482
Nick Coghlanc649ec52006-05-29 12:43:05 +0000483- Patch #1478788 (modified version): The functional extension module has
484 been renamed to _functools and a functools Python wrapper module added.
485 This provides a home for additional function related utilities that are
486 not specifically about functional programming. See PEP 309.
487
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000488- Patch #1493701: performance enhancements for struct module.
489
Georg Brandl378d5922006-05-17 14:26:50 +0000490- Patch #1490224: time.altzone is now set correctly on Cygwin.
491
Georg Brandl8d3342b2006-05-16 07:38:27 +0000492- Patch #1435422: zlib's compress and decompress objects now have a
493 copy() method.
494
Andrew MacIntyre92913322006-06-13 15:04:24 +0000495- Patch #1454481: thread stack size is now tunable at runtime for thread
496 enabled builds on Windows and systems with Posix threads support.
497
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000498- On Win32, os.listdir now supports arbitrarily-long Unicode path names
499 (up to the system limit of 32K characters).
500
501- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
502 As a result, these functions now raise WindowsError instead of OSError.
503
Tim Peters7a822da2006-05-25 21:50:17 +0000504- ``time.clock()`` on Win64 should use the high-performance Windows
505 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
506 Windows platforms).
507
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000508- Calling Tk_Init twice is refused if the first call failed as that
509 may deadlock.
510
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000511- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
512 accept it without potentially using an uninitialized pointer.
513
514- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
515 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
516 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000517
Gregory P. Smith372b5832006-06-05 18:48:21 +0000518- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000519 [pybsddb project SF patch number 1466734]
520
Gregory P. Smith372b5832006-06-05 18:48:21 +0000521- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
522 parameter is supplied. [SF pybsddb bug #1477863]
523
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000524- bsddb: the __len__ method of a DB object has been fixed to return correct
525 results. It could previously incorrectly return 0 in some cases.
526 Fixes SF bug 1493322 (pybsddb bug 1184012).
527
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000528- bsddb: the bsddb.dbtables Modify method now raises the proper error and
529 aborts the db transaction safely when a modifier callback fails.
530 Fixes SF python patch/bug #1408584.
531
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000532- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000533 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000534 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
535 database calls that would previously deadlock. [SF python bug #775414]
536
Vinay Sajip28e57612006-07-01 10:45:20 +0000537- Patch #1446489: add support for the ZIP64 extensions to zipfile.

540 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000541
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000542Library
543-------
544
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000545- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
546 functions.
547
Martin v. Löwis3798da02006-06-17 18:44:27 +0000548- Patch #812986: Update turtle output even if not tracing.
549
Vinay Sajip28e57612006-07-01 10:45:20 +0000550- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000551 Tkinter.BaseWidget.
552
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000553- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
554
Martin v. Löwis337487e2006-06-17 09:15:14 +0000555- Patch #763580: Add name and value arguments to Tkinter variable
556 classes.
557
Georg Brandl83cc0d02006-06-14 08:50:03 +0000558- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
559 mime.types file for determining MIME types.
560
Georg Brandl2605ca82006-06-14 06:08:31 +0000561- Bug #1339007: Shelf objects now don't raise an exception in their
562 __del__ method when initialization failed.
563
Martin v. Löwisd8251432006-06-14 05:21:04 +0000564- Patch #1455898: The MBCS codec now supports the incremental mode for
565 double-byte encodings.
566
Tim Peters43898b42006-06-14 04:09:25 +0000567- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
568 guarantee that adjacent triples in the return list always describe
569 non-adjacent blocks. Previously, a pair of matching blocks could end
570 up being described by multiple adjacent triples that formed a partition
571 of the matching pair.
572
Greg Ward0e0c9f42006-06-11 16:24:11 +0000573- Bug #1498146: fix optparse to handle Unicode strings in option help,
574 description, and epilog.
575
Greg Wardd1c797e2006-06-11 14:42:41 +0000576- Bug #1366250: minor optparse documentation error.
577
Greg Ward7f547402006-06-11 00:40:49 +0000578- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
579 clarify docs.
580
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000581- The wsgiref package has been added to the standard library.
582
Nick Coghlan676725d2006-06-08 13:54:49 +0000583- The functions update_wrapper() and wraps() have been added to the functools
584 module. These make it easier to copy relevant metadata from the original
585 function when writing wrapper functions.
586
Tim Petersd6a9eef2006-06-05 01:48:21 +0000587- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
588 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000589
Martin v. Löwis3f767792006-06-04 19:36:28 +0000590- Patch #1359618: Speed up charmap encoder by using a trie structure
591 for lookup.
592
Tim Petersd609b1a2006-06-02 23:22:51 +0000593- The functions in the ``pprint`` module now sort dictionaries by key
594 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
595 if and only if its display required more than one line, although that
596 wasn't documented. The new behavior increases predictability; e.g.,
597 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
598
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000599- Patch #1497027: try HTTP digest auth before basic auth in urllib2
600 (thanks for J. J. Lee).
601
Georg Brandl2b330372006-05-28 20:23:12 +0000602- Patch #1496206: improve urllib2 handling of passwords with respect to
603 default HTTP and HTTPS ports.
604
George Yoshidaf3c65de2006-05-28 16:39:09 +0000605- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
606
Bob Ippolito7298f272006-05-23 18:43:47 +0000607- Patch #1281707: speed up gzip.readline.

Georg Brandlb89316f2006-05-17 15:51:16 +0000609- Patch #1180296: Two new functions were added to the locale module:
610 format_string() to get the effect of "format % items" but locale-aware,
611 and currency() to format a monetary number with currency sign.
612
Georg Brandle3a25832006-05-17 14:56:04 +0000613- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
614 and several features added, such as speed and geometry control.
615
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000616- Patch #1488881: add support for external file objects in bz2 compressed
617 tarfiles.
618
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000619- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
620 stdout arguments, making it possible to redirect input and output
621 for remote debugging.
622
623- Patch #1484695: Update the tarfile module to version 0.8. This fixes
624 a couple of issues, notably handling of long file names using the
625 GNU LONGNAME extension.
626
627- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
628 new flag when ``name`` is already the name of an option flag.
629
630- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
631 package.
632
633- Patch #1472854: make the rlcompleter.Completer class usable on non-
634 UNIX platforms.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000669What's New in Python 2.5 alpha 2?
670=================================
671
672*Release date: 27-APR-2006*
673
674Core and builtins
675-----------------
676
Thomas Heller1b046642006-04-18 18:51:06 +0000677- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
678 by converting these apis from macros into exported functions again:
679
680 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
681 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
682 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
683 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
684 PyRun_String Py_CompileString
685
Martin v. Löwis45294a92006-04-18 06:24:08 +0000686- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
687
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000688- All uses of PyStructSequence_InitType have been changed to initialize
689 the type objects only once, even if the interpreter is initialized
690 multiple times.
691
Neal Norwitz61546162006-04-14 05:20:28 +0000692- Bug #1454485, array.array('u') could crash the interpreter. This was
693 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
694 to unicode when it didn't make sense. 'u#' now requires a unicode string.
695
696- Py_UNICODE is unsigned. It was always documented as unsigned, but
697 due to a bug had a signed value in previous versions.
698
Tim Peters3a5e8b12006-04-11 01:44:07 +0000699- Patch #837242: ``id()`` of any Python object always gives a positive
700 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
701 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000702 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000703 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000704
Tim Peters3a5e8b12006-04-11 01:44:07 +0000705 def __hash__(self):
706 return id(self) # WRONG
707
708 because a hash result must be a (short) Python int but it was always
709 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000710 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000711 was always usable as a hash value before this patch. That's no longer
712 necessarily so.
713
714- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000715 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000716 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000717 #1454844)
718
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000719- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
720 involving generators that have paused outside of any ``try`` or ``with``
721 blocks. (In 2.5a1, a paused generator that was part of a reference
722 cycle could not be garbage collected, regardless of whether it was
723 paused in a ``try`` or ``with`` block.)

729 is a macro.
730
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000731- Bug #1467952: os.listdir() now correctly raises an error if readdir()
732 fails with an error condition.
733
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000734- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
735
736- Bug #1117761: bsddb.*open() no longer raises an exception when using
737 the cachesize parameter.
738
739- Bug #1149413: bsddb.*open() no longer raises an exception when using
740 a temporary db (file=None) with the 'n' flag to truncate on open.
741
742- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
743 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000744
Armin Rigoa9017c32006-04-19 11:50:27 +0000745- Patch #1062014: AF_UNIX sockets under Linux have a special
746 abstract namespace that is now fully supported.
747
Anthony Baxter51bcb682006-04-05 14:51:42 +0000748Library
749-------
750
Peter Astrand7d1d4362006-07-14 14:04:45 +0000751- Bug #1223937: subprocess.CalledProcessError reports the exit status
752 of the process using the returncode attribute, instead of
753 abusing errno.
754
Tim Peters711bf302006-04-25 03:31:36 +0000755- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
756 a doctest to be skipped (the code is not run, and the expected output
757 or exception is ignored).
758
Nick Coghlanda2268f2006-04-24 04:37:15 +0000759- Fixed contextlib.nested to cope with exceptions being raised and
760 caught inside exit handlers.
761
Greg Wardab05edc2006-04-23 03:47:58 +0000762- Updated optparse module to Optik 1.5.1 (allow numeric constants in
763 hex, octal, or binary; add ``append_const`` action; keep going if
764 gettext cannot be imported; added ``OptionParser.destroy()`` method;
765 added ``epilog`` for better help generation).
766
Tim Peters21fbd572006-04-21 21:18:10 +0000767- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
768 called from a thread spawned as a side effect of importing a module.
769
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000770- The pydoc module now supports documenting packages contained in
771 .zip or .egg files.
772
773- The pkgutil module now has several new utility functions, such
774 as ``walk_packages()`` to support working with packages that are either
775 in the filesystem or zip files.
776
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000777- The mailbox module can now modify and delete messages from
778 mailboxes, in addition to simply reading them. Thanks to Gregory
779 K. Johnson for writing the code, and to the 2005 Google Summer of
780 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000781
Tim Petersc7605f22006-04-17 21:12:33 +0000782- The ``__del__`` method of class ``local`` in module ``_threading_local``
783 returned before accomplishing any of its intended cleanup.
784
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000785- Patch #790710: Add breakpoint command lists in pdb.
786
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000787- Patch #1063914: Add Tkinter.Misc.clipboard_get().
788
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000789- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
790
Anthony Baxtere29002c2006-04-12 12:07:31 +0000791- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
792 Windows. Bug #1469163.
793
Phillip J. Eby47032112006-04-11 01:07:43 +0000794- The warnings, linecache, inspect, traceback, site, and doctest modules
795 were updated to work correctly with modules imported from zipfiles or
796 via other PEP 302 __loader__ objects.
797
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000798- Patch #1467770: Reduce usage of subprocess._active to processes which
799 the application hasn't waited on.
800
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000801- Patch #1462222: Fix Tix.Grid.
802
Neal Norwitza31bf182006-04-09 03:35:43 +0000803- Fix exception when doing glob.glob('anything*/')
804
Skip Montanaro262fb922006-04-21 02:31:07 +0000805- The pstats.Stats class accepts an optional stream keyword argument to
806 direct output to an alternate file-like object.
807

809-----
810
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000811- The Makefile now has a reindent target, which runs reindent.py on
812 the library.
813
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000814- Patch #1470875: Building Python with MS Free Compiler
815
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000816- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000817
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000818- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
819 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000820 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000821 CXX from --with-cxx-main, see description in README.
822
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000823- Patch #1429775: Link extension modules with the shared libpython.
824
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000825- Fixed a libffi build problem on MIPS systems.
826
Tim Peters8931ff12006-05-13 23:28:20 +0000827- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
828 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
829 and "%zu" for unsigned integers of type ``size_t``.
830
Anthony Baxter51bcb682006-04-05 14:51:42 +0000831Tests
832-----
833
Nick Coghlanda2268f2006-04-24 04:37:15 +0000834- test_contextlib now checks contextlib.nested can cope with exceptions
835 being raised and caught inside exit handlers.
836
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000837- test_cmd_line now checks operation of the -m and -c command switches
838
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000839- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
840 it separately and by hand. It also wasn't cleaning up its changes to
841 the current Decimal context.
842
Thomas Woutersabd08882006-04-26 15:53:30 +0000843- regrtest.py now has a -M option to run tests that test the new limits of
844 containers, on 64-bit architectures. Running these tests is only sensible
845 on 64-bit machines with more than two gigabytes of memory. The argument
846 passed is the maximum amount of memory for the tests to use.

855-------------
856
Tim Petersb06d28c2006-05-12 01:57:59 +0000857- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
858
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000859- PEP 343: Added Context Types section to the library reference
860 and attempted to bring other PEP 343 related documentation into
861 line with the implementation and/or python-dev discussions.
862
Tim Peters8dc73d22006-04-24 02:03:16 +0000863- Bug #1337990: clarified that ``doctest`` does not support examples
864 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000867What's New in Python 2.5 alpha 1?
868=================================
869
Anthony Baxterebed3f62006-04-03 15:03:44 +0000870*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000871
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000872Core and builtins
873-----------------
874
Nick Coghlan43832302006-04-23 17:04:07 +0000875- PEP 338: -m command line switch now delegates to runpy.run_module
876 allowing it to support modules in packages and zipfiles
877
Martin v. Löwisc661b882006-04-20 04:54:23 +0000878- On Windows, .DLL is not an accepted file name extension for
879 extension modules anymore; extensions are only found if they
880 end in .PYD.
881
Martin v. Löwisea62d252006-04-03 10:56:49 +0000882- Bug #1421664: sys.stderr.encoding is now set to the same value as
883 sys.stdout.encoding.
884
Neal Norwitz92e212f2006-04-03 04:48:37 +0000885- __import__ accepts keyword arguments.
886
Georg Brandlccadf842006-03-31 18:54:53 +0000887- Patch #1460496: round() now accepts keyword arguments.
888
Anthony Baxter262c00a2006-03-30 10:53:17 +0000889- Fixed bug #1459029 - unicode reprs were double-escaped.
890
Hye-Shik Changd478f342006-03-23 12:32:36 +0000891- Patch #1396919: The system scope threads are reenabled on FreeBSD
892 5.4 and later versions.
893
Neal Norwitze98ccf62006-03-23 05:39:47 +0000894- Bug #1115379: Compiling a Unicode string with an encoding declaration
895 now gives a SyntaxError.
896
Georg Brandlabd1ff82006-03-18 07:59:59 +0000897- Previously, Python code had no easy way to access the contents of a
898 cell object. Now, a ``cell_contents`` attribute has been added
899 (closes patch #1170323).
900
Tim Peterscf79aac2006-03-16 01:14:46 +0000901- Patch #1123430: Python's small-object allocator now returns an arena to
902 the system ``free()`` when all memory within an arena becomes unused
903 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
904 freed. Some applications will see a drop in virtual memory size now,
905 especially long-running applications that, from time to time, temporarily
906 use a large number of small objects. Note that when Python returns an
907 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000908 platform C library will in turn return that memory to the operating system.
909 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000910 appears to be effective at least on Microsoft C and gcc-based systems.
911 Thanks to Evan Jones for hard work and patience.
912
Georg Brandl533ff6f2006-03-08 18:09:27 +0000913- Patch #1434038: property() now uses the getter's docstring if there is
914 no "doc" argument given. This makes it possible to legitimately use
915 property() as a decorator to produce a read-only property.
916
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000917- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
918 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
919 of requiring an int or long in slicing and a few other contexts, enabling
920 other objects (e.g. Numeric Python's integers) to be used as slice indices.
921
Neal Norwitz995acdf2006-03-07 05:01:00 +0000922- Fixed various bugs reported by Coverity's Prevent tool.
923
Brett Cannonbf364092006-03-01 04:25:17 +0000924- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
925 new exception base class, BaseException, which has a new message attribute.
926 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
927 Raising a string exception now raises a DeprecationWarning.
928
Thomas Woutersfb609f42006-02-28 16:37:25 +0000929- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
930 explicitly relative, using 'from .module import name' to mean 'from the same
931 package as this module is in. Imports without dots still default to the
932 old relative-then-absolute, unless 'from __future__ import
933 absolute_import' is used.
934
Brett Cannona7446e32006-02-27 23:39:10 +0000935- Properly check if 'warnings' raises an exception (usually when a filter set
936 to "error" is triggered) when raising a warning for raising string
937 exceptions.
938
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000939- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000940 The name was removed from Include/code.h.
941
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000942- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000943
Guido van Rossum1968ad32006-02-25 22:38:04 +0000944- Patch 1433928:
945 - The copy module now "copies" function objects (as atomic objects).
946 - dict.__getitem__ now looks for a __missing__ hook before raising
947 KeyError.
948
Tim Peters84ef21c2006-02-28 20:39:06 +0000949- PEP 343: with statement implemented. Needs ``from __future__ import
950 with_statement``. Use of 'with' as a variable will generate a warning.
951 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000952 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000953 The following objects have __context__ methods:
954 - The built-in file type.
955 - The thread.LockType type.
956 - The following types defined by the threading module:
957 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
958 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000959
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000960- Fix the encodings package codec search function to only search
961 inside its own package. Fixes problem reported in patch #1433198.
962
963 Note: Codec packages should implement and register their own
964 codec search function. PEP 100 has the details.
965
Tim Peters9ea89d22006-06-04 03:26:02 +0000966- PEP 353: Using ``Py_ssize_t`` as the index type.
967
968- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
969 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
970 now allow Python to make use of memory blocks exceeding 2**32 bytes for
971 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
972 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000973
Neal Norwitzfc76d632006-01-10 06:03:13 +0000974- Patch #1400181, fix unicode string formatting to not use the locale.
975 This is how string objects work. u'%f' could use , instead of .
976 for the decimal point. Now both strings and unicode always use periods.
977
Neal Norwitz671b9e32006-01-09 07:07:12 +0000978- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
979 configure would break checking curses.h.
980
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000981- Bug #959576: The pwd module is now builtin. This allows Python to be
982 built on UNIX platforms without $HOME set.
983
Neal Norwitzc10978f2005-12-19 06:07:16 +0000984- Bug #1072182, fix some potential problems if characters are signed.
985
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000986- Bug #889500, fix line number on SyntaxWarning for global declarations.
987
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000988- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
989
Neal Norwitze7214a12005-12-18 05:03:17 +0000990- Support for converting hex strings to floats no longer works.
991 This was not portable. float('0x3') now raises a ValueError.
992
Barry Warsaw2a38a862005-12-18 01:27:35 +0000993- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000994 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000995 is now displayed in interactive prompt banner.
996
Georg Brandlfa166682005-12-17 21:45:17 +0000997- Implementation of PEP 341 - Unification of try/except and try/finally.
998 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000999 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001000
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001001- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1002 now encodes backslash correctly.
1003
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001004- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1005
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001006- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001007 and long longs.
1008
Neal Norwitz67715f02005-11-09 06:59:35 +00001009- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001010 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001011 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001012
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001013- Replaced most Unicode charmap codecs with new ones using the
1014 new Unicode translate string feature in the builtin charmap
1015 codec; the codecs were created from the mapping tables available
1016 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1017 encodings now include a mapping for the Apple logo)
1018
Tim Peterse3547fd2005-12-16 23:13:57 +00001019- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001020
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001021- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001022
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001023- A new AST parser implementation was completed. The abstract
1024 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001025 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001026
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001027- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001028 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1029
Neal Norwitz708e51a2005-10-03 04:48:15 +00001030- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1031
Neal Norwitz11bd1192005-10-03 00:54:56 +00001032- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1033 Provide a warning when a directory is passed on the command line.
1034
Neal Norwitz40d37812005-10-02 01:48:49 +00001035- Fix segfault with invalid coding.
1036
1037- SF bug #772896: unknown encoding results in MemoryError.
1038
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001039- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001040 supported a __len__() method which evaluated to False when the iterator
1041 was empty.
1042
Guido van Rossum630db602005-09-20 18:49:54 +00001043- On 64-bit platforms, when __len__() returns a value that cannot be
1044 represented as a C int, raise OverflowError.
1045
Skip Montanarof8948ca2005-09-19 03:54:46 +00001046- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001047 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001048
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001049- SF bug #893549: parsing keyword arguments was broken with a few format
1050 codes.
1051
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001052- Changes donated by Elemental Security to make it work on AIX 5.3
1053 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1054 bug #105470: test_pwd fails on 64bit system (Opteron).
1055
Guido van Rossum539c6622005-09-14 17:49:54 +00001056- Changes donated by Elemental Security to make it work on HP-UX 11 on
1057 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1058
Georg Brandl4550b8d2005-08-26 06:43:52 +00001059- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001060 (fixes bug #1119418).
1061
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001062- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1063
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001064- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1065 exceptions that cause a function to exit.
1066
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001067- The implementation of set() and frozenset() was revised to use its
1068 own internal data structure. Memory consumption is reduced by 1/3
1069 and there are modest speed-ups as well. The API is unchanged.
1070
Tim Petersde7990b2005-07-17 23:45:23 +00001071- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1072
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001073- SF bug #1229429: PyObject_CallMethod failed to decrement some
1074 reference counts in some error exit cases.
1075
Tim Petersecc6e6a2005-07-10 22:30:55 +00001076- SF bug #1185883: Python's small-object memory allocator took over
1077 a block managed by the platform C library whenever a realloc specified
1078 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001079 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001080 portable way to copy data from the C-managed block into Python's
1081 small-object space without risking a memory fault. Python's small-object
1082 realloc now leaves such blocks under the control of the platform C
1083 realloc.
1084
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001085- SF bug #1232517: An overflow error was not detected properly when
1086 attempting to convert a large float to an int in os.utime().
1087
Raymond Hettinger3296e692005-06-29 23:29:56 +00001088- SF bug #1224347: hex longs now print with lowercase letters just
1089 like their int counterparts.
1090
Michael W. Hudson188d4362005-06-20 16:52:57 +00001091- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1092 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1093 interpreter states; back out that fix and do a better job (see
1094 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1095 for a longer write-up of the problem).
1096
Michael W. Hudsondf888462005-06-03 14:41:55 +00001097- SF patch #1180995: marshal now uses a binary format by default when
1098 serializing floats.
1099
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001100- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1101 the routines that promise to produce IEEE 754 binary representations
1102 of floats now simply copy bytes around.
1103
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001104- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1105 278.
1106
Brett Cannonc3647ac2005-04-26 03:45:26 +00001107- patch #1109424: int, long, float, complex, and unicode now check for the
1108 proper magic slot for type conversions when subclassed. Previously the
1109 magic slot was ignored during conversion. Semantics now match the way
1110 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001111 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001112 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001113 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001114
Barry Warsawc8d907c2005-04-19 23:43:40 +00001115- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1116 NULL, now raise an AttributeError when attempting to set or delete the
1117 attribute. Previously a TypeError was raised, but this was inconsistent
1118 with the equivalent pure-Python implementation.
1119
Michael W. Hudson774479c2005-04-18 08:46:17 +00001120- It is now safe to call PyGILState_Release() before
1121 PyEval_InitThreads() (note that if there is reason to believe there
1122 are multiple threads around you still must call PyEval_InitThreads()
1123 before using the Python API; this fix is for extension modules that
1124 have no way of knowing if Python is multi-threaded yet).
1125
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001126- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1127 disabled caused a crash.
1128
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001129- Bug #1165306: instancemethod_new allowed the creation of a method
1130 with im_class == im_self == NULL, which caused a crash when called.
1131
Tim Petersecc6e6a2005-07-10 22:30:55 +00001132- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001133 fixes the crash seen in bug #1165761
1134
Raymond Hettinger96229b12005-03-11 06:49:40 +00001135- Added two new builtins, any() and all().
1136
Brett Cannon409d8f22005-03-05 06:47:57 +00001137- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001138 (e.g., ``class C(): pass`` is no longer a syntax error).
1139 Patch #1176012 added support to the 'parser' module and 'compiler' package
1140 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001141
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001142- Patch #1115086: Support PY_LONGLONG in structmember.
1143
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001144- Bug #1155938: new style classes did not check that __init__() was
1145 returning None.
1146
Tim Petersecc6e6a2005-07-10 22:30:55 +00001147- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001148 ('\') with a specific error message.
1149
Martin v. Löwisff232d72005-03-03 09:24:38 +00001150- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1151
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001152- Bug #1124295: the __name__ attribute of file objects was
1153 inadvertently made inaccessible in restricted mode.
1154
Tim Petersecc6e6a2005-07-10 22:30:55 +00001155- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001156 an ferror() call.
1157
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001158- min() and max() now support key= arguments with the same meaning as in
1159 list.sort().
1160
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001161- The peephole optimizer now performs simple constant folding in expressions:
1162 (2+3) --> (5).
1163
Raymond Hettingera422c342005-01-11 03:03:27 +00001164- set and frozenset objects can now be marshalled. SF #1098985.
1165
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001166- Bug #1077106: Poor argument checking could cause memory corruption
1167 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001168
Jeremy Hyltonab630502005-02-04 18:44:06 +00001169- The parser did not complain about future statements in illegal
1170 positions. It once again reports a syntax error if a future
1171 statement occurs after anything other than a doc string.
1172
Neil Schemenauercf52c072005-08-12 17:34:58 +00001173- Change the %s format specifier for str objects so that it returns a
1174 unicode instance if the argument is not an instance of basestring and
1175 calling __str__ on the argument returns a unicode instance.
1176
Tim Petersf4e69282006-02-27 17:15:31 +00001177- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1178 current thread state when the auto-GIL-state machinery knows about
1179 it (since the thread state is being deleted, continuing to remember it
1180 can't help, but can hurt if another thread happens to get created with
1181 the same thread id).
1182
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001183Extension Modules
1184-----------------
1185
Georg Brandl43f08a82006-03-31 18:01:16 +00001186- Patch #1380952: fix SSL objects timing out on consecutive read()s
1187
Neal Norwitz05a45592006-03-20 06:30:08 +00001188- Patch #1309579: wait3 and wait4 were added to the posix module.
1189
Anthony Baxterfa869072006-03-20 05:21:58 +00001190- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1191 In addition, the existing ulaw code was updated.
1192
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001193- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001194 now exposed via new attributes.

1359
Raymond Hettingerb2594052004-12-05 09:25:51 +00001360- itertools.islice() now accepts None for the start and step arguments.
1361 This allows islice() to work more readily with slices:
1362 islice(s.start, s.stop, s.step)
1363
Skip Montanaro0af3ade2005-01-13 04:12:31 +00001364- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001373- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1374 been renamed to have only a single underscore prefix. This was done to
1375 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001376
Nick Coghlan43832302006-04-23 17:04:07 +00001377- PEP 338: new module runpy defines a run_module function to support
1378 executing modules which provide access to source code or a code object
1379 via the PEP 302 import mechanisms.
1380
Anthony Baxter93f5b932006-04-03 08:05:07 +00001381- The email module's parsedate_tz function now sets the daylight savings

1389 in attribute values.
1390
Anthony Baxterc51ee692006-04-01 00:57:31 +00001391- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001392 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001393 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001394 module will not be built.
1395
Tim Petersc17976e2006-04-01 00:26:53 +00001396- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1397 aren't officially supported here, and trying to use them will probably
1398 raise an exception some day. But dicts have been allowed, and "mostly
1399 worked", so support for them won't go away without warning.
1400
Georg Brandl338ef7d2006-03-31 18:42:16 +00001401- Bug #1445068: getpass.getpass() can now be given an explicit stream
1402 argument to specify where to write the prompt.
1403

1419
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001420- email 4.0 package now integrated. This is largely the same as the email 3.0
1421 package that was included in Python 2.3, except that PEP 8 module names are
1422 now used (e.g. mail.message instead of email.Message). The MIME classes
1423 have been moved to a subpackage (e.g. email.mime.text instead of
1424 email.MIMEText). The old names are still supported for now. Several
1425 deprecated Message methods have been removed and lots of bugs have been
1426 fixed. More details can be found in the email package documentation.
1427
Walter Dörwald40108c92006-03-27 08:15:44 +00001428- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1429 (a subclass of tuple) that provides incremental decoders and encoders
1430 (a way to use stateful codecs without the stream API). Python functions
1431 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1432 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1433 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001435- Patch #1359365: Calling next() on a closed StringIO.String object raises
1436 a ValueError instead of a StopIteration now (like file and cString.String do).
1437 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1438 called before (like file and StringIO.StringIO do).

1514 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1515 Ronald L. Rivest offered this advice for Python:
1516
1517 "The consensus of researchers in this area (at least as
1518 expressed at the NIST Hash Function Workshop 10/31/05),
1519 is that SHA-256 is a good choice for the time being, but
1520 that research should continue, and other alternatives may
1521 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001522

1703 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001704 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001705 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001706 + Dialect parameter parsing has been re-implemented to improve error

1709 dictates.
1710 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001711 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001712 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001713 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1714 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001715 + reader now allows \r characters to be quoted (previously it only allowed
1716 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001717 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001718 + Dialect classes passed to the module are no longer instantiated by
1719 the module before being parsed (the former validation scheme required
1720 this, but the mechanism was unreliable).
1721 + The dialect registry now contains instances of the internal
1722 C-coded dialect type, rather than references to python objects.
1723 + the internal c-coded dialect type is now immutable.
1724 + register_dialect now accepts the same keyword dialect specifications
1725 as the reader and writer, allowing the user to register dialects
1726 without first creating a dialect class.
1727 + a configurable limit to the size of parsed fields has been added -
1728 previously, an unmatched quote character could result in the entire
1729 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001730 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001731 the parser field size limit (returning the former limit). The initial
1732 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001733 + A line_num attribute has been added to the reader object, which tracks
1734 the number of lines read from the source iterator. This is not
1735 the same as the number of records returned, as records can span
1736 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001737 + reader and writer objects were not being registered with the cyclic-GC.
1738 This has been fixed.
1739
Brett Cannone6539c42005-01-08 02:43:53 +00001740- _DummyThread objects in the threading module now delete self.__block that is
1741 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1742 lock primitives tend to be limited in number and thus should not be wasted on
1743 a _DummyThread object. Fixes bug #1089632.
1744
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001745- The imghdr module now detects Exif files.
1746
Raymond Hettinger6065d322004-12-20 23:51:53 +00001747- StringIO.truncate() now correctly adjusts the size attribute.
1748 (Bug #951915).
1749
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001750- locale.py now uses an updated locale alias table (built using
1751 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1752 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001753 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001754
Raymond Hettinger3557f422004-12-07 12:02:02 +00001755- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1756
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001757- the pickle module no longer accepts the deprecated None option in the
1758 args tuple returned by __reduce__().
1759
Brett Cannon84667c02004-12-07 03:25:18 +00001760- optparse now optionally imports gettext. This allows its use in setup.py.
1761
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001762- the pickle module no longer uses the deprecated bin parameter.
1763
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001764- the shelve module no longer uses the deprecated binary parameter.
1765

1767
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001768- the filecmp module no longer uses the deprecated use_statcache argument.
1769
Raymond Hettinger664347b2004-12-04 21:21:53 +00001770- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1771 extended or overridden by subclasses. Formerly, the subclassed method would
1772 be ignored by the rest of the module. (Bug #1078905).
1773
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001774- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001775 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001776
Walter Dörwald36733692004-12-22 12:50:50 +00001777- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1778 once when a size argument is given. This prevents a buffer overflow in the
1779 tokenizer with very long source lines.
1780
Barry Warsaw538561e2006-01-01 21:48:54 +00001781- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1782 immediately after creating the object, without any intervening
1783 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001784
Skip Montanaro05885812005-01-16 20:48:27 +00001785- The reconvert.quote function can now emit triple-quoted strings. The
1786 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001787
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001788- ``UserString.MutableString`` now supports negative indices in
1789 ``__setitem__`` and ``__delitem__``
1790
Greg Ward40407942005-03-05 02:53:17 +00001791- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1792 correctly.
1793
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001794- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1795 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1796 character even if the user has passed a size parameter to get a proper
1797 line ending. Remove the special handling of a "\r\n" that has been split
1798 between two lines.
1799
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001800- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1801 about illegal code points. The codec now supports PEP 293 style error
1802 handlers.
1803
Walter Dörwald78a78b02005-09-01 12:04:29 +00001804- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001805 from the input stream, so that the output is a byte string in the correct
1806 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001807
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001808- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1809 considering it exactly like a '*'.
1810
Walter Dörwald007f8df2005-10-09 19:42:27 +00001811- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1812 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001813
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001814- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1815
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001816- Patch #1413711: Certain patterns of differences were making difflib
1817 touch the recursion limit.
1818
Walter Dörwald58917a62006-03-31 15:26:22 +00001819- Bug #947906: An object oriented interface has been added to the calendar
1820 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001821 called as a script (e.g. via ``python -mcalendar``). Localized month and
1822 weekday names can be ouput (even if an exotic encoding is used) using
1823 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001824
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001825Build
1826-----
1827
Neal Norwitz602d3392006-03-31 08:21:40 +00001828- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1829 by using -mieee gcc option.
1830
Martin v. Löwis86d66262006-02-17 08:40:11 +00001831- Patch #1432345: Make python compile on DragonFly.
1832
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001833- Build support for Win64-AMD64 was added.
1834
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001835- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1836
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001837- Patch #881820: look for openpty and forkpty also in libbsd.
1838
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001839- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1840 The zlib module is now builtin on Windows.
1841
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001842- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1843
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001844- Bug #1189330: configure did not correctly determine the necessary
1845 value of LINKCC if python was built with GCC 4.0.
1846
Trent Mick8321b422005-07-26 02:29:21 +00001847- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1848 vulnerability in zlib 1.2.1 and 1.2.2.
1849
Brett Cannon08cd5982005-04-24 22:26:38 +00001850- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1851 flags that change binary compatibility. Changes were also made to
1852 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001853 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001854
Bob Ippolitoed233462005-03-29 13:47:59 +00001855- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1856 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1857 no longer exists). This configure patch makes things right.
1858
Martin v. Löwise2713be2005-03-08 15:03:08 +00001859- Bug #1158607: Build with --disable-unicode again.
1860
Brett Cannon46d96232005-02-16 00:07:19 +00001861- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1862 defined. Discovered as a result of not being able to build on OS X.
1863
Brett Cannon516592f2004-12-07 00:42:59 +00001864- setup.py now uses the directories specified in LDFLAGS using the -L option
1865 and in CPPFLAGS using the -I option for adding library and include
1866 directories, respectively, for compiling extension modules against. This has
1867 led to the core being compiled using the values in CPPFLAGS. It also removes
1868 the need for the special-casing of both DarwinPorts and Fink for darwin since
1869 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1870 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1871 Fink, ``-I/opt/local/include`` for DarwinPorts).
1872
Brett Cannon43802422005-02-10 20:48:03 +00001873- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1874 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1875 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1876 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001878C API
1879-----
1880
Tim Petersc9d78aa2006-03-26 23:27:58 +00001881- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1882 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1883 is obtained via the ``PyObject_`` family, it must be released via the
1884 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1885 always been officially true, but when Python's small-object allocator was
1886 introduced, an attempt was made to cater to a few extension modules
1887 discovered at the time that obtained memory via ``PyObject_New`` but
1888 released it via ``PyMem_DEL``. It's years later, and if such code still
1889 exists it will fail now (probably with segfaults, but calling wrong
1890 low-level memory management functions can yield many symptoms).
1891
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001892- Added a C API for set and frozenset objects.
1893
Raymond Hettinger66517482004-12-03 11:45:13 +00001894- Removed PyRange_New().
1895
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001896- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1897 mapping argument now. This string is used as a mapping table. Byte values
1898 greater than the length of the string and 0xFFFE are treated as undefined
1899 mappings.
